Title: Low hashrate Avalon 851 Post by: maxomid on March 11, 2019, 07:56:17 PM Hello
I Have trouble with this Asic , its Hashrate is very low.. PSU 1800W Please see the screenshot https://i.imgur.com/ssypQxh.jpg https://i.imgur.com/fE4zwAG.jpg https://i.imgur.com/Q7Un47H.jpg Title: Re: Low hashrate Avalon 851 Post by: HagssFIN on March 11, 2019, 08:00:47 PM You might want to post the Cgminer API log for starters!!
Title: Re: Low hashrate Avalon 851 Post by: NotFuzzyWarm on March 11, 2019, 08:16:37 PM And also post in the Avalon Support thread https://bitcointalk.org/index.php?topic=3224256.0 along with reading that thread - at least the 1st post - as you may find your answer already there.
Oh, and when posting the API log please be sure to use the CODE tag (looks like # ) so the log does not become a wall of text.... Title: Re: Low hashrate Avalon 851 Post by: philipma1957 on March 11, 2019, 08:36:04 PM I looked at your screen shots they are for 5 minutes
and you overclocked to +1 so try showing a 1 hour screenshot not a 5 minute screen shot and try it with no over clock 5 minutes is pretty much worthless for telling true hash rate. and the 851 is power mad hungry on over clock so the 1800 watt psu could be too weak do no over clock please.

My device is new. But its Hashrate is very low :-[ Average Hashrate 9.5TH/S Watch new IMG what should I do? https://serving.photos.photobox.com/30549355ae54f0696dba2719e8123b61ea22a876bad6fdd942989e2a96f3df9a61f5a3a4.jpg https://serving.photos.photobox.com/7531579818d50c79a9b7553210be6b692310a135286489d5302b59047225e0d273cb77c9.jpg https://serving.photos.photobox.com/06933474f7c2a0151e35cfdb9d1456ea2c77e8166b9d8ad82d64727b277779f95b69fb49.jpg Title: Re: Low hashrate Avalon 851 Post by: NotFuzzyWarm on March 12, 2019, 03:54:37 PM The Avalons report what your PSU is feeding them. Check Status > CGMiner API log. Near the top you will see:
Code: [Firmware Version] => Avalon Firmware - 20180305 The line Vi tells you what the PSU is feeding to each of the PMU's (Power Management Units) and PG is a generic Power quality value. In my above example the PSU is feeding 12.03, 12.03, 12.12 and 12.12v to each of the PMU's and PG is the typical value of 15 (very good). If PG goes below 13 or so you will have problems with boards dropping out. Using the Code tag (looks like # ) post your API log here.

Title: Re: Low hashrate Avalon 851 Post by: philipma1957 on March 12, 2019, 08:26:31 PM that psu is no good it does not have enough power it is 1600 watts not 1800 watts.
set the miner to 0 not +1 show me a 2 hour hash rate Tell us your native language. Title: Re: Low hashrate Avalon 851 Post by: maxomid on March 13, 2019, 11:08:42 AM Hello
CGMiner API log See Screenshot So the problem is the PSU? Bitmain Antminer APW7 1800W Power Supply For Avalon 851 Is it right? https://serving.photos.photobox.com/25262526a3919324b252562bad52780b59eebe078dcb057bcb31cef268084449a0d74959.jpg that psu is no good it does not have enough power it is 1600 watts not 1800 watts. set the miner to 0 not +1 show me a 2 hour hash rate Tell us your native language. :( My Psu it is 1600w? 0 or +1 Average Hashrate 24h 9.5TH/S. Title: Re: Low hashrate Avalon 851 Post by: HagssFIN on March 13, 2019, 07:27:25 PM Dude,
You have the new low power firmware installed. That's why your hash rate is lower than stock A851. Please read this carefully to fully understand what I mean: https://canaan.io/avalonminer-8-series-high-efficiency-firmware-released/ (https://canaan.io/avalonminer-8-series-high-efficiency-firmware-released/) Title: Re: Low hashrate Avalon 851 Post by: maxomid on March 13, 2019, 09:31:36 PM Dude, You have the new low power firmware installed.
