Yes!

I have considered this for almost half year. Its expensive for me. 1000euro. But right now I have to simulate many many OpenFOAM cases. Then I made a hard decision!!

This is my configuration:

i75820k
ddr4 4*4g

I wish this will speed it up!

BTW, 5820k has 6 cores(12 processors) or 6 processors (12 cores).?

It includes 6 physical cores and 12 threads. You may distribute your computational loads among 12 threads.

hoho, Thanks dude! Im always confused about the cores and threads, now its clear!

Best,

Just a piece of advice.

Hyperthreading doesn't really provide any benefit for CFD computation so I'd advise disabling it in your BIOS and just running with the 4 cores (leave 2 so you can do other things).

Hi bro, do u think I should overclocking my cpu?
I will switch hyperthreading off.:D

And u suggest use 4 cores, do u mean 4 cores with 8 threads?

Yeah, now its running. super fast! I distribute it 12 threads!
