I did a memory test by microsoft just for the heck of it and I failed the tests even though I did'nt think I had a memory problem. My memory reads properly in windows and Si Sandra and I don't have any problems though it seems. I score a 4155 3d Mark 03 test and don't have any problems with games or programs. Could this be because I lowered the timings? Then I noticed the memory test supported certain CPU's and AMD 64 was'nt one of them. Could that be why?
