Just installed my Diamond Viper V770 Ultra on W2k with 28.32_winxp.exe drivers. Windows sees it as PRO. Everest/Aida64 detect it as Ultra - 150/183Mhz.

Run some benchmarks with Q3A demo on P2/450.

I have these two versions:

From Creative:

From ASUS:

Unfortunally I dont have a diamond version to compare with

Hi all.
I have this Diamond Viper V770 Ultra. On the label it is marked as an Ultra and with the Diamond drivers it is detected as an Ultra. Sweet... Now here the trouble begins. I tried to install both a Detornator 3 driver and the nVidia driver version 45.23 and they both detects this card as an Pro.

Anyone here, that has an idea on what is going on with this?

You need the Diamond Viper V770 ultra drivers for this card. Generic Nvidia drivers wont work to show the card as Ultra..

Yup. I found out. I do not have the card anymore. Sold it.
Yet that was years ago, as I have a couple of passive cooled Creative/Compaq branded TNT2-Ultra's anyway.
