Some time ago, I could OC my RAM to DDR2-800 and do some benchmarking with MAXXMEM and was fine, but after the benchmark I would clock to stock (DDR2-667) again, so I never used the RAM OCed except to benchmark as commented. The computer worked perfectly without hiccups when the RAM was OCed. Now I wanted to bench it and clocked it to DDR2-800 again and after starting Windows, lots of error windows popped out, programs crashing, assertion faults(?) drivers (sound) not loading, DLL library errors, etc. Prime95 failed instantly, and got a single BSOD (CACHE_MANAGER) when rebooting. Reverted to stock and all is fine again. But I underclocked to DDR2-400 in hope to "slow-down" the dying process if it's the case. My question is, is my RAM dying or it's simply a bit "worn"? Could I use the RAM at stock as normally or should I prepare my wallet to buy another RAM? Here is a SS of CPUZ, alongside Prime95 failing. Many thanks EDIT: I forgotten to mention, after restarting the computer, the POST halted and said entered to safe mode because a error or something but happened once.
