L502X modded bioses download (GPU voltages and more!)

Its i7-2630QM @2~2.9Ghz. Just called Dell and informed them about the lag issue. They'll send an engineer to replace the heat sink.

 

well quad cores, specially with turboboost enabled will generate more heat than two core proccesors like i3 or i5.


let us to know about if you got any improvement after the heatsink replacement

 

Yeah...

Sure..

 

What sort of overclocks are people getting on the 0.98V BIOS for the GT525M?

 

I have a request to all of the Dell XPS L502X owners out there. If you're reading this, I want you guys to post your CPUID Hardware Monitor Screenshots at normal usage (atleast half an hour), if possible mention the kind of task you were performing on the laptop. You can also post your gaming temperatures screens but do mention the game name. Awaiting screenshots. Thanks.

 

L502X i7 with just 3 Chrome tabs open and Spotify active.

 

^Your temps are pretty low. Would've been great if you expanded the whole window and then took the screenshot.

 

Sorry. Noticed that too late. This should be better.

 

firefox with several tabs (20 or more)
some background apps and listening some music with VLC

I just noticed about the battery wear, the dell software didnt said anything about it, but HWmonitor is very clear with it.

I think my mistake was to gamming with max performance configurations several times, that made the battery drain a lot of energy, making it being hot, and that isnt good for batteries.

I also noticed the system didnt wanted to charge battery sometimes after gamming on battery.

I noticed the battery temperature was the cause, I removed the battery with my hand and I noticed it was very very hot, after putting it into the fridge I proceded to charge it again and it was fine.

however the high temperatures helped to kill some battery life.

my advice is dont gamming on battery so much, especially without a cooling pad (I noticed battery was even more hot than the case itself near CPU and gpu)

 

@Phonemes

Thanks. Your system runs considerably cooler than mine. Do you use a cooling pad?

 

@capitankasar

Your battery wear is too much. Mine is 11%. I rarely used my laptop on battery (maybe 10-15 times in an year), so that helped me a lot in conserving my battery charge cycles. Yeah you should NEVER do gaming while on battery, I never did. I discharged my battery completely 3 or 4 times after 2-3 months gap just for the sake of initializing so that it doesn't show wrong 'time remaining' (how long can battery last).

Here are my temps with 3 tabs open (non flash) in Opera and music running in background on laptop speakers. Seems high, aren't they?

 

thx for the top alvester.

well, in case someone is interested, I managed to reduce a bit the battery wear level.

I managed to get 29% from 33%



what I did was discharge "completly" the battery (until system ran out of battery power and it stop working) and then charge it completly.

I went to power plan and disabled every low battery actions.

you cant set battery critical action to "do nothing" on windows 7 by the power plans window.

however there is a trick to do it.
I managed to do it by opening a cmd window and typing this

this will set critical level action to "do nothing" at your current power plan profile.
you can set it back to any other option by going into power plan advanced configuration.

 

This is called battery initializing.

 

thx ^_^

do you think if I initialize the battery 4 or 5 times like you did is worth of it?

I was thinking about give it a try in order to check if I can recover a little more %

 

^Well I initialized after every 2-3 months gap. If you do it regularly, it'll only decrease your battery charge cycle. So I think its not worth it.

 

My GT 525M (overlocked to GT 540M clocks) Temps during an hour of gaming:


PS: Using Modded BIOS 0.83v/0.83v A11

 

@alvester
well, not bad but it could be better, specially for the most undervolted bios for gt525m
in my case using that bios it rarelly went over 70º
I use now theA11 0.85v/0.85v since I noticed it is a little more stable with higher GPU clocks (running GPU core at 705 mhz at the moment )

 

I'm gonna switch to this mod too.

 

allright, I added you to the first post

this bios is a little more stable for me, but keep in mind it will generate a little more heat than the 0.83v one ^^

 

Funny thing is..even the unmodded BIOS generates the same temps for me as undervolted one. The only difference is that the unmodded one can't hold the higher clocks for long and hangs up. So switching to 0.85V won't be an issue for me.

 

lmao
do you have some kind of oven under your laptop?

one of the main advantages of the undervolted bios is the temps decreasing ^^

there must be something wrong with the thermal paster or something.

did you finally tried the hardware tweaks discussed here (repaste, remove dustfilter, and also cleaning the dust of the fan and heatsinks)

 

Is there a tutorial for removing the dust filter? So far I have not been able to find one.

Sent from my LG-P509

 

I'll try in future but not now. Don't wanna void my left warranty. Engineer will come tomorrow to replace the heatsink. Lets see how it goes after that. If that doesn't help, I'll get my whole mobo, proccy & GPU replaced.

 

well, if engenier is comming tomorrow, I suggest to temporally flash the original bios.

it would not be fun if for some reason he go into the bios and see all the modding things/title

 

LOL...Just did that and switched to default clocks too.

 

Well this is an interesting development. The engineer gave a visit today to replace the heatsink. He disassembled the laptop and blowed away all the accumulating dust in the laptop and then replaced the heatsink. After he was done with the assembly process. I switched on the laptop and checked the temps. They were down to 50C on CPU and 52C on GPU. I was really happy to see that. Then came the sad part. When the engineer left, I opened EVGA Precision and was SHOCKED. The temp of GPU was increasing like as if it was set on fire. It started from 55, then 63, 83, 95, 107 and LITERALLY 118!!!! within 5 secs and then my laptop just turned off without any warning. It refused to turn on until the GPU temps was in operating limit. Now every application (that uses GPU) I try to run whether be it game or designing software turns off my laptop within 5 secs.

I called DELL and now they'll replace my mobo, heatsink and thermal pad. Since GPU is soldered to mobo, it'll get replaced too.

 

mmm, what software did you used to monitorize the gpu temps before it started to raise up?

I mean you said it were to 50C and then after running EVGA precission it almost got on fire.

I would say the heatsink is badly or not connected at all to the GPU, but since you said you got 50C at the begining, IDK

 

HW Monitor. It accesses GPU like a heartbeat (you can tell that by looking at the GPU Activity Icon in the tray), so the temp didn't raise that much while on the other hand EVGA uses GPU continuously.

Maybe because HW monitor doesn't stress GPU that much.

 

well, hwmonitor doesnt OC the card as far I know, but MSI and EVGA software does ^^

anyway just raising the core without using the GPU doesnt produce a huge heat, for example, my GPU is on 700 mhz now, 0% ussage and it is on 57º

lets hope the motherboard replacement do something, else you will have to repaste by yourself, I doubt some tecknicians spent all care, time and effort on our machines like we do
that is why I wanted to fix the temp issues by myself even the system were on warranty by taking appart the lappy

 

Umm I know that..I was talking about temp monitoring. EVGA also monitors GPU temps but it continuously uses GPU while HW Monitor accesses GPU after every 1 sec gap. If I keep HW Monitor opened for 30 secs, the same issue occurs but 20-25 secs later than any GPU using application.

 

mmm, not sure but it definitly sounds like a bad phisical contact between GPU and heatsink,if before it was ok and now after just 20 secconds of ussage it runs on fire, there is something wrong with it.

well, I never called dell, so I dont know how they work on repairs, did you noticed if he used thermal paste? wich one?
idk

 

No I didn't but this time I'd..

 

Yes, I do actually. A Zalman ZM-NC3000U. I think temperutures on the CPU cores are some 3 degrees lower, 4 at the most.

 

I'm looking for a cooling pad for my L502X that can provide great cooling to my laptop. I've seen reviews of Cooler Master U2 an U3. U2 is smaller than U3 and has 2 adjustable fans while U3 has 3. Since I've 9 cell battery, I can't go for these two as I've already got the elevation by the protrudred battery. Moreover I've heard that U2 and U3 aren't comfortable for lap due to the design. There's Targus Chillmat but I don't know good is it for the L502X. I'm looking for a good cooling pad that doesn't have elevation and its fan placement is perfect for L502X vents. Any suggestions?

 

Hi all. I have a problem can you help me fix it. I have acer aspire 5742g laptop gpu 540M, and I want to up 540m GPU voltage to 1V. I do same like shown here: Acer aspire 5742g vga bios volt mod (hun) - YouTube .And it would seem that everything is managed:
.
But when I overclock 540m, voltage back to 0.98. In stocks clock voltage 1v when I OC 0.98v Whay?

And for you there change when modint gpu bios?

 

As someone who just yesterday made that switch...yes, it's worth it, do it.

 

Capitankasar, I tried your bios 0,83/0,85v, but I didn't save my old one and now my fan is spinning constantly on the quietest stage, yet annoying, and it consumes more power. What can be the reason for this and could you send me the original bios with factory settings as it was? PLS, if you can, send it, I can't stand this fan any more, not to speak about power consumption.
i5-2430m, gt540m 2 gb. Merci beaucoup
Thanks in advance!
By the way, when I open some application, concerning nvidia card like nvidia control panel or gpu-z, fan stops spinning...

 

@xpsuser1234555
if you want to go back to original bios, use the flash_original_bios.bat file wich came with the package, the procedure is the same and you will go back to original bios ^^

 

This is the problem - I tried it and the same again - more power and more voltage. Even in idle it's 0,98v. I'm desperate now. Do you have any suggestions what may it be - the strangest part - when i open some program about nvidia?
However, thanks for the help !

 

well, if you flashed the original bios , then it could be some software issues, some users said msi afterburner and other monitoring software may cause the fan spin.

btw, wich bios version did you had before flash the modded bios?

I indluded the same version as the modded bios to restore on every package.

this mean if you downloaded modded a11 and restored it using the tools into the package, you have now original a11.

if you want to flash previous versions you can DL other bioses at this topic and flash the original one.

 

It was A11.I flashed it first with Dell's A06 then A11. Then tried yours A10 i think, but had fan issues. I didn't have any issues with original untill i installed nvidia inspector which raised the voltage and i had to flash the bios. Better than shortening the system's life.
So does this mean I have any chance of restoring my stock version of Bios?
My current bios is A11, flashed from your original.

 

well, if you want to to restore A06, then try DL this from dell's original site

http://ftp.dell.com/bios/L502X_A__06.exe

however since you have a newer bios you may need to flash it a custom way.

if you got an error asking your bios version is newer, get the A06 bios file using this method

http://forum.notebookreview.com/dell-xps-studio-xps/632899-modding-l502x-bios-project.html

then run winflash withfollowing parameters (bios.wph need to be the a06 one)

WinFlash /BIOS /EC /SA /SV /BBL BIOS1.WPH

this should work to rollback to a previous bios version

let me know if you find any issue following the process ^^

 

I meant my stock BIOS was A11.

 

well, if you stock was a11, and you have now a11, then it isnt a bios issue.

to make sure you can go to bios and load default settings.

it could be related with video driver version, or some apps like nvidia tools, msi, evga precission .etc

try close all overclocking/monitoring apps and check if you still having the fan issue.

I'm using modded A11 0.85v/0.85v for 525m and running msi afterburner with higher clock speeds, no fan problems at all.

Could this be the problem - nvidia tray, and what about higher consumption? Drivers are 285.77.

 

I also have that process and I have no issues at all

running 304.79 driver version

 

301.42 no change...

 

I wnated the undervolted A11 GT 540m mod so I dled and installed it. But nvidia inspector report 1V when gaming, not .85. I though maybe I dled the wrong one but I checked the name of the folder and it was C:\Users\xxxx\Downloads\L502X_A11_540m_83_85\flash bios mod
