I just got a new system and the motherboard constantly gives three beeps on boot, which according to the manual is a main memory read/write error. To save you looking it up in my profile, it's an ASUS P4C800-E Deluxe motherboard, and the memory is Corsair's 1024MB TwinX, DDR 400, PC3700 RAM (four 512MB chips totalling 2.0 Gig). I can't stop it doing it, the memory tests out fine, and it even does it if I install EACH memory chip separately - I can't believe they are ALL faulty! Is it because the speed is too high for the board? Should I go into the bios and "tone it down" a bit - if so some kind soul will have to give me the *****'s guide on how to do it. I've tried Tech Service at asus on firstname.lastname@example.org, but the email just gets bounced as undeliverable (very helpful - NOT). Heeeeelp!!
