ANTMINER C1 Discussion and Support Thread

Impressive. You are at 675v. What is your frequency?

When you run at 760v. How many watts you are pulling from the wall.

Most efficient test I have and am running them at currently, is 0675v, 800GH/s (200Freq on all 4), no 'x', 804-817GH/s averages, pulling 575-590watts (I have 3 of them running).

I tell you though they are not much quieter than the S3 I have running at 200Mhz/400GH/s.

C1's temps are all 33-35c.

I never ran 076v. Max I ran was 075 @ 250Mhz, 1008GH/s stock. I briefly test 275Mhz @ 1123GH/s but it was pulling 943Watts.

I love the idea of under clocking these. Please keep us informed.  Have you tried on multiple to see variance between miners?

Like I mentioned, I am running 3 of them. Underclocked, the C1's are ok, but otherwise, unless you have free or very cheap power, not worth it vs an S5 or better yet an SP20.

I'll be testing some S5's finally in a week or so as I got my hands on a few. We'll see how they compare to the C1. I think the C1 is strictly S3+ boards mated to a watercooled block between them. I'm actually going to look for an enclosed watercooling system that will eliminate the spaghetti of wiring and hoses this system requires. There has to be a way to make it nice and neat.

What's making the noise? If it is the fan on the miner, you can probably replace that with an almost silent fan. I never got that far in trying to replace that stock fan since they were quiet enough for me to have a phone call in the same room. And the fans on the radiator are just 800-1200 speed quiet fans I suspect. They should almost be silent to begin with.  I never owned an S3 rig, so I don't know what they sound like. The S3's are less quiet than the C1?

[thedreamer]

No the S3s are a bit louder than the c1. Not by much though. I will probably look into swapping fans later if they bother me. Not sure yet. Much quieter than my sp20s tough. Lolol

I don't think I ever noticed the sound on the C1 stock fan. You could probably get away with a 25mm completely silent fan on there, since the coolant is the primary way it cools I bet. I have a couple small servers running in my office and I think my ears are so use to that sound anything less I probably wouldn't even hear. Too bad there are 1,356,495 fans to choose from.

I have been running a c1 for about 2.5 months now.  I can't seem to get the "Rej%" rate any lower than 3.5%.  Its running with a Corsair T850M Power Supply and is set to normal speeds.

My nearest competitor that sort of reject rate on an s3 is .4% 

Thoughts in advance?

thanks.

Where do you see that?

All I see is the # 'Rejected' and on mine at least it's extremely low.

What pool are you using?   

I have 2 C1's running and both are far under a percent. And that is with pools switching from the DDOS stuff.

I use WestHash and BAN.

I use M's Miner Monitor v5.0 and there is a column that says "Rej%".

Only thing I can think of is if your using westhash as main, and on it's mining some coin that has a higher reject rate when mining through them.   

I know if you rent it through some places it can show for example blocks found, etc that BTC would never have (chances are) when mining certain coins.

But for a straight BTC that is would be very high might try antpool or ghash on straight btc. (Antpool is battling DDOS right now but was a very good pool with for me low rejects).

I think my previous post got removed or not posted correctly from my end. *Shrug*

Did Antminer disable the wireless part of the BeagleBoard Black in software, or hardware?

I wish they'd have kept the wireless function on there as it was a great option with the S3's IMO.

[MyRig]

Antminer with Beagle Bone Black as a part of the control unit does not have a built-in Wi-Fi support.

You may want to use some wi-fi bridge to make the miner think it is eithernet connected

Yeah That's what I'm doing, but would be much more convenient if they had it like the S3's did.

@Picolo and Beachguy!

Duly Noted.  Pass on to the engineers

How about fixing the inability to connect to a regular BTC node for mining....

About a week ago I upgraded firmware (yes it's old firmware I just never did it).  But after a week no problems with the firmware.

One is a little more babysitting with the X's but that was same before.  Other works all days if not weeks no problems.

What is the firmware date that you are using now?

I went from stock batch 1 firmware to the "SD-C1-20141217.tar" firmware.   So it's retaliative old but I just never got around to doing it.

But it's working for me just as good as stock did, so no regrets on updating.

Anything seem improved that would warrant violating if it ain't broke don't fix it?
