I have installed right now 2x1GB RAM, matched pair DDR2 800. Mobo supports higher speeds, but with the processor I have 800Mhz is the highest. I am planning to add 2x512 DDR2 667 as a matched pair.
What is the speed after this addition? Is it going to be 667 for all 4 memories, or the mobo is able to run two of them at 800 and the other two at 667?
assuming the final speed is going to be 667 for all memories, is this going to impact on the performance at a level where I can actually feel it? The pc runs as dedicated HTPC, no games. The video card is enough for HD tv decoding but definitely NOT suitable for decent games, anyway.
