no, u actually insert 2 dimms in the first 2 slots from the cpu socket outward. I know it makes no sence cuz of the color codes, but the manual and website actually state it. I have this board with a winchester 3500 and 2 GB kingston hyperx (2x1GB) and it runs freeking nice. I haven't had any problems. o, and if yer gonna get 2GB and want it in dual channel then i recomend the hyper x, its the only one i could find that had decent timings. (2.5,3,3,7) this is 3200 btw. I saw the manual saying no to 4GB DDR400, but i'm sure it will run at 400 with4gb if ya want, i mean its designed for overclocking to an exttent. and thats not much of an increase. o, another fyi on the mem i bought found out afterwards the timings advertised are for a lower speed than 400 - think it said 266 - but again its not a big problem to set the timings to the advertised ones. won't cause major problems if any at all. I was browsing these forums looking for a post made months ago about this board having probs with antec PSUs. another fyi. haven't found the post yet. I use an Allied, and no problems that i can see. I have to admit i've read posts from people having problems with MSI boards, but hopefully i won't have any since havn't yet.
