Well over the weekend I did the following:
Swapped the PSU my noisy supermicro server-grade PSU - no changes
Moved the video card to a different slot - no changes
uninstalled video drivers - no changes
put in my old Asus EN6800 card -no changes
moved the old card to the 2nd PCIe slot - no changes
ran with 1 stick of ram - no changes
swapped the memory sticks - no changes
I also noticed the problems seem to be behaving like a heat issue. From a cold start, [email protected]
will run for an hour or so, then reboot. after that, the reboots come much more frequently until I run out of paitence and just shut the thing off.
I fiddled with the memory timings a little. but I know very little about what to do and what not to do with respect to setting up memory timings.
I think I breifly tried underclocking the CPU at 2.8ghz -- but again no change in behavior.
the memory is listed as 1066 but i want to run it at 800 -- and thats the way the system was shipped to me.
im running win XP with SP2.
As for the cooling - where is the SB and/or NB on the motherboard? how do I tell one from the other? where does one find acceptable temps? The monitoring tools have a "chipset" temprature which sets steady at 40-41c no matter what im doing.
There are 3 extra heatsinks on the motherboard. one with a tiny black heat sink. and 2 that are connected via a heatpipe near the cpu socket. None of them seem to get real warm while the system is running. I can easly grab hold with no fear of burning.
I can try 3dmark and/or orthos to see what happens. I assume they are freely downloadable?
