I'm using 4 DIMMs on two of my A64 systems, it works fine. However you do
want some extra margin if you are going to use four double sided DIMMs. If
you step the clock speed back a grade (DDR800 @[EMAIL PROTECTED]
667, DDR667 @[EMAIL PROTECTED]
533) you
should be fine. Which means that for an overclocked Core2 you'll want
DDR800 so that it can be run at an effective 600MHz (2 x 300Mhz).
