I don't know MSI either but RandomX isn't dependant on DRAM speed so it's a waste of time to tweak it.
Don't spread lies. It is dependant on RAM speed and latency, we're talking about the difference between 12 kh/s and 15 kh/s on 3900X.
Randomx is dependant on latency which is why cache performance is more important than DRAM speed. There's no way
increasing DRAM performance, even by 25%, will increase the hashrate by the same amount. Huge pages, on the other
hand, can have that much of an effect by reducing effective memory latency with fewer TLB lookups.
I stand by my advice. There's nothing wrong with faster DRAM, it's just low on the priority list in this case.
