Got a Leadtek FX5900xt now, i can overclock to the fx5950u speeds without problem but when i flash i get this ****ed up windowsscreen.
So my card isnt flashable? or maby with better cooling?
I tried the flash with stock cooling so without memsinks.

I have a 5900 Ultra and i want to put it at a 5950 Ultra... Do you have a link for the Bios i would use. Or is this even possible b/c i read earlier that you had to have a Non-ultra 5900? So i wasn't completly sure

Thanks for taking ur time to read this.

When you have an 5900u you have better ram (than the xt) on your bord, so i guess you have a good chanse that it works.

WOW! This thread is a real gold mine! Thank you to all who have so richly contributed.

I'm new here and came accross this place only a few hours ago, looking for info and feebacks on 5900 Ultras.

I will be upgrading my Ti-4600 to an nBOX MSI 5900U 256MB in a few days and after looking around, I'm seriously thinking about flashing the card to a 5950U. What can I say except: DOOM3!!!

If I oc my 5900 to 5950 speeds and its stable, would there be any other reasons to flash the card?

For those of you who flashed MSI cards, which BiOS did you use?

Has anyone found a VIVO fix after flashing their cards?

Because when you just overclock the card, you'll need to re-apply (or let a program re-apply) your overclock everytime you reboot. If you flash the card, the settings are locked inside the bios of the graphic's card, so you don't need to redo all those things again. A flash overclock is also known to give a slightly better overclock, probably because windows isn't interupting the card's work by changing the fequencies.

wrong answer buddy.

flashing will increase voltage to the core and change memory timings, allowing you to reach even higher overclocks.

you'll have to find the correct flashrom though

Ok, thanks!

I'm reading through some more of the posts and noticed the mods were done with motsly 5900 non-ultra cards.

But theoretically, a 5900 ultra 256MB can be flashed into a 5950 ultra 256MB, right? Sorry for the uncertainty.

Also, I just downloaded two MSI bios from mvktech.net and was wandering what was the difference beetween them. Has anyone here flashed their MSI cards with MSI bioses with success?

About the VIVO, I found this late last night: http://forums.guru3d.com/showthread....0&pagenumber=1

I don't know if it will work, my card will be here Monday so I'll try then.

**EDIT: I just the post right above my prevous one that answered my question about flashing 5900u into 5950u. :super:

I got my 5900 Ultra now. I know it is recommanded to overclock it to 5950 speeds to make sure it can handle the flash.

But which program do I need to overclock and see my vga temps?

Powerstrip to overclock
the temps can be seen in the video card's advanced properties.

Riva Tuner allows you to overclock & check temps at the same time ->
