L502X modded bioses download (GPU voltages and more!)

@agalin:

I changed the cpu of my last laptop right after i bought it and had dell changing the mainboard after 11 month. The technician didnT complain. He didnt even notice. So if you do all changes/mod without damage dell will not complain.

@kasar:

haha, now its changing the frequency. cpuz(and throttlestop) shows 99.33MHz, when i set it to 99.55MHz in Intel ETU.
Edit: Last time the slider jumped back to 100MHz, now it stays at 99.5463MHz.

 

@kasar YOU don't need any warranty Your work will be better than in Dell.
@gilipollas it's true that there is no warranty (I'm not sure how it's in english...) sticker that breaks after opening all holes of notebook in Dell?
I'm asking because I think about SSD or changing WiFi (Intel hasn't kext for Mac OS....)

 

@agalin, no, there is no sticker.

Wifi you can switch easily since the mpcie slots are directly behind the 'door' on the back. For switching the hdd you need to open the palmrest, which is a little bit tricky when you do it the first time, but i'm pretty sure, dell will never notice.

 

@agalin

hehe, thank you for that, well, not sure about that.
many of my mods I do it at the easy/lazy way.

about my laptop, since it is full of solderings, weird connectors, switches and mods, the tech guys from dell will probably ask wth is that if I bring my lappy some day to their technical support

even dessoldered their chips from the motherboard haha, the ony I am running now is one I got from ebay with a 5 chip package ^^

@gilipollas

well, there is no point of underclocking the laptop via BCLK, things will run slower, and you also may have sync issues and have to use the apps I used to resync the machine.
if you want to OC, I recomend to mod the ME, I included a new section to advanced modding at the first post

will edit it if someone need clearer instructions ^^

 

You may add me to the list on this one as well. Your BIOS mod works great, thank you very much for this! I flashed it over a month ago because the original one did not have the option to disable the internal HDD which I needed for testing drive cloning software (probably not the most common reason for doing this). Today I upgraded the memory and your BIOS mod worked like a charm auto detecting the higher (and not officially supported) speed of 1600. The speed shows as ~800 in CPU-Z as well and my WEI memory rating increased by 0.2. If you find yourself in Canada's capital I owe you a beverage of your choice!

:thumbsup:




Relevant system specs:

CPU: i7 2670QM

added to the list

glad you liked it

well, I doubt I get into canada, or at least in a while, but I will take your offer

thanks ; )

 

Hi capitankasar, i have been trying to download the BIOS recovery file but for some reason every time i go to the link it drops to server not found. I was wondering if there is another location that i could download it from? Cheers in advance.

Alex

 

Are there any settings in the advanced BIOS that could affect the hibernation capabilities of the laptop? I recently reformatted and upgraded to Windows 7 Pro which was how I found myself here trying to fix crash issues that occurred even after the reinstall.
However, I found out today that for some reason when I hit hibernate, the computer just locks instead. Any reason why using a modded bios would cause this? Perhaps a setting was changed that I didn't notice?

 

It's not problem with bios. Win7/8 sometimes locks with no hibernate option - I had this 2 times (like you - hibernate and immediately go to lock state) - seems that it's problem with hibernation file. Do you have multiboot with other Windows?
Or if you want to be sure that it's not bios related... just reset bios settings to default (don't need to reflash bios).

 

@pogster88

it works fine for me, try this direct link without the ads
l502x_bios_recovery_by_capitankasar.rar

@NovaTornado

mmm, I dont have any of them in mind now, however, I remember I had blue screens of the death while trying to hibernate or resume from hibernation with the stock bios and stock dell installation.

problems went away updating the bios and reinstalling the OS.

 

I'll try disabling/renabling hibernation. Maybe something derped while doing that the first time. Yea, I didn't think it was the BIOS but checking to be sure. I looked through the stuff and didn't see much related.

Edit: Ended up being my wireless mouse would send little signals of movement from like table vibrations which would wake up the computer before hibernation fully closed it... xD

 

Hi Captain,

I was experiencing lock ups so decided to update to Dell’s A12 bios. I’m not sure which version I previously had before the update, but after the update it seems like my l502x has become a brick. I tried your bios recovery CD, but the machine just sits there with a blank screen and the CD drive flashes only for about 5secs then no activity. Please help. Thank you in advance.

 

@asianstyle

hi

well, the system flash have many stuff inside like descriptor, ME region and BIOS region.

my recovery CDrom recover the bad bios region flash.

however, it doesnt recover from deeper bricks.

if you tried my recovery method and you made sure you didnt skiped any step, sadly, the only way to recover you laptop is hardware flashing (more info at the first topic), it require electronic knowledge and some tools anyway ):

 

Turns out it was my bad, I'm currently in china and didn't realize mediafire was blocked here. Any chance you have it on another file hosting site? I must have downloaded the other files from MIRROR by ximinez. If not then thanks anyway

 

where Patch SpeedStep For OSX

 

@pogster88

mmm, I dont have any other mirror, and since the file is big and my connection is way slow, I cant upload it, maybe someone else can upload it to other site like mega.


meanwhile you can try downloading the file through a proxy, it may bypass your country protections.

@ahmedshiko

you should be able to find it at the A12 v4 and v5 versions of the advanced modded bioses of the first post ^^

 

@pogster88
Heres some mirror links that I hope aren't blocked.

@capitankasar

problem patch SpeedStep in Boot Mountain Lion 10.8


Kernel Panic

Please Help

 

I had Bios A12 installed with the default voltages for the GT540M.

After using EasyBCD to change boot entries, I cannot get past the POST screen. I had Windows 7 installed with UEFI mode.

I removed all of the options besides the Windows 7 boot entry, even those such as USB, CDROM, setup.. etc. I now realize that was an awful idea. I cannot boot into anything. Bios setup, boot options, nothing. I've tried the recovery method listed and several others on the web.

But no matter what, CD in the Drive or not, The POST Dell screen comes up and the F2 for setup and F12 for boot options is there and the bar loads but that's all the farther it goes.

Any help would be great

Emal replies would be preferred for reply mitchfultz at gmail

Thanks

 

Cheers mate, the links work fine.

@capitankasar

I burned the iso onto a dvd, but every time start the pc using the END button method, the fans ramp up to full and the on button starts blinking and the keybaord lights up. But the screen stays black, tried it without a disk and the same thing happens. Any ideas? : /

 

@NovaTornado

huge thanks, I will add them to the first post and will credit you

however i have a problem with the rapidshare one, I get a "Download permission denied by uploader. (0b67c2f5)" error

@ahmedshiko

mmm, didnt tested the bioses on any other system than windows, so I cant help you much in there


@mitchfultz

install windows on uefi mode has been reported by many users as problematic.


mmm , so as I can see, you seems unable to boot anything even with a boot cd, right?

try loading bios default settings, and save, then go to the boot settings, and ensure the cdrom is over the hdd, you can also try with the boot menu.

@pogster88

does the power button still blinking? or it stops?

with the cdrom in , it should stop blinking while without cdrom it should keep blinking.

the blinking power button basically means the machine is looking for the recovery capsule.

you can try also coping the BIOS.cap file from the cdrom to the root of a usb stick, and then plug it at the usb port from the right, (the usb/esata combo port)

 

Correct, I am unable to boot into anything. The Dell splash screen will come up, and the options for setup and boot options will appear in the lower right corner, but once I press the corresponding key, it locks up and remains stuck on the splash screen.

This prevents me from getting into the Bios settings or boot options. I am burning another copy of the recovery disc again, but it did not work the first time I tried it.

Any ideas? I am able to format my hardrive if needed. I have information I need backed up.

Thanks.

 

To be more clear, following your directions with the CD recovery feature, the splash screen will come up and I hit F12 repeatedly. The F12 Boot options text in the lower right will highlight, but then the machine goes no further. The CD drive stops spinning, the fans stop, and I am left with The Dell splash screen, full blue bar fully loaded.

 

@mitchfultz

by using the recovery method , your bios settings , will restore to default, you dont even need to flash it, just boot the recovery capsule from the cdrom, then turn off the machine and go to the onboard bios by pressing F2.

that will restore bios defaults for sure and will get your problem fixed.

 

@capitankasar I think I fixed the rapidshare link. Didn't realize I had to enable public downloads. Here is the link again that should work now: http://rapidshare.com/files/2867571646/l502x_bios_recovery_by_capitankasar.rar

Edit: Also, I can't guarantee these links will stay alive. I think rapidshare free accounts delete files after noone uses them for 90 days. Mega seems to not have a time limitation, so that'll stay alive at least (or till the company shuts down).

 

@NovaTornado

ok, thanks, I will edit the first post now, like I said, thank you very much!

 

My computer must not be loading the recovery capsule. The light on the disk drive will blink and so will the power light. The disc drive light then stops blinking and then after a few more seconds (3-5) the power light stops blinking and the splash screen comes up. At this point F2 and F12 still do not work so I then turn the machine off and power it on normally and press F2 to access setup. The splash screen comes up and F2 Setup highlights and I am stuck at the POST splash screen again..

 

@mitchfultz
if the splash screen appears at the recovery mode (end key + power cord plug in) and then the splash screen appears, then it definitly loads the capsule.

because if no capsule is found, the screen still black.

aparently, that should reset the settings to default.

if that still not working, try check that they keyboard works and it is plugged, try plugging a external usb keyboard too.

else, well, not sure what it could be the issue

 

Hi everyone! I have the Dell XPS L502x. The laptop was fast everytime i restart or hibernate it. But after about an hour, the laptop become slow, that opening a 100kbps PDF file takes ~10s. Does installing this BIOS will fix this problem? or is it something wrong with my computer? thank you so much.

 

@chocoseries

hi, installing modded BIOS have many beneficts over the stock one, however, your issue doesnt seems BIOS related, I suggest to defrag the disk and check your power options, also , if the laptop run in battery mode it may enter in safe mode after a while.

checking the apps running in the background and checking the ram and proccesor load would be interesting too.

 

I've done all of that before, but it doesn't change anything. Btw I've found the solution! Turn off intel speedstep on BIOS, and voila. Its done.

 

I was wrong, it still slows down after a 1-3 hour usage. Only shutdowns fixed that, which is disturbing.

 

try switch off dinamic FSB under the proccesor settings in order to see about any differences

 

How's it going? I was gaming it up and I actually realized that the volt mod beyond 1.000v actually works since 1.050v is hotter than 1.000v by quite a lot.

Anyway, any chance u could throw together a 1.010v bios for me please kind sir? lol 1.000v isn't enough for crysis 3 at 800mhz... need 1.010v to get stable and have reasonable temps. I think you made me a 1.025v one I'll have to find it if u did...

 

@chris89

mmm, not sure but I think you had a different laptop from the one being modded at this topic (the L502X)

I think your laptop was the K53SVAS but not sure

I found three modded bioses made for that laptop
one is 1.05v and the other one is 1.08v, the other one I dont remember what mods I did.
K53SVAS_(1.05V).rar
K53SVAS_(1.08v).rar
K53SVAS_320_mod.zip

since I cant remember now how I modded that specific laptop model BIOS, try the 1.08v and check if the OC improves, if it does, I will try to remember how I did, and then I will try the 1.10volts version

 

@capitankasar

Thanks yeah it does seem to improve stability in terms of minutes it stays running longer just too hot at anything around 1.050v well at least I know the 1.050v one runs really hot. I think 1.010v and 1.025v may be ideal to attain best stability.

Anyway maybe the bottom one u posted is 1.025v so I'll test and see. EVGA Precision detects the correct voltage but AIDA64 shows 1.000v so I know the volt mod is in fact working because it gets hotter.

Thanks

 

Okay so I flashed the 1.050v one and all seems well. All I need now is a memory voltage increase so I can boost the ram to 1066mhz or something from 900Mhz. Since obviously the bottleneck is the ram being only 1GB dedicated and only 128bit, if it was 256bit it would be out standing and if it was 2gb with 256bit that would be insane! I just can't run past 1280x720 on high end games like crysis 3 without a solid fps drop to below the 20s. Then I set to 1280x720 and it's 60fps solid...

My temps are all over the place one minute my temps are too high on low voltage and now at 1.050v they seem to run cooler than 1.000v. Since the gpu hit 77C last night and crashed. Now I ran the 1.050v one and I was at 65C and no crash... I run my cpu locked down in turbo boost 3Ghz when gaming and it really makes a difference in fps on crysis 3.

 

@chris89

well, if it run cooler on 1050v than on 1V, then it may be running on a lower voltage.

my laptop runs perfect on 0.85v, higher voltages make it crash, and lower seems to crash it too, not sure if it detects invalid voltages and set it to some kind of default voltage.

and as for memory voltage, I didnt found anything related yet, even on a desktop GPU, the only way I had to increase memory voltage was hardware mods to increase it.

maybe you can hardware mod the GPU to increase the voltage and archive higher OC

 

@capitankasar

Yeah im not entirely sure but evga precision sees the correct 1.080v and my system seems more stable in crysis 3 but maybe crysis 3 is buggy I get an error like DXGI_device_removed which is odd. So I boosted to 1.050v and still got the error then boosted to 1.080v and it hasn't occured yet and my temps are only 65C at 800Mhz and 1.080V so i don't know. I think I'll stick with 1.080v and see how it goes ill update later.

 

@ capitankasar

Maybe you could batch together an insanity 1.100v and a 1.125v mod lol!! If you don't wanna make 2 or even one no worries bro. If you are willing to make one for me maybe let's just push for 1.125v since 20mv isn't much from 1.080v, I feel 45mv should be sufficient. I wanna try 850mhz since 800mhz is stable at 1.080v so why not try 850mhz...?

Thanks Bro

 

@chris89

srry for late answer, I am not very active at the bios modding right now since I have less time now.

also , for your particular bios model I didnt remember how I made it until now.

here it is:

be carefull specially with the 1.125v one, if your GPU is not properly cooled, it may be damaged.

K53SVAS_(1.10v).rar
K53SVAS_(1.25v).rar

 

Thanks man! I appreciate it a lot! By the way when running at 1.080v I hit 67C max on the gpu after 30 minutes of game play. Then it crashes, so it's incredibly unusual for it not running hot enough to crash. I can run through 3dmark06 and quite a few other games for hours and only Crysis 3 seems to crash... I hate this.

I'm beginning to think it's just an issue with the game since it crashes but I don't think its the stability but rather the games glitch.

It even says DXGI_DEVICE_REMOVED after say 30 minutes every time. I'll try turning down the overclock but I'm not so sure if it will do anything. Will just need to do some testing first.

 

well, lets hope you get some improvement with the modded bioses

however, games like dead space series are a pain for overclock, I had to disable totally the overclock for that games, it crashed the whole computer with minimal OCs while other games ran fine with higher OC for hours, many games do not like OC very much

 

This may sounds dumb, but how do you actually turn it off?

 

@chocoseries

it is at the same sub menu as disable hyper threading is (proccesor configuration sub menu at the advanced settings tab)

the option to be disabled is dynamic FSB switching

 

How do I disable c1e in the modded BIOS?

 

if that bios option isnt at the unlocked bios submenus then I think it isnt at all.

I noticed there are some other hidden menus, at the advanced setup modules, but they cant be unlocked using the methods we used to unlock previous ones.

they need further Intel ME hacking in order to enable them i think

 

I just flashed the A12 .83/ .85 BIOS and in a game at the point where it would normally freeze it would just sort of hang for a second. That alone was more progress than I ever made by contacting Dell. After a very slight underclock on my gt 540m, I can confirm that I am no longer experiencing any crashes in games. I also can report minimal performance loss. Thanks for all your hard work providing these BIOSes!!

 

Sup bro? Thanks for all your help man. Can you make me a 1.35v and 1.45v one? I can't get stable at 800Mhz in bioshock infinite and crysis 3.... 775Mhz seems fairly stable but fps is too low. I need 800mhz since my friend has a GT 650M which runs at 750Mhz and boosts to 850Mhz automatically. I need my GT 540M to at least compare...

 

Hi, Ive been reading this thread and managed to install one of your latests Bios. My problem is kind of rare I think. What happens is the following (all of this previous to flashing your bios and also after).

Everytime I start a new game (simcity, tomb raider for example) it runs perfectly fine for a couple of minutes. After that the game starts to stutter and the FPS go down to almost 3 or 5. Also the GPU usage gets low to 20 or 30%. So basically it is as if the game suddenly stops using the full force of the GPU and lowers it to that percentage, making the game go very slow.

This happens on every setting and in various games. I am using the lates beta drivers for nvidia. My laptop is a Dell L502X with i7 processor and 8gigs of ram, intel hd3000 graphics with nvidia Gt525m 1gb.

Can you give me some insight on what is happening? I guess you are one of the only persons in the world that could have some idea of what is wrong.

I took a screenshot of what happens in my GPU, notice the sudden drop of usage, that is while the game is still running. Are my temps ok? should I overclock a little? Which driver do you suggest?

Thanks a lot for your hard work!.
