Question: Will an ULTRA DDR MEMORY 1024 MB PC3200 DDR 400MHz work on a Dell Dimension 3000? Details in the Memory part of the desecription of the 3000: Up to 1GB (dual channel) Shared1 DDR SDRAM at 400MHz for superior performance (Note: 400MHz memory performs at 333 MHz with 533 FSB processors). OK so the 1GB and 400Mhz part of the desciprion fits, but what is this "Shared" thing? Does it mean it only supports dual RAMs and single RAMs? Thanks.
