G.Skill F4-4000C18Q-32GTZSW & ASUS Maximus IX Hero motherboard

Hello all,

I have had this memory since early July and have not been able to get it running steady at 4000Mhz.

Let me start by saying it Runs Perfectly at XPS @ 3866MHz

I have tried:
The newest ASUS BIOS 1009
Extreme tuning
Dram voltage 1.38 and even 1.4 once
CPU System Agent as high as 1.33750 voltage
CPU VCCIO voltage as high as 1.33750
Maximus Tweak Mode both 1 & 2

I can get this RAM to run 4000MHz for only a few hours and then the nice blue screen.

My system spec are as follows in attached picture

If anyone has this setup and has gotten them to run at the rated 4000Mhz please reply how.

Thank you

CPU may not be capable, only few can achieve 3866+

The CPU is Intel i7 7700K The best at the time for that motherboard. But you may be correct. At least it runs flawless at 3866 MHz.
