memory 16g ram runs at 3200, but 32g at 3200 bootloops

[Burkham]

So I have a 9900k, Asus strix Z-390-F, Asus strix 1080ti, 16g 3200 dominator platinum (2x8g). Ran like a dream. Ran at XMPII.  However, I purchased the same exact memory and installed it, now ram doesn't run over 2133...when I enable XMP computer goes into bootloops.

enable XMP

so disable XMP and be happy with a stable system

I ran into the same issue with my Ryzen system. It turns out my motherboard has a "daisy chain" configuration, which means it's designed to pump more current into the primary 2 DIMM slots so that the user to achieve higher RAM overclocks. The downside is that the second two DIMM slots don't get as much current, so are unlikely to run at XMP frequencies.

 

I would look into whether your motherboard has the same config. Hopefully your second kit is still within the return period so that you can get your money back.

Try manually set timings?

Idk, I looked in the manual, it states that it's able to run all four dimms at 4266

That's because more RAM puts more stress on the memory controller. 

Try bumping up the system agent voltage a tiny bit.

so does mine, but it also depends on the type of RAM your using and its impact on the memory controller, as WereCat mentions. Check your motherboard's QVL, you should be able to find it on the website.

I'm not finding my exact memory model on the QVL...so does that mean I'm just up the creek without a paddle?

Unfortunately, that's likely. Are you still within the return period for your RAM? If you need 32gb, you're better off getting a 2x16 kit.

So new question for everyone on this thread, what's better, 32g at 2133 or 16g at 3200? Lol
