Modified overvolting vbios of GTX460m on G73SW.

What's your guys opinion on ViDock? Could push a brutal card in it and have really nice vga for the future?

 

Anyone?:thumbsup:

 

Well there's a section for e-GPU in Gaming Forum. You could try asking there as this thread was created for the modded vbios of GTX 460M.

 

Hy.i just read more than 23 pages..
My question
Is it possible to biosmod the 460m in the pci id
(mine is 0d d1) and the model number and obviously the power threshold to make the card appearing identhical to another (of which i have data) that is inside the macbookpro?
This is just a cosmethic mod but is enought to mak it detectable as native card

thanks

 

I flashed the rom posted earlier in this thread called G53SW_GTX460M_192bit_volt_setting02 from this page; third post down, I get this message:

Nothing happened, it was .95 for a while and now it's back to .92. How can I get the voltage to stick?

 

Is it possible to make a vbios for the 53SW for both the P12 (lowest clocks) setting and the P0 (highest clocks)?

Thus, since the voltages are locked to certain points, is a vbios of P12 (lowest clock setting) V=0.8125 (or lower) and P0 V=9.5 (highest clocks) possible?

Thanks. I'm really just interested in a vbios to conserve battery life, but when in High Performance, inc. voltages and clocks.

 

So, I read more than thirty pages of stuff, I made a bootable USB stick, and I get all my files in order. When I tried to do a backup of the BIOS I got a message that said "this program can not be run in dos mode". I cannot use NVFLASH from the USB stick; now what should I do? Please help.


Update:
I ran it in windows with CMD in admin mode; I did not have the same problems from my previous post, I didn't get the error message as when I booted with USB, and it seems to have changed my voltage to .97. I did several reboots and I'm testing it now.

 

So my results are nothing short of miraculous. With stock clock speeds I was getting temps of 86C and higher. With my stuff OC, I would get 90C on the higher settings. With these new settings, I'm maxing out at 73C and my GPU is at 800 and my RAM is at 1479. That's just crazy. Now, I hope that my nvidia drivers will stop crashing and recovering, which is the reason I wanted to overvolt in the first place.

But, interestingly enough, GPU usage maxes out a 96%, which gives me 797 Mhz according to MSI. Well, whatever, the performance increase is still most welcome.

Thank you, gentlemen, for all your help in this thread!

For some reason, as I increase the clock speed in MSI it uses less GPU:

 

View attachment GF106.zip Hi guys. I would be very thankfull if someone could do voltage mod of my bios (asus g73sw).
Thanks a lot.

 

I used this: View attachment nvflsh.zip

Make sure you do a backup: nvflash -b [type bios backup name here]

Then, nvflash -5 -6 -A mod.rom

I did it through windoze with no problems; it would not run on boot so I had no choice.

 

Shameless bump

 

Are you saying you are trying to make a vbios that contains only 0.8125v and another vbios that contains only 0.962v, 2 vbios? Not sure if I understood your question. The 0.962v vbios you see in this thread bumps from 0.8125v straight to 0.962v when entering P0, the rest of the P-states will remain at 0.8125v, only shifts between the lowest and the highest, there's no middle ground.

 

Oh ok, sorry for the confusion.

I was hoping for a single vbios that makes the voltage for p12 and p8 0.8125V, and the voltage for p0 to 0.962V.

Stock:
P12 0.820V
P8 0.820V
P0 0.920V

New vbios:
P12 0.8125V
P8 0.8125V
P0 0.962V

Is that possible for the G53SW?

Edit: Oh I get it now. What you said sounds exactly like what I want. I'll search through the thread and try to find a link for the G53sw. Thanks!

 

No problem

The 0.82v and 0.92v you are seeing is the voltage displayed after installed drivers above 301.42, it's still 0.8125v/0.9125v just it was displayed as 0.82v/0.92v. When you see 0.962v on your current system, it should be displayed as 0.97v.

If you post your original vbios here I can mod it to 0.962v for P0.

 

I have made a backup but how do I attach it? Should I rename it as a txt file?

Also, is it as simple as using Nibitor to modify the voltage? There are .97 as well as 0V settings available. Have those been tested?

 

If you want to attach a file on NBR, just zip it and attach as long as it's not too big.

 

Ah thanks! For some reason earlier it said both the .rom and .rar files were invalid. I didn't think to try .zip.

Sorry right now I'm in Philipines and gonna be staying here for a week, will upload the modded vbios once I gain access to a laptop.
I wouldn't try 0v(setting 3),Saltius said that for 1v he had to implement a brand new voltage table so it's probably more than that. You can use Nibitor to modify it to 0.962v for P0, but that's that max voltage without adding new stuff.

 

Haha that's quite alright. There's really no reason to have any more steps in the voltage table than what's already there. 1V would probably be overkill anyway. Take your time.

Btw, what kind of temperature increase should I expect by raising the voltage?

There you go. You might see it reaching 83C with 860/1600 running Furmark or Crysis 3.

 

Flash was successful. I made a bootable FAT32 Usb drive and used the command line with Nvflash -4 -5 -6.

Nvidiainspector shows .97V and running 3dmark tests now. Thanks for your help!

As an aside, how can I set the P0 clocks to my custom overclock? 780/1500 runs very stable for me at the stock voltage, so would it be ok to set the new voltage p0 to 780/1500 instead of 675/1350?

Edit: Running 3dMark and voltage is hitting .97V. No artifacting or crashing even past 840/1500. Seem to hit my GPU's wall at 850-860. Very impressed though. Went from 3dmark 11 ~P2000 to ~P2500

 

Glad it works for you
Sure you can edit the clock zones using Nibitor and make the default to 780/1500 and reflash again.

 

Before I flashed another vbios, I wanted to make sure I was doing the right process. Because stock clocks are 675/1250, I was going to replace everything circle in blue that was 1350 (675*2) to 1600 (800*2), and everything that was 1250 to 1500.

Then save and reflash.

Is this right?

 

Yes that's correct. Replace domain 15's slot 3, 4 and 11 with 1600 and replace the same domain's slot 5 with 1500 for 800/1500, other slots can be left untouched.

 

i tried using it but i get an pci mismatch error. do i need to do anything. i think im missing something.

here is my stock bios, if you can modify mine the same way it would be much appreciated.

 

I believe that is the same error I had. I just ran it "nvflash -4 -5 -6 NEWROM.ROM"

And then just hit "y" to confirm.

Btw, I made those changes to the clock tables and it worked perfectly!

 

did you flash within windows or from boot?

 

I did it from boot. When using in Windows, nvflash said it would not support a 64bit OS.

I first made a bootable usb flash drive with windows 98 files. Put nvflash and newrom.rom. Next I booted to usb drive and backup original vbios as oldrom.rom.
Then used command nvflash -4 -5 -6 newrom.rom.

This is where I got all the tools to make a bootable usb.

 

@cozmosland,

Was the vbios saved using nvflash under DOS mode? The integrity seems to be red when checked using Nibitor 6.06. If you didn't, try using the command nvflash -b [ Insert name here].rom and post the vbios again .

 

it was saved from windows using gpu-z.

 

Ok I flashed blindly because it wouldn't let me back it up. But it was successfull.
Will benchmark and play when I'm back from town

 

iv noticed something odd now. since the bios change my pcie had dropped to 8x instead of 16..... any ideas how that happened?

my score now with higher clocks are lower than before.

 

Does it say x8 @ 2.0? It's basically the same as x16 @ 1.1 also you don't have a copy of your original vbios except the one dumped using GPU-Z. Integrity is red, I wouldn't use it.

By the way what's the bandwidth now when checked using GPU-Z? And is it still 192 bits?

Edit: which laptop are you using? Also was it bought from Bestbuy?

 

no it says pci-e 2.0 x16 @ x8 1.1.
here is the read out as it stands.
iv gone from 2200 points in 3damrk11 to 2300 with the current clocks. with temps going exactly where where were before which was a max of 92c which doesnt bother me

im curious how much of a loss im taking with the reduced pci.

i bought my g53 from xotic pc.
i couldn't make another backup. nvflash wouldn't accept the command to do it.

 

Not sure if the actual bandwidth is greatly affected, may be someone that knows more about PCI-E could tell you that. Sadly I don't have any G53 vbios with me but I remember Saltius posting a G53SW's 0.962v vbios in this thread, may be you should look for it.

 

You did not overclock your memory. That is why your bandwidth has not changed.

 

im leaving memory alone because of temp.

im just confused now as to why its down from 16x to 8. but im running the .97 vbios.

 

Oh I see. My apologies.

I don't think there is a problem. At my max overclocks I reach ~P2500 in 3dmark. You said that you reach ~2300 without touching memory so I would think that means that there is nothing wrong.

Edit: Btw, how are your temperature? Mine seems to increase sporadically but definitely warmer (no cause for concern though).

 

Your PCI-E is basically halved, it's running in x8 @ 1.1, which vbios did you flash to?

Also you have a G53JW or SW?

 

im running the one that was posted above with just the change to voltage.
my temp maxs to about 92c. which is did previously. my laptop has always ran warmer than alot of others that iv seen IMO

 

Hello everyone!
come with GOOD news!
I can create an error in the VBIOS, this error causes the voltage to be supplied to the Maxima Card. This tension must be something between 1.05 V

with this "VBIOS UNLOCKED" Indeed I am able to pass the 900Mhz speed of the GPU. what do was impossible to 0.97V

I had an increase of about 8-10 degrees in temperature maxima. that now reaches 88 degrees

for those who want to test, I'll leave the link below to download the Versions
JW SW G53, G73 JW SW
MORE CAREFUL!
As I informed I had a considerable increase of temperature.
Use for AT YOUR OWN RISK!
remember to always keep a backup of your original VBIOS.

these are with the VBIOS Clock pattern of GTX560m, use MSIAfterbuner to perform their Overclock.

Questions, feel free to ask.

Below a Print of my setup

 

my laptop is a JW

Has anyone tried the new vbios? ^^^

 

I don't know if I'd want to go about .97V. Going from .92 to .97 gave me a temp increase of about 3-5 degrees, going up another .03V would likely see a similar increase pushing me into the high 80's.

Also, I'm not sure the increase in performance would be worth it. I'd like to see benchmarks or whatever though.

 

Yeah that is a pretty large jump in voltage, so while awesome, do be careful.

 

I'm interested in overvolting my 460M on my G73JW, and am wondering what the best way to go about a minor voltage bump via a VBIOS flash. While I've never done anything with VBIOS flashing, I'm very experienced with everything else surrounding GPU/CPU overclocking/tinkering/etc. Can anybody offer some advice on what VBIOS would be the best to use? Or will I have to have my VBIOS hex-edited?

 

Pre-reading:
Nvflash

1. Create a bootable FAT/FAT32 Usb drive using HP Tools and Windows 98 files. (in the Pre-Reading)
2. Download Nvflash and dump it on the bootable usb drive.
3. Boot to your USB drive and it should come up with a command prompt.
4. Navigate to nvflash.exe if you put it into a folder. And type "nvflash -b backup.rom"
5. Reboot with Ctrl+Alt+Del

Windows should start up.
1. Copy backup.rom and rename it newrom.rom or something else. (Leave it on your flash drive).
2. Open your new .rom with Nibitor. On the file menu, select Tools -> Fermi Voltages.
3. On the bottom row, set P3, P7, and P12 to 0.8125V. Set P15 to 0.9625V
4. Apply and File -> Save.

Time to flash:
1. Boot to your USB drive.
2. In the command prompt type "nvflash -4 -5 -6 newrom.rom"
3. Hit y ("Yes") a few times.
4. Profit.

To ensure that the voltage change worked, NvidiaInspector has a voltage monitor graph that you can use.

The original vbios of the "G73JW_GTX460M_192bit_volt_setting02.zip" is the one dumped from my G73JW's GTX460M , it's been bumped to 0.962v. It should work on your G73JW's GTX460M, but make sure your card is 192 bit before flashing to it.

 

Thanks for the info. Thats extremely helpful. Although I made the worst typo I could in this request... I have a G 53JW. Does this change anything?

 

Of all the typos I could make... I have a G 53JW, not G73. Thanks for the link though.

 

No problemo! No. What you are doing is: 1. Making a backup in case something goes wrong (highly unlikely) 2. Making the modified vbios from your original vbios. Therefore it will be compatible no matter which you have.
