I need some help. I have an M2N-SLI MB bios 5001 running an AMD Phenom IIX4 940 with 4 X 1GB OCZ800 DDR2 dimms. I have a degraded Raid 1 array (that I'll deal with later) a 320GB system disk and a dvd/rw drive. Originally, I had a Palit GT240 video card (non-sli). Recently, I replace my Palit with an EVGA GT560ti. This all powered by a Thermaltake TR2-600w PSU. The machine awhile back had a problem with usb port problem (okay I just moved some connectors around and forgot about it). Now though the machine frequently reboots when under any kind of load or I'll come in in the morning and find it sitting at the login screen.
When I first power on the machine I hear a revving sound from one of the fans. (Palit) Always heard this from the Palit? dmesg always showed a message regarding mal-non-functioning cpu thermal sensor . Okay I ignored that for maybe too long. but the machine never displayed any issues before and it has run mostly 24/7.
hardware specs in bios shows the voltages as follows:
I have been doing some troubleshooting:
The every ram stick fails in any slot running memtest at test 7 and it is massive thousands if I go away for awhile. I have disconnected every non-essential device and still the sam. I went to the asus websit:
and input the specs and came up with a minimum of an 800 psu or so.
I want to know if there is a definite answer here. Did I slowly cook my MB running under powered and inturn toasted the RAM? Or Just my MB? or just the RAM. I did try a smaller known good power supply got the same memory errors from memtest. So I don't have alot of money to throw around and I want to be able to use my SLI ready card. What recommendations do u my fellow (k)ubuntu hardware gurus recommend?
btw I have done some internet research (Toms Hardware) and no problem quite matchs mine
