would that memory even work for this motherboard? There isn't any approved 1100 on the QVL.
I do plan on doing a small overclock of the processor. Do you think i should just go for 800mhz ram? would there be any increase in gaming performance to go with the 1066 or would the 800 preform about the same
4 or 8 GB of that RAM will work fine. A maximum of 3.2 GB will show up in XP, but that's enough for gaming and office applications. Get 8 GB if you'll use it, e.g., you'll run VMware Workstation and several VMs or you'll run applications that take advantage of more memory. As tested by Tom's, games don't need more than 3 GB. If you get 8 GB, also get Vista 64 to take advantage of it.
