Most of those motherboards are hard to find in the EU.
whats your opinion on ASROCK FM2A88X+ BTC seen some bad comments on newegg...
ASROCK FM2A88X+ pro 3 is another one.
These are amd boards that I plan to combine with a dual core cpu. I heard that the cpu must have AES if I want to mine monero?
Finally what about Asrock H81 Pro-G?
Hello Ol Timer. Things haven't changes since you left, the Z77, Z87, Z97, H81 based boards are still the best for mining.
Unfortunately, like you mentioned, they are hard to find. See if you can find an Asrock H81 Pro BTC V2 board, or a Biostar TB85 board.
Good alternatives are the MSI Gaming 5 Z97 which support 7 cards, but are slightly more expensive.
In any case, holler here https://bitcointalk.org/index.php?topic=1806061.420 many good folks from the EU who can help you get boards.
Now, the ASROCK FM2A88X+ BTC - I started mining last year and these were the only boards I could find. You cant use Athlon X4 cpu's with em coz its a socket FM2+, so get the cheapest Am4 APU like the A4020.
I have 8 of these boards, running 5 cards off a 750W Gold PSU each and never a hiccup in the last 10 months of continuous operation, so these are pretty good.
Happy mining.
