I'm working on overclocking a Socket 939 Athlon X2 4400 (2.2 Ghz stock, 1 MB cache each core) and when I run the Stress Prime Orthos test to stress the CPU itself it's fine, but when I do it to stress the RAM I get an error.
Now, I previously had a single core Opteron 148 in this computer and it seemed pretty stable at the same RAM settings and at a much higher overclock than the 4400. The computer has 4 x 512 RAM in it.
Is it possible that the RAM is now undervolted because the 4400 is sucking up more voltage? The voltage readings on my computer show it as being about 0.05 V lower than where I have it set in the BIOS.
Should I up the RAM voltage? It's currently set at 2.8 V. Should I start playing around with the RAM timings? Currently at 2.5-3-3-7 and 2T with a divider of 133/200. (Current CPU overclock is 11 x 225.)
