My system: P4 2.6 Ghz; 1 GB DDR RAM (800 FSB); MSI GeForce FX 5900
XT (overclocked to 425/763, from stock of 390/700).

Huh? Hm. I've owned my FX5900-128 for over a year now, and I just
installed the 61.77 driver set. Merged Coolbits. Checked the Clocks
section, and it's defaulted to 2D-300/850 or 3D-400/850. I'll set it to
3D now, then go run Doom3 and check the timedemo. But your clock speeds
look more like 'LE than XT??? Or is the nomenclature just confusing me?
I'd thought XT was more Ultra like?
McG.

XT is clocked slowest in the 5900 family (390/700 -- some are 400/700).
Ultra is 450/850. Vanilla 5900 is 400/850. So you must have the plain
(non-ultra) 5900.

There is officially no such thing as an "LE", but some manufacturers stuck
that tag on their cards. XT is definitely NOT ultra like. It is more like
Ultra - "lite".

This page will explain the 5900 family to you:

But note this quote:

"Despite the slower memory frequency (700MHz effective versus 850MHz), the
5900 XT is able to keep up with the GeForce FX 5900 128MB in many benchmarks
thanks to the lower memory timings its 2.8ns BGA memory boasts."
