I just upgraded to a Core 2 Duo 2.13Ghz, and 2 gigs of DDR 2 667MHz ram. It is showing up as 533MHz. I use a Jetway 775GT1-Loge board. Please help if you can.
read the installing ram and troubleshooting guide in the guides forum.
Your RAM will only run as fast as the slowest stick and the fastest setting your motherboard allows. Certain brands will always run at certain rates on some motherboards if you don't use recommended brands.
