One of the boards in my R4 is having some issues. It needs to be restarted every few hours in order to hash, otherwise my rate falls down to 4TH/s. One chip temp reading is way higher than the rest, at 97 while the others 3 readings are around 65-75. I'm guessing this probably has something to do with it. Any advice on how I should proceed? Bitmain wants me to send the entire unit back at my cost, which given the expense and time involved, has me thinking that I'd be better off keeping it as a 4TH miner and cutting my losses considering the unit never functioned properly. Especially since they'd probably deny my claim because the first thing I did was remove the boards to see if there was a loose heatsink. Any advice? Should I send the malfunctioning board in for repair? Should I try buying a new controller to see if that is the issue?
Did you try asking bitmainwarranty?
Most likely it is best to just mine with 1 board if you have to ship entire unit to China.
I would think it is 200 to ship it.
I just got an idea. How many people are in your spot.
If you and a guy just like you put 2 good boards in one machine and 2 dead boards in the other machine.
then send the dead one to china it would allow for constant hashing with 1 full machine
and only 1 shipment to china. so shipping to china is ½.
it would actually save bitmain as they would only need send 1 machine back to the usa. I think they pay for return shipping.
So I ask bitmain would you allow this. It helps everyone involved with the exception of fedex/dhl/ups
If they would allow that, then they'd allow just the boards to be shipped back. They don't do that because they'd rather play warranty games and screw people like myself that check for loose heatsinks as we've always been asked to do in the past.
Bitmain should just be honest. There is no warranty. In the event they ship you a broken unit, you have to pay the costs to get it repaired, you are out uncompensated time for not having the machine, and by the time you receive the repaired unit if it works (so far they're 50% with returning me still broken parts) they're already selling them for less brand new. Rather than a pretend warranty, they should just ship their miners with an extra board and controller as that would probably be cheaper for those involved than having to ship their units around the world on the customer's dime.
I really hope BitFury comes to the home market in 2017...
