How to flash my GPU BIOS?

I have an HP Pavilion dv9312tx having the graphic card NVIDIA GeForce Go 7600 with normal core/memory speeds of 450 MHz/761 MHz. I have currently overclocked it to 500 MHz/860 MHz using Rivatuner. (3D Mark06-2623)

BTW I am running Vista Ultimate x64 and the driver is 174.32 from HP website. The video BIOS version is 5.73.22.50.a3. I read in many forums that I can flash the BIOS in my GPU to enable higher clock speeds. If so,then how to do it?

What are the maxumum clockspeeds I can reach without damaging my card?

 

If you want to overclock use Rivatuner.

Flashing the vBIOS isnt easy at all.

 

That is not a good idea. I'll just leave it at that.

 

Well flashing the BIOS is risky I know, but has anyone here done that on their laptop GPUs?

 

Only a dell. I sucessfully dropped the vcore of my ati X1400 last year by modifiying the bios. It was easy for that part, but I have no chance of doing it for my current notebook as the system bios IS the GPU bios. My advice, don't do it unless you can afford to throw your notebook away due to screwing up the whole system.

 

I found bios flash is very easy, all you need is 2 commends with nvflash.

 

Can you please give the details regarding the flashing process? I mean what I have to do.

 

It is easy if your GPU bios is not integrated into the system bios like mine is . I would dearly love to flash my bios to reduce the voltage on the core (get it running cooler) but can't even read it out of the damn thing so I'm stuck. Unless anyone can show me exactly how to do it to a Zepto 6324W, I'm not going to risk bricking my notebook.

 

Actually my system BIOS is Phoenix F2C. So it is different from my video BIOS. But I have no idea how to do it and using which tools. I downloaded an utility called NiBiTor from Softpedia but that utility is unable to detect my GPU although it says that it supports Go 7600 in its documentation. So I am stuck.

 

You could do it, but as far as I know , both the geforce 7600 and the ati x1600, which are pretty much equall, run hot.
OCing via BIOS would be risky.
If for some reason you still want to do it, and again, I advise you against it, PM Zfactor .

 

I have not flashed nvidia cards... atleast I dont remember doing it but I flashed both of my desktop 4850's and it was a VERY VERY good thing, I was able to increase the fan speed, raise the core voltage and overclock them higher than the normal limit (720/1050)

 

You need to nvflash to read the video bios. You'll need to do it in DOS though as windows will stop you from accessing it properly. Then you can use nibitor to edit the bios, then use nvflash to flash the video bios. I saw a thread on here somewhere about flashing your video bios, it gave a good walk through, I can't remember where it was, if I do I'll post here.

 

you need to make sure your card ACTUALLY has a seperate BIOS,so it must be an MXM type card. My laptop is not MXM type and i was trying to unlock the other 32 sream processors to make it an 8800m GTX, didnt work.

and its actually not hard at all.

 

Well after careful consideration of all the probable risks with flashing,I have decided not to flash it.

Anyway ,my Go 7600 idles at 65-70C and goes upto 90-95C while playing games. Since I have already OCed it to 500/861, how much do you think I can push it further without any artifacts? Any guesses?

 

Id get a cooling pad or something above 90c is too hot for my taste.

 

If you want to know how to flash v-bios then read my guide ( See my signature for link)

 

Honestly, if you`re above 85C , you should stop now.
Anything above that is a danger zone.

 

name one card that doesn't has integrated bios?

 

I wanted to flash mine with nvFlash, but I couldn't find one newer than the currently installed BIOS Rev. 5.73.22.50.A3
of the nVIDIA GeForce Go 7600 running in my DV9200. I even had the boot floppy all ready to go ...

Bios Agents tell me the video bios is old and out of date ??
Everest Ultimate says I have 2 video cards
