DIMMs are Crucial 512MB, DDR, 266Mhz, CL2.5, ECC I'm running 2.4.20 (Debian, or vanilla, didn't seem to matter) The only stable configuration I can seem to get is 1 CPU and 1 DIMM. Every other setup Cerberus just blows up in anywhere from 10 minutes to a little over 2 hrs. Sometimes I see an oops, other times it just stops dead and no interrupts are handled (caps lock doesn't turn on the little light on the keyboard). I saw a similar conversations in the archive about a setup similar to this and various solutions, one being to underclock the CPUs, suggesting, I guess that CPU heat is a problem (even though I never see an alarm out of lm_sensors). I did update the board to the latest BIOS (1009), that doesn't seem to have any effect. testing with Cerberus: 1 CPU/ 1 DIMM run all the time 2 CPU/ 1 DIMM might run for 3 hours 1 or 2 CPU with more than 1 DIMM, lucky to last 20 minutes, usually less. I have tried each of the four DIMMs individually, they all appear to be fine. So I'm wondering if anyone has any insight into what the problem might be. Is underclocking the chips all I can do? -- Dale Harris rodmur@maybe.org /.-)
