I have something similar, a new board, one without capacitors, all of a sudden is not recognized anymore. I've moved it into nearly every slot, it is not recognized. No burn signs, at a visual inspection board seems like all the others. Any idea? Thanks. spiccioli

Ditto. I RMA'ed mine. Nothing obviously different about this board than any others.

Hi guys - since the latest round of H-cards was shipped at .865v, rigs pull significantly higher wattage. I'm seeing signs of connector burn & overloaded power supplies with some customers. Please be safe - if you are overclocking or running a full rig, a 1200 watt supply is probably a better choice.
Keep your rigs away from flammables - remember these are high-wattage devices!
I've been a little out of touch, sorry if this comes late - we don't have these problems at the data center. We use a 10g high strand count copper wire between 12v supply and the metal lugs on the M-board. The length of our power cables is only about 12 inches.
Best, Dave

Hey guys, did you ever get a board which will not hash no matter what settings you try? I have obtained one such board. All it throws are loads of errors. I have tested the usual suspects voltage, etc. It's a new PCIexpress style board, so I cannot bypass a chip.
I have tried disabling chips in software but the board will not hash. I tried it as a sole board connected to an Mboard.

Just to clarify after reading the fire hazard thread. I am using 2 separate pci express power connectors to power a full rig right now. Should I also power the 12V/GND power connectors on the other end of the M-board? The rigs have been running stable for the past month. V3M/V2.2H/Corsair 870 platinum, stock settings, about 650W at the wall

I assume it's ok to run power to both the pci express power connectors and the 12V/GND screw terminals?

Yes, that's what I do. I bought some splitters on ebay, cut them up, and added ring terminals, like what came with the v1 M-boards. I don't like hot connectors.

I mine PPC occasionally, i have automated the switching of coins based on profitability info from web. Pool i use is https://asktom.cf/index.php?topic=173272.0 which works fine. With bitfury it seems that what pool you are using means alot; with some pools, you need to remove the -rt from stratum proxy's command line. Also when selecting the pool, it's a good idea to select pools where you can manually set the desired difficulty. With pools that select difficulty automatically i've seen that sometimes the difficulty drops too low and then .putstat shows a lot of requests queued, and performance tanks...

I used ppc D7 pool and I thank you. I am going to try it later on.

I still get alot of errors with remove -rt and I used mining it with Aug. 25Gh/s starter kit.
edit: I used Minimum Difficulty 128 for 6 Hboards about 180Gh/s on D7 pool.

Just checked, i have -rt when mining to D7 pool. For me it works nicely, D7 shows the hash rate at 150-160 Gh/s (5 hboards, Bitfury management shows about 160-167).
I have stratum proxy set up to restart in 15 minute intervals, not sure if that has anything to do with this... no automatic restart for chainminer, even though i think it would be good to set that up too.

Hmm, seems it might be good idea to do some finetuning again, more errors than last check a week back.

work good for few seconds and one miso-errors then hashrate drop down and mass miso-errors. I might be h/w problem with my first hboard but everything work nicely for btc mining.

Can you tell me how you setup this automated switching? CryptoSwitcher will do that for you...had it running when I just had BFL miners, but it should work with these just as well. The only snag is that other sha256d coins usually won't make that much more than Bitcoin (right now, PPCoin will net you 18% more than Bitcoin, but that's before you exchange it).

Yeah, i found that software after i had written my own. It usually goes like this, if i get an idea about something that would be nice, someone has already thought about it and propably implemented it  . Well it wasn't complete waste of time, learned Python3 doing it and it works. If only i had more time to implement some nice guis for monitoring miner speeds, current pools and editing configs...
