There in his last picture he has 96 cores. so the previous picture with 48 cores, and the benchmarks could be with one cpu active, or with 2 cpu, but on each one only half the cores active! But i was probably just to paranoid. I wrote with him, and he seems an honest seller. But it all does not matter so much any more. The many screenshots of you and others, made it very clear that the low scores were not inherent cpu issue but just setup or memory issue. Thanks for clearing that up.
But now, since low performance can be related to memory, i have some questions about memory.
You write that these Xeons have 4 dual channels memory controllers.
Does that mean i need to buy a minimum 8 RDIMMS to avoid any significant performance penalties?
Or would 4 RDIMMS with dual rank also be OK?
My preference would be 2 RDIMMS , such that i can expand later, but based on what i saw fear this would initially limit performance.
Also there are many 2Rx4 RDIMMS, since the width is only half compared to 2Rx8, would that give signifficant performance penalties?
With performance penalty, i mean roughly differences larger than say 20% from optimal speed assuming the workload is large but fits in memory. I am sort of on a budget, and i want to avoid to buy a silly memory setup.
