DDR2-667 and Conroe-L compatibility...I am so rusty!

You are a bit off. The RAM's rated speed is DDR2-800 which corresponds to 400MHz. If you were running a 1:1 ratio then you'd have to get your FSB up to 400MHz to run the RAM at its rated speed. Since your stock FSB is only 200MHz you'd have to OC your CPU quite a bit (3.2GHz) to get there. Another option is to run a mem multiplier or divider which just means you're running the RAM at a different ratio than 1:1. Your MoBo is automatically running w/ a 3:5 ratio (200FSB 3:5 333MHz RAM [DDR2-667 rating]). You can change this ratio in the BIOS (I assume...most MoBo's allow this and it is labeled differently in different BIOS's). If you set your ratio to 1:2 (200FSB 1:2 400MHz RAM [DDR2-800 rating]) then your RAM would be running at its rated speed.

Hi Jason4207,

My BIOS is currently set at:

DRAM frequency: 400Mhz
CPU FSB Frequency: 200Mhz

Am I good? Or am I still the village idiot, here?

You're running 1:1. Now OC that thing!
