I recently built a P4 3.0/2GB/9700Pro/Intel D875PBZ system, using Antec's Sonata, with the included 380W PSU. I'd been getting random lockups while on the desktop that seemed video card related (screen would become garbled, and a few seconds later I couldn't toggle num-lock.) Once or twice I sat down at my computer after it'd been idle for a bit, and as soon as I moved my mouse, the screen went bananas.
EDIT: I could play UT2004, 3dMark04, KoTOR, and other games with absolutely no lockups. The crashes always occurred while on the destkop.
All my DIMM slots are filled, but I ran Memtest overnight on the extended settings, and it reported no errors, so I don't think that was the cause.
I did two things after which the lockups stopped (knock on wood.) I dropped my 9700 Pro from 8X to 4X, and gave the RAM 4-4-4 timings, from the 2.5-3-3-8 reported by SPD ( I think. ) Since Memtest seemed to run fine, and the only other thing I did was lower the AGP speed. I figure since it's an Intel board that should be fairly stable, maybe I have a flaky/insufficient power supply. (Yes, the 9700 is plugged in using a floppy connector.) I have no clue if 8X requires more voltage; does anyone know, or have thoughts on what could have been causing my problems?
I'm not overclocking, and the D875PBZ has no AGP voltage options. I have two 7200 RPM drives, an old Plextor 12/10/32A, and an
Audigy 2 in the case. They're all plugged into an APC Back-UPS 800, with over/undervolt protection.
Thanks!
