i7 8700K with 64GB Ram @3000MHz in dual channel mode .

Hi

I'm building a brand new PC for engineering simulation purposes. The main simulation software that I use is like a single or few thread, ram hungry monster.

For this, I think i7 8700K with 64GB ram would not be the best but a very good solution since 8700K comes first when single thread performance is the issue.

Intel ARK indicates the CPU is capable of 2666MHz DDR4. I know that DDR4 frequency could be pumped to 3000MHz but I have doubts whether the CPU handle that much memory with dual channel mode @3000MHz or not.

Summary: Will i7 8700K with 64GB DDR4 with dual channel @3000MHz bottleneck in terms of ram speed?

Setup would be like

MSI Z370 GAMING PRO CARBON AC
i7 8700K @Stock Freq
4x Kingston 16GB DDR4 3000MHz CL15 HyperX Predator
240mm Liquid Cooler(Cooler Master or Corsair)

Thanks in advance,

Ahmet

I would ask you to get DDR4-3200MHz ram kits as the minimum staple since the sweet spot for the platform is actually at 3200MHz and a little higher, provided you want to put in the hours and effort to find that sweet spot past 3200MHz. Since you are eyeing a Z370 chipset, you should be able to reach that spec with XMP enabled or even manually inputting the frequency and latencies.

You didn't mention the make and model of the PSU you're going for and the chassis. Overclocking will produce heat from the CPU(because of the memory controller and a little from the rams).

Thanks for the fast reply. Actually I don't want to push the limits because it will run very sensitive computing software for hours. That's why I remain CPU frequency stock. Since the software is highly memory sensitive, a little pump could help more than I expect.

BTW I plan to get Corsair RM1000i PSU and a mid range GPU(1070/1070Ti or something). With this setup, I expect it would pull around 600W.
