L502X modded bioses download (GPU voltages and more!)

@mfox143

lol, your reply is not irrelevant, and also welcome to the forums

glad to know it helped your temps decreased a lot

well, relating league of legends fps drop.

I also play league of legends, I noticed it updated yesterday, but didnt played after it yet.

so my advice is the same I gave to another guys who asked for extra performance on League of Legends:

setting the max prerendered frames to 8 improves performance a lot.

more details here:

http://forum.notebookreview.com/del...ed-bioses-download-gpu-voltages-more-234.html

also check the machine is on max performance, both cpu, and cpu options in bios, windows and other software like nvidia control panel.

check there are no other apps taking system resources.

that should improve general performance.

about crashes, well, if you are already using a modded bios with undervolt. (if posible the latest version v6) and it still crashing, try updating drivers to the latest version.

if that doesnt help, you may need to underclock your gpu a little, this affects performance, but as for many users, it is required even it is the last resource.

 

thanks for the suggestion.

will test it out once i understand how to use nvidia inspector. ahahaha

ill have to test 4 prerendered frames for now (all nvidia control panel would allow)

P.S. will get back to this thread as soon as i get results )

 

nvidia control panel doesnt let you choose 8 prerendered frames, that is why you need nvidia inspector, all you need is open it, click at the tools icon, and when the games profiles window load, look for league of legends and follow the instructions I pointed

 

@capitan kasar

tried out 2 games in a row @ 4 prerendered frames, good enough that i dont get those big fps drops from 150 to 20.. ahaha now the fps drops are 60 minimum. and i cant even feel the drop ) (as compared to before where i couldnt even cast a skill during clashes)

wooo will try out 8 prerendered frames now.. be back in a sec ahahaha

 

done with the 8 prerendered frames.. didnt see much difference in game.. i think i will stick with 4 frames for now. )

BTW, can you please list out tools i would need for a complete overhaul of the L502x, (been planning to repaste, but dont have the tools)..

the usual guides i see are step by step, by they dont really say what tool i need to do this or do that ))) thanks in advance )

 

@mfox143

mmm, in my case, it was ok with just a little screwdrivers to take appart the unit (not sure if this is what you mean ^^)

mostly small ones from cross or plain form.

a trick part is also to remove the palmrest, but after several openings, I just noticed you dont even need an app to open it , just use your claws/nails to try pull up the palmrest from near the power button from the keyboard side, not from outside, it will get out easly slowly

I also will take appart the unit in a few days when some parts arrive:

I'm planning to do:

* proccesor upgrade
* add heatsinks to voltage regulators
* add another usb internal mod
* repaste and clean the dust from the unit.

about the guides, I saw someones but many of them have dead image links.

my advice is that you try to work in a clean desk with a lot of space, you will need to put the parts and screws in order so you know exactly what part was from where ^^

 

oh just screw drivers.. ahaha yeah, i tried opening it up last month (just got curious what was inside + wanted to clean it)..

i was already-removed-the-keyboard-and-HDD deep that time. and then i realized there was nothing to clean there, and was too afraid to go heatsink-deep.

so even after that stage, all i need are a couple of screw drivers? awesome then.. hahahaha

thanks for the advice!

 

yeah, you dont need extra stuff.

well, anyway I recomend some kind of cloth or fabric to put over the screen while tou take it appart, I supose you dont like scratches over the screen, right? ^^

also, if you are going to remove the cpu heatsink, then you will need some paper and alchool to clean previous paste, and also will need new paste to apply over it.

you can use previous paste and place it at the middle of the chip with a card or something wich prevent you to touch it directly with your fingers.


however yeah, remove the heatsink is a little annoying, well, I will have no choice since I am going to replace the CPU

however my temps were already good.

well, lets hope they will get even better after this repaste, hehehe ^^

 

I formated the laptop and I got this usb disabled on boot problem again. I have a dying battery, newer me firmware and modded bios and a new logitech usb headset. I have yet to find out this problem since it happens randomly.

It happens when I shut down pc and turn of adapter, then come back and turn on pc after turning on laptop adapter, I find my usb ports completely disabled, restarting pc fixes it.

 

Reverted back to default bios. Next a week to see if it happens again.

 

Czesc agalin.

Mam do Ciebie wielką prośbę.
Posiadam takiego samego laptopa, jak ten, który masz w opisie. Parametry indentyczne z wyjątkiem HDD. Od kilku godzin i bez skutku zmagam sie z instalacja Mac OsX Mavericks na dysku MBR, który posiada już Windows 8.1 i Ubuntu. Powiedz mi proszę, jakim cudem udało Ci sie zainstalować Maverica?
U mnie ciągle wyskakują błędy .
Nie chcę formatowac i konwertowac dysku z MBR do GPT (GUID) tylko dla OsX, ale może innego wyjścia nie ma? Jakiej metody i wersji Maverica użyłeś/aś do Instalacji? I jakie ustawienia w Biosie?
Z niecierpliwością czekam na odpis i z góry dzięki!

Hi guys,

I was wondering if you could shed any light on a problem I have with my i7 2670QM, when using CPU-Z and Intel's processor diagnostic tool my CPU core speed is at 798mhz? I'm not sure what's wrong, I've disabled speedstep in the BIOS, I've tried disabling the extended C states, I've even tried turning all the performance options right up in the power options, but it will not budge. I've got one of capitankasar's modded BIOS from this thread, and I've done everything advised (fast strings, fast boot etc), I also tried reverting back to Dell's stock A12 BIOS and still nothing changed.

As I said, I'm getting 798mhz on CPU-Z, and when I run a stress test of any sort it stays the same, slightly fluctuates between 797-798mhz, surely I should see this rise to 2.2-3.2ghz right?

This is the reading I get on Intel's diagnostics:

Can anyone shed any light on this? I'm worried my processor is either knackered or I'm missing something.

 

@ windowsappme

let us to know how if you keep having issues with the usb.

anyway I never experienced those kind of issues with original or modded bios.

only times the usb ports stoped working were once, while I took appart the laptop and forgot to connect one of the small data ribbons.

I fixed it by took appart the whole laptop again and connecting the ribbon.

@davephl

posting in english may help others to understand what you say

@Jimbobbeers

try also disable "dynamic fsb" in the bios unlocked proccesor options

it helped to keep my i3 on max frecuency while also disabling c states and speedstep

check also your cpu is not overheated (well, to be honest I dont think that is the issue with 42º C), and check also windows power plans, everything should be set to performance, and its also recomendable having the laptop plugged in to the wall in order to archive better performance.


I also suggest to give a try to throotlestop software to force the proccesor speed.

 

Hi capitankasar,

Thanks for your advice, I'll give all that a go tonight. Also one thing I forgot to mention, my AC Charger is playing up. What I mean by this is that it will power the laptop but it won't charge the battery and everytime I start the laptop I get a warning on the desktop telling me:

'The AC power adapter type cannot be determined.

Your system will operate slower and battery will not charge.

This problem might be solved by:

•Ensure the plug is inserted completely for best system operation.
•Connect a Dell 130W adapter or higher'

Now, I've just read amongst the internet ( Bypassing the DELL unrecognized adapter issue) that Dell automatically cut CPU performance in half when this occurs, as it believes a non genuine adaptor is plugged in (even though it is the original) so this could expalin my problem. So I've plenty to do tonight!

Thanks again.

 

@Davephl
Skoro zacząłeś po polsku...
Mavericks z MBR nie instalowałem. Miałem tak tylko Mountain Liona. Ale procedura powinna być podobna. Poprawny DSDT, SSDT i konfiguracja bootloadera. GPT jest o tyle łatwiejsze, że Clover działa tam bez trudu. Ale chyba jest też jakaś wersja pod MBR. Jednak nawet z innym bootloaderem powinno dać radę. ML miałem z Chameleonem i hulał. Jaki konkretnie masz problem? Startuje Ci w ogóle instalator? Jeżeli nie, to jakich flag próbowałeś? Pierwsze uruchomienie PO instalacji ML u mnie poszło z -x, dopiero po zainstalowaniu DSDT itp. działał normalnie. Co do kextów polecam tą paczkę (mam nadzieję, że nie łamię regulaminu xD): wersja 1.4 - większość z tego instaluję też na Mavericks i wszystko działa. Nie polecam natomiast sterownika do PS2 - najnowsza wersja z Gita dewelopera lepiej mi się sprawuje. Ale DSDT i SSDT z tej paczki potrafią zdziałać cuda po prostu.
Co do konfiguracji BIOSu: w ML miałem domyślną z włączonym/wyłączonym (zależnie od momentu) Fast Strings. W Mavericks mam włączone UEFI (inaczej nie uruchomisz z dysku GPT no i żeby wykorzystać Clover), Fast Strings i jeszcze wyłączone oszczędzanie energii dla SSD, bo dziwne rzeczy się z Windowsem czasami działy.

@capitankasar he has asked how I have installed successfully OS X Mavericks on my machine as he has nearly the same config as I have.He has MBR config and 2 other OSs so he doesn't want to reformat drive as GPT and already he failed many times trying to install OS X.
Oh! And I didn't translate my message to him too! Sorry for that
I've never installed Mavericks on MBR.Only Mountain Lion, but procedure should be the same. Correct DSDT, SSDT and bootloader config. GPT is much easier because there is Clover without any problems. I'm not sure, but I heard about MBR version too. But even with other bootloader it should work. I had ML with Chameleon.and it worked. What is the problem specifically? Does installation even start? If not, which flags have you used? First run after installation of ML I needed -x flag to work and it worked correctly after proper DSDT etc. had been installed. For kexts I think that this package is the best (and I hope not to broke any forum rule xD): version 1.4 - most of them I install on Mavericks too. PS2 driver is better from developer's Git for me. But DSDT and SSDT from this pack are wonderful.
About BIOS: with ML I had only enabled/disabled (both tested) Fast Strings. For Mavericks needed UEFI (GPT boot only possible with that and Clover required EFI), had Fast Strings (both too) and disabled power management for SSD because there were strange things on Windows sometimes.

 

@Jimbobbeers

let us to know if you have success

@agalin

oh, its ok, well, it could be better if we all talk on english, but if you can help him it would be nice


also my native language is spanish

I understand some english a very little french, but sadly nothing more.

so my language skills are way limited ^^

 

Well I didn't have much time last night but I managed to sort it. I tried RMClock and failed miserably, it wouldnt recognise the i7 2670QM, so I couldn't really do anything with it, although oddly it was showing my processor clock at 2.2, yet every other piece of software shows 798mhz. I also tried disabling dynamic fsb, which also made no difference.

So I tried what you suggested, Throttlestop. I unchecked BD PROCHOT and bam, my processor shot straight up to 2.2ghz. So thank you for your suggestion.

I have a couple of questions mind you...

1. Is it possible for Throttlestop to kick in on startup? (instead of me having to open it everytime)

2. Now I've got the processor to it's correct speed, obviously it's capable of speeds of up to 3.1 - 3.2ghz, when running a stress test or any demanding applications it appears to stay at 2.2ghz, is there a way to force it to use the turbo boost?

 

@Jimbobbeers

well, throttlestop is just like a temporal patch for you.

however you need to fix that charger issue (did you tested another charger?)

you can try some stuff to easy run the app:

* when the app is running, roght click on the program bar icon and click "attach/lock to the bar" (not sure if on english windows version it will run like that)

* you can download any software wich let to run programs at startup, then just add this executable.
give a read to this:
How to add a program to startup - Microsoft Community


well, relating turboboost, I think dell included an utility relating turboboost, and also throtle stop have options for it.

sadly I just have an i3 without that feature, but I ordered a used I5 upgreade for very little money, so as soon it will arrive I will be able to start testing the turbo feature and experiment with software.



@all

hey all I may have some good news for you

if this work, this will bring overclocking for ALL people, it does not matter if you havent done hardware mods. (only if following work)

not sure, but this may interest everyone with a locked descriptor (most people in here except me and two guys who hardmodded the machine)

I think I may have been found a way to soft-bypass the descriptor settings, this will allow enable overclocking without the need of hardware mods.

however, I need testers (it worked for me, but since my descriptor were already unlocked, it isnt a valid test)

I made a small pack of software and instructions for all interested people on testing this on their L502X

https://www.mediafire.com/?rm527y5iux7s3wc


requirements:

* any usb stick (this package will make it a DOS bootable usb stick)

warning: the contents of the usb stick will be deleted on the process, make sure you backup them somewhere!


preparation:

* download and extract the contects of the package.

* run HPUSBFW_original.EXE

in the app, select:
select the usb device
FAT32
set a label for your drive (optional)
tick create a DOS disk option, you will need also to select the MSDOS folder to get this option working.


example:



while done, click on start


while done, close the window, and copy the "contents" of the "flash files to the root of the new DOS bootable root directory.


procedure:

1 - turn off the machine
2 - enter on the bios, ensure uefi option is disabled and usb storage devices is at the top of the boot priority (you can boot it also using the F12 menu)
3 - turn off the machine
4 - make sure the usb stick is plugged in
5 - turn on the machine
6 - if everything ran fine, you should now be booting from the usb stick
7 - after the DOS command prompt loaded tyle "flash.bat" or just "flash" (without the quotes)
8 - then follow the instructions (first it will run the test software, if that worked, then the next steps will work, the next steps are: a total backup of your flash to a file, and it will flash the latest overclocking patch I made)


feedback please

 

If this patch doesn't work, it'll brick our BIOS, yes? So it'd be better to have copy possible to flash with programmer (as it tries to write into locked section, normal flash from recovery wouldn't fix it) am I right?

I don't know many languages too. Only Polish and English, so you're better. And that's why I have translated both messages.

 

@agalin

if this patch doesnt work, it will just give read or write access error, like it was happening before on windows while trying to access locked descriptor machines with fptw64 software

also, this test script make automatically backup of the chip contents wich can be used later in case of something goes wrong. (the backup is made obiusly only in case the test app bypassed the security, if not, it will just give an error while trying to access flash to backup)

also the content to be flashed (me overclocking patch) has been tested by me.


I just need to know if this bypass security for locked descriptor users.

if this works for you, I can relase later another patch wich unlock the descriptor forever, so it can be accesed from windows too.


but, for that, I need someone to test it (if posible someone without a hardware mod to bypass the descriptor, probably most of people here except me and very very few people have locked descriptor, as it is locked by default ^^)

 

Hi everyone , cap i think i got bad news for ya:
my bios mod didnt work ( at least it didnt brick ) the voltages are not working , it will either go to 1v (causing the display driver error) on 3d profile or stay at 0.83 (doesnt matters if im playing a game or not it just locks itself there , happens with less frequency) and lock nvidia at 208mhz

Quick edit : forgot to mention im using the v6 a12 bios with 3d as 0.85v and 2d as 0.83v

 

@DSKEAARSR 2013

while the driver crash, it "lock" the GPU to those low speeds, only way to remove the lock is reboot , or sometimes disable and reenable the driver from the devices manager do the trick.

are you sure it isnt working?

try using hwmonitor, I'm am almost sure I double checked every bios voltage before pack it.

there are some drivers/apps wich report weird voltages, but hwmonitor usually is accurate with it

wich GPU you have? 540m or 525m?

540m is usually the one with the issues due the higher clock is unstable for some users and they have to underclock it or make mods wich improve stability

my modded bios offer voltage tweaks, as for the 540m the 0.83v/0.85v is usually the one who give best results, however, for some people it just improve things, but not fully fix it.

so many people do still need to underclock its card even using a modded bios.

also after years of use, the card doesnt handle the same clocks like before, so in my case I had to lower the overclock of my 525m after two years of use.

before It ran fine over 700 mhz, now it get stable only on 650 mhz

if the bios doesnt fix the problem for you, try underclock a little by little until it stop crashing.

and if you feel like you can do some mods to the unit, try what has been discused before, adding voltage regulators to the unit,repaste, clean the dust from the heatsinks, and remove the dust filters.

that should

 

Thanks for quick reply , im using gpu-z , and i have a 540m , its saying that my voltage when gaming goes up to 1v with the bios mod that should make it use only 0.85v
about the underclocking the voltage works for about 30 min ( 0.85v) while underclocked but after that it goes up to 1v and it crashes , underclocking doesnt solve the problem , already repasted with mx4 thermal paste ( reaaaaaaaaaaaaaly great temps now) the only thing left to do so i can run stock clocks again is put the vregs heatsinks but the rest is all done and re-done with no solution at all , not even a little better just crash after crash with no change

Another quick edit: i tested the 0.83v bios and it locked my performance at 208mhz just like the other bios but not even if i overclock, underclock , it wont change it thinks its my hd3000 and does not speed up

 

just checked the v6 version for 540m 0.83v/0.85v I uploaded, and the nvidia bios looks fine, the voltage settings I added are fine.

it could be that gpu-z readings are wrong, or that newer drivers manage to force specific voltages by someway, but I cant do much more from the bios side.

sadly there isnt too much you can try from those mods, try underclocking more or trying different nvidia drivers.

 

well i already tried each and every single driver avalible for my system ( windows 8.1 ) and none of them solves it, and im very pissed about it , it all began because of a driver update since then i was unable to make it work with stock frequncies and / or underclocked frequencies ( by the way i use driver sweeper after each driver install so the old one doesnt enter in conflict with the new ones )

 

well, didnt tested windows 8 yet, I like windows 7 and doing a new installation will be a lot of work for configure everything again, I also consider that windows 8 development has been done specially for touch screens, as the interface looks like a smartphone

so I cant tell you anything from win 8 since I didnt tested it.

mmm, so aparently it happened from a driver update, it was nvidia one? or another non gpu related driver?

well, it looks a driver issue, so I suggest you to rollback to your last working driver , the one you was before the issues started after update.

however, you may need to fully unistall current one, and all its configurations, while installing also the new drivers (or older ones) there is a checkbox named "correct installation" on the nvidia setup, that reset all gpu configs to default, that may help ^^

 

already tried that , i even went back to win 7 to see if the older drivers would help ( complete reformat ) but same problem
Damm forgot again : it was a nvidia driver

 

mmm, if after formating the whole hard disk and starting from cero still give issues, then it doesnt sounds good at all.

it could be some hardware issue.

well if underclocking gave you better results (more time without crashing=, you may need to underclock more.

I know this is a crappy solution wich affect GPU performance a lot, but well, I dont see too many options for now.

you could try force the fan to full speed, but you said the temps were good after repaste, so that is probly not the cause

 

Well many thanks for the help but ill try those heatsinks on vregs and after that i give up if it doesnt work , i went as far as underclocking it to 400/800/700
and the max that i got was 20 min ( less than my other "stable" clock that is a little higher )

 

Hey captainkasar, you probably don't remember me, but you have recommended me your modded bios on a dell support page, for a few months it worked flawlessly. But now the same problem arises even on the modded bios (A12 0.83v) and underclocked. Do you have any recommendations to me.

 

@capitankasar OK, I'll probably try to use it tomorrow (it's 1:40 AM in Poland ) but before must think if I'm brave enough to flash it if it works...

 

@Mr_Western

mmm, I would give you the same advices I gave to DSKEAARSR 2013, install the latest version of the modded bios, if you are on the gt540m, install the 0.83v/0.85v.

if problems still happening, try some hardware tweaks:

* repaste
* clean the dust from the fan and heatsinks
* remove dust filter
* install small heat sinks over the voltage regulators
* use a cooling pad

as for software, try clean install of nvidia drivers.

check temps are ok.

if nothing of this help, you will have to underclock more .... ):


@agalin


thanks a lot agalin ))

I was starting to think no one was going to test it ^^

I admit I have no peronal interest on this new method since my unit is already hard unlocked and would not bring new beneficts to me , but since most of people are afraid to take appart the unit and people want Overclock options and other interesting options who may require a unlocked unit, I tried to make a new test pack who may works for this

 

Package downloaded, but... still scared something will brick my notebook if read/write is possible. Actually will make USB Stick, but test (if happens) will be later this day

 

well, like I said, I already tested the package on my machine, and the content it flash is already tested.

basically what the package does is:


1 - try to unlock/bypass the descriptor
2 - backup the whole chip to a file into the usb stuck (this only is posible if the bypass worked, else it will output an permision error and nothing will be done)
3 - will flash my modded ME region with the overclocking settings from the usb stick to your laptop flash (this only is posible if the bypass worked, else it will output an permision error and nothing will be done)

 

Hey, pretty interesting stuff you got there, do you think it will also work on Vostro 3450?

 

@HairyCube

well, it is untested yet, but if it works, it will proably open a lot of new gates/doors

as well for your vostro, well, you can try the package, however, you should edit the bat file and remove the part when it flash the ME patched image (as well it only will work probably for the L502X)

however, it shouldnt be hard to make a ME patch for for your vostro if you are able to make a full dump backup of your chip.

just edit the bat file and remove this line

fpt.exe -ME -F L502OCv3.bin

the one you want is this one

fpt.exe -D backup.bin

after you get this backup, it should be easy to get the ME part of the firmware and patch it to enable overclock (if the firmware estructure is similar ^^)

 

Just tried this, and it gave me "Error 26: The host CPU does not have read access to the target flash area"

 

On L502x read error too :/

 

oh, so the bypass didnt worked
that means FPT.exe is trying to access with the descriptor locked.

do you guys remember the output of the prr2.exe?


I made this test script package since I noticed this awesome app from svl7 (prr2.exe)

http://forum.techinferno.com/genera...digitally-signed-circumvent-secure-flash.html
http://forum.techinferno.com/alienware-m17x-aw-17/1964-[m17x-r4]-unlocked-bios-versions.html

it seems to work on another laptops, but it seems we didnt had luck yet,

there are also another tools like meset.exe wich work for machines like clevo.

but we need to still figure a software method to remove/bypass the descriptor lock without the need of hardware mods.


edit:

@HairyCube

did you ran prr2.exe before running fpt?

 

@capitankasar I just used your script. If can check something more with this package which will be useful to you, tell what to do

 

Hey @capitankasar, thanks for the mod, it worked great for a few months with all sorts of games. But then I played Rust, which it crashed on and it sucks because after that crash on rust it started doing the crashes regularly again and I cant play games any more... is there anything you would recommend to do? can it be fixed again? thank you

 

@agalin

thanks

well, there isnt too much to do for now sadly, but well, thanks for the testing ^^

@I am

well, some games are more sensitive than others relating OC.

for example, for dead space games, I have to reduce the clock to 600 mhz, and also the bclk.

this laptop can be unstable some times, the GPU is a little tricky some times.

but yeah, sadly, many times, it can be fixed only by underclocking.

 

Good news for those who have overheating issues but don't want to disassemble this notebook and who's warranty has ended anyway. It's actually possible to remove the dust filter (or at least parts of it so what the air flow would improve) that is on top of the fan from the outside, without disassembling . You can use a needle and a small knife to pick those round filter holes, cut the filter into pieces and pull those pieces out. I did that, and indeed it improved an air flow and made CPU cooler.

I have a question for a capitankasar.

I have installed:
GT540m bios mod for L502X
A11
2D PROFILE: 0.83v
3D PROFILE: 0.85v

At first it helped, but with time I guess it works worse and I have to underclock my card more for it not to crash in games. Is there any point for me to install an advanced version A12 bios with same voltages? Will I get anything from that in games?

Oops, just read this. Yeah, now I'm reducing it to 630 to play TF2. If you have to reduce to 600 in some games as well, then I guess I won't have much more luck then what I have as well. Good thing I don't need much games anymore. Overall I was never happy with this notebook. I'm not going to buy notebooks from Dell anymore.

I saw this "fast strings" setting in a description of this BIOS mod. One user here reported that it has improved Windows Aero performance score for him. Are there any improvements in games from enabling "fast strings" setting?

 

@Beyond One

the voltage will be the same, however, you can benefit from the new features the new bios mod versions offers over the A11 (wich probably just had voltage mod and maybe minor menus unlocking)

the last a12 v6 offer way more features.

also, about the underclock, yes, it is needed, the card suffer some kind of degradation over time, meaning it can not perform like the first day, so the performance will decrease.

as for fast strings, well, it seems to improve the integrated graphics performance a little, probably will improve all the apps performance wich use the intel hd graphics.

 

@Beyond One remember that capitankasar has GT525m, not 540m And you removed dust filters, so maybe it's dust which makes your pc less stable. I'm successfully playing most of games with voltage 0,83/0,83 and OC to 720 (some games needs 710)... Without removing dust filters or repasting. Lucky copy I think

 

Did anyone try to unscrew a bottom cover and just use a notebook like this? Will this help with the air flow? Maybe it would be simpler than removing those bottom filters for summer.

 

@beyond one

you are talking about the dust filters from the small bottom cover.

however, the most noticiable one is the dustfilter under the system fan, that is the one wich block most air.

 

Yes, just removed the cover. Probably made it several more degrees cooler, not a lot (but can't tell for sure as it depends on a load). I've already dealt with that filter under the system fan as I wrote. Unless there's some other filter that can't be seen from the outside?

 

nope, as far I know there are only those filters, the une under the system fan (the one wich take most impact in temperatures) and also the ones at the bottom cover.

there are a total ammount of 3 dustfilters

1 under the system fan

and 2 at the bottom cover.

if you removed all those, there are no more dustfilters pending to be removed.

 

Hey Kasar, thanks for all the work on the mods.

I'm currently using the most updated 0.85v bios for the 525m, but... I'm still having crashes, even with the stock clock. I still get crashes at 550mhz, and at 500mhz it's mildly stable, crashing after an hour or so of gameplay.

My temperatures never go over 74ºC and I have the fan running at 100%. The motherboard was replaced on September, last year, so it is supposed to be new and work properly...

I also cleaned it up a few months ago, so it shouldn't be a dust issue.

However, I still get crashes no matter what I do.
I've tried every kind of solution to it: the modded bios, stock clock and underclocking, scanned against malwares and scanned against viruses (malwarebytes and kaspersky), disabled the windows Tdr, updated the drivers... Nothing seems to work. I also tried your outdated 0.98v bios and the stock bios, both to no avail. Even with stable temperatures (always below 80ºC), it crashes in a few seconds with the high voltages.

Also, I only started trying to use the 525m yesterday. I was relying on the intel hd 3k ever since the notebook came back from dell's repair.

Am I just ****ed with a defective card, or is there anything else I could try?

Thanks.
