I got a 6700K with a MSI Z270 Gaming M5 and a set of 2x8GB Kingston HyperX Fury 2666 CL15..
This is pretty cheap Micron RAM that's not very well known for clocking..

And no, frequency wise it's terrible. It will barely do 3000Mhz and needs like, 17-20-20-40 timings @ 1.30v to even be remotely stable.

However... I'm on 2666Mhz now with stock 1.20v and i keep lowering the timings and testing a bit with prime 28.7 8K FFT @ 12GB RAM and so far even on 1.20v it still runs "stable" on 13-16-16-35-1T. I'm going to try 13-15-15-33 now lol.. How much lower is the CL going to go on this kit before i have to smash volts into it.. Best thing is, VCCSA is also still on stock 1.05v lol..

As soon as i find the lowest Prime 8K 12GB stable timings i'm going for the HCI 200% run as well.
Shouldn't take all that long with 16GB.

EDIT: I'm on 75% with 12GB in HCI now (8 instances @ 1500) on 12-16-16-35-1T stock volts 1.20v. No errors yet.. Seems promising.. CL12 on DDR4-2666.. lol..

EDIT2: It hardlocked at 80% tongue.gif I'm trying 13-15-15-33-333-1T @ 1.20v now. (6 instances HCI @ 2000MB so i can actually watch youtube on the background). If this is stable i'll shoot for 12-14-14-30-300-1T with a bunch more voltage.

EDIT3: 2666 @ 13-15-15-33-333-1T 1.20v easily passed 230% @ 12GB.

Should I just send back the RAM? Or is it the CPU?

Status: FAIL - test discovered HW problems

(No OC..just RAM @3200C14)

Anything over like 2600 is considered OC'ed. Do you have Xmp on? Do a bios reset and test with everything auto. If your ram fails, try re-seating all of the sticks, and retest. If that fails then it's probably the ram sticks themselves.
You should always test your system at stock settings first to make sure none of the hardware is faulty.

I just kinda considered XMP to be stock blushsmiley.gif
(running HCI at stock...)

...

1000% no errors

2666 @ 12-14-14-30-300-1T 1.35v also stable. Still on stock 1.05v VCCSA.



8 instances @ 1500 each = 12GB tested to a little over 210%.

I can't really go any further since changing any of the primary timings besides CAS will cause almost instant errors and dropping the tRFC to anything below like, 280 will result in failure to even POST / boot. Voltage doesn't seem to help at all either in getting any lower.

I don't assume increasing VCCSA will help in this situation since frequency is still so low? (wierd how 2666 12-14-14 is stable but 3000 15-17-17 is pretty much instantly nuked in HCI..)

I'm going to try one more thing that i haven't tried yet... CL11...

EDIT: Even CL11 is stable?! Oh well.. CL10 wont even POST so that is out of the question but 2666 @ 11-14-14-30-300-1T 1.35v on a cheap it like this? lol..

@Jpmboy

What's that utility that shows the motherboard voltages you have set, while in Windows?

I don't recall and seem to have deleted it. frown.gif

Hey @KedarWolf

Thanks for helping me with a custom maxwell titan bios a few years back! I believe thats Asus turbo vcore you’re looking for to display the voltages in windows smile.gif

Btw...can you look for that memtweakit link you said ? It seems the version I have lets me see them but not change them...

On a different note...
Can you guys please explain to me how Eventual DRAM v...Boot DRAM v...and VTT v work on z170 ?
It seems I have them completely wrong...whenever I touch them and set on Manual I do more harm than good...
