Lately my old system with a 4870 512mb has been getting BSOD's with Memory_management error in games like Assassins creed 3, BF3, FarCry 3
so i wnet ahead and increased fan speed to 70%(waaaay to loud so i just turn up the vol. to hide it ) it seemed to take away the problem but only for a while then i decided to go back to stock still the problem persisted so i took it down to 850mhz default was 900mhz and the problem is well gone pretty much so i was wondering if the memory chips have degraded over time?
