I just recently build a dual AMD system with the following configuration:
Motherboard: K7D Master (no LAN)
CPUs: 2 XP1800+ MP modded & overclocked to 17*133
H/S: Two SK7 with Sunon fans (39CFM)
Memory: 1 stick of non buffered Buffalo Technologies 512M (PC3200)
Hard Drive: 80 Gb Western Digital (8Mb)
16 x DVD ROM
48x12x48 CDRW Burner
P/S: Channel Well 420W
Video Card: ATI 9100
5 x 80mm case fans (2 Sunon in the front, two Antec on the back and one Sunbeam on the side panel)
I have tested system stability with various utilities: Sandra Burn In Test, CPU Stability, 3D Mark2001 loop. I also have run two instances of Prime95 for more than 24 hours without any problem. The Vcore is now at 1.65V. At idle, CPU0 is at 42C and CPU1 is at 47C. Under full load, CPU0 is at 48C and CPU1 is at 54C. Even though the system is stable, I got a problem. One or two times out of ten the system will not cold boot. I have to switch off the P/S. Then switch it on, wait between 5 to 10 seconds and then it will boot properly. I have asked question in the SMP section and they think that I may not have adequate P/S to power my system. I have several options:
1) Keep the Channel Well. I am not convinced that this is a P/S problem (people at 2cpu.com has the same problem with various dual AMD M/B and 550w antec P/S)
2) Buy a new Fortron/Sparkle P/S from newegg. Should I buy the 530w or the 460w? The Fortron 530w seems to have more power but the 460w was designed for dual AMD M/B (as indicated in its description). The prices of the two units are pretty much the same.
