Ok this is my problem everything else works fine, in bios it wont let me set the memory to 400mhz or 1/1 with the FSB so its always running at 333mhz,

my computer is a AMD 64 3000+ 2x 512 sticks of muskin lvl 2 ram 400mhz 2-2-2-5

the board is sposed to support 400 mhz anyone have a suggestion.

i have updated the bios

using all current drivers.

ok i have tried a couple things when i only put one stick of ram in the mb it runs at 400mhz if i add a stick it drops to 333mhz, i took out the muskin and tried this with a pair of corsair sticks did the same exact thing except dropped to 266mhz this is pretty weird anyone know why this is doin this
??
 
It sounds like the RAM timings might be too tight (2-2-2-5). If possible with your BIOS relax them to, say, 2-3-3-8 or 2.5-3-3-8. Make sure you have the latest BIOS for your mobo installed. Just because the RAM maufacturer programmed the RAMs to run at 2-2-2-5 doesn't mean that all or even most sytems can actually run it at that speed. Download and burn to a CD Memtest86 to thoroughly test the RAM speed settings. You'll need a CD burning program like Nero, Roxio or CDBurnerXP Pro to burn an ISO file image to a CD. Be sure that your BIOS is set up to try to boot from the optical drive before it tries to boot from the hard drive.
 
tried that doesnt do a damn thing, the ram isnt the problem its been tested its gotta be the board bios has been updated also
 
Yes, I believe the RAM is good, too, but that doesn't mean that it will run in your system. You may have to slow down the timings even more to get it to work at all in your particular motherboard. Often enough particular models of RAM are just incompatible with some motherboards. You may end up having to return the RAM or the motherboard for another model and/or manufacturer to get something that works. Look at the manufacturer's web site for RAM that has been qualified for your motherboard.
