I have been doing some research on this site and some others in prepartion for putting together my own computer. I have most of the things chosen, and I am planning to buy the Gigabyte GA-8IHXP reviewed not long ago. However, the type of actualy mmeory to buy for it baffles me. it says pc1066, but is that actual megahertz at which it runs? or is it 166 mhz? the price grabber does not have any bandwidth option for 1066 memeory, even though it has one for 800. can anyone help me?
