I have a Nvidia PNY 5900 video card, and I have discovered this card can be upgraded to a 5950 ultra by using a 5950 bios.
I have tried to overclock this card before (to get a higher FPS in splinter cell) and got bad results - textures in many games were "whacked out." I used the coolbits Nvidia tweaker to overclock it.
Right now, my card is at factory conditions and has been for a very long time. That means it's running at 400 core, 800(850?) memory.
The site claims this hack will jack my card up to 475/950. Not a bad improvement, but it does claim this can diable / muck up the TV out and VIVO functions, depending on card and bios. Good thing I'm not using either.
My card's current temp is 46 C (GPU).
Here's what I want to know:
1. Will this work, provided I follow all instructions?
2. This procedure has a backup, but will it fry my card to hack it? (Overclocking it myself, back when I was very stupid, apperently has not hurt it.)
3. I know very little about OC'ing. I do know that it will increase the temp of your GPU a lot if you go too high. If I use this hack on my card, and it works (that would be AWESOME!), will the default fan mounted on the card be enough to keep it cool?
