The saga is about to conclude. The Gigabyte motherboard GA-MA790FX-DS5 with an AMD Phenom quad-core is unstable under full load, period. I suspect the memory controller setup, but Gigabyte has been unable to reproduce (under Windows). Last week I purchased an MSI board (K9A2 CF) with slightly lower specs (primarily AMD790X instead of -FX chipset) - yesterday I installed it with the same components (cpu, psu, memory, disks etc.). Earlier this afternoon it completed a 24 hour burn-in run with mprime stresstests going at full throttle - showing no problems whatsoever. Right now it's running four copies of mprime plus a Kubuntu installation in Virtualbox, and a Firefox3 beta. (I'm browsing the net whilst waiting for Kubuntu to make some progress). IMO the Gigabyte board is faulty - I'll ask the dealer to take it back tomorrow. /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
