GTX 465 BIOS mod?

post #1 of 2
Thread Starter 
Hey guys. I have an EVGA GTX 465. I have been using MSI afterburner to overclock. I have used Afterburner to create a dynamic fan profile: Idle, 60% (no noise is the reason, idles at 32) and once it hits 60c the fan goes to 100% It keeps it cool, tops out between 55-62 depending on the game or benchmark.

On Afterburner, the maximum core clock I can get with no artifacts is 816. (so shader is 1732, memory is at 1750, but at stock memory the core clock limit applied) The voltage is at 1087mv...

But I want to push it further!

I've seen some people reach upper 800s in the core with 1087 so I don't know if it's my card specifically or what. I notice that the graphics card is the weak part of my build, as the overclocking I do does affect my FPS, and not just minimally. I AM running the ASUS mod, so it has all 448 shaders unlocked, though I'm not sure if that would affect stability limits or not.

I have never in my life done a GPU bios mod, so I don't know how to backup/restore the image or whatnot. When I had a GTX260, I could push the voltage as far as I wanted, but I found the ideal voltage while not heating too much was 1120. Seeing how cold my temps are and how much heat Fermi can take, I would like to see how much farther I can push the core as I imagine the only thing that's stopping me is the voltage. So how can I get around the 1.087v limit?
