People have done it... Its just like overclocking at GTX... go ahead if you want it to say ultra but then you might have to downclock it to make it stable. Just a though. If its stable at Ultra speeds then doing it will just make the default those clocks.

On Page 2 you can download BIOS's for the MSI GTX and Ultra. Bonus for you.

It works even if the memory is different....

Instead of flashing BIOS', simply overclock to Ultra speeds?

There isn't a huge amount of difference in performance between the two anyways.

I've heard of people doing it, though I've also heard that the GTX has better Ram timings so that a GTX simply overclocked to Ultra speeds would be a tad faster.
post #16 of 19
Iv heared of people doing it when the ultra came out. The GTX is the G90 tho and the Ultra is G91. I think anyway.

Do we have a guide on OCN detailing how to do this? I want to buy the Zalman cooler and OC my GTX to Ultra speeds. I've seen Rivatuner used but I also think it will reset my card to stock speeds everytime I restart. Is this correct?

My GTX runs CoD4 @ 91fps so I can hold out a bit on the GX2. I would like a bit more power for my 3Dmark urges.

They are both G80 cores.

Yes you can. But all the posts that I've read on people doing this said that there were artifacts on high OC.

I think to successfully do this you have to keep the MEMORY settings (timings and such) exactly like a GTX on the ULTRA BIOS.
