Well, I am having an interesting problem. I recently upgraded from 2GB of corsair xms memory to 4GB of Patriot Extreme Performance RAM. First off, I messed up by not changing the voltage to the proper level. At first I was running it at 1.9v (the manufacturer recommends 2.1-2.2). So, obviously I start getting weird problems, lots of crashing. I finally figure out the voltage is wrong and change it to 2.2v. Now, I use memtest86 and do 10 passes and no problems found. I completely wipe and re-install Win XP, followed by Vista 64-bit (on a different partition). So I have dual boot, XP on one HDD, Vista on another. Get Xp all updated and everything installed and it runs great. Only minor issue is in Age of Conan I get some graphical tearing (which could be a video driver thing, though I get no tearing in any other game). However, now i switch to vista. Vista (SP1 installed)keeps getting failures on updates, and major graphical issues when trying to play games. Also, it sometimes doesn't load into Vista (it will freeze). I did the sfc /scannow and find nothing corrupt in the vista files. When I do windows updates, the Superfetch service will stop running, which is what I think causes the failure. The only other errors in the event log is Volume Shadow Copy, which keeps getting errors and restarting.
So, before i changed RAM, no problems. Now I have new RAM (which to the best of my ability seems fine physically), yet Vista is unhappy. Any thoughts?
