L502X modded bioses download (GPU voltages and more!)

my score was 7500 at stock. But your temps definitely seem high across the board....

 

As a fellow Starcraft 2 player. I can tell you that starcraft 2 is the best application for testing your overclocks. Starcraft 2 will crash with the slightest instability with your GPU. I would flash the .98v (stock) instead of the .85v you have now. Next you will have to reduce core clock until starcraft 2 stops crashing. Before my motherboard got replaced, I lowered my 540m's clocks to 600Mhz for it to stop crashing. Keep memory at 900 Mhz.

 

hi capitankasar just wanted to know if you knew that the evga precision has a voltage tuner built in that lets you also increase your voltage for our geforce cards was even letting me select 1.0v

 

is starcraft 2 a direct x 9 game i personally think our cards have problems handling direct x 9 as any other directx 10 or 11 game can run at alot higher clocks without crashing, for example skyrim at my current clock of 830 will crash inside 10-15 minutes wereas playing rage which is direct x 11 plays on the exact same clock speed for hours without a single crash

 

nope, I didnt knew.
do it also let you select 1v for the 525m?
I wonder if this is the end of the modded voltage bioses for this laptop ^^

well, I got the app today, but I found the same problem i found with the new msi afterburner betas, the app is freezing at the interface, very slow.

thats why I'm using the msi afterburner 2.10 version, and not the new betas wich get the freezing issues.


also ticked at the "adjust voltage" button at the evga precission, but nothing popup or let me change the voltage, I just noticed the proccesor ussage get crazy, but nothing else, I had to kill the app by task manager.

that is may related I am already using a modded bios? 0.83v/0.83v

now I'm back to msi afterburner 2.10

 

Was your experience of the crash similar to what has been described? Meaning, game freezes, can't end process, and ultimately have to hard reset? Also, was this issue always present with your laptop?

 

hi capitankasar i use the v2.1.2 of evga precision cas the newest 1 is slow for me aswell, but there is an extra program in the evga program folder u have to click into the bundles folder and then double click on the evtune program and load it at the bottom it allows u to select the graphics card u want to change the voltage for, sadly it is all greyed out for the intel integrated card but for the gt525m card all the 1v options and above r there

 

I just tried running the GT540M@750/1500/[email protected]. (not 1.85v, lol)

3dmark2006 results(1280x1024):
3DMark Score 9322 3DMarks
SM2.0 Score 3746
HDR/SM3.0 Score 3339
CPU Score 5312

Max Temps during 3dMark2006:
GPU 71°C
CPU 89°C

3Dmark2006 run with no crashes.

Thanks again for this nice bios.

 

This weekend I've been playing the Diablo III Beta with 785/1570/1001. CPU temp peaked at 87C.
I wonder how low it will go with copper shim, repaste and removed dust filter

 

Just out of curiosity, why people's preference for using 3Dmark06? I thought that the '11 version would be... "better" being newer. (which is the one I use)

EDIT: Generally getting a constant P1300 3D Marks for '11.

I would expect those temps to go down about 10C. Be interesting if the copper shim has any noticable difference.

 

Double post

ditto

 

@Matix5:
Maybe tradition. Maybe because people dont want to install too much big benchmark programs(like me).

 

Someone out there has any idea what this XPS 15 PROC MOD is?

Sorry if this has been asked already, but do people find that the 3D profile at 0.85V stable when you OC up to 800/1600?

Normally I leave my speeds at stock. Sometimes I'll bump them up to 740/1400 or 800/1600 depending on whether the game needs the extra oomph or not. I'd like to use the undervolting BIOS (the one with 2D PROFILE: 0.83v, 3D PROFILE: 0.85v) to keep temperatures down a little bit, but am not sure how stable they are.

Any feedback is much appreciated

Thanks!

 

@daver160

max stable overclock is different for all people.

all you can do is try and let us to know how it works for you ^_^

 

Install it and let us know!

 

I flashed the BIOS that has the 0.85V 3D profile, and find that every now and then the voltage jumps up to 1.0V for a brief period of time (e.g. 1-10 seconds) before settling back down to 0.85V.

I'm not too familiar with how voltages work, but is this normal?

 

Strange, if I recall somebody else had a similar issue...

Reflash the BIOS and reinstall Nvidia drivers. Also see if it happens with another revision (eg A09)

 

OK I'll try that when I'm home tonight.

I didn't know if that spike to 1V was a "normal" thing to happen. The spike, when it happens, is always consistent though. It happens whenever the GPU transitions from a low load to a high load.

For example, in Tribes Ascend there is little GPU activity in the main menu. WHen I load up a session and enter a round, the GPU activity obviously jumps to 100%. It is the moment that the GPU goes into 100% activity that the voltage spikes to 1V for about 5+ seconds, and then drops down to 0.85V for the rest of the time. Then if I'm at a loading screen, the voltage drops back down to 0.83 or something, and the spike repeats when the round begins.

 

It shouldn't happen. Also, what program is reporting the 1V?

 

nVidia Inspector, reading out the value in the Voltage field.

I had a game running 1360x768 windowed for a while so I could check the value.

 

That's the same "problem" I mentioned before...I haven't checked in awhile, but I imagine it is still doing that. I have flashed my bios several times, but it still occurs. I should check with stock bios, but I'm too lazy. I don't foresee any problems.

 

Yeah, if it isn't being a problem, then probably nothing to worry about.

 

Hello again,
I just finished flashing the other A10 BIOS with the below details:
MD5 checksum: 483191FDA9FFBCACCEECC92455D11184
BIOS version used: A10
2D PROFILE: 0.83v
3D PROFILE: 0.83v
(used stock GPU clocks just to keep stability while testing).

I found the same thing where the GPU voltage temporarily jumps up to 1V for a few seconds before going down to the undervolted voltage of 0.83V. This time I was playing Ghost Recon Online beta.

I wonder if this is just normal behaviour at this point. I didn't crash at any point, nor did I notice any kind of problem with the GPU. It might just be that the GPU draws a little bit of full power at the start to kind of "get things going" to so speak. Once it comes down from 1V, I notice that it doesn't go back up (until the GPU returns to idle and needs power again).

I'll just return to the modded A10 with the 0.83/0.85 voltages. It seemed to work well enough for me.

Thanks!

 

Yes, that 1V burst might be preventing problems when starting back up.

I can run games fine at 800 core, but if I minimise and restore a game it will crash under the "stress". That's when a 1V boost would be nice

Interesting that it only occurs on some systems

 

I guess I am fortunate enough to not suffer from crashes. I am able to run all the games I've tried at 800/1600/900 (Ghost Recon online, Tribes Ascend, Burnout Paradise), and have had no crashes.

 

Try 800/1600/1000; that seems to be a and good overclock. If it runs that well with the undervolt, you have a very good card (I wouldn't go any higher with an undervolt)

Cheers

 

I've done that already. I use the MSI Afterburner Android app to set those speeds, and I'm just that lazy to not set the memory speed... you'd think that setting up the remote server takes more work than to drag the slider and select "apply" lol

 

So I downloaded one of the Bios's for the GT540m. I got to the part where is asked, "do you want to flash the modded bios?" to which I of course typed y and hit enter. After that, I get this message that reads, "'Winflash' is not recognized as an internal or external command, operable program or batch file." It then tells me to press any key to continue twice, then closes.

Does anyone know what is going on with me?

 

did you extracted all the files before run the batch file?
are you sure all the required files are in the folder?

if you still having problems try run winflash.exe with following parameters:

Code:

WinFlash.exe /all /sa /sn /sd /sp /svs /sv /cvar BIOS1.WPH

you can do this by creating a shortcut to winflash and edit it.

or from a cmd window

you may need to specify absolute paths to winflash.exe and bios1.wph files

 

Yeah it was a silly error lol. Just didn't extract the files. Thanks for your help, captain. I just noticed you are also the same person who made the BIOS's. I've played for about an hour so far in a game that would normally freeze with that obnoxious metallic sound after 10 minutes on average. Many many thanks for the BIOS's.

 

thank you ^_^

glad you liked the mod

if you tell me the details of the bios you are using at the moment (bios version,GPU model and voltages) I can add you to the first post

 

I am using the GT540 BIOS, version A09, with 0.83v for 2d, and 0.85v for 3d. Unfortunately though, I'm starting to get the same problem again where the game freezes up with that metallic sound and I have to restart my computer with the power button.

The CPU and GPU aren't going much over 80 degrees Celsius, and I haven't gotten and game freezes while playing on the battery alone. I have only played with on the battery for two time periods equaling a total of about 2.5 hours, so I'm not 100% sure that my computer will always work on battery power. I'm starting to think that maybe it is just the motherboard.

 

@Hunter13040

added you the first post.

well, while some users reported the modded bioses fully fixed the issue, others also reported the modded bios only improved the situation , but didnt fully fixed it.

I would try the A10 modded bios, and the latest nvidia drivers, if that still not help, replace the mobo or underclock GPU core (reduce GPU core clock speed).

the default gt540m speed is arround 675 mhz, try lowering it to 650, if that not fix the problem try 640, 630, 620 .... until the crashes stop happening.

I admit I am starting to hate the gt540m, for some users it just seems a bad oced gt525m card wich need the clock be lowered again to work stable/fine, glad I did not wasted the money into the gt525m to gt540m "upgrade".

also not fully sure if the gt540m extra video memory is worth at all

 

Ok so an update on my problems. I send the computer to the depo and they changed the motherboard and fan and the problem actually got worse in games. I have had 100% crashes in Starcraft 2 and Black Ops that I tried but managed to play Dota2 for 5h straight without a crash. So I was on the phone and Dell made me do a factory reset and reinstall the newest drivers, but the problem still continues. The interesting part is that stress tests and 3dmark06 does not crash the computer but games do. The CPU and Motherboard still goes up to 95 degrees in stress tests or playing a game and streaming with xsplit.

The interesting part is that the computer does not crash if I unplug it from the wall and play on battery power. At least not the one time I tried after reading from another user that this must help.

I have an depo warranty and they wanted me to send the computer in for another motherboard replacement but I refused. I managed to talk to a manager and they will send a technician to my place to replace a second time the motherboard, fan and heat sink. I really pray that guy will be good and the problem will disappear. I will keep you guys updated.

 

not sure about why you posted the same post in at least 3 different topics.

well, it seems you are another of those gt540m users experiencing crashes,too bad the mobo switch didnt worked, however since you said the problem got even worse after the mobo replacement.

I also remember have been reading about users running the laptop on battery power seemed to avoid the crashes,not sure about why,I think it could be some kind of thottle but idk.

lets see if the second mobo replacement improve the situation, else you may need to try underclock the card if installing again the undervolted bios didnt fully fixed the problem.

 

Oh just wanted to share this sad experience with everybody possible

 

Howdy, running 525m here. Just want to say super thanks for the modded bioses. My l502x was not happy at all to play starcraft 2 before. Random graphics card lockups were incredibly common. With the .85v mod, crashes are history, and I can clock it to 740mhz too.

Thanks!

 

@Tazzle
glad to see another happy modded bios user

if you tell me what bios version you are using I will add you to the first post

 

I definitely noticed an improvement after flashing the A09 83, 85 BIOS. I was able to play CS: Source for an hour or two before it crashed, whereas I would only usually play it for 20 minutes tops before crashing.

I think lowering the voltage might be playing a big role, so I decided to flash the A10 83, 83 BIOS. I'm also about to underclock my GPU like you advised me to do, and I'll let the thread's silent observers know how that goes.

Here's my personal theory: The GT540m card is getting worn out some how from too much heat. Because it's getting worn out, smaller amounts of heat cause it crash. Therefore underclocking and undervolting the GT540m render a cooler card and make it less likely to crash. However, that still doesn't explain why running off of battery power renders no GPU crashes, so...

 

Battlefield 3 wasn't able to even start with the A10 0.83v for 2D, and 0.83v for 3D for the GT540m, so I flashed the A10 with 0.83v for 2D, and 0.85v for 3D. I also underclocked my GPU to 650 mhz, and so far, it is working just fine without any crashes.

If it helps anyone, I am also using a cooler master sf-19(cooling pad for laptop) and my GPU maxes around 70-72 degrees Celsius while I play Battlefield 3.

 

@hunter13040

well, 0.83v for 3d profile on 540m is well known to malfunction.

many users tried 0.83v 3d profile on their 540m without success, so it is normal.

however 0.85v on 3d profile for 540m works pretty good in most cases.

like you said, the 0.83v/0.85v bios should work fine instead.


since you finally got your system stable, if you are worried about performance, you can try to slowly increase your core again, to check what is your max stable core speed.

try 655 mhz, 660 mhz , 665 mhz ....

try 10 or 5 mhz increments until you find the max stable point with your current modded bios.

I will also add you to the A10 540m 0.83v/0.85v modded bios at the first post

 

No problemo brother, I am running the following bios.

 

@tazzle

done ^_^

Code:

this bios mod has been tested by Jovica666,kgh00007 and Tazzle.

 

@captainkasar

Well that' pretty neat that I'm one of the documented testers for your BIOS now. I imagined the testers to be like super high tech nerds(nerd with a positive connotation) and now I'm basically one of them.

 

@Hunter13040

hehehe

well, all people who contribute with some kind of feedback can be considered a tester for me

I supose most of them are normal people like you and me, people wich just wanted to fix their machine issues or improve the performance/reduce the heat ^_^

 

Just wanted to report back that I have flashed back to A10 with the 0.83/0.85V profiles, and that jump to 1V still happens. I guess that is not some sort of bug/glitch/problem, and that it's the GPU's way of preventing crashes or something (though I could be completely wrong).

I'm able to stably OC to 815/1700/1000, but i haven't tried pushing past that.

 

The technician was over today and changed motherboard, fan, heat sink and battery. Now the computer seems to be working and the temps are down. So seems like the problem was in the motherboard just like everybody else has had. Will try the modded BIOS versions later for some lower temps and OC.

 

Even for those who do not have problems, I highly recommend the modded BIOS for reductions in temps... or 1V higher OC'ing - your choice

 

Hi capitankasar, I have used your modded bios previously.
I just got my motherboard replaced and everything is working well so far.
It came with A09 bios installed, i have just upgraded it to (stock) A10. However, I have read that A10 causes CPU throttling and some people have rolled back to A09 due to that.
Can anyone advice if I should leave it as A10 or roll back to A09 bios?
