My computer reboots itself in windows and drops out of programs. Is my memory bad? I have pc2700 ram. Running memtest says mem is bad and needs replaced when I have mem frequency chosen by SPD (166 freq). When set to auto it sets freq at 133 and memtest doesn't find any errors. I tried moving the 2 sticks of ram to different slots with same results. I have 2 sticks of Crucial totaling 512. Athlon XP2100. No overclocking. Even though my processor is 133 the memory should still work at 166 right? Thanks for any help or ideas.
