You should check your RAM settings, they currently run pretty low at JEDEC specs. You should check if they have an XMP profile for 3200 to 3800 MT/s.

It is running at 4133, for some reason MAC OS reports it as 2666. I suspect this is cosmetic. These sticks have 2 XMP Profiles, one for 4000 and one for 4133. Mobo detects it as 4133 and so does windows.

Being OCD, that urks me lol... Do you know of any ways in Mac OS to get it to Read the speed correctly? I tried both XMP Profiles and it still shows at 2666 in Mac. BUT, if you disable the XMP settings there is a noticeable decrease in performance so I know it is working at correct speed, well I believe it is, don't know for certain.

Running them at 4133 gets you worse performance than running at 3800 due to fclock/mclock not being 1:1 anymore.

What would you suggest? Manually setting timings to 3800 or just use the xmp profile for 4000?

Zen 3 should be running in 1:1 up to 1900MHz / 3800 MT/s. If you go over that the BIOS will set the fclock down. With a little luck you could get fclock to run manually at 2000 MHz, but might need some voltage tweaking.
Setting the timings manually to 3800 would be the easiest and more stable option.

So far trying setting timings manually is either dropping in performance on geekbench or not stable, I am still messing with it to get the fclock right

After trying the Fclk at 1800, 1900 and 2000 it actually is the best performance rating on geekbench when running at XMP 4133 and fclk at 2067 in bios.

Geekbench does not represent real world performance very well, a more consistent benchmark would be CB23 for example

OK, I will grab CB and do more testing... Appreciate the advice!

For those wondering where they can find a copy of CB23, you just need to search for Cinebench r23 (CB23).
