GRABibus Hi,
tested 2101 on my ASUS X99-Deluxe II.
My OC in signature is still stable, as with former Bios 1902 : Realbench 8 hours stress test passed, HCI Memtest 1000% passed and Aida64 Cache stress test 4 hours passed.
No issues so far.

ThrashZone Hi,
Dimm voltage I have it set to 1.36v just for kicks give it a little more than default 1.35v
Dimm temp is the only factor to dimm voltage it is wild how much after a point 0.010+- can make there

Didn't state the 2666c15-c16 timings they were loose as a goose typical for hynix and micron memory guess that is the real issue with x99 and memory.

That and broadwell-e bios shoots vccio cpu 1.05 voltage to 1.25v+- just because one bumped frequency past 2133 !!!
Haswell-e bios never did that crap most say don't exceed 1.15v.

dansi nice! perhaps you can try lower the voltages with newer bios i am getting really good ddr overclock on x99.
in 2015, no one ever thought you can get more than 2666 outta haswell-e memory.

ThrashZone Hi,
x99 just doesn't like hynix or probably micron memory either
Samsung b-die works very well 3200C14 at default timings 14-14-14-34

Where as 2666C15 is just pure garbage
I had some 2666C16 worked very well for the first couple years on x99 ran 2800 off xmp profile 2
Like a smuck I sold it for C15 thought it would be better wouldn't run 2666 reliably

This was impossible with early bios

managed to fix the hyperthreading sandbox bug by restarting windows update, thanks to rog forums member!

TK421 Latest version of the bios made overclocking for my X99 Deluxe worse.

Used to be able to hold 4.6/1.374v stable but now even at 1.38 the system is still not stable during regular use and stress testing.
