Mod rom on Geforce 3 core won't stick

[Sagei]

This is one for the pros. No off the wall replies please.

I have a Visiontek Geforce 3. (original release)(200/460)

I do not like watching my monitor black out every time I boot up using Coolbits (or any other program for that matter) to overclock my graphics card.

So I decided to modify my Geforce ROM.

I used RVBedit to capture an image of my Geforce BIOS. I then went to the initialization screen and change Core speed to 215mhz and memory speed to 490mhz. Saved the image to floppy.

Used NVflash to flash a new image onto Gerforce BIOS.

Everything works great except Core speed stays at 200mhz.
Memory speed did stick at 490mhz.

Tried flashing 3 times, but each time the core speed would not change from its default setting of 200.

Does anyone know how to get around this?

Again I do not want to run any O/C program.

Try to flash it to say 210 or 220 maybe the program doesn't do it that high/low.

Use a diff program, DON'T use coolbits, the programs work fine and you don't risk screwing your card if you set it to high.
