Hi guys.

I have been trying for months to get this to work, so I thought I would reach out.

I the flagship ASROCK Aqua Z490 motherboard
Intel I9 10K 10900K
Corsair 32GB Kit (2x16GB) DDR4 Dominator Platinum RGB C19 4000Mhz - White (CML32GX4M2K4000C19W) x2 64GB Total

The problem is with the memory. I cannot get it run beyond 3500 speed. XMP profiles do not work at all, and if I manually increase the clock speed, I cannot push it past 3500. The memory shows as compatible on the website. Can you lend a hand?
Thanks!
