Able to POST at 4,000Mhz, but only 3,600 shows in CPU-Z?

I have a Gigabyte Z390 Gaming mobo right now and i've tried both a 3733mhz Patriot kit and my current 4000mhz RGB team kit. The patriot won't post past 3400 and the team kit won't show more than 3600mhz in windows. I could overclock the team ram more than that and go into windows at first, but it wouldn't show the right speed.
So my question is, should I keep working at this or disable XMP? I did some research and it doesn't seem like people are getting 4000mhz on ram off this mobo, if someone has a suggestion for a high-end mobo that doesn't have ram issues, i'm all ears!

Is your RAM on the QVL? That's your problem, not the motherboard. There are several 3866/4000 kits of RAM on the QVL for your motherboard.

You'd be hard pressed to find a Z390 that couldn't do 4000. My Taichi will do 4160 (100.7 BCLK) all day just fine and will bench at 4200 but that's about it and that's a bit on the low end for Z390. Buildzoid got a Gigabyte Aorus Master to run 32GB @ 4533 and the MSI MPG Z390I Gaming Edge has the HWBOT record (DDR4-5737) for DDR4.

Pick your poison

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)
AMD X4 960T Zosma @ X6 4870mhz (+62.3%)
Intel i7 6700 Skylake @ X4 4709mhz (+38.5%)

I guess I really screwed up there, both ram sticks are not on the QVL http://download.gigabyte.us/FileList...x_20190415.pdf I had no idea it had to be that specific.
Not even sure what sticks on that list would do 4,000 but I feel like I made a mistake going for the giga gaming X. Really don't want to buy more ram again so guess i'll have to endure 3,600 speed

EDIT: On Team Groups site for my ram it says "Z390 GAMING X NIGHT HAWK RGB 3000/3200/3600/4000" So obviously 4,000mhz should be a reality. I'll keep trying XMP tweaks.

I couldn't boot above ~2800 on the earlier BIOSes for my Taichi, you could try updating if you're not already on the latest.

If you're just setting XMP and it's failing it could be your issue too, try setting speed/timings manually, don't leave any on auto.

Your RAM should have a QVL too. If it's on one of them you should be fine.

I forgot my bios got rolled back, so I updated it to F7 and was able to actually get it to POST @4,000mhz.
The issue is, just like with 3,800mhz before is that CPU-Z still shows DRM Frequency @ 1800mhz.

How is it possible to be running at 4,000 in XMP and still only be getting 3,600 effective? (Assuming cpu-z is reading correctly)
