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?

you can check our website about miner products. Wink

I have 10 of them since something like 5 months. 2 hashing boards are dead from 2 different R4 so I mixed the 2 remaining working boards to make 1 complete R4.

6 controller boards also dead from electrical shutdown. I purchased some replacement S9 controller boards from Bitmain, reflashed them with R4 firmware and it works good.

Last week we had high winds and small tornados (really rare here), some tree broke and then we had an electrical shutdown, and 2 more controller boards died. I had only 1 replacement boards in hands so I connected 1 hashing board on an other R4, and the other hashing board also to an other R4. Original wires are long enough without modification. So I have 2 controller boards that control each 3x R4 hashing boards. Works really good. You have to keep the broken controller board plugued for the fan so your hashing boards doesnt fry.

R4 are not reliable at all and it doesnt worth it to send them to warranty. But... we already made profit on them even with a lot of dead boards so we don't really care if they die now.

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

I don't think there'll be any more batches of the R4. Too problematic even for bitmain. A shame, really. It was the only miner specifically made to be quiet, and I love my R4B2. R4B4, however, has never run at 100% for more than a week or two, and is heading back for a second time to get traded for different miner. Tongue
