AsRock 939Dual-SATA2 problem

[npoe1]

every time I launch Word, SiSoft Sandra, or a game my machine reboot, although I can use IE, Windows Explorer run a lot of things without problems, but some make it reboot, initially my RAM was recognized like DDR333 2.5-2-2-x, I don?t remember the command time, but I changed that to DDR 400 2-2-2-10-1T and the machine didn?t boot, later I enable the bios option flexibility option, and now I can boot with 2-2-2-10-1T, but I have this reboot problem, my RAM work fine with my MSI K8N NEO2 Platinum, and so everything else, but CPU-Z show my memory running at 128 MHZ, Memtest say my bandwidth is of aprox. 1700 MB/s, I?m using two dims of 512 Corsair XMS Extra-low latencys 2-2-2-10-1T DDR400, so anyone know what can I do in the first 10 minutes memtest was ok, but I?m now in school and left it running later will see what happen, any advice please.
Also tried with ULI integrated Drivers 2.1, after Asrock drivers (CD). Obviously, uninstalling and installing.

I?m going to order an eVGA 7800GT today from newegg, will I have problem running both cards?

Athlon 64 3000+ Venice
ATI AIW 9600 pro, Catalyst 5.10
Audigy 2
Antec True-Power 480W

First, disable flexibility option.
If that's enabled, your ram will not run 200 MHz 1/1, as the board will lower the divider to 166 or 133.
2nd, raise your VDimm to "High".
You might want to loosen those timings a bit to get it stable, say 2.5, 3, 3, 10, 2T to start.

Well, thanks for you advice it run DDR400 3-2-2-10-2T, but I couldn?t get 1T neither 2 CAS, if there is another suggestion I am ready.

thanks for the configuration, now I have the RAM running at DDR400 2.5-2-2-5-1T but in Single channel configuration, I don't know if dual channel DDR333 is better that single channel DDR400 but I will benchmark it to be sure, I will keep trying. Thank you.
