Sorry to bring this thread back -- I've just upgraded from a single CPU to dual CPU's on my 4,1->5,1.
If I'm hoping to rock dual x5690's, is the consensus that 6x16GB RDIMMS would be the best configuration? I'm trying to optimize a bit for memory latency and single threaded performance, but still want ECC.
Are UDIMMS a viable option, or are they limited by costs or the maximum memory I could configure?
Thanks.
This thread listed some known good DIMM's part number. for cMP
