Hi all, Does anyone have any theories on which size RAM should go into which slot, eg. largest chips at the front to smallest chips at back or vice versa? We're heavy Photoshop users here and I've often wondered if I should be leaving the largest chips to the end of the slots so the OS can use the smaller chips and leave the grunt work of Photoshop to the larger chips or should it be vice versa. For the most part I've been installing them largest to smallest. This assumes that there is some sort of lag as info has to be retrieved from different chips, otherwise this is a moot point. Anyway, your thougts are most appreciated. Cheers, Cojcolds
