Question RAM OC Question

[Victorpresti]

Hello, my dumbass bought the wrong memory sticks, a fairly long time ago so sending it back isn't an option. I have a different problem with my MOBO, so I didn't realize being unable to turn on XMP had to do with the stick itself, thought was just another MOBO issue.

The relevant bits are:

I9-9900KF
z370m

Now the memory is a Corsair Vengeance RGB Pro 3600mhz. I've bought the AMD Model tho, Z.
Since XMP won't work, I've tried overclocking it manually. Changed the memory setting on the MOBO from 'normal' to 'relax OC', set the RAM up to 3600mhz and the voltage was set to 1.35v.
It worked. At first. Until I tried to run a game and it started stuttering and I immediately knew it was the memory overclock. Is it just not possible? Did I set anything wrong? Should I try a lower frequency on the RAM?

Thanks.

Mm,

Z370M Aorus Gaming
CMW16GX4M2Z3600C18 is the Corsair Vengance RGB Pro Model
Nvidia 2060 Super
I9 9900KF.

The MOBO has an issue where only the rightmost RAM slots work, #2 and #4. Could be a pin on the CPU or something else, but I don't think it's relevant to the OC issue because my old RAM, a G-Skill Flare X 3200mhz, worked fine with XMP.

DxDiag just in case.
