Hello guys!

I have recently bought a brand new rig. Everything works fine, except for the RAM.

Motherboard: SABERTOOTH Z170 MARK 1
RAM: Kingston 16GB (4x4GB) DDR4 2400MHz CL12 XMP Predator (HX424C12PB2K4/16)

It works fine when i have only one stick installed, but anything more than that results in bios lockups if i stay too long,
and BSOD'S in windows.

The BSOD'S i'v been getting are these

PFN_LIST_CORRUPT
KMODE_EXCEPTION_NOT_HANDLED
MEMORY_MANAGEMENT
IRQL_NOT_LESS_OR_EQUAL

Now, i've run memtest86 and the windows memory diagnostic, and it reports no errors.
(Can't do a 4 sticks at once test, since the system locks, so tests are done with only one stick at a time)

I've been trying to find a solution on Tomshardware while i was waiting to get authenticated here, and they seem to lean towards
a BIOS update.

Either that, or the RAM is faulty, they say. (I honestly don't think there is anything wrong with the ram, it runs like a dream when i only use one stick)

Worth noting about the BIOS and the QVL is that while the RAM is included in the current QVL that's online, it's NOT included in the QVL that's in the manual.
The RAM was released in Swedish online stores only a couple of weeks ago.

Could it be that while quality memory, the older BIOS does not recognize it? It's Very low latency (cl12) 2400MHz memory that had no equal when i started looking for parts to pick.


I'm running windows 10 64bit, on a Skylake Intel i7 6700k, with a EVGA 980 ti HYBRID if it makes any difference in the world for this matter.

What do you guys think? Bad RAM or old BIOS?

Thanks in advance!

(One last random question. The sticks came as a kit of 4 sticks. However they came paired 2and2. the serial numbers end on 29/30 and 23/24.
Could it potentially make ANY difference for system stability if i installed 23/29 and 24/30 (or any other combination) or is it of no relevance as the sticks are identical, and even sold together?)

Hello Carazide, welcome to the ROG forum.

It shouldn't matter what slots the sticks go in as they were tested to work with each other.

A 6700k shouldn't have any trouble running that ram but seeing how it is, insert 1 stick and try these settings.

VCCIO - 1.15v - 1.20v
CPU System Agent voltage - 1.15v - 1.25v

F10 and enter to save and exit then power down and add one stick at a time and see if you can get all four sticks working.

You can also try X.M.P. profile 2.
