I have just built my first computer.....it is running fine with the RAM speed at 300Mhz. And that is the problem!

POWER SUPPLY: 485W
MOTHERBOARD: Mach Speed N2PAP LITE nForce2 Socket A
CPU: AMD Athlon XP 3000+ 400Mhz
RAM: 2 x 512MB DDR PC3200 (400Mhz) - PNY OPTIMA Memory
VIDEO CARD: Asylum GeForce FX 5200 (256MB PCI Card)
OS: Windows XP PRO

The motherboard, CPU, and RAM, are all suppose to run at 400Mhz. I checked for BIOS updates, I have the latest version, downloaded utilities and check and tweaked the RAM's CAS Latency, precharge, RAS to CAS, and RAS active time. Call the motherboard manufacturer and test my first set of RAM that wouldn't run right, determined that one of the sticks was mislabeled at 333Mhz. Updated drivers for the motherboard itself. If the memory is set at 300 or 333 the processor will function at 400Mhz. If I set the memory to 400 the processor will only operate at 333 or below. Although 300Mhz makes the system more stable, less power down/restarts. One stick of 512 DDR400 (PC3200) will work fine at 400Mhz while running the CPU at 400Mhz. I am at a loss......that is why I bought the components, so my system will run at 400 all around. Please, any help would be appreciated at this point.

Thank you,
Chris.
