GTX 400 Overclocking/Modding Thread

Thread Starter 
The purpose of this thread is to share and discuss various hardware and software mods for the GF100 series graphics cards.

To convert .bin to .rom: just rename the file extension


GTX 480 Stock BIOS
GALAXY
EVGA
Zotac
GIGABYTE
ASUS

GTX 470 Stock BIOS

EVGA SC
NVIDIA Reference BIOS 1A.00.02

GTX 460 OVERVOLTAGE BIOS
EVGA and MSI in one RAR file - Credit: NCSpecV81



Best performing BIOS for GTX470 - also known as "grunion's ocx480 bios"
EVGA Identifying - 1.15v max. - Temporarily down.
EVGA Identifying - 1.21v max. - Temporarily down.



If your shaders are limited in afterburner - download NVIDIA Inspector and click "unlock max"

Flashing the BIOS with nvflash.exe
nvflash.exe -r {press enter} - this removes write protection
nvflash.exe -4 -5 -6 BIOSName.rom {press enter} - hit the Y key a few times to answer yes.





If anyone wants to take a look at the differences between the 480/470 bios, I have compiled screenshots of side-by-side comparisons of zotac vs evga, 470 vs zotac, 470 vs evga480, and 470 vs 470 sc here.

TUTORIAL for voltage control and extreme overclocking:

What you need:
MSI Afterburner 1.6 beta
Xtreme tuner HD beta
ASUS SmartDoctor 5.57
EVGA Precision 1.9.2(optional)
ASUS bios for your 470 or 480 (links above)
  • MSI Afterburner will control your fans.
  • Xtreme Tuner HD will modify your core clocks beyond the sliders in SmartDoctor/Afterburner
  • SmartDoctor is used to set voltages

Use Xtreme Tuner HD to flash your BIOS.
Afterburner now supports voltage change.

Hey man, can you e-mail those bioses to xtremetheme@mvktech.net

He's the creator of NiBiTor and he's looking for GT400 cards bioses. That way he'll add support for these cards to NiBiTor so we can edit the bioses and change settings and perhaps even voltage.

So how high have you clocked your 470?

So far I have been to 817MHz, but there are too many artifacts. I need more voltage. I'm messing with earlier drivers now.

What are you cooling it with, and how are your load temperatures?

I have stock cooling. I just ran Vantage at the GTX 480 clocks(700 core 924 memory) and 66C was the maximum temperature.

The fan becomes audible at 72%. I ran kombustor with fans at 72% to see where the temps leveled off. 77C.

Really looking forward to these results.

I'm hoping what happened in the other thread does not happen in this thread. Also,





Also, do you think people would have trouble when flashing the 470 to a 480 due to the different memory amounts and bus in each card?

EDIT: And WTH, my 5850 only gets 90FPS in Kombustor.
