OK, yesterday morning I moved the box outside, hooked it up with network and power. Outdoor temperature was -1C .
Temperature rose to about 6 in the afternoon, but the machine actually ran pretty stable throughout the day. I had one lockup which needed a hard reset, but I haven't been able to reproduce that.
Whilst running 4 x mprime, the temperatures as seen by sensors stabilised at this:
work System CPU temp3 Outdoor 4 mprime 39 51 81 5 4 mprime 35 50 80 6
So it's all about cooling. The interesting thing is - the machine uses the AMD supplied CPU heatsink and fan. It's got additional fans and heatsinks to improve the air/heat flow. How do I improve on the cooling without looking at water-cooling and such?
The first thing I always do is get rid of the AMD supplied fans. I've used Thermaltake type heatsinks and fans. I know that Coolermaster and Thermaltake make pretty good equipment for CPU cooling.
A fan will never bring the temp down to -1C. The mobo is bad and generates copious amounts of heat. There is one other possibility, the mobo "thinks" it is bad and somehow finds a way to shut down. If a bios upgrade does not change temp3 reading drastically, it is time for a new mobo. d.
How big is your case? Midtower, full tower?
Well - the system remains unstable and automatically reboots after a while, maybe 10-15mins, of running 4 x mprime. I've already got an RMA# so I think this board is going back after all.
Could be the problem.
