L502X modded bioses download (GPU voltages and more!)

Everything depends on your cards frequencies.

 

i don't overclock my system
gt540m
core clock 672mh
memory clock 900 mh
and using A12 advance 83-85
i recognize something with (CPUID hardware monitor) that my cpu temp's goes up to 97 and gpu's up to 90 ....i don't think that's normal
also Checked heat sink and Thermal Paste it was really poor and i could saw my gpu's brand
do you think that is the problem and what kind of bios do you recommend to me?
plz i'm really

 

If you change your paste to something good and dismount dust filter, your temps should go down ~30*C. And you'll get stable frequency.

 

I can't enable WiFi anymore and when I try my computer freezes and now when I try to install Quickset it freezes as well. What should I do?

 

You changed anything in BIOS settings? Installed Windows with UEFI enabled?

 

thanks i really appreciate your help :thumbsup: but i didn't understand what's my problem....overheating ....bios issue
or what? why games are stable on battery but not on ac power

 

Hmm... where you wrote before about AC Power? I don't see that info... For me it seems that you have too weak AC (so it discharges battery and then hang because it can't get needed power)? I don't know. It's only my idea.
Did you changed anything in BIOS Advanced options?

 

sorry i didn't write anything i thought you know about this..... all the l502s are the same they don't hang on battery but on ac power the do
people try to find solution for that with updating drivers...changing bios....changing motherboard....but it seems none of them works.....i kept on searching until i found undervolted bioses but they are reducing my system performance and as i said it seems i have also overheating issue
do i have to change any of this bios settings?

 

Hmm... I never tested if my pc doesn't hang when overclocked (it doesn't hang without) on battery... And I didn't know about this. 97*C is high, so when lower, it should stop hanging.

 

i've read your signature but
for the last question can you tell me.......what's your gpu?..... what kind of bios do you have?......and how much does your cup's temp in games that your pc never hangs?

 

CPU is i7 2670QM, GPU Geforce 540m overclocked actually to 720MHz and default mem freq. Bios http://forum.notebookreview.com/del...-more-post9066251.html?highlight=#post9066251 I'm not sure about temp. Probably around 85-90*C. When OC to 740MHz, it hangs in only some games (i.e. Deus Ex: HR) but in other (i.e. CoD:MW3/BO2) never crashes.


Edit. Today in Magicka highest temp was 82*C

 

I flashed this BIOS but the actual real max voltage is 0.98V on the GT525M.

Anyway I tested it up to 850MHz core and I scored 9606 on 3DMark06. Pretty good!

 

Guys, I think I burnt my 525m. When I run games the load on 525m is 0%. And I get about 2 FPS in the game (most probably because it switches to intel HD graphics). I did get a distortion in Tomb raider 2013. I tried it on several games and it's the same problem. Either I've burnt my GPU or either it's because of the new Gefore drivers. Anyone else having problems with the new driver? Any way to assure/check that I've burnt it? Help.

 

I think it can't switch automatically if card is burnt. Just should be black screen or BSOD. So check your Nvidia Control Panel > 3D Settings (I'm not sure how it's in english) > global > preferred GPU

 

Even if I change the preferred graphics processor to 525m the outcome is the same. I think it has to do with the game. I'm getting like 15-20fps with stock voltages and clocks. But on youtube they're able to run Crysis 3 just fine on low settings. It lags like hell on my laptop. Even though they have the same specs./

 

thanks....cpu or gpu?
i think it doesn't need high performance system
can you test crysis 3 or something like that?

 

GPU of course. Magicka is one of worst optimized games ever Many of my friends can play only on 800x600 or 1280x720 I - 1600x900 with high effects but low shadows...
Actually I don't have any game that uses a lot of GPU :/

 

then......you never get crash because you don't play
that's a solution

 

Nope. I played Metro 2033 week ago I don't play games with best graphic (like Crisis 3) but with this card we can't play on max details on older games too - so card is used in 100%. Empire Total War, Serious Sam 3, Civilization V, Call of Duty MW3/BO2, Deus Ex Human Revolution, Borderlands, Darksiders I/II, Warhammer 40k I/II, GTA IV...

 

Couple questions before I decide to flash advanced bios

What performance increase does fast strings give? Negligible?

Temperature difference with hyperthreading off?

What is the high resolution graphics setting?

 

First I just want to say thank you for doing this. The undervolting has greatly increased my gaming pleasure without all the damn crashes. I made an account on this forum just to reply to this thread.

Anyways, I think the new geforce update (320.18) for the GF540m has either screwed up your BIOS, or it screwed up with nvidiainspector. When I update the videocard to the 320 patch, nvidia inspector says that the videocard is using 1 volt instead of the modded 0.87. I reverted back to the 314 patch, and the videocard is back to being undervolted (or atleast nvidia inspector says it is). I think you need to do some more magic to figure it out, as I would eventually like to be able to keep my video card up to date. Let me know if you need anymore information from me,

Once again,thanks for the good work!

 

@FlipBack

fast strings give some performance increase in cpu marks software, also inprove intel hd 3000 performance.


I didnt tested temperature with HT off, and the last option gave me some issues while testing it.

@TwoHourMotel

thank you

glad you liked it ^^

about the nvidia inspector issues, use HWMONITOR instead to read your voltages

 

On my pc, Inspector properly says 0.87V (320.18 too)...

 

Ah ok, so the problem is actually the nvidia inspector? Thanks. I tried using HWMONITOR, but I couldn't actually find the videocard on the hardware list (atleast not by name). Can you give me a clue as to which one represents the videocard? Thanks!

 

On my notebook HW Monitor doesn't see Nvidia card too - and it's not changed name, just no card detected. So I'm using Nvidia Inspector and GPU-Z...

 

it works fine for me



running my 0.85v mod on my gt525m

running 314.22 drivers.

try adding the hwmonitor executable to the nvidia control panel, and set it to use nvidia card, it may helps

 

flashed the A12 540m .83/.85 advanced bios and it is working great. Significant drop in temps from diabling HT ( don't need more than 4C/4T for what I do). No noticeable increase in performance form faststrings but w/e. Haven't played with anything else.


thanks for the bios

 

For people who can't find the GPU in HWMonitor, add the program under the Nvidia Control Panel. Set it to use the dedicated card as default card. It'll show up then. Can't use the right click and choose graphics card model because it requires admin privileges and gives an error :\

 

That's weird, I did add HWMonitor.exe to nvidia, and the nvidia card is now the default card, yet it still doesn't show up. Could it be a problem with the GT540M? Does anyone know any other program besides HWMonitor and nvidiainspector that can tell me the voltage levels? (I still think its a problem with the 320.18 update, nvidiainspector says its at 1 volt instead of the modded, but when i switch back to 314 it tells me the modded bios voltage)

 

Is there something like External Media Bay Module for L502x? Especially like on this thread (but link is offline): http://forum.notebookreview.com/del...mma-ssd-blu-ray-optical-what-should-i-do.html
I think that it's better to use external case for Bluray instead of sata-usb cable...

 

Has anyone figured out how to control the fan?

 

Nope, not AFAIK anyway.

HWINFO can do some basic fan speed control, but it induces terrible latency issues.

There was also a hardware mod which was discussed to connect a switch to the fan wires, but I don't think that got far :?

 

I can't stand the latency. The worst part is that the laptop's fan control system overrides the setting in seconds. Unfortunately. my fan like to shut off even when the cpu is at 100C. I think my laptop overheated and crashed 5 times today.

 

My BIOS clock got reset, how do I change it back to the right time?

 

@Mang0

you can change it at the bios setup using arrow keys, numbers and tab

however if your clock keep being reseted, your BIOS battery settings may need to be replaced.

 

:3

Thanks for all your hard work! From time to time I drop by, just to find that you've added many new things everytime!

Fun fact: I have never ever seen any single laptop that came equipped with a dust filter, and that includes the L502x! What you consider to be a dust filter is in fact accumulated dust, which means that there's even more reason to remove it!

 

@Squirrel61

you are welcome

well, the dust filters are already there , they are not just accumulated dust.

here you have a pic of one of the dust filters.

the seem like stickers with some holes



and they need to be removed in order to increase airflow

 

Nice on post above.

Anyway I'm having a hard time keeping it stable at 800Mhz, I think it's the ram... DDR2 runs at 800 or 1066Mhz as does the GT540M and they decided to clock it at DDR2 900Mhz which is clearly an issue. Although 800Mhz CORE isn't truly stable on fermi until 1.025v to 1.050v.

So maybe we could downclock the RAM to it's true stable speed of 800Mhz and upclock the CORE past 800Mhz possibly...

@capitankasar

Do you know if you have my .RW Everything Report for my ASUS K53SV-XR1? I can't find it and im trying to recompile my bios... THANKS

 

@chris89

mmm, theoricall the 525m and 540m have ddr3

NVIDIA GeForce GT 540M - NotebookCheck.net Tech
NVIDIA GeForce GT 525M - NotebookCheck.net Tech

according to this site they can even support gddr5 (I didnt saw one of those GPUs with GDDR5 anyway ^^)

however downclocking the memory may increase the core OC, I didnt tested, but while I was testing higher OCs on my 525m the memory OC made the core OC unstable,

it is now on 700 mhz core and 900 mhz memory

I also didnt untouched the OC too much after a while since I also OCed the BCLK wich also overclocked the main cpu, main ram, intel graphics and other stuff and it was very delicated to make it stable ^^

 

@capitankasar

Lol yeah I didn't even look but yeah it's DDR3... 900 is a bit low for even the slowest ddr3, but I guess they made super slow DDR3-800 sticks too. I suppose the memory on the GT540m is somehow 900Mhz depending on it's engineering background, huh?

Anyway I just can't even get 800Mhz stable... Seems to crash after 30 minutes every time... I wish we could pencil mod the thing to get more voltage? Or engineer a brace bar to push the heatsink contact tighter on the core... Even if I back off the cpu to get the GPU temps at like 68C max it still becomes unstable.

In Rising Storm - Red Orchestra 2 while running damn near maxed out ULTRA high with no Ambient Occlusion, no vsync, and low shadows I get about 30+fps at 1920x1080, which is saying a whole lot. I am never able to run 1920x1080 but I dialed in the graphics for good playability.

I'm able to get 790Mhz more stable but I just hate how I am so limited. Give in I am overclocked about 200Mhz more than stock, which is a lot.

I wanna mod the voltage etc in Nibitor or Fermi Bios Editor but don't quite understand how to edit the voltage via the Hex/ Binary Voltage table. Do You?

I know we pushed it but I see that 1.0v is the max available within Nibitor, there's options 0.83, .98, and 1v. If I could push it to 1.025-1.087 I could get 851Mhz like I can my GTX470...

ANYWAY, Would you happen to have a .RW Everything file for my ASUS K53SV? I can't find it and need it to recompile...

THANKS

 

@chris89

not sure, anyway it is a fact the GPU become more hot when higher memory clocks while core speed seems almost unoticiable in temperature terms.


well, if you are on 790mhz, thats ok, messing all of this just for a 10 mhz is probably isnt worth of it, specially if you need to underclock the memory.

I posted some pages ago a voltage table I did to tweak the voltages in hex, however probably not all the voltages will work.

I supose I would need to have your laptop to get that, and like I said, I only own the laptop related in this entire topic the L502X

 

@capitankasar

I guess we wouldn't need it since you were able to compile no issue at all right?

I'm just looking to hard mod the bios with the overclocked speed... Can we hard mod in 3d to higher than 672Mhz? I dumped my bios and found in A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM

It's the gpu bios, but do I have to then dump it again to pull the rom that Nibitor is happy with?

I did this a lot on the HP DV2615NR with that 7150M but it was easier.

I just wanna create a Experimental bios for my ASUS K53SV with the GPU overclocked to 800mhz core 1600mhz shader and 1.067v...

Can we find out where in the bios is the Fan controlled? Maybe mod the fan profile to go to max at 70C/ 100% fan speed? The computer seems to never increase the fan speed past 85C, it seems to stay at 75% even know Nibitor shows 30 min to 100 max.

I guarantee it would actually change the voltage in p15 if we can actually edit the p15 to 1.025v... or hell throw 1.067 at it to get 835Mhz, and 1.087 for 851Mhz.

Can we actively change the p15 1v parameter so Nibitor shows it correctly in p15 prior to re-compilation? Can we give it a shot... Since when you changed it above 1v to 1.025 etc, the p15 value of 1v never changed. I bet if we can manipulate p15 and as long as Nibitor shows it correctly, it should truly increase the voltage above 1v.

From my fermi testing the clock multipler for the Fermi is 16 x .1875 so basically it goes 16 x 50.1875 gives 803Mhz, and 16 x 51.1875 gives 819Mhz and 16 x 52.1875 gives 835Mhz. That's what reports correctly. You can throw 818Mhz at it and it'll report 818 from the bios on gpu-z but AIDA64 pulls the clock from the Clock Generator which reports 819Mhz. Even If I set to 827 it'll report 819, so it rounds down to the closest number which complies with the clock generator. Or sometimes say I set 833Mhz or something it'll round up to 835, not 100% sure of it's behavior that way. All I am 100% sure of is it is in fact multiples of 16 x .1875. For instance the GTX 200 Series reported in 27Mhz steps so I threw 750mhz at it, bios would report 750mhz but aida64 and msi afterburner osd reported 729. So I found 756 reported correctly, did the math 729 - 756 = 27.



Thanks

 

@chris89

if you are talking about mod your bios, yes, I think I modded it in past, even it was from a different laptop, however I dont remember now ^^

I asume you want to mod the default 3d core frecuency and hardcode it to the bios.

I think I saw one guy editing clocks for the l501x laptop wich is older, however.
I dediced to not change the clocks since the OC is not the same for all people and change clocks is quite easy using msi afterburner or other OC software.

I asume there are also other OCing software for linux and other OS, so I think that is not really needed in normal conditions.

and nope, I didnt saw yet anything to control the FAN, well, I also admit I am a little away of bios modding stuff those days ^^

 

@capitankasar

Thanks.

Can you take a look at the pics above about "P15" being 1v. Can we manipulate it and add it in the Voltage Table Editor via the Hexidecimal?

As long as we can manipulate it to show more than 1v in p15, I think it would truly increase it. Since before when you set 1.025v, it never showed 1.025v, it always showed 1v in p15. As long as what we do shows up changed in p15 we are golden.

Thanks

 

oh, didnt noticed you edited the post, yeah, it is posible to tweak via hex, however not sure if the hardware will accept the higher values and set the real voltage like that.

some users said it get more hot with some of my bios relases over 1V , but I'm not sure.


yeah, it is posible, what is your default P15 voltage?

I supose it is 0.98V
in that case, the hex value for 0.98v is 62
open your bios file with a hex editor and search this

00 00 00 00 00 00 0F 00 62

as you can see, the last two digits are 62, wich is the voltage value for the P15

if you want to raise it to higher voltage, for example 1.05V wich is 69 in hex, or 1.1V wich is 6E in hex, all you need is to change it

 

Thanks only problem is sure I can change it and I'll do some tweaking. I just don't know how to get the vga bios back to it's A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM 477kb form...

I don't really know what to do from that point... I'll tweak with the vga bios file but if u could recompile or tell me how to take that 64kb vgabios.rom and recompile it into the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM that would be great.

Thanks

 

not sure how I made it.

I think I used PhoenixTool to open your whole bios, and then I found the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM file inside it, wich contains the nvidia bios.

I think all I did to replace it was open the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM file with a hex editor, and replace all the GPU file part wich is 64 kb.

it was a little annoying but you said it worked fine I think.

 

Just to let you know I'm hitting mid 60C under load at 800mhz or so at 1v, so I have head room for overclocking. Even if it's stable 85C it'll be just fine. I would only get to 85C at 851Mhz at 1.12v...

Yeah it's working fine, just don't know of the exact process. How do I pull the 64kb file from the 477kb file? If u wanna just send me a PM about that, that would be fine. Otherwise It would be insane if you would recompile for me I would be truly greatful.

I suppose there's no chance you could help me out? I just want to change the hard locked 3d mode to 800mhz which would be pretty easy to change the clock and have the p15 value show up correctly?

Can you edit the bios.rom in this file here and let me make sure the increased voltage shows up in Nibitor first before you completely recompile? I would be so appreciative bro! If you can just make one for 1.06v, 1.08, and 1.12v one that would be insane. 1.06, 1.08, and 1.12v are EXACTLY what I need. 1.06 yields 810 or so stable, 1.08 yield 835 or so stable, and 1.12v yields 851mhz stable.

K53SVAS_320_mod-(1v).rar

I just wanna

 

well, there are maybe an easier way to do it.

when you mod the nvidia bios, there will be two changes at the file itself.

ones are the changes itself, and the other one is the last byte (checksum byte)

do following:

I asume your 64kb file is exact the same file inside the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM file

1 - get your extracted vbios , open it with your hex editor and change the voltage byte I told you

2 - save the file, now open the file with nbitor, dont touch nothing and just save the file (saving the file with nbitor will autofix the checksum byte)

3 - now open the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM file, and the nvidia bios file.

4 - you will need to change the byte from the voltage and also the one from the checksum byte at the A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM file

5 - after that, your A062CF1F-8473-4AA3-8793-600BC4FFE9A8_1_189.ROM file will be modded

the values you asked in hex you can see the voltages and hex value in this table I made ^^
