I want to purchase a few R4's but Bitmain is sold out and they cost 3x as much from resellers - when will the next batch come out for order on Bitmain's site with the proper price tag? When did the last batch sell out?
I have two of them. they are quiet but have reliability issues.
this miner has a replaced board freq 468 is the highest it can do without issues on the replaced board
see it drops asics at freq 483
