I just figured it out and changed it with Sudo, no clue why sudo passwd root did not work for me before, I was totally confused as to why it did not but I must have just goofed it somehow.

try sudo su as root and no password

anyone have advice for NOT ruining the SD card everytime the unit power cycles?

I log in as root or become root and then do

# sync;halt

or

# sync;reboot

I don't do anything on the web interface before either of the two above.
Never had a problem.

What is the default root password anyhow, I have looked everywhere for it however have seen no mention of it.

yes, sudo reboot mess up my sd image too last week and sometime I did stop Bitfury admin then turn off psu work better than do reboot.

sudo shutdown -r now works well.

anyone have advice for NOT ruining the SD card everytime the unit power cycles? Using 'sudo reboot' after a chainminer update (because the SD got ruined and i had to re-write it using an image from early november, since noone seems to have uploaded an image with the chainminer update) ruined the SD for the second time today.

ps: of the 2000 newly stocked h-cards, only about 30 have sold. is there any plans to reduce the cost to something reasonable?

I think chainminer must write to the SD card and wear it out far faster than bfgminer. I've rebooted by pulling the AC probably 50 times now and have zero issues.

It did suddenly stop running stably after being good for a few weeks though. Update to latest bfgminer git and swapping the h-cards around seems to have fixed it.

I did have to disable the 50% frequency something reinitialization in bfgminer though, just commented the whole section out.

Edit: Heres the diff from git that I'm using. Doesn't run stable without mods for me.

In my experience the following has worked for ~100 reboots between 3 SD cards and PIs. I stop the miner first using the web interface. Then turn off the PSU. I have not used the shutdown -h now OR poweroff command for a while. Each time the PIs have rebooted up fine.

I am still shutting down the same way Goxed is but I am also still using shutdown -h. I was afraid of not shutting the RPI down. Guess I will get a new image ready myself, its about time for one.

Most people I have seen are using VGA RAM heatsinks. You just have to get a little creative about mounting it without botching the job. I have also seen at least one person use a surface mount MOSFET heatsink for mounting on the front.

I owe my soul to the Bitcoin code...

Just take a hacksaw to them, tape side up. Aluminum or copper is real soft so an easy cut.

Here is a closeup look at my card a v2.2 version H-card. I don't see anything in that spot other than the trimpot. Is it the trimpot, itself that needs the heatsink? Or that tiny thing labeled R01F?

The voltage regulator that needs to be heatsinked? It's the dark gray integrated circuit in between C01R and the Pulse inductor. I attached mine to the back rather than the front, though. It is tricky either way because you do not want to accidentally short the other components. On the front, the thermal conductivity is not as good. On the back, the heat sink barely contacts the area where the regulator is attached due to live traces and components.

So is it indeed the chip located above C01R that needs to stay cool ? For some-odd reason I thought it was C06 (SH 100 16V) that needed to stay cool. I guess it doesn't really matter as I have a hurricane blowing on those spots either way, but would be good to know...

Thanks for the insight ! Guess it's off to EBay with me to buy a bag-o-heatsinks.

Yeah the one above C01R is the one you want it gets pretty hot. Its a night and day difference for my cards, it runs with the heat sink in those locations and it will just plain shut down without them.

Great. I'll start looking for tiny heat sinks... The VGA RAM heatsinks I have now are way too large for that tiny chip.

If you look at the picture here https://bitcointalksearch.org/topic/m.3516385 Just underneath and slighty to the right of the the big square Pulse thing ( I dont know what its called or what it does) there is a smaller square you want one on top of that smaller square, and one on the other side of the smaller square covering the exposed metal.

Even at the discount rate these don't make financial sense. What a shame, I really wanted to top off two m-boards that I have.

klondike_bar, which h-cards version are you interested in? I wonder if we're allowed to mix and match the type as long as the total ends up being at or over 10.

V1.2 cards. I want 3-5 card for myself, and will happily reship within canada or to USA via xpresspost (2-3 day service) if anyone wants to go on the purchase with me.

Did this arrangement fall through? I haven't heard back from you.

I didnt get any answer from dave if boards would ship immediately or if they were still on the way from fabrication next week. In either case, I have decided that $750 per card (~0.9BTC) is excessive for the product considering even a 35Ghash speed. Obviously im not the only one, since MBP has sold all of 22 cards in the past few days.

When Dave drops the price to something reasonable, and/or prices his store in BTC, I would be more than happy to organise a groupbuy for a few ontario residents since there seems to be 3-4 people looking for a few cards each. Hopefully bitfury comes to senses and drops the price to 0.7BTC or less over the weekend, in which case i would go ahead with purchase

Yeah I completely understand and I agree that it's way overpriced. Ohwell, I guess we shall have to wait until Dave or the market comes back to reality.
