Using memtest86 on dual core Opterons got a measurement of about 2200 Mbytes/second, I think, with DDR1 PC3200 ECC RAM.
I think you could get a lot of work done with a 750GB RAM (2 of these, or one coming later) and dualcore Opteron setup.
- mrb 10y agoDDR1 PC3200 single channel should give you 25.6 GB/s in theory.
- undersuit 10y agoIsn't the PC component an upper limit on performance of a DIMM? PC3200 means 3200MB/s. While a single DDR3 1600 PC12800 DIMM would max at a theoretical 12.8GB/s.

- mrb 10y agoErr I made a mistake, you are right. PCx means a limit of "x" per channel. My brain read PC3200 as "DDR-3200" ie. 3200 MT/s. High-end server CPUs such as Intel Broadwell support quad-channel DDR4-2400 PC19200 which is 76.8 GB/s, a lot more bandwidth than the Octane.
