L502X modded bioses download (GPU voltages and more!)

Or just download latest BIOS from Dell site and run exe file...

 

Just flashed the above. Working fine so far. Did notice that a bunch of USB entries were disabled in the advanced menu, and I had to enable them to get my keyboard to work in GRUB.

 

Is it possible to go below 0.83v on the 525M for the 2D profile?

 

is posible to edit the values to lower, but not sure if the card will phisically get that voltage or monitoring software will Lie.

 

Hello, I have Acer Aspire 5750g, can I use Dell A11 bios? Because I don't know how to undervolt the GF gt 540m other way...

 

if you have naother laptop, then you must mod your BIOS, because if you flash another laptop bios, your laptop will not turn on anymore ^^

 

Acer Aspire 5750g does not have modded BIOS to control gpu voltages.... :/

 

[Unlocked] Acer Aspire 5750G

as for the bios voltages, it needs to be edited manually, there are no software control as far I know, it need to be hardedited in bios while modding it

 

I see, but there is no voltage control modded BIOS for acers 5750g...

 

yep, there arent, you need to mod the video bios file and set the voltage manually, like we do with the L502X

the video bios file is 64 kb

 

Can you give me please some advice how to do that? I'd really appreciate it.

 

mmm, it is a little tricky and difficult, I can tell u how, but I think it may be faster that u provide me the bios version u want to mod (original or already unlocked one) and then you tell me the voltages for 2D and 3D and I can try mod it.

 

I have 1.21 original and I want 0.83V(2D) and 0.85V(3D), thanks alot!

 

you forgot to link the bios file you want to mod ^^

 

Ah...well, so I upgraded to unlocked version of 1.21, guess It'll be more easier to mod.

ok, need a last thing, your BIOS have several VBIOS inside

I need you tell me what video bios version are you using

I found 4 video bios versions inside your BIOS

70.08.6C.00.03
70.08.3C.00.22
70.08.3C.00.19
70.08.72.00.A8

to know what video BIOS are you using, you need software like GPU-Z



if you can post a screen shot like this from GPU-z I will proably able to mod your BIOS

 

Here it is. Thanks again

 

@kodlosek

done.

give it a try

P5WE0121_mod.rar

this is only for the acers 5750g

 

Thanks man! You're an animal, it is working just great, 10-15°C cooler even with OC...

 

glad you liked it

 

One last think I want to ask, tho GF 540m has not adjustable fan control, is there a way how to adjust it to higher speeds in higher usage?

 

mmm, not sure.

try to check the modded bios settings, since you told me it already had unlocked menus, maybe there is something there.

check the acer control panel if there is any software installed and give also a try to the windows power plan.
also at the nvidia control panel set the card at max performance setting.

also if you want cooler temps, you can try hardware mods, well, your laptop is probably different from the ones of this topic, but you can try take it appart and repaste the GPU and CPU, also look for dust filters or any other kind of thing blocking or limiting the airflow and remove it.

that plus the lowered voltages made my L502X machine run awesome fast plus super cooler temps.

 

well hello its me again ^^ so the last solution i tried from the dell forum didn't pay out as intended, but i was to angry to even write in the forum at the time ^^ so now i am giving you a update: i temporarily using:

As i am realy comited to fix this problem i would like to redo or retry everything, so i can fix this crashing peace of
****
*cough* sorry i am realy angry with dell, but that aside, just advise me what i could try next or what you need to know or anything else ((

 

I still have the same questions. How did you apply the thermal paste? Did you lift the heatsink after applying it? What are your max. temperatures, you still didn't clarify it.

 

actualy i did xD I told you that i applyed the paste with much care and no i did not lift it afterwards. i dont know the temperatues as i do not know how to handle the program to save logs of temp as the pc crashes

edit: figured it out. Cant get the pc to crash atm

 

You're confusing me. You're saying that you did lift the heatsink and you're also saying that that you are also saying that you applied it with care. And you still didn't tell how did you apply the thermal paste????? Did you spread it?

See these videos. It'll tell you how thermal paste spreads:

https://www.youtube.com/watch?v=EyXLu1Ms-q4
https://www.youtube.com/watch?v=ffK7L0Qj13Q

 

YES I Spread it !!!!! as i told you in a comment before i applyed it as discribed in the guide!!!!!!!!! i DIDNT lift the heatsink AFTERWARDS! clear now ? just to be crystal clear: I did EVERYTHING as shown in the guide posted by kasar! down to the ingredients! I'll try to crash my pc now by taking out the underclock and i actualy also put my game on ultra ... the pc didnt crash yet -.-

 

You shouldn't spread the thermal paste...it creates air bubbles -_-

 

then i didnt xD a gave my friend the guide and he is a little more experiencend with this stuff then i am , he actualy did it , so can we move on.. pleeeeeeeeease ;>

so .. the pc just doenst wana crash x_X

 

Apparently only temperatures can tell the truth.

 

k so finaly it crashed now i got a data with many stuff in it but i dont think these are temperatuires .. anyways:
View attachment HWMonitor.txt
guess i am kind of stupid

 

Its showing your GPU 65C but doesn't tell much. Is it your idle temperature? What were you doing at that time on your laptop?

PS: Use HWMonitor Pro to record your temperatures while playing the game.

 

tryed it but it wont save the logs when it crashes dont know which temp is idle atm and i played World of Warcraft which seams to be the only game with call of duty 4 where crashes acure... Bf3 runs smoothly aswell as deadspace 3

So i was waiting for your reply i tested something..
i overclocked my gpu a little , which seams to delay the crash by ALOT! dont know if this helps you either.

 

I am currently using to 0.83/0.85V. This mod had drastically decrease the amount of crashes in games, but it would still happen sometimes after many games of League of Legends. My current clock speed is 672/900/1344. Should I lower the gpu clock speed to maybe like 660 so that it will completely go away? if so, how can I do it? I am not sure what software I should use for changing the clock speed. Thanks

 

@Bergal

do you mean Underclock?
because it is very weird it crash lower by Overclocking the card, wich is basically pushing the card even more ^^


@jingtai1993

exactly

if the mod doesnt fix the crash issue fully, you will have also to underclock the gpu a little, try with 660 mhz, the issue should be totally fixed like that way, else try 650 mhz

 

yup i know its weard :O
well anyways wont read much into it. i underclocked now and wont change it course i cant seam to figure out a solution

 

Quick question: Does the Intel ME update on the first post still work? Seems to create an error.log which says "This program cannot be run on the current platform."
I'm currently on the stock ME from Dell.
However, using advanced custom 540m A12 with 2D PROFILE: 0.83v 3D PROFILE: 0.92v ( Ctr + F the MD5: 4A4215FB25C4FCEDD6F64037B77792B3 ) which works great

 

@Bergal

yeah,sadly, underclocking seems the only solution for your case, let us to know if you still experiencing crashes even with underclocking

@NovaTornado

yes, the ME update still working

that error is weird, are you running windows 7 x64? or older/newer OS?

that update is tested under windows7 x64 only

glad the modded bios works great for you

added to the first post ^^

 

Running Windows 7 Pro x64, and I just installed it about 2 days ago. Still doesn't work after a reboot. Running this on the admin account to be sure, but no go. :\

 

not sure then, all people seemed able to install the ME update without issues.

try installing the ME drivers and try again

http://downloadcenter.intel.com/Detail_Desc.aspx?lang=eng&DwnldID=20078

 

Installing the ME drivers again fixed the issue. Guess I was using a different version before.

 

Kasar, you are dabuti

I should have returned to this thread earlier. Yesterday and today i read all what i missed.

In the meantime so much was made possible to our machine. Even some basic fan control with HWiNFO64, hopefully it can get even better, including temperature ranges for turning the fan on and off. Unfortunately i get stuttering depending on the time value i put into the "Respin period" field. Unfortunately it seems that it needs to be checked for the fan control to work.

Another issue i have is the high "CPU Package Power". A long time ago i asked about this in the Throttlestop thread but i was told it was normal not getting below 5.5W with an i7-2670QM(at 800MHz). But now i have seen NeoMesal in the owners lounge thread posting a screenshot showing like 3.5W for his i7-2630QM which is basically the same cpu, showing temp less than 40°C: http://forum.notebookreview.com/del...2-dell-xps-15-r2-l502x-owners-lounge-400.html (at the bottom)
I wonder how he does it. This 2W in idle make a huge difference in temperature and fan behaviour.

Well, thanks again Kasar. Now i will flash the modded A12 0.83/0.85. Do you recommend flashing the Intel ME 7.1.52.1176 or is it riskier than flashing the bios? If i understood it correctly for overclocking the cpu(grats!) you wrote into protected areas of the Winbond flash? Maybe you can sell these modified chips to interested users(like me Another question: How did you solder the bios-socket to the mainboard? From the backside? I really would like to do it, but i dont dare.

Another remark: This threat should qualify you as a high level technical guy independent of any formal qualification. With your bright mind you could do such stuff in a lot of areas.

All my best wishes to you!

 

@gilipollas

thanks!

that BIOS version should be fine , make sure you have the v5 version of the mod to archive the best results.

as for the Intel ME 7.1.52.1176 update, it isnt risky to flash it, it is well tested, anyway ensure the laptop have the battery fully charged , that it is plugged to a wall, and that you dont have other apps opened (usual secure flashing procedure )

the ME update doesnt have nothing to do with overclocking, it is an update over the stock ME version in order to fix some posible bugs and maybe add some other features like any other update.



however, I relased a ME patch for the Intel ME 7.1.52.1176 update, the tricky part is that it need an unlocked descriptor settings.
it require to change data on a protected area of the windbond flash like you said.
and the only way to do that for the L502X, is desolder BIOS chip, create a DUMP from the chip, and hex edit the image.

changed needed are easy, just look for this string

00 00 0B 0A 00 00 0D 0C 18 01 08

and change it to

00 00 FF FF 00 00 FF FF 18 01 08

then flash the modded image to the chip, and resolder the chip.

the tricky part is the hardware modding needed to access the BIOS chip

more info about the hardware part is here:

http://forum.notebookreview.com/del...ed-bioses-download-gpu-voltages-more-129.html


as for how I soldered the sockets, first I desoldered the bios chip manually using a cheap soldering iron with a decent thing head (if the head isnt thin enough, you will need to rasp it or replace it with the smallest posible size)

I used a small trick to desolder the chip

I used a a small sewing pin to leverage to lift each leg meanwhile you apply heat with the soldering iron (dont lift the leg too much or it will break, and dont apply heat during a lot of time, or the chip will get damaged like the first one I had after several solderings and desolderings)

as for the socket soldering is the same, but you dont need the sewing pin at all.

you will need to take appart the whole laptop if you want to be confortable while soldering it, you need to have the motherboard away from any plastic case.

then while asembly the unit, you may need to cut a small square from the top cover under the palmrest (dont worry, then the unit is completly asemblied it isnt visible, but it is needed to fit the socket, it also make easier to remove the chip by just removing the palmrest in order to access the socket, because once the socket is properly soldered, take appart the whole unit isnt needed anymore.

its very important you save your first chip backup in a safe place, because if things go wrong, you will need it to restore your laptop.

well, as for the programmer, you can build a cheap/easy one like the one I did (it is the easiest one I found) or you can buy some premade programmers, but cost will be also higher.

If you have in mind replicate this mod, please, keep me updated, I am very interested to see if someone else can replicate this mod too on this machine, because as far I know my L502X is the only one with overclock unlocked.

keep me updated about your progress, and if you need help, during the process feel free to ask


and thank you so much for your comments!

and well, if u want to know, I still looking for a job

 

Does the memory frequency option in the BIOS work? Can I change it from 1333MHz to 1600MHz on my i7 2630QM?

 

@smsmasters

yes, it works, worked for many people with compatible RAM modules.


not sure if it will works with your proccesor anyway, because on this site it report just 1066/1333 speeds

@all

adding right now aditional info about how to unlock descriptor and Overclock the L502X at the first post, however, hardware modding is required, that is why it is labeled more advanced mods.

Both is working fine.

I would really love to have the mod but i dont dare doing it Also i need the laptop and flashing bios and ME is the highest risk i would take right now.

I remember you wrote somewhere that without changing the descriptor it is possible to set the fsb to values between 95 and 100MHz. I dont remember where i read it. Is it true? And which program is necesary? Or am i confusing something?

 

@gilipollas

added to the first post ^^

I also modified the first post with aditional info to be able to overclock the machine and unlock the descriptor.

let me know if you want to give a try to the mod later

and as for change the BCLK from 95 - 100mhz (underclocking only)
I used
XTU-Setup 3.1.201.5.msi

the same app wich let to Overclock with the patched ME for overclocking I made.

 

lol, actually i did lower the package power by about one Watt by reversing the tweak in the link below, hopefully doing this is not stupid.
How To Improve SSD performance on Intel Series 4, 5 and 965 chipsets (Stamatisx Tweak)

XTU shows me a slider to change the bclk between 99.5MHz(not 95) and 100MHz, but when clicking 'apply' it switches back to 100MHz. So i guess editing the descriptor is also needed for underclocking?

 

Anybody knows which parts are CRU (Customer Removable Unit) so we can dismount them without voiding the warranty? I can't find that info on Dell site (only CRU definition)... Probably HDD, RAM... But question is: PCI (WiFi etc.) too?

 

@gilipollas

mmm, it worked fine for me even without modding the ME or descriptor.
are you sure , it doesnt works for you?

try having CPU-Z running at the desktop to ensure it doesnt changes.

however, that isnt very usual.

for me, after editing the ME region, I removed the limits and it apply changes without issues.

@agalin

probably , ram and minipci cards (the one removables from the expansion door.), hdd and optical drive maybe too, but I have no idea at all, my warranty ... well, it doesnt exist anymore xD
