i'm hoping this isn't already answered in this thread, but has anyone benchmarked the xt bios vs the pro bios at the same speed? does anyone have proof that the memory latencies are different? also is there any type of bios tuner available for these..i've tried a few including the latest rabit and they won't work (tried xp and vista for both pro and xt bios')
i noticed that the new ati tray tools lets you mess with memory timings..since i have no idea what either the pro/xt are set to, especially since i'm on vista 64 and i'm having issues with every overclocking program, i'd rather not guess. but just putting it out there that they could be setup, maybe even better. i know that guy ketxx or whatever was making custom bios' for x1950's... any reason why we couldn't do the same for these cards?
ati tool will sometimes work for me on vista 64 but lately it has not. without it, i am not even sure if my overclocks through rivatuner are working...gpu-z reports that it is, but according to the charts on rivatuner, it runs in 2d mode even when i have a windowed bench going.
anyway i'm going to do a quick run through some type of game benchmark with the stock 2900pro speeds, and then with the pro overclocked to xt speeds, and then with the pro flashed to the xt bios. it's funny, before i installed vista (hd failure), i was up to 850/1100 for my clocks, stable... now i'm lucky with xt speeds. very strange (i don't think it's vista though...i think my clocks have progressively gotten worse)
but yeah i'm sticking with the xt bios if it works, cause overclocking on vista 64 sucks balls right now.
