For xmas i recieved 2 new sticks of 3200 memory to replace my old 2100. I decided to pull out 'ol prime 95 to test the stability of my new ram overclock. However, when i start the "blend" stress test, i get CONSTANT HD thrashing, only 10% cpu usage and it takes well over 2 hours to finish one iteration. I finally worked around it by using the custom setting, but i wonder why this problem surfaced all of a sudden? Has anyone had this problem?
