7900GS + GTXBios = 7900GSX - Page 49

When i had my 7900gs overclocked i still used my 90w adaptor and it was fine and never had a problem but since ive gone up to a fx2500m i have bought a 130w adaptor. I must say the 90w was very hot to the touch though so to be on the safe side you could get the bigger brick as they dont cost too much.

Hi, i did the 791GTX flash on my rev 1 GS, works fine! Just too bad as with the rev 1 i can't push much the clocks..

But, it always stays at the max clocks in windows, the GS bios used to go back to the second clock set to save power (and under keyboard heat) while in windows, anyone else experienced this?
Any tips?
Btw, using Vista.

edit:
Allright, sorry, this was an issue with the 'NBF Mobileforce VS driver 174.31', i'm back with the 'XTreme-G drivers 168.28', works fine, also works fine with windows update drivers.

For me max clocks are 650/610
3DMark05 : 9612
Quite an improvement over the stock board!

Thanks for this great mod!

My 7900gs burnt up, and Dell just sent me a replacement. I want to flash it again like I did before, but I forgot how I checked teh revision. I want to make sure they haven't released a new revision.

The links no longer work. Does anyone have working links to those old sites?

You can get nibitor and check the bios version or look in the driver tab

Please, can somebody reupload the original ISO image beacouse is not available anymore.

And if I will upgrade my 7900GS (Inspiron 9400) to this GTX, I will have FULL Shader 3.0 Support in videocard? Im asking beacouse I downloaded the GRID demo and when Im launching the game Im getting the following error message:

"Your graphic card does not support Shader 3.0, which is needed by the game"

As far as I know, all nvidia cards have been sm 3.0 since somewhere the 6 series, specifically the 6800 definitely was sm 3.0.

So flashing your card will not help you at all. I have the rom's in my signature but you would have to make them bootable yourself.

if there is someone that still has this img, please email it

I just got a new toshiba laptop with a 7900gs in it, will this Flash work in this laptop?(P105-S9337)

I want to do this mod, but I am a complete flash noob, and the instructions for noobs seem to complicated for me (thats how noob I am). What's the easiest way to go about this? Also what programs/drivers do you recommend I should install? I heard notebook hardware control is good for monitoring temps and cpu speed.. what else? and what version drivers? thanks

It might be possible that you could overclock without flashing the BIOS on your card. Anyway, no these roms would not work for you since they were pulled off of Dell cards.

If you are not able to overclock your card, I suppose it would be easy enough to unlock a Toshiba (MXM?) rom but I'd need an original copy from the card.

So you think I'll be able to overclock, just not to flash it to GSX? I got so excited when I saw the performance increase of the flash..

You're most likely gonna have to settle for a regular overclock. Unless you can find a GTX toshiba rom you are pretty much out of luck.

Hi i will overclock my 7900 gs rev 0 my original clock core 375 and mem 507


How mutch volts can i take?

can i take the 7900GTX bios with 1.24 volts with 500 core and 1200 mem?

i see this in the forum , and i found it on the juanlu page with the bios list, or know somebody witch bios can i take from the list

its my first overclock, please help me

I will write a mini tutorial later explaining the various approaches.

i need to know, volts and witch core and mem clock can i max take, i do overclock with bios flashing, i will don`t kill my 7900 gs

Sorry man, I will be away from the net and my computer for another day or so. The tutorial will definitely get started on soon though because these questions are somewhat frequent and I want to cover all the angles.

I know I'm super late to join the party, but I can't seem to figure this out. When I boot from the 7900gsx.iso I get a Microsoft Windows 98 Startup Menu with the following options:
1.Boot with emm386 (most compatible)
2.Boot with emm386 (max memory)
3. Boot without emm386
4. Clean boot

Enter a choice:

What. The. Heck?

Okay, just figured out that I'm supposed to us NiBiTor in windows. Hehe. But now I have another puzzler... Whenever I try to open a Bios I get the following error: E/A-Fehler 103. The program also "Couldnt find VGPU info. ;(" and "Couldnt find Clockrates. ;(" Any thoughts?

???

thank you! but which one should i choose for my 9700gs??? dont see .. 780GTXNN ??? what is this or 780GTXUN ??? + should i check something?revision? before OC? -Kai

Hi,

I assume you have a 7900 GS (you write 9700 GS which exists as well).
If you want to do the GTX-Mod therefore flashing the card to "look" like a GTX (it's recognized as a GTX and can overclock higher but DOES NOT perform like a GTX, 'cause the GTX has got 24 pixel pipelines compared to the 20 pps of the GS).

If you want to go the whole way flash the 790GTXUO.ROM
If you want to just enable overclocking flash 790GSUOV.ROM OR 791GSUNV.ROM (according to your revision! 790 is revision 0 and 791 is revision 1! If you flash the wrong revision, your card can't display anything anymore so you need to flash it blindly in order to repair it (if it's repairable at all)!!!)

I take no responsiblity if anything goes wrong! You do everything at your own risk!!

//EDIT:
You can look up your GPU's revision in BIOS.
- Revision 0 (rev.0): with bios 05.71.22.16.13.
- Revision 1 (rev.1): with bios 05.71.22.28.01.
The long number 05.71. ... is the thing you want to look for ;-)

You can look up what the abbreviated names stand for here: http://web.archive.org/web/200709121...jlgm/peng.html
It's the original site (or at least a backup of it!). The 790GSUOV for example means: it's a BIOS for 7900Gs Revision 0, the memory timings have been optimized, overclocking is enabled and the card is voltmodded (higher overclocks run stable, but more power is consumed => more heat and less battery)
