Does memory speed impact Xeon E3-1270 v6 performance?

[Lil'John]

Title states it.

I know it has an impact on normal cpus.

From what I've seen and read, dual channel CPUs tend to be more sensitive to memory speed than say quad channel CPUs, due to having less cache.

Implying this isn't a normal CPU?

Implying it is more of a workstation CPU and not a consumer CPU. You know, features that professionals want like ECC memory.

Any other words of wisdom to add to this thread aside from a nit-pick?

My point is it's still the same core technology. In this case it's a "normal" Kaby Lake CPU with a little bit of extra features. If you know the "normal" CPU's impact performance, then you have the answer to your question.

It's basically a standard Kaby Lake CPU with ECC support, and no IGP. A little faster base than an i7-7700, with a slightly higher TDP to match.

If the board allows the memory to run faster, it will perform better, just like any KL chip. They like memory bandwidth.

Thank you for the information.

I am looking at the Supermicro X11SSZ-TLN4F:

It allows me memory speeds from 2166 to 2666... or $200 to $240 per 16GB.

My intention is to max it out(64GB) for file server, media server, and camera recording duties.

I suspect that for those duties, you will not be able to notice any difference in performance from 2133 to 2666 unless you benchmark it, but I tend to think of 2133 as "slow" and personally would get 2400 minimum.

That said, if the 2666 is not much more expensive...
