I have 2x 2666v3 and 2x 2618Lv3s. They'll be running in an SC X19DRI motherboard with 64GB of DDR4-2133. Here's the thing: the 2666v3 is an ES CPU, with stepping QSFC. That means the cores run at 2.9gHz, with all cores turboing to 3.2gHz. One core can boost to 3.4gHz. It does support a RAM speed of 2133mHz. It does not support hyperthreading, limiting them to a total of 20 usable cores. It is also an engineering sample. The 2618L is a retail chip, with retail stepping. It has a nominal clock speed of 2.3gHz, with a single core curbo of 3.4gHz. The rest of the cores will scale, with a maximum of 2.9gHz. Once they start to get loaded up, the turbo clock will drop accordingly. It only supports DDR4 1866. It does however support multithreading, giving me a total of 32 usable cores.
My application will be ESXi 6.5. All my VMs are sensitive to high clock speed generally speaking. Some will be multithreaded, but not all. 32 cores means I can run substantially more VMs. Of course, if I load the two CPUs up I will lose precious clock speed due to the 2618L's scaling turbo. The 2666v3s have a higher all-core turbo and RAM speed. At the same time they lack hyperthreading and the polished retail stepping. The 2618Ls consume considerably less energy as well. I already own both of these CPUs. Please instruct me how to proceed
