DDR4 4400... that's pretty fast. Unfortunately, not all systems can handle that. You will have to manually tweak RAM settings to find the best it can do. I would dial-in the XMP settings; then maybe increase timings to CL20 instead of CL19. Or, lower the speed. 1.45V is pretty high for DDR3, probably the highest you would want to go. So, either increase timings or decrease speed.

Check the RAM is fully compatible with your motherboard by reading the QVL ( qualified vendors list) document on the manufacturer's website for your motherboard.

seems quite a few people are having problems with memory running at rated speeds and these mainboards.
do you have a 9900 K/KF too?

your board doesnt officially support 4400mhz looking at the spec sheet, and i didnt see any additions in the bios update descriptions, according to Aorus website, max supported speed is 4266 (OC), maybe you should try to manually set the speed at 4266 and C19
