your FS messup that why you cant boot up.

f--k. figured as much. time to reload an image (i should back up my sd more often)

back up and running, minus a few miner tweaks and a chainminer update

something has happened.

the webUI is not accessible at 192.168.1.249
SSH times out trying to communicate

Ive tried with a second SD card to no avail, and the first 4 leds on the RPI are lit (ACT is not)

Do you have a micro USB phone charger, spare hdmi cable? YOu could use that to test your rPI with a HDTV / Monitor

Mine worked great for about a week. The 4th slot on my unit has stopped working entirely and getting more then half the slots working at the same time is extremely difficult and very short lived. It doesn't take long before it's running at 150gh or turned off completely. Seems like a M-Board issue to me, anyone have the same problem?

Update: Now only the first 3 slots of bank 3 seem to work correctly. Bank 4 works sometimes.

I mine PPC occasionally, i have automated the switching of coins based on profitability info from web. Pool i use is https://bitcointalksearch.org/topic/annppc-d7-pool-stratum-ppcoin-pool-15-pplns-173272 which works fine.

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...

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.

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.

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.

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 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.

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

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 think 2 cables might over load it but if me add 2 more cables to reduce heat up on pci-e cable.
