L502X modded bioses download (GPU voltages and more!)

I have a i5 but I don't understand what you mean by pulling the Blue pin. What is the benefit of pulling it out? Isn't the auto good enough?

Is mx4 not as good as the one you said?

What do you recommend for being the max temp for over clock?

 

Yup, once I get the eGPU up and running I'll report in and let you all know how it works. hopefully without a hitch!

 

Oh... yeah, I forgot to post about this. The Corsair Vengeance RAM works immediately after you install them. You don't need to manually change the clock speed from the BIOS (although I just leave it on Auto because that's what it defaults to every time you reflash), and it's pretty awesome :3

Of course, it doesn't really have an impact on your everyday computing, but I did get a somewhat higher score in the physics test of 3dmark11, and WinRAR compression/extraction is supposed to be sort of faster as well. But one of the main reasons why I got this RAM is because...


Just look at how sexy that RAM looks <3

 

nice modules
what is the speed?

1600 or 1866?

 

It's 1866 MHz

 

:O

so it really works at 1866!

huge thanks for the info

 

I've coded a crude way to disable battery charging automatically with Autohotkey, however this ONLY works once you have logged after starting your computer and have "opened" the desktop on Windows 8. - I haven't tested it for Windows 7. (Place the .exe in the startup folder)

Ideally, the program would toggle battery charging directly from the .exe or .dll file, but this uses keyboard shortcuts to do the same

Program (.exe):
Dell_Battery_Recharge_Disable.exe

Autohotkey script (.ahk):
Dell_Battery_Recharge_Disable.ahk

Also be aware that user input while running the script could might cause it to fail, but it should complete the actions in less than 1 second.

Script:

Run, "C:\Program Files\Dell\QuickSet\battery.exe"
WinWait, Battery Meter,
IfWinNotActive, Battery Meter, , WinActivate, Battery Meter,
WinWaitActive, Battery Meter,
Send, {Tab}
Send, {Tab}
Send, {Tab}
Send, {Shift}{+}
IfWinExist, Battery Meter
WinClose
else
WinClose, Battery Meter

 

Just downloading the A12 BIOS (L502x) with the advanced menu... let's hope that the Primary display selection will "disable" the GeForce. Then I wouldn't need the Setup 1.x software! One can only hope.

I've got the GPU and the PSU, just waiting for the PE4H-PM3N to arrive in the mail!

 

Hi, I have the same issue that you replied to here (gt 540m freezing during gaming). Is there a more updated (and tested) version than the bios you recommended here? I'd probably only be testing at stock clock speeds, although if there are no crashes I might try some OC.

Thanks in advance

 

@cjmftw

this one should be good for you

L502X_A12_540m_83_85_Unlocked_Menus_v5.rar

 

Thanks for the quick reply . Just flashed and I'll test some games over the next few days and post my results.

 

@capitankasar

Thanks for your work, I've been using your bios for quite some time now and are great. Today I repasted mi laptop and the temps dropped quite substantially so I would like to try something more than 0.85

could you provide the following 2?

Bios version: A12-latest (v5?)
GPU: gt525m
desired 2d voltage: 0.83v
desired 3d voltage: 0.90v

Bios version: A12-latest (v5?)
GPU: gt525m
desired 2d voltage: 0.83v
desired 3d voltage: 0.87v

Thank you!

 

@crapula

thank you ,glad you liked the BIOSes ^^

I uploaded both requests and them are avalible at the first post, let me know if you archive higher OCs with them or any other feedback you want to share with us ^^

 

Hey there capitan , thx a lot for those mods , im currently using the A11 advanced bios ( stock voltages ) , im really happy with the results on boot time ( uefi option ) and gaming performance ( fast strings ).
Im currently intrested in the A12 bios with stock voltages and intel vbios update , but i see no one tested it ( by the way i have a gt 540m ) and im afraid to download it but i guess i will make a test tomorrow and i will report back after the tests , thanks for all the mods. :thumbsup:

 

@CapitanKasar

Just flashed your A12 0.83/0.85V GT540M with updated Intel vBIOS (v2137) - Working fine as always

Do you know what other enhancements/fixes the updated vBIOS brings? - I'm curious to know.

_____________________________

And I would just like to share some caution with enabling UEFI, especially when installing Windows 8:

BIOS controlled hotkeys such as brightness, keyboard, wiki etc would make the computer lockup- the only way to fix it was to reinstall the OS with UEFI disabled.

 

@DSKEAARSR 2013

thanks

added to the list ^^

well, even the bios isnt tested, I'm almost 99% sure there will be no issues at all, there wasnt a single brick caused for a L502X bios.

they only machine damaged was mine, but it was cause the bios chip desoldered/soldered several times (burned due soldering heat) but I already replaced it ^^

there is also a working bios recovery method at the first post wich should work for most of bricks

well, why didnt you give a try to the 83/85 modded bios?

most 540m users say it brings extra stability and more room to OC, it was also the one wich fixed many crash issues for people having stability issues with stock clocks, it also reduce the temperatures compared with stock voltages



@NeoMesal/Matrix5

thanks ^_^

added you to the list.


well, the intel vbios update aparently bringed extra performance for OSX users and more stability in other machines while talking with Timewalker and Jkbuha from BIOS-mods forums.

so I also implemented it at the L502X BIOS, I supose even in windows it should improve the things at least a little ^^

Jkbuha is testing a newer version of intel vbios (v2158) at the 15z wich aparently seems to work also fine.

I will need to check if I can tweak the new intel vbios for the future v6 relase of the BIOS mods for the L502X.

however, I will focus before on CPU Ocing, it was the main reason I started all this project, and it still is pending to do (kinda funny I found all the other things on the way, but well, every improvement is welcome I think )


oh, thanks for the UEFI + WIN8 info.

well I stick with windows 7, but well, probably many people will move to windows 8 sooner or later, I will edit the first post to let they to know

 

capitankasar, feel free to add me to the list of users who have tested
modded A12
2D 0.83
3D 0.85

I've been using it the past couple of days, and I've been able to set my TOLUD values from the memory screen. I haven't seen any differences by changing the Primary Display Selection, though I could be using it wrong (my understanding is that this sets what video device to boot with. I wonder what PCI does?)

 

Thanks for the feedback

I've said it like 100 times before, but keep up the great work along with the guys at BIOS mods - I sure am glad that I got an L502X!!!

 

I just ran the 525m BIOS version A12
2D - 0.83v
3D - 0.90v
but underload my voltage is going to 0.95v, anyone else?

 

I still don't know how to get the right gpu bios rom file for my asus k53sv-xr1... I can pull the rom of my hp from gpu and mod it in nibitor but can u help me find the maximum 3d voltage for the Go 7150M?

How can I find the right bios .rom for my asus and I suppose this question is also how to re-compile the gpu bios .rom with the system bios to flash for my asus and hp..?

I'm getting an hp dv6000 with the 8400M GS i'd like to tweak it a bit as well

 

@capitankasar
Just finished the gaming tests with the A12 bios stock voltages ( gt 540m ) works perfectly fine , great fps increase ( games tested: far cry 3 , ultra with 1366 X 768 resolution and battlefield 3 , ultra with same resolution , results: far cry 3 17fps battlefield 3 35fps ) , since im gonna keep doing tests later today i will talk about system stability and normal tasks speeds ( copying , pasting big archives for example ) .
About the voltage modded bios , it seems that im lucky because i never had stability problems / overheating problems with my gt 540 , currently im running a pretty good and stable OC ( 792/1010/1584 ) , so as far as voltages goes im very happy with the stock ones , and it seems that i have luck with my screen quality because i have the 720p screen , and some people had a lot of problems with this screen , my friend had even to replace it because it wouldn´t turn on , but me , this is the best 720p screen i´ve ever seen.
As always keep up the great work and thanks a lot for these mods.
Hope my luck continues with other parts as well

 

@daver160

added to the list too ^^

what value did you add to TOLUD?
higher or lower? I'm curius ^^

and yeah, I also think that another option set the booting device.
it should be set to default option, didnd tested that .

well, as for PCI, I think that is related to OLD pci cards on desktop machines, I have some of them 1MB dedicated, I used one of them once while I bricked an ati AGP card while flashing a custom bios to the card, and it allowed me to flash the previous working bios by using the PCI card to be able to visualize the stuff.

at the L502X, it probably do not have any kind of PCI, but it also could be related also normal minipciexpress cards, not sure.


@NeoMesal/Matrix5

: )
and like I told ya arround 100 times, thank you hehe

yeah the L502X is a nice machine with a lot of potential inside, being limited by a locked BIOS wasnt good, so now things perform a little better

thanks ^^


@overvu

well, I double checked now to dissasembly the a12 83/90 bios for the 525m v5 and it seems fine.

it have 00 00 00 00 00 00 0F 00 5A for 3D
5A is 0.90v relating to the voltage table, so I didnt got mistaken while editing it.

it could be a driver value bad reading.

what are you using to take measures of the card?

did you tried HWMonitor ?


@chris89

well, I told you 2,3 pages ago how I extracted the GT540M vbios file from your K53SVAS.320

howver now the tricky point is how to reintegrate the file back at the bios file, I can try manually hex editing the file, but not 100% sure if that will work.

If you tell me what voltages you want for 2d and what for 3d, I can try do it for you, however like I said, I have no guarantees it will work since I never modded your laptop model bios

@DSKEAARSR 2013

thanks for the feedback ^^

well, I also have the 720p screen.

for me it is OK, but many other ppl complain about the quality, most of them dont like it due the vision range is more limited compared with the 1080 one, and the desktop is too small and programs dont fit there fine.

while I am at home, I usually hook my machine to a 1440x900 screen, its more confortable, but while I am outside home, I use the 1366x768 one, games can be play ok there, its obius it isnt as good as the 1080 one, but well, we can live it it like you said

oh, and nice OC you have there ^^

yeah, you are right, cause if you lower the voltage, it may not be stable at all for such high OC, but well, it can also be the oposite and you may reach higher stable OC, you lose nothing by trying


@Fosdi1ck

???¿¿¿

 

I just want 1.00V for 3d rather than the 0.980V and I'd be golden brother!

Thanks

I can't open that rom in nibitor well i can but it doesn't allow for any changes at all no clock changes or voltage changes.

 

@chris89

what are you trying to open with nbitor?

just open the vbios file, not the entire rom.

your rom opens perfectly with nbitor,I attached it at this post again.

well, I will check if I can mod your bios with the 1V feature

 

@ capitankasar

When I open that file you uploaded in nibitor if that's correct? It opens fine and shows asus etc and the gt540m but nothing is adjustable, no clock adjustments or voltage.

If I shouldn't be opening the vbios rom file in nibitor how am I supposed to open and edit it? I'm just a bit confused. I'm using nibitor 6.03 i know there's a 6.06 if that's required i'm not sure.

thanks

 

well, try with 6.06

anyway you dont need it, here is your modded video bios file.


now I am trying to reintegrate it at your main bios file, give me some minutes ^^

edit:
I noticed the nvidia bios is at the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_192.rom file inside the DUMP folder.

this should make it easier to edit than messing with the other files ^^

 

@ capitankasar

So I downloaded 6.06 and still the same result. The clocks and voltages etc are greyed out...

thanks

 

@capitankasar
Just finished all the tests with the new bios and my conclusions are: great changes , you are no longer locked by your system ( i feel that im on a small desktop ) , great fps increase in all games ( perfect for mixing with a good overclock , if you eneble some options like fast strings for more power ) , copy/paste was the only thing that kept the same , arround 50mb per second , system is more stable than never operating really fast and opening programs very fast , resuming , its a must download if you want to get more out of this amazing machine , thanks capitan.
Well , i think im gonna try one of the voltage modded bios and see what happens.
Oh! Almost forgot , i recommend to download the ME firmware it does help a lot on overall performance.

 

@chris89

ok, made more progress relating your laptop

the recovery name for the recovery file is K53SV.bin


also good news, I think I modded your bios

download

I may also unlocked another stuff, such as menus or other kind of stuff.

I got those messages while reasembling your BIOS



about the voltages, use HWMONITOR to ensure the card is running at 1V while gamming, feedback plz ^^

let me know if you notice also somethin unusual with your bios like enchanced menus or something else

@DSKEAARSR 2013

huge thanks for your feedback

 

No need to thank me , you done all the work , im just testing
Quick update: the mod works perfectly fine but for some reason after i downloaded it and flashed it , i cant see my laptop information anymore , hwmonitor only display hdd temperature and battery status , cpu-z stops working when he tries to start and on my dell support center it doesn´t show the info about my parts

Another quick update : everything works now i just had to reinstall the monitoring programs :thumbsup:

 

@DSKEAARSR 2013

well, I had those Issues, in my case I had load the bios default settings and staying away from the temps menus while configuring the stuff again.

if reinstalling works for you I asume when you enter the temperature and fans menu, it enable alternate sensors or stuff.

that makes sense, do now monitoring programs works better than before for you after reinstall?

 

@ capitankasar

It worked! Running 1.000V and 800Mhz stable from 700Mhz in farcry3... not sure if it's super stable have just let it run been running for a few minutes with no display driver crash yet I'm guessing I'll go look at it again...

*UPDATE* Still running stable at 800Mhz sitting at 65C so only about 5C increase but really only 2-3C increase...

I'm testing what it can do because 820Mhz seems pretty damn stable and fps is getting so damn high to levels I have never seen before lol

I might want u to mod it again but this time write the 800Mhz to the core clock in the vga bios lol...

Thanks MAN!!!

No bios options unlocked but it doesn't matter at all....

How in the heck did u do it please tell me... I wanna mod the vga bios for my GeForce 7150M so I can get some more Mhz out of the overclock lol

 

@chris89



glad to know it worked for you

well, I do not recomend to hardcode the clocks to the bios, you may want to set them higher or you may notice they arent stable at all after hours of gamming with several games, it happened to me before while testing some aparently stable OC with the 525m and I had to lower it again ^^

also I am not very experienced with the clocks table at the GPU so I would take a while in getting the required info to do it

well, about how I made it.

1- I opened the K53SVAS.320 file with PhoenixTool v2.02
2- it automatically asked me to unlock two files while reasembling it without modding.
those files were
9EF04158-EB39-4EFF-A8DA-B75119BAC9F4_1_396.rom
and
A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_192.rom

3 - I saved the modified files from the previous step into another folder, I also noticed the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_192.rom contains the nvidia 540m video bios file.
4 - I extracted the video bios manually by coping the hex part related with vbios to another new/emty file, so the file were only the vbios ready to be readed from another apps ^^
5 - when I saved the video bios, I made also a copy of that file, so I had one to mod and a backup one.
6 - I modded the voltage setting for 3d using hex editor , saved it, and used nbitor to just open the file and save it to let it mod the last byte (the last byte of the file is some kind of checksum)
7 - then I compared both files modded and unmodded video bios and checked for differences, as expected, there was just two changed bytes, the one I changed for the voltage, and the finaly byte nbitor corrected to make the checksums match.

8 - then I opened the previous modded A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_192.rom file with a hex editor and looked for those values (the differences from the modded video bios so I mod it directly at the file to integrate)

I hex changed following values at the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_192.rom file

and

9 - while I got those files modded and the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_192.rom file modded plus the GPU mod you requested, I reintegrated them into the bios replacing the files while PhoenixTool asked for it at the reasembling process ^_^

10 - the final file name were K53SVAS_SLIC.320, then I renamed it to K53SVAS.320 , compressed it and uploaded it for you ^^

I was able to do it easly because I have some experience with the 525m and 540m video bioses

 

@ capitankasar

So 820Mhz was unstable but so far 810Mhz is stable and running faster than ever lol with no temp changes damn near at all. I put something under the laptop to lift a little more and I'm getting my 63C at 810Mhz and it's been stable for over an hour at 810Mhz so 800Mhz is truly the most true and stable clock. This is on FarCry3 with 1280x720 and everything on as high as it will go except anti aliasing and only ssao and low shadows and low geometry with ultra postfx and i'm getting like 22-30fps compared to before at 700mhz I would be at like 15-20fps at these quality settings lol. At 810Mhz it's quite amazing now that it's stable and running really good too.

Anyway I just don't know how to edit hex to result in a higher voltage... I wish there was a complete guide on how to do it. Since I want to do this to my other HP Pavilion DV2615NR with it's 7150M which clocks at 425Mhz stock and I can get 550Mhz stable on stock voltage but a boost in voltage might result in 600-625Mhz or so which would help it out a lot since the 7150M is hella weak. For the 7150M i can pull the bios .bin with gpu-z and edit it and everything in nibitor. I just don't know how to re-compile it as you said phoenix tool does it. Maybe you can look at the voltage table for the 7150M for me to tell me what the max 3d voltage would be...

HP PAVILION DV2615NR GEFORCE 7150M BIOS +VGA BIOS ROM.zip

 

@chris89

well, I found the 7150M BIOS at the bios you provided.

the video bios is OPROM1.ROM and it is 62kb

I am using nbitor to edit it, since I'm not sure how to tweak the table manually by hex yet.

2d voltage is 1.1v and 3d voltage is 1.2v

however it doesnt let me to upper it more via nbitor

posible values are only 1v,1.05v,1.1v,1.15v,1.2v

it may be posible to hex edit the file to upper the voltage over that, but not sure if it will work or not.
I will edit the file with nbitor and set 3d for another voltage setting, then I will hex compare the bioses, that will probably tell me the voltage setting location and the value to change.

do you want to set your vbios, for example to 1.25v or 1.3v?

your choice.

edit:

two bits changed, the value, and the last byte, checksum I guess ^^

looking good

 

@capitankasar

I need to verify the voltage now I think it's just 1.15v so I suppose the 1.2v option would be the only available option. Since in the voltage table editor theres a max of 1.15 but in the voltage adjustments it says 3d is at 1.2v but that's incorrect I think...

I'd like to hard write my 7150m clocks in bios since I have to use this modded driver to overclock and eventually it corrupts the registry and i have to reinstall windows every time.

The hp pavilion dv2615nr has an upgraded processor with the AMD Turion 64 x2 TL-68 2.4Ghz and I overclocked it to 2.6Ghz and I'm running DDR2-800 ram rather than DDR2-667 and it runs a hell of a lot better. Just need to get 600Mhz+ out of the 3d and it'll be at it's pinnacle of performance lmao!

I'll boot up the hp real quick and get the 3d voltage. I'll get back to ya in a minute.

As for the ASUS k53 I found that 810Mhz was unstable but 800mhz is stable so I boosted the memory to 1050mhz and so it's 800mhz - 1600mhz - 1050mhz and running solid as a rock!

THANKS!

Oh yeah it would be nice to increase the shared video memory as well since it shares only 128MB and it would be insane to increase it up to 1GB! Maybe unlock some options like increase the Frame Buffer to increase shared video memory performance or something.... Since my DDR2-800 is running at DDR2-867 that helps but I think I need more shared video memory as well...


***UPDATE***

No way to know the voltage in windows for the 7150m...

 

My TOLUD was at 3.5GB, so I brought it down to 3GB. But I checked the possible values that you could set it to, it has lots of them from 2GB to 4.5GB, at 0.5GB increments.

Using Device Manager, I was able to determine that the change was made as my PCI memory bus was reading BFA00000 (BFA00000 = C0000000 = 3GB).

That's too bad that you cannot actually disable the nvidia GPU from the unlocked BIOS, but since I have Setup 1.x it doesn't matter too much to me

Thanks again!

 

@chris89

well, for some reason the slic tool isnt working for your HP BIOS

I get this error while trying to reintegrate your modded video bios



the app claim the modded file is 4 bytes bigger, but I am sure it is exactly the same size than the original one.

I just modded some bytes inside, but it is the same size.

maybe when the modded file is being compressed the size is different, idk.

well, here are the modded video bioses (attached to the post)

@daver160

thanks for the info

what do you mean about you have 1.x setup?

 

@capitankasar

Try the winplash64 bios file maybe it will re-integrate lol idk hahaha I appreciate all this help bro!

Someone told me according to the voltage table edit and the hex code that 1.2V is the only maximum available option lol...

Maybe we can increase the shared memory amount or unlock an option to change the amount since i think the 128MB shared memory is restricting it more than the clock is since there's not much fps change from 425Mhz to 550Mhz so I think the memory is bottlenecking it to hell lol

 

@chris89

tried also the file from the winplash64 folder, but both bioses are the same, the only difference is the flasher executables, but since I dont have to flash it it does not apply for me.

I tried with different versions of the slic mod tool, but it still giving issues, idk.

well, about if the card can only output 1.2v without hardware mods, well, I think then is no point of editing the video bios over 1.2 because the real voltage would still being 1.2.

about how to increase that option, well, it may be avalible at the intel or nvidia control panel at the computer, else I dont know how to mod the bios, it is different from the ones I has been modding so I probably cant help you more relating this bios.

also remember this topic is only for L502X and that is the machine I am focusing.

try asking at the bios-mods.com forums, you probably will get more help over there

 

I bought a PE4H (going to exchange for PE4L) from HIT, so they provided me with 1.x Setup software for eGPU setup.

 

oh, the external GPU package, yeah, my bad I just forgot ^^

when you said 1.x setup I though you was talking about some kind of software.

 

Well sadly my programs are working very badly , some of them already made me do a hard reset , but i did manage to check the voltage and its working with the slightly undervolted A12 bios ( 2D :85 / 3D :95 ) , the rest of the tests i done the good old way to see the temperatures i put my hand on the air exit by the left and for framerates i try to calculate in my brain , im actualy pretty experienced as far as fps goes , and you were right i was able to reach a higher clock without having to overvolt , now im running 802/1010/1604 with lower temperatures ( acording to how red my hand became after puting it on the air vent ... just joking , but i had to use my hand to feel how hot it was ) .
Two things i wanna mention is that people might be able to reach better fps , lower temperatures than me because i was listening to music while doing the tests with winamp ( not a very light audio player ) , the conclusion is you are able of some multitasking while doing some intense gameplay but since this is a undervolt dont try to go too far on multitaasking because if you do theres going to be less energy and the more you demand from the gpu and cpu the more power they need so if you like leaving a lot of stuff open at the same time this is not for you , try stock voltage or overvolt .
Once again thanks a lot for your help , quick replies and this great job with the bioses mods really great :thumbsup:

 

Im using a similar configuration , only differences are that im with 0.95V and i dont know for sure my temperature because im having problems with my monitoring programs so i use my hand , and im not that much experienced to say the correct temperature for my xps but 802mhz works really fine and with lower temperatures ( from what i could fell with my hand ) , it seems that these chips from the 500m series have good and stable clocks in betewen 800 to 830 or 840.

 

@DSKEAARSR 2013

Want me to give u links for AIDA64 and EVGA Precision X or MSI afterburner to dial in ur temps?

I was only stable at 700mhz on farcry3 at 0.980V and now at 1.00V i'm rolling hard at 800mhz in farcry 3 and some games will run fine at 850Mhz like Insane 2. Farcry3 fault tolerance is hella low so it can only work with minimal errors on the gpu. You may have a lot of faults at 0.95v but ur app will continue to run since it has high tolerance for faults on the gpu.

You should mod ur fan to 5v so u can run super cool and stable at 800mhz and I use msi afterburner on my gt540m in game to monitor temps from the OSD in game... It also displays fps clock and gpu usage.

@capitankasar

Is there anyone here on these forums who could help with the hp bios? Just so they're more filled in and all that good stuff

 

@chris89

well, I think they organize the subforums by bios type rather than manufacturer like the admins do at this forums.

since your bios is phoenix, I would try at the phoenix section

Bios Mods -The Best BIOS Update and Modification Source - Phoenix Unlocking Requests

 

Ah, I was getting incorrect voltage readings from nvidiaInspector. HWMonitor read accurately.

 

Does the i7 2630QM support memory @ 1866MHz?
I ordered some vengeance memory as well but it says it runs @ 1600MHz.
Anything special you have to do to make it run @ 1866MHz?

 

Thanks , i already got msi and did some testing , and its about what i imagened 85C , not cold but at least when it came from the factory it reached 92C ( on the edge of overheating but it didnt for my luck ) now i have a powerful cooling pad and i did some changes on the windows energy management and its geting 85C with 0.95V and 802/1010/1604.
About my gpu falts , theres not much , i ran far cry on ultra with decent 29 to 34fps and the only game bugs were very rare invisible wals on some house entrances and if im with a pistol some times i pull the triger and the game doesnt fire ( this happens every 40 to 50 minutes ) same thing apply for battlefield 3 , but im happy since its not much.
And i only have one favor to ask , how do i mod my fan?
Thanks for all the help.

 

Yeah that's funny my gpu hits only 60-65C at 800Mhz with zero artifacts and insane stability at 1v. First buy a tube of arctic silver ceramique 2 25g tube for $7.48 shipped on ebay, then pick up a soldering iron. We are going to use the soldering iron to remove the plastic by the fan so it can suck in fresh free restriction free air. Remove the motherboard from the laptop case and look at where the fan sucks in from. Then carefully make a circle in the plastic with the soldering iron and keep doing that until u cut the whole plastic piece out. Then remove the heatsink from the cpu/gpu be very careful since the heatpipes are hella sensitive to adjustments and this will screw up ur temps so be careful not to bend it at all! Clean the heatsink on the cpu and gpu with 90% alcohol and a cloth, then do the same to the cpu and gpu cores. Then apply a tiny dot of ceramique 2 on the cpu and gpu and spread it evenly with your finger across the whole chip and make sure it's very thin layer. Now let's mod your fan, there is I think 4 pins on the fan connector use a safetly pin or something tiny and sharp to pry the "blue" pin out of the connector and wrap with tape. try and remove the fan i think it's held by 3 screws and clean out the inside of the heatsink of dust. Then take a look at the heatsink when installing and make sure it's 100% flat on the cpu and gpu any none-flatness will cause ur temps to skyrocket. If you need to bend it until it sits flat so you can't teeter totter the heatsink back and fourth on the cpu/gpu. Make sure its flat and stable. Then re-install the heatsink on the cpu/gpu and use your pointer finger to press slowly wiping across the heatpipe directly on top of the cpu/gpu core to make sure the paste spreads best and plug the fan in, then put the laptop back together. Now enjoy temps in the 60-65C range under full load lol and I'm running 1V at 800Mhz and I get 65C in game for hours.

I'm gonna cry lol wish my hp 7150m had vga bios mod lol I'm running it at 550Mhz and it runs pretty bad lol it needs 600-650Mhz to be decent lol

Anyway to get more than 1v out of the GT540M? That would be insane!! 1.1V-1.2v could achieve 850-900Mhz core clock lol
