Thanks for the donation, and it is 100% to education not booze I've had a bottle of gin on my shelf propping up a computer rather than being drunk for the last year. Yes I am UK

Its pretty clean especially for 2 blades, they're much smaller than you think. Added Amazon referral links, was thinking against it as it clouds the purity of the guide but oh well. I also retired my main computer's gpus since these avalons. The pain from additional heat isn't worth the marginal increase in earnings.

The F12 fans are pretty crummy, cheap bearings, not great airflow at max and loud for the airflow they do put out. Thanks for the links.

Edit: Meant to say, I have that PSU powering 2 at the moment, but because both are on the same molex wire its overspec and I'm trading it in for a 750CXM.

dogie,
could you please confirm that this fan is PWM aware? On the site there is no PWM in tech specs, and it have only 3-pin header.

I've set up my blade after reading this nice instruction.

Thanks, dogie.

No problem

TroubleShooting

Three or four "x" in a row on "Chips": The corresponding power lane does not work or is not supplying enough voltage. Try measuring each power lane to find the dysfunctional lane and tuning it higher. If it doesn't work please ask us to send you a new power module.

More than two "x" scattering on "Chips": Some of the chips could not work on high clock in the current voltage. Try tuning the voltage of the whole power module a little higher. If it doesn't work please downclock to Low.

Hashrate turns to zero and all "x": Either the power module is broken or the whole blade has some problems. If you bought more than one blades, try using other functional ones' power module to test if it becomes OK. If so please ask us to send you a new power module. If not, please return the whole blade back and we will send you a new one. (we cover the shipping fee)

The blade misreports the hashrate to a very high number but hashes at a very low speed: Most probably it's the problem with the ethernet controller. Try hardware-rest it as shown in the online user guide. If it doesn't work please ask us to send you a new ethernet controller. It may also be caused by the misfunctionality of the hashing board. If you bought more than one blades, try using other functional ones' ethernet controller to test if it becomes OK. If not, please return the whole blade back and we will send you a new one. (we cover the shipping fee)

All or most chips are "O" but the efficiency is very low: This happened on two or three blades on our former products. Most probably it's some shortcuts on some of the chips' communication pins. It shouldn't occur in the second (current) batch, but if this happens we will do a free replacement.

(To be extended...)

Thanks Mr Cat, I've added to the OP. As the receiver of nearly $2M I think you should send me a free blade *puppy eyes* You have my details from batches 2 and 3.5

OP Updated

Pool settings

You changed pool settings and it got worse, its pretty obvious its your pool settings. Set up a stratum proxy on slush's and see how it goes. The blade itself is saying its fine and its not restarting.

Not being able to connect to the config utility suggests something with your network topology may be amiss.

Either that, or you've laid it flat on a table and the bottom is now overheating.
