Maybe memtest is not the best to test memory bandwidth, but when I looked at older xeon E3’s it seemed they had atleast twice that bandwidth. Around 20GB/s in the same test.
They do talk about having dual channel or even quad channel - and when I google around it doesn’t seem that this board has anything of the sort. Is this the source of my lackluster memory bandwidth?
Maybe its a bit too late, and my google-fu has failed me so I’ve missed something. Do any of you guys have a good explanation or a suggestion as to why the memory of my system seems to be “slow”?
The motherboard diagram shows the memory being connected to the CPU in pairs. Also when you start reading more about memory configuration Supermicro recommends installing memory in “kits of two” as it will “increase performance”. However they never mention dual channel, they do mention interleaving. So apparantly there is no support for dual/quad channel memory.
So the question I am left with now: Is dual/quad channel memory a consumer feature, which is not available to ECC? Or is it a limitation of the Xeon SoC / Supermicro board?
