On the November 26 firmware, when setting 275MHz, it comes up as 2,275  Huh Roll Eyes yet another rushed firmware by bitmain...how many other typos are in the code  Lips sealed ...can we get a fix for that (or location of the frequency table)?

tubes for the radiators soften if the miner has temperature over 40C

Thats.... thats just physics...

Physics yeah, for the "quality" of the tubes.

No, that's just how all materials behave when heated. All watercooling tubing is exactly the same material - acrylic. It is ALWAYS going to 'soften' when heated. I'll give you $50 if you can send me acrylic watercooling tubing that doesn't get softer when heated.

Lastly, is it possible to use a pair of 650W PSU instead of one big one?

Got lots of smaller 650W PSU's made by Corsair and SeaSonic, a high quality 1000W is a C$200 bill I don't really want right now.

Yep, it's possible. Due to lack of power I connect in parallel 2 PSU's. One is XFX 750W and another one is Antec 750W. You can buy on EBay appropriate connector.
Another solution is to do connection by yourself like I did (because still waiting for this fu...ing connector to arrive from Korea).
You should connect green wire from 24pin connector to both PSU's and one of black wire in same manner. I put switch between those  2 wires to start or shut-down PSU's. Than you can use PCIe rails on your C1 from both PSU's. It's work great since day 1 for me.
Sorry for my english, but I hope you got idea.
Best regards.

I'm trying to stop the cgminer process on my C1. I'm doing that with
Code:
/etc/init.d/cgminer.sh stop
. This works but cgminer starts automatically by itself after a short while, so there is obviously some other process monitoring and starting it again. Anybody know what process doing that?

Thought I would report a successful custom water cooling setup for two c1's. I used some parts I had lying around from some of my old watercooled PC's.

1 D5 Pump with EK Pump Top
1 560mm Rad GTX560
8 140mm Fans in push-pull

Both C1's in series (refer photo and some screen grabs of the temps which are remarkably even across the two units)

Currently both are overclocked to 262.5 with the default voltage.

Can you or anyone tell me where the guide is for overclocking the C1? The older setting I know from the s1-3 are not working and I searched everything I could think of but cant find it.

the wires are so thin

I had to cut the wire on the harness because I needed 4 pins molex instead of pci-e. There is just a flimsy copper wire the size of an hair inside of it. But it's working. My kit was in perfect condition. I'm loving this near silent miner.

Your pump leaked.  Did you leave the fill cap open until the water heated up? Also do not overfill the pump because air will compress more easily than water.

Those having harness problems I love this little adapter molex to 3 pin adapter - http://www.amazon.com/Phobya-4-Pin-3-Pin-Splitter-Connection/dp/B007S3T4O0/ref=sr_1_3?ie=UTF8&qid=1418516992&sr=8-3&keywords=molex+to+3+pin

Have had two working great on that adapter.

C1 arrived in a record time. Miner is ok, but the cooling kit is the worst thing i have ever seen. The water pump leaked on the first power up and died after 1 minute work, wiring for the fans is bad soldered and the wires are so thin, tubes for the radiators soften if the miner has temperature over 40C. They should take care about this. Syscool should raise the price for 5-10 usd and sell quality not quantity ! ! ! Next purchase will be only miner. I dont need crap

Think all the items are directly available from Swiftech in stock.  I actually purchased an additional radiator from eBay which is working fine.  http://www.ebay.com/itm/240mm-280mm-Radiator-Aluminum-Barb-3-8-OD-Black-G1-4-Thread-For-PC-Water-Cooling-/191208931188?pt=US_Water_Cooling&hash=item2c84f0bf74   I was initially looking at seeing if I could set up 2 C1's on a single EVGA 1600w P2 power supply (I have in another rig, theoretically is should handle both at the 0725 volt. setting but not at the 0760 setting, but it's pushing it) in a Corsair Carbide Air 540 case (with this fan controller http://www.amazon.com/AeroCool-Touch-E-Temperature-Controller-CoolTouch-E/dp/B00GMYATYK/ref=sr_1_cc_7?s=aps&ie=UTF8&qid=1418492460&sr=1-7-catcorr&keywords=AeroCool+fan+controller ) with that Swiftech pump (might consider trying 2 of the ones that come with the C1 first) and this additional reservoir http://www.amazon.com/gp/product/B003LMNL8C/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 (3 of these fans on the front side pushing in of the 360 radiator http://www.prolimatech.com/en/products/detail.asp?id=2722&page=1 and 2 of these on the back side pushing out of the 280 radiator http://www.newegg.com/Product/Product.aspx?Item=N82E16835233093 and one of  these on the backside of the casehttp://www.prolimatech.com/en/products/detail.asp?id=1906&page=1 and the C1 fan upgraded to http://www.amazon.com/gp/product/B00A460TK6/ref=gno_cart_title_0?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
It would be a pretty compact set up, I'm still considering completing if the S5's don't come out soon.

I was in the same boat and was looking at other pumps incase this one leaked when it arrived.  It's been working fine so far, but this is the one I had my eye on incase:  http://www.frozencpu.com/products/14568/ex-pmp-171/Swiftech_MCP35X_12v_PWM_Controlled_Water_Pump_-_White.html?tl=g30c107s153 (1,000 L/H) with the optional 100 reservoir tank and heatsink, but it's a pricey alternate.

Yikes, 1,000L/h that nuts, overkill for one miner.

The one reviewer claims it gets very hot and heat sinks are sold for those pumps...

One step forward and one step left IMHO Undecided

Can someone recommend a good/better/reliable water pump for the C1??

I keep reading horror stories about those things going all the time, might be a better idea to get a better built pump.

I think I found one on Frozen CPU...

http://www.frozencpu.com/products/22869/ex-pmp-281/Alphacool_AGB-Eheim_600_Station_II_-_12V_15127.html?tl=g30c107s153

It looks solid and I believe Alphacool is one of the good ones.

You see, I'm good with both computers and cars but cooling systems, I always avoided... gives me headaches.

Would a 600L/h pump work on a system designed for 450L/h?

I like the idea of more flow but don't know if the system itself would take it... again, lack of knowledge on the matter.

Or, even better yet, is there a ready made upgraded cooling kit for the C1?

Lastly, is it possible to use a pair of 650W PSU instead of one big one?

Got lots of smaller 650W PSU's made by Corsair and SeaSonic, a high quality 1000W is a C$200 bill I don't really want right now.

Here's some info. I'll pass on.

The first firmware has the voltage set to 0725, this runs my C1 at about 760 watts DC (after the power supply, multiply by 1.09 to get the approx. power draw at the wall with my Gold power supply on 120v AC).  My C1 runs about at or above the 1,008 Gh/s minimum at this original default voltage, temp. reading is about 50.
The second firmware ups the voltage to 0760, this runs my CA at about 830+ watts DC (after the power supply, multiply by 1.09 to get the approx. power draw at the wall with my Gold power supply on 120v AC).  I believe this was done to guarantee a 1,005 Gh/s minimum.  So if your C1 is running OK with the first firmware, you might want to try the original voltage to see if your C1 runs OK at that voltage, you'll save on heat (over 5 degrees less) and power (over 70 watts).

BitMain got my C1 working this morning.  Seem with the router you need to select a IP address OUTSIDE the range (under .63 I think) to work in Static IP (with DNS and gateway set to 192.168.1.254).  Trying to find the Pool Balance setting though, is it only a default of FAIL with the C1 or can you select BALANCED or UNBALANCED somewhere in the settings?

Is it possible to overclock the C1?

If the frequency changes, does the voltage also need to be changed?

Yes and yes. You will officially lose your warranty if you overclock, but you may be able to get a reasonable overclock. Efficiency will go out the window and you'll need sizeable PSU headroom though.

Received my C1 yesterday with watercooling kit.  Set it up today.  No problems initially, pump not leaking (could all these leaking pumps be due to overfilling?  The instructional video seems to show the pump being filled to the very top, but when the liquid heats up it expands, if it's completely filled where is it going to expand to?  Might be something to consider to fill it less full, so the air in it can compress when it heats up.  I've completely filled mine so I'm thinking about removing some fluid).  Did have 2 of the radiator fans connected to one header as others have pointed out.  My fan/pump power cables are connected to a PCI 6-pin power adapter that instructions state to connect to one of the open ones on the C1 which is new to me.
Anyway after doing some initial setting it was hashing, but went to log in to change something and was unable to.  Get the Antminer C1 screen but no request to login and all blank.  Tried the 10 second on the rest button and power recycle but same results.  Looks like the SD card image might have become corrupted as happened with many others.

EDIT:
I was able to get it working with HDD Raw Copy Tool reflashed to the SD card with the image BitMain linked me to in an e-mail, but it was the old firmware so when I upgraded the firmware I got the same blank AntMiner screen.  So I'm reflashing the SD card to get it working and hoping for a link to the image file with the new firmware included.


I fill them right up to the very top and then screw on the brass screw cap just enough so if any pressure builds it can release from there. And no evaporation issues. This has worked best for me.

The ideal is you leave it capless until you get up to steady state running, then close the cap.
