since its possible to flash an fx 5900 to 5950 i wonder if u can flash the 5900xt to 5950.

You help me because i suck.

Sure, if your memory and GPU can handle the overclocks.

Probably ot too likely, though. Memory should be alot slower on an XT, but I'm sure there's someone out there who'se tried it.

I've heard people flash from 5900xt to 5900, but not to 5950 Ultra. It may be possible, but only with very good cooling and a lucky card. If you want to flash it, overclock the card to the 5950 speed, and see if it runs stable. If it does, then flash it.

FX5900XT cannot get to FX5950U's speeds, since the 2.86ns Samsung memory refuse to go from 700 to 950mhz.

Its been done. You have great chances flashing to a 5900 Ultra successfully.
I'd be satisfied with that..
but o/c and find out if it will work on yours.
The flash will probably lower memory timings (allowing higher clocks) and possibly raise the voltage on the card a bit as well.
Combined, if you can get the mem within 50mhz you should be ok to flash.

Its one of the reasons that this card remains such a great value. I flashed some 9800 non pros and found that trying different bios can be worth your time.
Some have different settings and allow your card to go higher.
I'd rather have slightly reduced timings with higher clocks myself.. just depends if the gains outweigh the losses in performance.
In my Radeons case, it did by far.
Just be prepared to lose the card and dont attempt without a backup of your current bios as well as a PCI video card so you dont have to flash it blind if it doesnt work when you think it might.

Never seen those, the Leadtek card uses 2.86ns Samsung as far as i know.

You've seen it been done? If you can't overclock your card to 840-850mhz, and you don't have a spare PCI vid card, then forget it. Loosening timings and slight voltage raise doesn't gain you 50mhz.

It made quite a difference with just relaxed mem timings (no volt increases) on my 9800.
Maybe not 50mhz but somewhere in the ballpark.

Flashing from the 5900XT to even standard 5900's bios tends to create problems, because of different memory. XT uses Samsung, 5900, and 5950U all uses Hynix.

My Infineon 9800 non pro used a samsung bios correctly. As far as I know, I was the only person on the web that got Infineon boards to hit samsung chip speeds.
The actual brand only matters if the quality is different, and my overclocking results were completely dependent on which bios I used.
