View Full Version : Dimension c521 Memory Question

May 11th, 2011, 10:32 PM
i have a not-so-old dell dimension c521 that i want to upgrade to the max. i'm looking at ram, and i am curious, it shipped with a 32 bit OS, so it was originally capped at 4 Gb of ram. with a 64 bit OS/Processor, can i go higher? or is there a hardware limitation?

The maximum amount of RAM allowed should be a hardware limitation, so using a 64-bit OS shouldn't increase the max amount of RAM. According to crucial.com (http://www.crucial.com/store/listparts.aspx?model=Dimension%20C521&Cat=RAM), you can only have 4 GB of DDR2 memory, with a max of 1 GB in each slot.
