I turned on my PC this morning and it gave me one long beep and three short ones, the signal for a memory problem. It then boots normally. World in Conflict benchmark performance dropped from 24fps to 14fps at 1680x1050, everything maxed out in DX10 mode. Experienced sharp performance drops in other games too. Windows Memory Diagnostic reported that I was having hardware problems.
I happen to have two spare sticks of similar make and specs to the problematic ones: a pair of Corsair XMS2 PC-6400 5-5-5-12 1GB modules. So I removed the two old sticks and put in these new ones. Windows Memory Diagnostic still reported hardware problems, but all my games are now performing normally. I gained the 10fps lost earlier in WiC back and played through a 8v8 MP match without a hitch. Blew through a couple of Lost Planet levels. Performance was normal.
But Windows Memory Diagnostic still reports that there's a hardware problem.
What's going on? Is it my mobo? Or do I really have four faulty sticks? If I keep on using my PC as it is, will there be problems in the long run?
EDIT: Just ran one pass of Memtest86. Found 7 errors. This is with the fresh-out-of-the-package pair, by the way. I'll run another pass on the old faulty set tonight.
