Last week I put together a new system:
Gigabyte GA-MA790FX-DS5 (BIOS F3 which includes the AMD patch). AMD Phenom 2.2GHz (quad-core) 4 x 1Gb Kingston KVR800D2N5/1G (on Gigabytes approved list). ATI Radeon X1650 graphics. 2 x Hitachi SATA disks. The usual stuff - DVD, CDRW, floppy.

Well, this system is highly unstable under high load. If I start 4 x mprime torture tests, it will automatically reboot in 30-40minutes.
To you who've been offering advice on this matter, here's the interim status:
As suggested, I upgraded the powersupply from the meagre 350W to 850W. Almost certainly overkill, but I didn't really want to play around with this for a long time, so I decided go for safe. Very nice powersupply too - Toughpower from Thermaltake. Well, unfortunately it didn't do much good - the system remains unstable at high load. In the meantime I have also raised the issue with Gigabyte, who have in fact been quite responsive. They sent me a beta-BIOS version to try out, which really got my hopes up. Didn't change anything though - system remains unstable at high load.
I feel pretty certain that this is a Gigabyte issue, hopefully they'll come up with an answer. After all, the problem is 100% reproducable.
Watch this space ...
/Per Jessen, Zürich PS: as a side-effect the new powersupply is _very_ quiet, which is _very_ pleasant.
