L502X modded bioses download (GPU voltages and more!)

@adeebm

yeah, I can try, however I wouldnt expect a lot from this.

also not sure if those compatible laptops have a different chipset, anyway I supose they wouldnt have our HM67 chipset from the l502x




@ximinez


mmm, it could be posible, however I would need a BIOS from a laptop with that feature for this.

do you know any?

 

Not possible.. to upgrade to UEFI 2.31 you would need the entire bios upgraded as per Intel .. and rewritten from the ground up by Dell.

Unfortunately Dell's Tiano is stuck at 2.00 at the moment .. even newer laptops which come with Tiano (such as 17R SE for example) come with 2.0 .. because Dell is lazy POS.
They can't even fix their ePSA diagnostic utility so support newer versions of Intel's IGD VBIOS.. they rather downgrade it to a known compatible one so that they wouldn't need to update their shaite diagnostics utility they are so proud of ...

 

yeah, thats true timewalker, I remember when I told you they downgraded the intel bios from 2117 to 2104 while comparing the A06 with the A09.

my bad then ximinez to give u false hopes D:

I just though it was related to update one or two modules, but it seems I was wrong :/

 

mmm, found something interesting related with virtu mvp software

Lucid Logix Virtu MVP license on Z86 Boards is it possible?

it seems they hacked the bios and drivers to allow the software run on non suported mobos, maybe there is still hopes to get hybrid graphics working at our laptop?

 

If its just a matter of inserting the licence block into dsdt then its a piece of cake operation. You just search your dsdt by guid, get the apropriate rom file pass it through iasl with -d -2 arguments, add the Name(LUCD licence block in the root of your table and recompile it without optimizations. Rename to proper guid and reflash your bios with changed module.

Good news for OSX users ..
You are no longer stuck at A06 for proper sleep/wake functionality. I've narrowed down what was causing it .. turns out it's NOT IGD.
If you kindly ask @capitankasar to backport a module called PlatformSmm.efi from BIOS version A06 you will regain sleep/wake cycle even with A12.
Cheers!

 

Sorry! In My Country, I am not able to find any laptop RAMs of over 1333MHz. If someone else can confirm, I would like to buy 1 or 2 from ebay.

That would be a great help.

@capitankasar
I would like a bios mod with these voltages.

Bios version: A12
GPU: gt525m
desired 2d voltage: 0.83v
desired 3d voltage: 0.85v

Thankyou.

 

@Bkr

just uploaded it

check the first post ^^

 

It isn't working. It says "Please select correct bios image." I've tried the others they work. This one has the problem.

 

Just a quick question... and I apologize if this has been asked before.

Is it really ONLY possible to get these voltages? You can't change it to anything else in between... or over?

 

He is using NiBiTor to edit, it has these voltages predefined in drop down menus. If you take the voltage table and alter appropriate hex values it should be possible to set any voltages in between.

@Bkr

oh my bad, how dumb from my side D:, I totally forgot to include the modded bios file on that package, so the script was pointing to a unexisting file.
please dont laugh at me

ok, I fixed it now, reuploaded the fixed package and fixed the checksum code, it should works fine now

plz let me know if you find any other issue ^^


@Kitsunemimi & timewalker75a

yeah, like timewalker said, I'm using nbitor to edit the nvidia video bioses.

I dont know how to manually edit the voltage table yet.

also due the amount of increasing bios requests and the amount of my decreasing free time it would be a little hard ^^

 

I have a small issue. I used a program called HWinfo 64 to turn the fans to max manually and now gpu and cpu temps go to about 50 gpu and 54 cpu idle (browsing) and the fan does not turn on :/ they go up to 60 in game and the fan still does not turn on. I have powermizer off could that be an issue ? Went into the moded A12 bios and turned fan activation to 39 for low and 49 for high and still the fan does not rotate :/ the laptop doesn't get hot or anything but it would be awesome to fix this issue and get the fan to turn on at at least 55 CPU temps.

 

Wait a minute.. you can change fan speeds in this laptop? Please do tell. I want to know.

 

Erm with the latest BIOS update there is the option of fan activation temps by changing that you can change ur fan speed for a certain temp - the fan has 3 pre set of speeds: 0 = 0 1=2800 2=4200 rpm respectively. There is a 3rd party program which some random guy is developing called NWiNFO 32/64 for different OS versions (32 bit / 64 bit)

Further more like I said in my previous post I am using nvidia's powermizer manager tool, which allows you to force your gpu to run at max clockspeeds at all times but for some reason the fan does not respond properly and doesn't turn on even though my gpu and cpu are getting hotter and hotter :/ for example right now my gpu is at 45 degrees and the cpu is at 58 ~ 60 and ive only got a few programs active but the fan is not on at all. That wasn't the case 2 or 3 days ago. I'm trying to trace back my steps to see what caused this but I think it was the HWiNFo tool - messing up fan activation ( So be very careful when u use that program) So if any one has any idea please help.

Sorry for the not so related topic
MR. capitankasar any info on why tweaking the fan activation temps in the BIOS doesn't actually work or what I'm doing wrong ?

 

Oh, no need to rush on something like this, obviously this isn't top priority.

However I feel that a 0.9V (3D) BIOS could be REALLY popular, because with the current 0.85V, I get massive artifacting once I push my 540M past 750 MHz. But my GPU temps are all staying within the low-70s under 100% load, and I feel like I could be able to go so much further D:. At the same time, with the stock BIOS, my laptop starts to crash if I attempt a 750+ MHz OC, and the temps are a lot higher... By the way, I haven't removed my dust filter nor have I repasted yet, though I feel like I could push even more out of a stable 0.9V OC.

I don't know how many other people are in my situation, but 0.9V seems to be just right. In the future, when you have more time, please consider looking in to this because I think it would be great to have

Oh and also, I'm really loving the mod so far, and the extra menus are super sexy (even though I don't know what half of the options do). Great job you got going here, and good luck with adding more features~

 

Hey man have you tested such a OC with any games for a long period of time ? and what laptop do you have is it a XPS ?

 

@MakeYourRage

MR. capitankasar?

well, some of the Unlocked bios advanced settings doesnt work or give issues.

for example, setting DMI extended sync to enabled, causes the laptop to dont boot at all or boot really slowly by beeping while loading the OS.



I also had some issues while setting the fan settings, for example software like HWmonitor were unable to start after entering into the menu.

so if by changing some settings the computer start acting weird, go to the bios, load default settings, and modify just the ones you tested and gives you real benefits.

remember those bioses still are under testing ^^



@Kitsunemimi


yeah, you are right, 0.9 would be nice to keep a balance between performance and heat ammount.

I think if I can do a HEX compare a non modded vbios with a nbitor modded vbios, I will be able to locate the table values to change, and probably I will be able to alter them to get 0.9v ^^

I will check it

oh, and thanks a lot for your comments


@MakeYouRage

well, if he is asking he sucesfully flashed this bios mod and he is requestiong more features I supose he owns a l502x compatible with this bios mod ^^

in the other hand, every OC is different, each chip can handle different clocks without crashing, and they also act different with different voltage settings.

so the best way would be to check how far you can go with your own card , even there are others going further with their OC.

for example mine is just decent, 525m getting stable at 704 mhz with 0.85v ^^

crash on higher, I will check with other voltages like 0.9 to see if I can reach higher stable OC

 

Well do you think it's possible and are you planing on getting the fan feature to work at some point ?

 

What were your overclocking values before you flashed the new BIOS? Because on stock voltage I can only gain an extra 10-20MHz core with 10C+ rise in temps!

@ Makeyourage:

I also noticed that the same thing can happen with Throttlestop as well, but it generally works ok.

 

Lol im on with you on this one. I've played with hwinfo64 before but never seen this can be altered.

@MakeYouRage

mmm, it could be posible,

however we are focusing more on other stuff like trying to hack the ME firmware to unlock OC and ivy cpu support and more features.

I am also now trying to figure how the heck I can manually alter the gt525m and gt540m voltage tables by hand.


well, about the fan issues itself, with repaste + dust filters removal + undervolted bios I never had any kind of fan / temperature issues anymore, at meast my machine run now really cool ^^

edit: ok I think I got how to edit the voltage settings manually, it is just change 1 byte

 

Yeah the fan profiling is seriously stuffed up on the L502x; mostly due to the sudden on/off fan bursts which are annoying when your trying to get to sleep :/

Otherwise its fine in terms of cooling the laptop, which it does its job as its supposed to do

I have a friend who has an ASUS, on which the fan is basically silent and ramps up slowly in response to temperature increases. I can only dream

ok, I got how to change the voltage from our nvidia cards from 0.8V TO 1.8V !!!

all required to do is change the byte inside (parentheses) with another hex value from the voltage table I posted at the image ^^



I will keep modding the bioses by myself, but I will also make how to modify voltage for nvidia cards:

and finally, to fix the last checksum byte inside the file, al you need to is open the file with nbitor, dont touch anything, and save it with the same name, nbitor will fix the checksum by itself

 

1.8V!!! Would that kill the GPU??

 

@Matrix5

of course it will

for that reason I forgot to mention I will not test by myself any modded bios over 1V for the 525m card.

I will still relase requested versions over 1V, but allways under user request and not tested, they also will flash them under their own risk ^^

this should open a new way of stable OCs for 525m and 540m cards at the l502x

however, it is also more risky, and of course will generate more heat, I think I will make the 0.90 Kitsunemimi requested

I also will try make a 1.05v version for myself, I want to break my OC limits hehe



@Kitsunemimi

ok, 0.9V for 3d, but you forgot to tell me your desired 2d voltage

of course feel free to pick whatever you want from 0.8v to 1.8v now

note: nice avatar ^^

 

Please make a modded bios :-
Bios version: A12
GPU: Gt525m
desired 2d voltage: 0.83v
desired 3d voltage: 0.83v

I'm annoying, I know. But I'm testing for an stable undervolt.
Thankyou.

 

Oh ... that was fast... :3

I think I'll try 0.8 V for 2D... because that's when the GPU goes to 200 MHz right? Should be pretty safe, and it's always nice to be able shave off 0.1 degrees xD. This is all for the 540M of course c:
And thanks, I really like this avatar too, but these forums did some weird compression on it for some reason (it's within the size limits), and now it's kinda blurry D:

Also,

Sorry I kinda worded my other post a bit weird. What I meant to say was that with the stock BIOS (and 0.98V), when I push past 750 MHz, my GPU is prone to crashing occasionally. I actually didn't OC regularly, I only did it for a couple weeks. I was using 777 MHz, and my GPU would reach low-80s when I played BF3. Some other games brought it up to 85 degrees or so. The strange thing was that it seemed to work for a while (tested with Furmark and had a solid 2-hour BF3 session), and then one day, it started crashing every half-hour or so of gameplay. So yeah for my laptop, 777 MHz at 0.98V would be "pushing it" but I'm convinced that it was unstable because of the volts.

Oh, and the temperature of your laptop depends on your room temperature of course. During the winter, all of my temps tend to be all fine and dandy, but when summer comes, my laptop starts to sweat it out with its 2720QM, and you start to feel the heat on the keyboard.

 

@bkr

errr, there is already a A12 gt525m 0.83/0.83v located at the advanced bioses

or you want normal bios version? (with no advanced features like menus, microcode update...)

I ask because I think nobody uses the normal versions now (just voltage modded bioses) when I relased the advanced versions


@MakeYouRage

ah, ok ^^

yeah, is better to wait to have all the hardware and stuff ready before take appart the laptop, so you can do everything at once

about the dust filter, well, by removing it, it really improves the airflow, wich result in cooler temps ^^

note: Mr. sakar? lmao

@Kitsunemimi

yeah, anime is awesome ^_^

the lowest voltage avalible for 2d uh?
I like it ^^

so 0.80 for 2d and 0.90 for 3d, 540m and a12?

allright,I will go for it, I will upload the bios in like 20 mins ^_^


@all

proof of the new advanced customized voltages works.
I decided to go 1V for the 525m ^^

it works

now also even the flasher is customized haha
(diagnosis screen too ^^ )

 

Hey man you can actually use Nvidia's power manager (powermizer manager) which is a official nvidia tool which isn't supported anymore but you can find older versions of it. You can switch off the feature that downclocks your gpu making your game/whatever crash - that feature seems to be temperature related.

Also want to add that somehow the fan got fixed on meh laptop dunno how lol temps are ok now again :/ but turning off powermizer messes something up that's why I need some sort-a way to make the fans run when I want them to

 

@Kitsunemimi

your custom version is at the first post, feedback plz ^^

 

Yay <3

Alright, I'll try it out and post when it's finished~
I'll also try out a bit of gaming to see how the temps compare, but no OC'ing today because I have some homework to finish xD. I'll be sure to test the overclocking thoroughly tomorrow though.

EDIT: Worked!


Now to testing temps~

 

Making a second post because I have more different and important infos.

Guys, I forgot to mention that for my "low-70s" that I got with the 0.85V 750MHz OC, I have an external laptop cooler on my laptop. But I did my 0.98V 777MHz OC back when I didn't have this fan, and that was low-80s. So please let that clear things up a bit >.< ! I'd also like to add that the temperature that I got WITH laptop cooler @ 0.85V no OC was exactly 70 degrees.

To do a proper sort of comparison, I'll try out some BF3 at stock clock with laptop cooler, and then one with no laptop cooler, and 777 MHz OC. That way, we can compare to both 0.85V and 0.98V.

EDIT: Alright I have some results. These tests were conducted on the opening sequence of the "Going Hunting" mission in BF3. That also means that they usually last for only 6 or 7 minutes each. They are by NO means a sustained temperature test, therefore they're not that accurate for comparing to your own. But 7 minutes is about long enough for the temps to mostly level off, so the results should be pretty accurate relative to each other.

0.85V w/ cooler, no OC: 70 degrees
0.9V w/ cooler, no OC: 74-ish degrees

0.98V NO cooler, 777 MHz: 81-83 degrees
0.9V NO cooler, 777 MHz: 78-80-ish degrees.

Note that the no-cooler results tend to continue to heat up over time, so the actual max temps may be slightly higher. The cooled ones will usually stay around the same.

Anyways, we can see that the 0.9V results do sit quite nicely in between, but sadly, it's still a bit hard to compare everything because of the difference my cooler makes. I'll continue to report my temps when I go more in-depth with the OC'ing tomorrow, but I can't really say much more about comparing the voltages. ...Although my guess for the 0.98V with cooler and no OC is around 78-79 degrees, and 0.85V NO cooler and 777 MHz is maybe 76-77 degrees if it didn't crash (OC'ing seems to add around 3 degrees, and no-cooler adds about 3 more).

If someone feels like hopping back and forth across the voltages and doing a more thorough test, then by all means~ I feel like my post leaves a big gaping hole in the data that needs to be filled in xD
Oh, speaking of which, I really like that change to the flasher screen

 

Strange, I'm getting 1V across the board (Nvidia Inspector, HWINFO, GPU-Z). What program are you using to monitor the voltage?

EDIT: CPU-ID is reporting 0.9V

@Makeyourage

My bad! - I meant in the context that throttlestop can also prevent the fans from running, like the HWINFO fan tool, even when temperatures approached 80C+!

 

Can someone tell me what I have to adjust to get my fan going into it's highest speed at a lower CPU temp than current?

My bios has the following:
Active Trip Point Hi Fan: 71
Active Trip Point Lo Fan: 55
Passive Trip Point: 95

But my CPU cores get to 90 degrees before the fan goes into turbo mode and cools to 75. I would have thought considering the bios settings, the fan should kick in when CPU gets to 71, but it doesn't. I tried adjusting the Passive Trip Point down, but that just seems to reduce the power to it to keep it cool.

 

My laptop keeps crashing and I have to do a hard reboot every time. With stock voltages the laptop crashes quickly while with the modded bios it gives me extra 20 mins. I am running at 740/1480/1100 at 0.85V for both 2d and 3d. Am I overclocking too much? Should I underclock it to the 550m speeds? (740/1480/900)

I don't want to play games in stock clocks. Please reply. And btw what voltages and clocks are you running on?

 

well, that is a high OC, and chances it become unstable are high, so yes, i would set the memory to 900 first, then if it keep crashing, reduce the cpu clock by 10 mhz until it stop crashing ^^

before i was on 0.85v/0.85v and it worked fine to reach 704 mhz with good temps

now I am trying other voltages, will leave feedback when got something solid

 

Hi @capitankasar,

Can you backport PlatformSmm.efi (GUID of CB73C3D9-2F01-4342-AE67-04DDE5264092) from A06 to newer BIOS(such as A12) so that it would fix sleep/wake on OS X?
Timewalker has already done it for the L702x BIOS and he says that he can't decompress L502x bioses for some reason.

Any help would be greatly appreciated.

Thanks.

 

@shrikant
sure, I can try

just let me to know your desired voltages and gpu ^^

 

it's irrelevant for OSX I guess (Optimus is not functional). So a stock one will do perfectly fine ...

 

@timewalker75a

ok, I will go for it.

anyway, on my previus tests, I noticed two flashing attempts failed, (the flasher didnt even apear after rebooting)

all I did on those attempts were trying to include the a06 module (PlatformSmm.efi ) and the dsdt with virtu vmp you modded.

I will try to flash those stand alone modules one per one to detect the module giving issues.

 

ok, I found the issue, it wasnt the PlatformSmm.efi module, I just tried to flash just the PlatformSmm.efi from the a06 on the a12 version and it was fine.

I supose the dsdt patch is causing issues.

anyway since the PlatformSmm.efi backporting worked I will relase the generic version with fixed sleep for OSX

 

the flasher wasn't starting because of DSDT reintegration.. still have to figure this out I guess.

 

ok, I uploaded the bios with the OSX sleep fix to the first post ^^


edit:

I just flashed another voltage modded version for 525m

lets see how far I can go with OC ^^

 

You forgot the new VBIOS for OSX BIOS .. it's supposed to crank up the VESA resolution up to Full HD..
