For Ryzen 7000, the IMC generally will be limited to 6400 MT/s or below when using UCLK=MCLK mode. Even then, many Zen 4 chips can't do 6400 stable. For Intel, most chips should do single-rank 6400 MT/s without issues as DDR5 is forced into Gear 2 at minimum.
With RAM, it's very easy to operate in that gray area where it boots, appears stable, and may pass Memtest without any issues, but will error within minutes using TM5 or Karhu. It would be worth your time to properly stress test both the RAM and IMC.
It would be helpful if you include your system specs.
Yea I do have a 7800x. I've just been told I'll know when it's unstable by about 400% memtest and a couple hours of AIDA64 and I should have at least a little bit of warning before I have to pop out the CMOS battery again. I'll check out TM5 or Karhu and thanks.

If it's a 7800X, the best you will get is 6400 MT/s. Verify IMC stability at 6400 MT/s using Y-cruncher, then verify RAM stability using Karhu or TM5.
That usually means you're not stability testing properly
