That's a good thread, and on the second page someone asked about a BFG 5900NU.

Have you thought about doing the Bios flash first?

From what I heard, flashing a 5900nu to a 5950 BIOS should raise the volts on the RAM byitself. Someone correct me if I'm wrong.

Don't know about nV memory voltage control, but I am fairly sure that the core voltage is controllable by BIOS/Software, as it is reported to change when you go from desktop to 3d apps. Do nVidia FX cards have memory voltage adjustment?

L337 M33p, they have 3d voltage/clocks and 2d voltage/clocks.

It adjusts the core voltage +.1V for 3d.

The bios flas raises the ramvolts slightly, but A vmod would IMO be easier.

Why doesn't someone look into the difference between the 5900's and 5950's bios and see what changes. I have read the the timing on the memory or somthing changes also. Maybe someone can take a few different bios and make 2 or 3 for different setting's.

1. 1.5gpu\2.75 mem 425\900

2 1.55gpu\2.8 mem 450\950

3 1.6 gpu\2.85 mem 500\1000

And see if they cant get a better timing setting if there is any in the bios.

The 5900XT's have better Ram timings, someone might try flashing thier 5900NU/U with a 5900XT bios and see if they gain anything.

Want be me but it would be nice if someone combined the 5900xt, 5900U and 5950's bios together to make one kick aress set.
