Just completed my first build, all went fine, and the computer booted up fine, I have installed xp on it, but I am slightly worried about the cpu and the ram. The CPU is for some reason only running at 1290MHz when it is an xp 3000+ 333 FSB and the RAM is 400Mhz and it is only running at 100Mhz according to the bios. Here's the specs: Mobo: MSI K7N2 Delta-LSR 8xAGP DDR400 Nforce2 CPU: AMD Athlon XP3000+ (Barton) 333FSB 512kb L2 Cache RAM: Kingston 512MB DDR PC3200 400MHz CL3 Memory Module VC: Sapphire Radeon 9550 256MB DDR AGP8x HD: Western Digital Caviar SE 40Gb UIDE 100 7200rpm 8mb Cache I went into the bios and attempted to change the RAM Frequency, but if I change it above 100 the computer won't boot (gives me a lovely black screen). And I am not sure exactly why the Mobo doesn't detect the right speed CPU... As I say, it's my first build and maybe I am missing something obvious?? Anyone help me out here?
