https://bitcointalk.org/index.php?topic=647251.0you can mine xmr (monero) with that 64 core , im not sure what has rate that 64 core can produce. and im not sure Claymore's CPU Miner can handle all the 64 core ..
with Claymore's CryptoNote Windows CPU Miner v3.5 you can mine :
XMR/QCN/BCN/FCN/Aeon/Duck/Dash/OEC/MCN/ORION
You need to create a wallet first for your mined xmr's
for example :
https://freewallet.org/im using 8 core on Xeon-E5-2666v3 it give me around 350H/s , that is making around 17$ a month right now with current difficulty and xmr/usd exchange rate .
if im using 10 core on the same cpu for xmr mining i can get + 500H/s , that is making around 24.5$ a month right now with current difficulty and xmr/usd exchange rate .
