does using different brands of memory on same motherboard cause any problems or performance issues? I ask this as I already have 512mb of 2700 ram(I have an Abit AT7(333mhz) board) and want to get another 512mb but wonder if I have to get the same brand(I currently have 512mb of corsair).
Are there also any problems using different speeds of ram ie 3200 together?(apart from not getting best of 3200 ram on a 333mhz board)
