Which Thunder model? K8S, K8S Pro, K8SR, K8W? I run a K8S Pro with dual 244s (couldn't find any 246s and the 248s were just too dear for me) and 2 GB ... and I started off with an Adaptec 2100S RAID, but had consistent panics when booting. Apparently the aac driver isn't exactly 64-bit clean. I switched to a used HP NetRAID 3Si (aka AMI MegaRAID 438), and the server has run beatifully since then. Now running an Opteron database server for our production web site! P.S. For best performance, I think you really want to run 4x 512 MB. Running with two DIMMs means either you only get 64-bit memory access (not 128-bit) or else you need to put both DIMMs into the CPU1 memory slots (which means CPU2 will have to access those through hypertransport).

Howdy all, I've just installed 5.2-RELEASE-AMD64 on a dual opteron 248 machine, with the following specs : Tyan Thunder Motherboard 2 x Opteron 248 2 x 1GB sticks PC 2700 ECC ram adaptec scsi raid card. raid 5 array + 1 hot spare. Motherboard has onboard video, dual intel gigabit nics (bge). The output from the dmesg can be found on www.snsonline.net/~sarge/amd64_dmesg.txt The last freeze I had it was a panic, but the majority of the time the machine completely locks up. Any help people can give me would be much appreciated, I can't even do a build world as it fails within 5 minutes of kicking off the buildworld.
