Reason I ask is that I've got 2 GB Crucial Ballistix PC2-8500 paired with a 5000+ BE, and optimized default BIOS settings set DRAM voltage to 1.96 V and speed to 800 MHz. At these settings, memtest86 results come back error free. However, if I crank the voltage up to manufacturer's spec, which is 2.2 V, I get an error very quickly that halts testing.

800 MHz Crucial Ballistix is rated @ 2.2 V as well. Is it okay to run it undervolted, or is this just some artifact of memtest that I should ignore?



That 2.2 is the maximum voltage. I ran my ballistix tracers for months on 1.9v with 500 mhz @ 4-4-4-9 timing on a p-35. always use a fan also. errors @ the same speed but higher voltage indicates a serious lack of airflow. ram needs a good breeze over it to disapate the heat.
