Memtest86+ errors - Mobo, cpu or ram after all?

[Fauris]

Hello, I hope I've  posted this in the right section.

 

As the title states - there is a problem, but I'd like to clear up some confusion that is going on here for me, if possible by someone more experienced in this matter

So in short:

Memtest fails every time at test #7, but it happens on 2 different RAM modules while tested separately, they are both of the same kit. Always exactly 32 errors - never while going trough the first pass, doesn't matter what slot on the motherboard I use.1st Slot(closest to cpu) seems to be dead, but I'm not entirely sure, but system won't boot if there's ram stick in it.

Normally I'd be saying "the motherboard's done for" even for the 1 slot for ram that seems to be dead. BUT, what confuses me is the fact that every time, while hyper-threading is on the test finds the 32 errors with/by the "CPU:2", when i tried to run the test without HT in multi core mode, the test froze at about 2 minute mark every time. I've not yet tested single thread mode on memtest, will to that later today.

So could it be the motherboard? Or can a cpu cause a single DIMM slot to not function entirely? Or I am really that unlucky with ram? 

The system specs:

cpu: i7-6700k

mobo: Asus Z170-A

Ram: 16gb CMK16GX4M2B3200C16

PSU: HX850i

HDD: Seagate 2TB Barracuda

SSD: Samsung 850 evo

 

Yes I know the ram is not in the list of officially supported modules by the board, but it's not the first time I've done something like that, but I've never had problems before.

Thanks in advance.

If you used MemTest, then it's telling you the RAM is faulty. Especially considering it did the same thing no matter which slot you put it in. And you just happen to be lucky enough to have two dead modules. I would RMA, even return it, and get something that's on the official supported list.

 

Oh, make sure you have XMP enabled in the BIOS, then take a pass at it again.
