Trying to find out which ram, 2 x 256 DDR Mushkin 2-2-2 or 1 x 512 DDR Mushkin 2-3-3 , would perform the best. I understand the 2-2-2 would be faster but doesn't it slow down/have more trouble when using additional slots? Also I have read some mbs have issues with a 512mb stick. Any experience with this or advice is most appreciated. The mb is a Gigabyte GA-7DX and will be running WinXP pro and Win98se in dual boot, don't quite trust XP entirely yet as some progs don't work.
