Hello
I have a Obelisk Desktop 875-1040st, Product# 6FH15AV
I was wondering what is the fastest RAM speed I can upgrade too on this motherboard. I currently have 2x8GB DDR4 @ 2666
CPU = i9-9900K @ 3.6GHz
Documentation seems to be seriously lacking for my computer and other HP parts.
Thank you

Hi:
When you can't find info on your PC, the best thing to do is to go to the Intel website and check the processor specs, which normally show the fastest memory the processor will run.
In the case of the i9-9900K, the processor will run the memory at a max of 2666 MHz.
This was the only info I could find on that model from HP...
