Asus Z170 Gene strange memory issues...

hi guys,

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.

note:
for those interested hier is the link to my BSOD troubleshooting.

Ok there were actually 16 kits that came up, I didn't look at the other three pages but I have all 16 kits here that came up and I will post them for you.

Give me a minute I thought there were only four kits but there are twenty 4x4GB kits, I will post them all.

it would be enough to choose 2400MHz at the left bottom as I don't need higher speed rated rams.

got it, I see only the very last 3 kits as I selected the 2400MHz filter on the left side.

fact is that indeed the Memory Finder suggest this ram although it's "only" X99 optimized but not Z170.

so the only choice I have is either use it on auto or sell it second hand and buy a new kit. 😞

There you have it and come to think of it I remember another member having problems with the vengeance LPX on z170 too. It might be best to sell it and try another kit. G.Skill trident Z is specifically for z170. You have the 6600k which is an i5. The i7's have a stronger memory controller than the i5's so don't get too carried away. You could go with 16GB of 3000MHz and it's reasonably priced.

2x8GB will put less strain on the cpu's Integrated memory Controller.

16GB Trident Z 3000MHz

@TheRiwen
that's what I'm starting to think as well, the kit you had is stated as X99 and Z170 compatible.
if this still doesn't guarantee stability what else!?

@Nate152
maybe you are right and I should look for another brand.
I'm still curious though what Corsair responds to my topic over at their forum.

Since most RAM issues seem to be with Corsair + Z170 and there's a little misconception about which is designed for what I'd thought to ask G.Skill. This what they said:

Dear Customer,

The only difference of design between Z170/X99 is test platform, to pass all compatibility tests with different platforms.

However, please kindly check our QVL for the compatible frequency/timing as following:

http://www.gskill.com/en/configurator?manu=29&chip=2276&model=2292

Also, you can use same SPEC of memory kit as QVL, which means you can use same SPEC of TridentZ/RipjawsV to replace it, on the above link.

And you’re welcome to contact with our sales department to confrim about the out of stock items.

Best Regards

It seems designed for relates to the heat spreaders only. Having said that, I do believe that Corsair dropped the ball here, which they denied vividly upon my asking. But you can't argue with so many having these issues. G.Skill all the way I'd say!

that's good to know The F34R Channel, thanks for sharing the info.

what's your experience with your Vengeance LPX?

according to the explanation in the mail I don't see why my CMK16GX4M4A2400C14 should not work properly at XMP.
most kits of same type have similar specs across the brands, tested speed 2400MHz and SPD of 2133MHz at 1.2V.
what mostly changes is the timing, although not really significantly.

fact is, it does not work with no obvious reason - maybe CL14 is a bit too agressive, no idea to be honest.

@sahafiec

Try some other memory and not corsair.
Dont no how the return policy is you country but in denmark we have 14 days return policy on items we get on the internet.

Remember that XMP is not always guaranteed to work; it depends on the IMC on the CPU really. Set everything manually, forget about XMP.

My experiences...well the word on that isn't in yet. Have been issues for months that are difficult to narrow down so I'm slowly replacing components...RAM is next if neccesary...then the board...then I kill myself. G.Skill it'll be for me then: http://www.gskill.com/en/product/f4-3000c15d-16gtz I'm really a G.Skill/Kingston guy, never had any issues with either. This is my first Corsair and I don't know...
