Roadblock on modding GTX 460 BIOS

[FireDemon666]

Tried using NVFlash last night to dump a copy of one of my 460 BIOSes to a floppy. Well it said it backed it up OK and I booted back into windows and found the file on the floppy. The first thing I thought was that 50KB seemed a little lean for a BIOS image file.

Here is where it gets even wierder. I loaded the file into Nibitor 5.8 and while it correctly identified it as an EVGA GTX460 BIOS, that's where the party ends. Everything throughout every tab was unavailable/greyed out. Clockspeeds, Voltages, fan speeds and just about everything else was not loaded.

What gives?

You cannot use nibitor in the traditional fasion on the fermi's.

In nibitor 5.8 you have to go to tools>Fermi clocks, and tools>Fermi Voltage

Also when you checkout the clock domains and scratch your head, let me know and i'll help you out.

Are there any other editors out there that will make life easier?

I am especially interested ATM on modifying the clockspeeds, core shutdown temp and automatic fan temperatures. Voltage modding ATM is a no-no until I ditch the stock cooling.

What cards did you end up buying? Fermi BIOS Editor is much more flexible than Nibitors old musty engine, but you will have to PM and ask orbmu2k for a copy of FBE.

I went with 2x GTX 460's by EVGA. I'll give him a buzz and see what he says.

Standard EVGA cards or the superclocked ones? If their standard EVGA cards I can tell you now the GPUs will max out at around 870-900MHz. You might be able to push 930MHz on water.

Standard EVGAs.

Tinkering with the first one last night I found a stable clock of 810 on stock voltage and stock cooler. Any higher and it starts the artifact around 63C.

810 on stock voltage isn't so great, about average. I'd say even with 1.15v you won't be seeing much higher than 870. Neither of the 460s I've tested scaled that well with extra voltage.

Yeah I figured that after I saw it wouldn't scale beyond 810. Serious wtf moment.

While I'm aware 1Ghz is now a far cry, what do you think my chances are of making it to 900 with some voltage and good cooling?
