I'm buying a poweredge T310 Intel® Xeon® X3430, 2.4 GHz, 8M Cache, Turbo, for memory should I get:

8GB Memory (4x2GB), 1333MHz, Dual Ranked RDIMM or 16GB Memory (4x4GB), 800MHz, Quad Ranked RDIMM

How would the memory bus speed play a role in this configuration?

I cannot urge you more strongly - GET THE X3440 FOR THE EXTRA £40/$WHATEVER!!! - the X3430 is the only bin of that chip that has hyperthreading switched off - it's really worth the extra.

Now your question - get neither the 8GB nor the 16GB options - go for the 12GB - Nehalem's are optimised for blocks of 3 memory modules at a time (i.e 3 x 4GB). This configuration will benefit you way more that actual chip speed.

thanks for the recommendation, would X3470 be better than X3440? –  jon Oct 6 '09 at 20:49
    
faster yes, but a LOT more expensive - not good value, the X3440 is the 'sweet-spot' but don't be afraid to go to the X3450 if you think you'll benefit from the extra grunt - just don't go for the X3430 ok :) –  Chopper3 Oct 6 '09 at 20:53

you're right, but it's the 'divide by 3 not 3' rule that's key - so yes, yes you will benefit. –  Chopper3 Oct 6 '09 at 21:13

'3 not 2' I meant of course ;) –  Chopper3 Oct 6 '09 at 21:29
