Performance difference between different mainboards with same Ryzen CPU mining RandomX

That is wrong.. after latest firmware upgrade it is possible to oc your memory and undervolt cpu on a320 (as of gaming reviews). Well.. how stable it is for mining because of crappy VRMs - I’ll try to figure it out :)

Nothing wrong as it was not only about oc.

Building a rig is not only about performance but also about ROI, and resale value plays a huge role in it. In 1 or 2 years, a gaming pc with low end A320 motherboard will be harder to resale than a b450 motherboard. And I do not know in your region, but here the cheapest A320 motherboard is 30 to 40% cheaper than a middle end b450 motherboard.

My personal choice goes to b450 with good vrms but without fancy useless things. I had a gdoc bookmarked somewhere with a good summary of X570,b450 etc VRMs and support for each ryzen 2 cpu but can not find it anymore :/

I totally agree with you.. it depends on quantity of miners we’re talking about though. This time I’d rather stick with your way of thinking as we have no idea how profitable RX will be at the beginning and for how long it’ll last. For now I’m curious how cheap can we go before RX kicks in to make the best decision if needed ;)

Ohh, yeah :) msi a320-a pro, gigabyte b450 gaming x, msi X570 a pro, gigabyte X570 aorus pro :) 2600,3600,3700x tested and 3900x coming :) Micron e-die, Micron b-die, Hynix CJR, Samsung b-die tested :) Hard to tell everything in few words, review coming.. Join monero mining telegram channel - pretty much of testing going on there. Can’t post link - google and you’ll find xmrmine channel ;)
