Try 3-3-3-8 T2, that should work on any Ram. If you need looser timings you might check for compatibility between the Ram and the MB on ASUS's web site.
Is your Ram a dual-channel kit? If so, what slots are you’re Ram in; some MB's can be sensitive to that.
Are you OCing? Remember your Ram Mhz is locked to the CPU speed X 2.
Just some generic thoughts.
Try to raise AGP from 1.5 V to 1.6 or 1.7 V. Disable AGP fast write, also disable "AGP 3.0 calibration cycle" if enabled ( or enable it if disabled ), the same for "DBI output to AGP transaction".
I hope this helps...
I would agree with YYD, it sounds like a video problem. To test that theory try running Prime95 or SiSoftware's Sandra Lite 2005 (in Burn-in mode) both are free. Run them for 6+ hrs, if you encounter no problems it’s not your CPU or HTT bus. That would make me think Power Supply or Graphics card. You might try down loading a Graphics test program (3DMark2001 SE from MadOnion for example) to test your GC under a load, change settings to run continually at highest resolution..
i hate reading all these stories but im afraid i am experiencing the same results...
i just got my new pc (upgrade) home and the system runs dang fast and stable...however, when i load games like bf2, it loads and will go thru the menus etc and connect to a server...BUT THE INSTANT i set foot on the map (direct 3d) it crashes... every time... im going to try the 4x setting in bios and disable the fast write as several has mentioned and reply back shortly with results. I have noticed that when trying to run in 1024x768 as it was before on the same card, it crashes instantly like i mentioned...however if i lower everything to low settings and go to 800x600 it will work a few seconds just fine...then crashes... so this has me puzzled...
anyways the system is as follows
2 gigs of corsair ddr400 (2x1gig)
430 watt antec
amd 3500 x64
western digital 10,000rpm 150 gig sata
ati radeon 9700pro
