I'm looking to build a Xeon workstation using a Xeon E5 2686 V3. It's to be used in a C++ environment to run real-time computations. I had previously been using an i7 4790k, but it simply wasn't cutting it.
I'm trying to understand what sort of performance impact I might get from an un-optimal ram configuration.
I currently have an Asrock X99 Extreme 3, which only has 4 DIMM slots.
I was planning to use 64gb total DDR4, so 4x 16gb modules at 2133mhz, however looking at the memory controller specs for the 2686V3 I see that that the DIMMs per channel is 3*, and I'm wondering if my planned configuration is going to cause any sort of bottleneck?
Does this mean an optional configuration would be a board with that has 12 Dimm slots, occupied by twelve modules in quad-channel configuration?
And
Would there be a performance difference between running 64gb DDR4 @ 2133mhz configured in a motherboard with 8 DDR4 DIMM slots, each occupied by 8gb modules vs a motherboard with 4 DDR4 DIMM slots, each occupied by 16gb modules ?
Thanks
