@Picolo and Beachguy!

Duly Noted.  Pass on to the engineers

True.....the CGminer 3.1 is kind of long in the tooth.

Better firmware

What feature from S3+ you wanted to see in C1?

Picked up a S3+ off of ebay. I wish the C1 had a better firmware. The features on S3+ are way nicer.

My great low pressure air hose used on the miners developed a leak from my using screw hose clamps instead of the split ring.  Bubbles were circulating.  I repaired the leak  That was last night.  I refilled and let the pump circulate water with the miners off until no bubbles were showing after shaking the miners.  The miners started up okay and both ran over 1TH all day but I've been filling the tank most of the day as the level would sometimes drop.  The tank cap is loose so no pressure builds.  While watching TV the level dropped faster than I expected, this tonight, 20 hours after the first low water level.  I noticed when my hashrate dropped into the high 900's on both miners.  I filled the tank and bubbles stopped but C1#2 was only running at 7.5 amps while typically it runs higher.  I shut it down and restarted but now the third chain is all dashes.  I shut it down for 5 minutes and restarted.  No improvement.  Suggestions?

The other pump arrived in Atlanta today so I should have it tomorrow and will be able to split the systems.

PCIE to that board not supplying power....  And found the leak.  Now the level should stay okay.

Up and running, just fine.

-----------------

Pump arrived.  Put it in series, pushing into C1#2 -> radiator -> stock pump -> C1#1 -> condenser -> new pump.  I like its LED as one can see water level easier in dim light.   Very easy to cause the heavy, thick walled, air hose to leak at the ports when a hose clamp is used.  Went to Lowes and in the plumbing where the hose is sold, one can only find permanent clamps which require the purchase an expensive crimping tool.  Into the hardware section I found the heavy duty spring type clips.  With these on the ports don't leak but very difficult springs.  Asked about a special compression tool for these and was told he always used pliers.  So, the two C1's are still in a loop.  Wonder when they'll ship that radiator from China.  As it is the condenser is doing equally well as the stock radiator, in fact just a little bit better than the stock radiator by a degree on the hashing board to see the cool water in each.  Have noticed that when there's a leak and air gets in the circuit and the boards heat, the current goes way up.

ssh password admin on C1

A difficulty with my C1#2.  I changed the parameters including password and can log in on the gui.  When I ssh in, I register the key in putty then try to log in but my password isn't accepted.  Neither the new password nor password root are accepted in ssh.

Bothersome because I always like to command halt via ssh before killing power.  I found wakeup was less troublesome in earlier miners.

Signed in with admin as password, then changed root's passwd.

its CG miner 4.7.0

I used the modified firmware and it worked fine, however bitmain just put out a new firmware for the c1s just installed it have not tested the extranonce feature yet, hopefully they added the new cgminer to it right now I am locked into the current round at the pool im in, I wont know until i change pools after this round, anyone else add the newest official firmware and know if extranonce is working on it?

I flashed my C1's and they all work exactly as they did before except they have the newer cgminer running. I did not author the software, so I can't give you specifics.

I am confused as all hell what is going on?? lol Bitmain why release soemthing 3 months late?

Anyone try the new C1 firmware on the Bitmain site yet?

Interesting that the date on it is almost 3 months old...

I could not find it earlier. But for those who need in a hurry I used 2x of http://www.ebay.com/itm/381066536924?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT long ago.  Both working great ship from within US.

I did put the LED screw top in for fun.  No pressure issues or breakdowns.

So, opting not to use the quick disconnects for their reduced fluid flow I'm going with the standard barbs.  I have the nice low pressure air hose to cut up for water flow, 56 cents/foot, but picked up a $12, 50' PVC low pressure air hose from Walmart having threaded ends that match the C1.  Instead of barbs I'll use lengths of this to connect to the condenser and pump.  Pump isn't yet here but another day delay won't kill me given a barb is set in JB Weld on the condenser and won't be hardened until tomorrow.  I have fans from my Asicminer Blade days.  Five are mounted across with a diamond mesh metal shield to keep objects from coming into contact with the fans and breaking off a blade.  I have more fans and mesh if these don't drop the temperature sufficiently.  Scrubbed the condenser and applied air pressure while submerged and no leaks.  It looked as tho a tube was mashed and would require cut, crimp and seal but I lucked out.  When the pump arrives I'll circulate distilled water for a while, dump it, and replace then hook up the C1

Started using Eligius the other day with all miners pointed to a single address and that gave me a dependable read of how much btc my hashing earns daily.  Bummer.  An easy calculation given the Kill-A-Watt reading on my other C1 and cost per kw with its associated state and local tax (those raise it just a little over ½ cent per kw).  A C1 just breaks even almost to the penny.  I thought I was doing better than that.  Of course if btc goes up that's great.  I did feel new miners from the manufacturer might become harder to obtain and these will warm in the winter at a better cost than propane but that was a lesser reason for buying.  So, I decided to shut down my Saturn to be fired up if btc goes high enough or otherwise next winter.  I probably should shut down a lousy S3 that runs hot and has a falling hashrate problem.
------------
New pump still hasn't left Chicago apparently.  When it gets to Atlanta, that night it would leave for the PO so as to arrive the next morning so it isn't going to be here tomorrow.  Maybe I'll try daisy-chaining the C1's, pump->C1#1->radiator->C1#2->Condenser->back to  the one pump.

-------------------

Now wondering if the USPS is offering a get-the-customer-annoyed-international-shipping-rate-from-China.

I can say my two were not using the quick disconnects.   And 2 out of 2 did fail.   

Earlier reading of the forum there were reports of failed pumps.  I wonder how many of those failed pumps were pushing into the quick disconnect couplers shown on Dogie's Guide.  Those disconnects have ports half the diameter of the normal barbs. 

My order arrived today 2015-03-10 

Looks like n_howe1205 on Ebay can't be trusted to ship an $89.99 radiator w/fans in a timely fashion.
