I have a P4-3Ghz with HT and an MSI 865PE NEO-2 P MS-6728 Ver 2 (No D-bracket) 3.50 AMI BIOS. I have two sticks of Nanya 256MB dual channel DDR RAM (PC3200) 400MHz. If I added another two sticks in the other two spare DIMM slots (to give me 1gb of ram) - would the FSB still be 800Mhz and the RAM still run at 400Mhz or do you need *just* two sticks in order to get 800Mhz FSB with this CPU and this motherboard?
