Hi all,

I want to add to the RAM in my Dell Precision 390.  The user manual notes "Memory Type" as 533-MHz and 667-MHz ECC and non-ECC DDR2 SDRAM. It also shows memory capacities as 512 MB, 1 GB, or 2 GB.

Does this mean that I definitely cannot use 800MHz DDR2 RAM and 4 GB DIMMs? Or are these specifications just recommendations and in fact the motherboard can handle the faster/larger RAM?

Thanks in advance for your help.
