I recently had my DFI LanParty UT nF3 250Gb mobo recapped and am rebuilding it for possible use as a media system/DVR. The board has three 184-pin DDR slots and supports up to 3 GB of PC2700 (DDR333) memory, and also supports up to 2GB of PC3200 (DDR400) memory. I have both 3GB of DDR333 as well as 2GB of DDR400, hence I am able to max it out with either. So, is it more beneficial to use more of a slower RAM chip (i.e. DDR333) or less of a faster RAM chip (i.e. DDR400)? My gut tells me that it may be better to get more (3GB) of the slower RAM (DDR33), but I really don't know, and I'm looking for some guidance and reasons for your answers. Also, is there a way to test this without spending big bucks on some benchmark program? Thanks in advance.
