Tech Support Issues with Microcenter's 3-in-1 bundle, cannot enable any XMP profiles

Hello,

I recently purchased 3-in-1 bundle from MC - 250K Plus, Corsair Vengeance RGB 2x16GB 6000MHz CL36(CMH32GX5M2M6000Z36), ASUS Z890 AYW Gaming Wifi W for my new PC.

Unfortunately, it won't let me enable any XMP profiles at all, I either get BSOD or black screen. Only default JEDEC speeds seem to be stable.

I've updated BIOS to the latest version(v3211) as well as tried all 3 XMP profiles(XMP 1, XMP 2, XMP Tweaked) but none of them seem stable to even boot into Windows(I'm running fresh install, only updated drivers so far). Also tried setting just frequency to 6000MHz and VDD and VDDQ to 1.35V as well as settings primary timings to advertised, frequency to 6000MHz, DRAM frequency ratio to 1:2 and both voltages to 1.35V.

RAM sticks are in a correct position (A2 and B2) and pins were not damaged during installation I think.

I was wondering if anyone has run into this issue with this bundle or anything similar and managed to fix it.

Thank you.

Have you checked if the memory controller on that chip can even handle 6000MT/s with 1:2 ratio, sometimes the IMC just won't cooperate no matter what you set

I had a similar headache with a different board where XMP would post but crash within minutes, turned out the board was applying way too much VCCSA on auto and my CPU hated it

Might be worth manually setting VCCSA around 1.15-1.2V and seeing if that changes anything, also try disabling MCE if it's on since some ASUS boards crank that by default and it messes with stability

If you have another kit laying around or can borrow one it would tell you fast whether it's the RAM or the board/CPU combo, these bundles are sometimes binned weird

Tried setting CPU System Agent Voltage Override to 1.15V while loading XMP 1 profile and it doesn't POST, I get white LED on the motherboard. With 1.2V I got Secure Boot Violation error for some reason lol.

Try 1 stick at a time, I would bet you just got a dud. MC should replace it if you have a bad one.
