GTX 460 SE Bios Flash/Max Safe Voltages

post #1 of 18
Thread Starter 
Hey guys, I have an EVGA GTX 460 SE and was wondering how high I could push my voltages with a bios flash. Right now it's at 1.075V and 920/1840/2050.

Also, can anyone with a flashed 460 hook me up with a tutorial?

Cheers.

That's about what I've been running with no issues so far, but only about a week.
I really couldn't find too much info on the se's

I have mine set to a max of 1.12v but haven't yet pushed it that far as I haven't had time to test stability.

I can only get my SSC up to 910 on the core with 1.087V. Now I know all chips are different, but I would think the chips used in the SSC and FTW cards would be a higher quality chip and therefore might clock higher.

Would my memory OC effect the core/shader OC stability. I have my mem OC'd to 2275 right now. Thats the max I can get it to stable.

I"ve run at 950/1900/2000 at 1.087 but was having issues in crysis 2 for some reason (don't know if was game bug, or bad oc)
was stable in testing.

Have you tried pushing the memory higher? I can go 2275 in all games. But I wonder if a high mem clock is causing enough instability to keep me from going higher on the core/shader.

Wow, that's an awesome memory OC. Be careful with the memory on 460s though, sometimes clocking them too high can lead to a decrease in performance.

I managed to get my SE at 950/1900/2050 with 1.1V. Any other voltage increase made my temps go up to 70C, and didn't allow for an increase in core speed. Pity.

Right now I'm running the fan at 70% and my temps after ten minutes of FurMark are 62C. Not too shabby for such a cheap card.

Anyone else have any experience flashing their 460s?

So far no issues with decreased performance on the memory. I have yet to flash mine, it will be the first card I haven't if I decide not too. I just don't feel safe doing it with nbitor since it doesn't fully support fermi and ferminbioseditor is "experiential".

I might some day cause I'd like to bust past the 1.087V limit

Actually, it's pretty easy and risk-free. Use nhibitor to save bios as a rom, Fermi Editor to change settings, and flash with nvflash. Took me longer to create a bootable disk than it did to change settings and flash.

I had to use fermi editor, nibitor wouldn't give me anything to work with. If I read the file with gpuz it came up with the red light, Read it in nvflash and it was green, but still couldn't edit anything except the fans. All I ended up doing was increasing max voltage to 1.12 and unlocked to fans to 100%.

well as of last night, stable at 950/1900/2050 anything higher on the mem and it starts losing fps. I'm happy and will probably leave it like that for now.

No, I know how to flash a card. I've done it tons of times. I just don't feel safe doing it with a fermi card. It just seems too sketchy.

Yeah I get that red light too in nbitor. I don't get it in fermibioseditor though.
