Hi, have question about CPU, my Ethereum-rig setup:
B250 Mining BTC+
Celeron G3930
7pcs 1660super
2pcs 1660ti
1pcs p104-100

I cant overclock memory clock above 720 before Windows crashes.
I've noticed that im lacking "full" overclock, 2-3 MH/S on each card, because I cant overclock the cards to its fullest. How do i know that, i have tested it on my i7 8700k and could reach memory clock at 1100. 

So do I need more cores or threads or both to run it stable?
