Epic SC200 report

I rececently got a epic sc200 miner and got it up and running. It seems to work but the accepted shares coming in are very slow compared to the goldshell hs-box I also have. The epic miner only gets an accepted share about once every 3-5 minutes, while the hs-box will get about 80-100 accepted shares in the same time. Datum recognizes that the epic miner is connected and shows it’s accepted shares, but never shows it’s hashrate.

Compatibility report:

Probably should upgrade to the 4.0.0 firmware.

Here’s a link to the last/latest firmware: Releases · epicblockchain/epic-miner · GitHub

I got the firmware upgraded to 4.0.0 and it is much better now, the hash rate is displaying too. It is still slower than the hs-box with accepted shares, even with the epic miners higher hash rate. This thing is energy inefficient per hash rate compared to the hs-box.

Thanks

Yes, not the most efficient. Did you see in the new firmware that you get MANY more (17) levels of efficiency (power use) on the SC200, from 1300w down to 500w? The Goldshell’s seem to be better optimized. Hey, at least I got a miner to test with and hope that demand encourages improved mining hardware developed for Blake2b in the future.

Yeah I did see all the different performance levels. I’ll probably run it on one of the ultra efficiency modes to keep the fan quieter since I have it inside a spare bedroom atm. Not a lot of options for buying miners right now.

Thanks

I’m considering on trying out the Epic SC200 but I’m curious if you mind sharing how much hashrate you get for running the Epic SC200 at 500W , 700W etc.

Would be helpful in knowing how much hashrate it gives since I can’t find it any where else.

Thank you.

I’m running it on 120v at 650 watts and it averages around 1.5 TH. Not the most efficient but it has been working without any issues.

Thank you!

How noticeable is the volume?

At that power level the fan runs at 30% and is not bad. I have it in a spare bedroom. I can hear it but it doesn’t bother me. Once you get above 750 watts or so the fan runs at 100% and is obnoxious.

I agree mostly w/ NumbSkull. ~1.5TH/s at 650-750W but fans need to be ~30% PWM, suitable for a garage in my opinion as it’s fairly loud.

Also wanted to note that if you set it lower (500W, 550W, 600W) and then change the fan speed < 30% it helps with noise (~1TH/s) but then sometimes the Fan Speed control logic will default back to 30% fan PWM. For me the spare bedroom and unpredictable Fan Setting does not work.

Cheers!
