DIMM3 memory

by c2c--2008 / April 8, 2009 1:52 AM PDT

I read that DIMM3 memory is, or is soon going to be, available, and faster than DIMM2.
Would an update be worthwhile?
Would that be a transparent switchout for DIMM2, or are older motherboards not forward compatible?

Check specs

You have to review the specs of your current system or mtrbd. to see if it supports DIMM3. If not, then you need a true compatible ready DIMM3 mtrbd. Now, some systems that are DIMM3 will be compatible to older DIMM2. Of course all ram modules do need to similar types/class in or to run. Its best not to mix such ram DIMM2 with DIMM3 but it can be done provided the mtrbd. supports that. And is usually the case it will run at the slowest and lower class rating. I won't expect a bios update to change anything here if any for the DIMMx case. DIMM3 is already here and expect a premium price if you rush out now. As for speed difference or any benefit, yes its there but not a wholesale increase in any big way. Of course, any increase is better than none at all and this is a solid increase.

i assume you mean ddr3, not dimm3

ddr3 is the latest memory standard for desktop PCs and has been available for the past couple of years. it's finally fallen in price to the point that its only a bit more expensive than ddr2 (4gb ddr2-800 is about $40 but 4gb ddr3-1333 is about $60). ddr2 tops out around ddr2-1066 (officially) but ddr3 is already at ddr3-1600 and is designed to hit speeds above ddr3-2000.

ddr3 does require a new motherboard. there's no reason to upgrade unless you plan on a new cpu also. intel core i7 currently uses ddr3 memory only.
