Hi -- quick question: For a set (6) of reasonably modern Dell PowerEdge R740/740xd each with 128GB memory running VMware,
I'm thinking of upgrading them to 512GB - what's the price/performance sweet spot for memory these days? (32GB/64GB/128GB modules?)
Dell guy says to fill the slots - not opposed but would like a second opinion.

Thanks!

What memory do you have in them now? 12x 2Rx4 32GB RDIMM (maybe $50 per stick, depending on speed) would get you 1DPC on all 6 channels per processor, but only 384GB total. Or fill the slots with 32GB for twice that.
