First, I apologize if this gets too long. I'm sure some of you have read about my problems that I initially thought were due to my new OCZ memory. I'm posting here because I now think all the problems I've been having are due to my motherboard. Move the thread if it would be better elsewhere.
Components:
ASUS P4C800 Deluxe Rev 1.03, BIOS 1014
P4 2.8C SL6WJ Costa Rica
P4 2.8E SL79K Phillippines
2x512 Mushkin PC3200 LvII
2x512 OCZ PC3700 Gold Rev 2
Problem: (instability defined as errors in Prime95 ver 23.8.1 Blend torture test and/or FAH - both produce errors @ same settings even when other tests pass)
System loses stability above FSB 237-238 @ 5:4 & FSB 223-224 @ 1:1 regardless of CPU used, memory set used, dimm slots used, vcore (up to 1.65v 2.8C, up to 1.45v 2.8E), vdimm (2.85v max setting, not volt modded), vAGP (up to 1.7v) and PAT settings. Both CPUs run up to FSB 250 / 3.5GHz, but are very unstable. Mushkins start producing errors in Memtest86+ @ FSB 225, 2-3-2-6-8, PAT enabled - looser timings and PAT disabled had no effect. OCZs produce errors in Memtest86+ (tests 6 & 10) @ FSB 233, 2.5-3-3-7-4 (rated speed / timings), PAT disabled.
My guess: Because 2 CPUs & 2 sets of high quality memory fail at the same settings (FSB / ratio), I would guess this is MB related. Even though I'm on air, temps haven't been a problem. 2.8C - no higher than 41.5°C (DigitalDoc5+) @ 100% load. 2.8E - avg 41°C @ 100+% load w/ spikes to 50°C (MBM - reports higher than DigitalDoc for 2.8E). Chipset - no higher than 38°C @ 100% load (DigDoc).
Agree or disagree? Any advice would be greatly appreciated.
