Ok I installed 2x1gb Crucial Ballistix DDR500 RAM but I'm running them @ DDR400. It's rated at 2.8V with 3-4-4-8 timings. Do I need to set the voltage to 2.8 even @ DDR400? And can someone please describe what each number is in the timings are. I know the 3 in 3-4-4-8 represents CAS Latency, what about 4-4-8? I really don't know what to set my memory in BIOS at. Thanks for taking the time to help.
