I have already red other topics about memory issues with this particular motherboard. but my issue seems a bit different, thus I decided to open a new topic. I'm using the Asus Z170 Gene (bios 1402), Intel i5 6600K (no OC) and Corsair 4x4GB 2400MHz ram (CMK16GX4M4A2400C14).
the motherboard and the ram are both in each others QVL lists so I expected them to work flawlessly. the cpu, motherboard and ram combo is about 2 months old and I'm facing some random stability issues. the range goes from a freeze to a BSOD, always random and not really reproducible.
I've been investigating that together with the great guys over at "tenforums" but was not able to find the real cause. suspecting a driver issue I performed a clean install of my Windows 10 Pro so drivers should not be a problem anymore. only a minimum of the only needed driver are cleanly installed: vga, audio and chipset (all up to date).
what I realize is that I never have a BSOD or freeze while running my rams on auto settings. as soon as switch the rams to XMP and run them on 2400MHZ (instead of 2133MHz) I get random issues. to be clear I never have issues to boot the system, the issues come later on and are not predictable.
additionally while troubleshooting the BSODs I ran a Memtest on the rams for more than 8 loops with no errors. so there seems to be no physical issue with the rams but still XMP causes problems.
what's the problem with that motherboard, why is an overclocker motherboard not able to run 2400MHz ram on XMP?
the rams supports even 2666MHz on XMP (second profile) and the motherboard is advertised even with speeds up to 3800MHz.
I just don't get what's the bottleneck here, what's causing the issue?!
I appreciate any help I can get, especially by users of the same motherboard.
I see your ram is the corsair vengeance LPX and in the description it says it's optimized for x99 boards. I know there can be some confusion over DDR4 memory some say compatible with x99, some say compatible with x99 and z170, some say compatible with z170.
I think I would try a ram kit that's specifically designed for z170.
that was exactly what I thought while I was searching for ram and ended up at Corsair.
just to make sure I checked the Asus Z170 Gene Dram QVL and saw this:
then I started Corsair's official Memory Finder just to find this:
so one of them, Corsair or Asus, is really messing around but which one?!
unfortunately I don't have a spare ram I can play with, neither a friend of mine has one I could borrow. so I'll have to buy one just to be able to test, additionally there is not much choice at that speed in the motherboard QVL list.
OK they have listed on there the blue kit and it says for x99 boards too, see what I mean about the confusion? If Asus says it will work then it should work but Corsair says it's for x99, they don't mention z170. When looking at ram always go by the ram manufacturers QVL list.
I still would try another ram kit designed for z170.
can you attach a screenshot of your search results please?
I wonder why I'm getting different result for the same search.
choosing 16GB (4x4GB) in the results always leads me to the result I posted as picture nr. 3 previously. being CMK16GX4M4A2400C14, CMK16GX4M4A2400C14R and CMK16GX4M4A2400C14B. and all three kits are obviosly X99 only, still being suggested for the Z170 Gene.
but choosing 16GB (2x8GB) leads to kits that are X99 and X100 compatible.
I did have CMK16GX4M2A2133C13 before on my Maximus Viii hero motherboard and did have harlocks with that memory. After i did change to G.skill f4-2400C15D-16GVR there has been no problems. I think there is a problem with vengeance ram from corsair and the new Z170 from asus.
