G.Skill TridentZ DDR4 3200 won't XMP

Hi guys,

today all of the parts for my new PC arrived, namely an i7 6700k, GTX 980ti STRIX, MSI Z170a Gaming M7, G.Skill TridentZ DDR 3200 4x8GB (quad kit).

My problem is that when I set the RAM on the suggested XMP profile 3200, 1.35V, 16-18-18-38, it reboots, gives me 30 secs of blackscreen, and then comes back up telling me that the OC failed and that it reverted the settings. I also tried lower XMP settings, and the only one working besides 2133 stock is 2400 which I use right now.

I have not found out how I can manually set up the voltage and such, because most of the RAM settings keep locked even in advanced expert (lol) mode. It is kind of annoying that I payed for the high-end RAM where cheaper would have come to the same frequency. I thought that buying sticks specifically made for a certain frequency would definitely work with the XMP profile...

If anyone has an idea on how to solve this, it would be greatly appreciated.

Cheers,

Mc

P.S.: I also bought a Corsair H110i GTX aio water thingy, and I connected it with that puny 1 on 3 pin cable to the mobo, as well as the two supplied fans with their 4 pins onto the pump connector, as well as sata power. The lowest RPM they get is like 900, which is kind of loud. Is it reasonable to stick both 4pin fans onto the CPU_FAN header on the mobo, and the pump onto sysfan, to reduce the noise in idle?

Okay, I'm gonna try that as soon as I get home tomorrow. Is there any guide or checklist to follow when OCing RAM in general? And should I leave XMP enabled when I OC it? I am not quite sure if the MSI mobo lets me access memory specs outside of XMP or "Memory try it"...

I was able to boot after setting the timings given in Memory-Z manually, setting the multiplier to 1.33 and adapting the frequency to the according 3200 multiplication. I also set the Command Rate to 2 and upped the System Agend Voltage (CPU SA) from 1.056 to 1.060V.

Doing stability tests now, hope it works. Will post results. Thanks for your help!

Cheers

It seems to be stable, I let SuperPi run several times as well as Memtest in Windows for 400% coverage and previously Memtest86 bootable to check for errors, everything is okay. Thanks again for helping me! :)

Hey McFettnippel.
Could you share the settings on your BIOS (or a screenshot) that fixed your issue?
(If there is something more that those you already mentioned..)
I have the same setup and can't get 4 dimms to work at 3200..

Thanks in advance!

Hey,

it worked for a short period of time, but if I have any kind of OC on my RAM, after 3-5 days I get a OC failed warning and my settings get reset. I have yet to find a solution to this, even with the newest BIOS beta updates.

This problem seems to be known though, as I have searched many forums and found several people describing similar problems, across different brands utilizing the Z170 chipset, regardless of RAM manufacturer.

Sorry that I can't help you out here, but I have arranged myself with a stable 4.6 OC on my CPU and not OCing my memory at the moment. It didn't make any difference in performance, at all.

It may come in again when I buy my second 980ti next month; I read that 2133 would take around 5% of your overall performance and bottleneck your GPUs, you should get around 2400 at least.

I am a little disappointed though as I thought that it should be possible to reach the desired frequency on that highly priced RAM, especially with a state-of-the-art motherboard and CPU.

Cheers
