no idea honestly but other guys in this thread seem to be able to run it with 4 sticks at lower speeds

well that sucks… have you tried lowering RAM speed?

awesome, thanks 4 info!

I need both single-threaded performance but also as many cores as I can get. So 14900 is my best choice I think without breaking the bank with threadripper platform.

Exactly that. It’s not a problem if my simulations\renders are 4% slower or whatever, but if they can’t fit in the RAM, I have a major problem.
