Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 03, 2018, 02:50:28 PM i hope canaan made something about the rising power consumption at growing ambient temp... it is supposed to help this. I have all the youtube videos and tests on the 841's and under highest temps and settings it can be more then 100 extra watts as you go past 80f up to 97f 97f was max temp test I did. here are the 841 numbers https://bitcointalk.org/index.php?topic=3375954.0 Title: Re: Avalon 851 on its way. Post by: NotFuzzyWarm on August 03, 2018, 02:51:15 PM i hope canaan made something about the rising power consumption at growing ambient temp... That is not just a Canaan issue. The s9's also increase power consumption as temps rise. The Bitmain & Sorcerer PSU's and probably most others drop efficiency as well. Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 03, 2018, 02:56:39 PM That is not just a Canaan issue. The s9's also increase power consumption as temps rise. So do the Bitmain & Sorcerer PSU's and probably most others as well. yes the apw3 + does not fare well past 85f But even corsair 1500 titanium atx has heat creep issues. it did the best of the 6 psu's I tested. all psu's I used had heat creep they all want to be under 80f and they all liked 65f or close to it best. One thing the 841's can run in a 97f room for days on end they did this during our heat wave. both the s9's and the T1's dropped boards not the 841's Title: Re: Avalon 851 on its way.

The Bitmain & Sorcerer PSU's and probably most others drop efficiency as well. 100% truth! During these 100-112 days we had here in Texas my 2 S9s and 1 S9i used up to 4700 watts total when room temp was 108-109 F. Usage would drop down to around 43-4500 in the evenings as it cooled down. All 3 PSUs were APW3+++. Also meant to say my Whatsminer M3's would use up to 2400 watts each in high temps! Title: Re: Avalon 851 on its way. Post by: KaydenC on August 03, 2018, 03:45:41 PM Is Avalon 851 the 7nm miner or a faster 841?
I have not seen official announcements of the 851, and on twitter the 7nm miner leak was called Avalon A9. https://twitter.com/redtheminer/status/1024307705006022657 Title: Re: Avalon 851 on its way. Post by: NotFuzzyWarm on August 03, 2018, 03:50:13 PM Is Avalon 851 the 7nm miner or a faster 841? Within any Avalon family all use the same chip so the 851 has same 16nm chips as the 821/841's do.I have not seen official announcements of the 851, and on twitter the 7nm miner leak was called Avalon A9. https://twitter.com/redtheminer/status/1024307705006022657 Title: Re: Avalon 851 on its way. Post by: mgoz on August 03, 2018, 11:26:02 PM What are the specs? I'll probably hold out for the 7nm unless the 851 is $1k or less. Seems like a repeat of 821 and first batch buyers will just get burned again when they release more efficient model shortly after that will probably be cheaper. 821 preorder was $2899 and shipped about 2 weeks before 841, which was $1999. I'd imagine not many other than first batch buyers bought the 821. They do have an opportunity to sell a lot of these if specs are equal or better than T2 Turbo and pricing is better than Inno; $1350 currently and shipping in 2 weeks.

Those 821's are good but not that good. 7nm needs to be priced right. Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 04, 2018, 04:38:24 AM The 851 seems to be 14.5 th at 1350 watts. edit more like 1550 watts
All lower powered gear below It looks like innosilicon drops its gear first at 70-75 watts a th. In 2 weeks. Then pangolin whatsminer m10 due in sept does 65-70 watts a th.

APW7 can withstand higher temperature --> efficiency with rising temp: its all about the miner No it is a combination of multiple factors. psu miner load on psu ie 1500 watts on a 1600 watt psu is worse then 1500 watts on a 2400 psu. I also set the psu's I tested next to an ac vent so that the psu was ac cooled in every case with every miner efficiency was better. My tests with: s9 avalon 841 Halong T1 with 2400 watt delta plat 2500 watt hp Gld 1500 watt corsair tit avalon scorcer bitmain apw3 + Halong dell plat all show ac cooling the psu make it more efficient all show heat make the power draw higher. and the s9 is less affected by heat as to power draw the halong T1 has good selections of speed to avoid power draw but that both of the above are more inclined to drop boards when ambient air temps go over 95f the avalon 841's never ever drop boards even when NJ had a heat wave in early July and the ambient air was June 27 73f > > June 28 88f > > June 29 90f > > June 30 95f > > July 1 97f > > July 2 95f > > July 3 90f > > July 4 86f > > July 5 88f > > July 6 82f Data above is from https://www.timeanddate.com/weather/usa/freehold/historic?month=6&year=2018 Our setup is in this converted barn I developed a heat shielding method and the two 1600cfm fans keep the air temps 3 or 4 f lower So that loft space was at 92 when it was 97 both the halongs and the s9's drop boards at those temps https://i.imgur.com/5em72rF.jpg (https://i.imgur.com/5em72rF.jpg) Title: Re: Avalon 851 on its way. Post by: TheYankeesWin! on August 04, 2018, 12:35:45 PM So which of the three do you prefer?
Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 04, 2018, 12:36:25 PM @ yankees
I don't know how to answer your question But the avalon company and I exchange emails pms and have a relationship. I also have a relationship with Halong and Yoshi with the T1's. Bitmain and I do not have an email or pm relationship. Innosilicon and I do not have an email or pm relationship. So I am naturally going to favor companies that will work with me and treat me like a valued customer. If you are a newcomer and don't know any of the companies a lot depends on your pocket's depth. also the warranty service has meaning if you have a small setup. So avalon's 2 year warranty is good if you have under 20 pieces. If you want to open a 200 unit farm bitmain's gear is cheap and you can buy 220 s9's for under 120,000 so the 20 are your spares But a lot of this is a moot point since new gear will arrive from more then 3 companies. All by Dec 2018 Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 05, 2018, 03:52:22 AM It just got in to nyc airport .
Due Monday . New gear is always fun. Title: Re: Avalon 851 on its way. Post by: HagssFIN on August 05, 2018, 05:30:34 PM Was that the Chinese market only model they released? Yes. They sold it in Chinese and South Korean market only. I have a picture of it in my thread about my trip in Beijing and visiting Canaan. Title: Re: Avalon 851 on its way. Post by: minefarmbuy on August 05, 2018, 08:48:32 PM Yea, I was hoping to see a fully assembled one get the general idea though. Can't wait for pictures from philip.
We've requested a 851 to blog about, still though little response all around from manufacturers. Since we're not doing technical reviews it will be more of a marketing role and fall on my plate. I do appreciate Lily being responsive she's been great to communicate with. Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 06, 2018, 05:51:29 PM It arrived it looks exactly like the 841
specs on label are different 14500 gh 1450 watts. I am still running around hard but right now I will bring 1 of the 2 to the solar array and simply daisy chain it to the 3 841's Title: Re: Avalon 851 on its way. Post by: minefarmbuy on August 06, 2018, 06:58:05 PM So no attached psu?
Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 06, 2018, 09:16:44 PM So no attached psu? No just the miner. So I ordered a rasp pi as it does not seem to work with the rasp pi for the 841. I have a dongle/auc3 and wires on hand. I will post on this in a bit. Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 07, 2018, 12:17:40 PM Waiting for a new rasp pi to arrive.
and looking for a link to load it with the software. found link https://github.com/Canaan-Creative/avalon8-docs/wiki/AvalonMiner-851-firmware-downloads Title: Re: Avalon 851 on its way. Post by: Steamtyme on August 07, 2018, 12:18:19 PM Looking forward to the test runs.
Not sure how far out we are from an A9, these are just an optimized version of the 841, and from what you have on the label it looks like just that. I wonder if the voltage settings will work the same as they did for the 841 for this model. I don't think Canaan will be going the integrated PSU route again, sounds like the 761's were a disaster to deal with. Personally I'd rather source my own PSU anyways.

I don't mind not having the built in psu which would have been a 861 I found info on it. The 851 simply appears to hash at 14.5 th and 1450 watts It did not work chained to the 841 chain but the new rasp pi arrives today should have this running soon Title: Re: Avalon 851 on its way. Post by: frodocooper on August 07, 2018, 09:27:31 PM It did not work chained to the 841 chain That's most likely because the Controller in your existing chain of 841s is running pre-851 software. The 841s and the 851s should work on a Controller that is running post-851 software, as the Controller software for the 851 seems to have retained the code needed to support the 841s.

Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 10, 2018, 12:27:33 AM the plain model 3b came and boots
the model 3b+ does not so either my rasp pi 3b+ is a dud or the 6/28 firmware works on model 3 only. next step is firing up unit. she is working yeah baby. Settings are a slight voltage down clock and this is a myrig psu https://i.imgur.com/q8nTRE1.png (https://i.imgur.com/q8nTRE1.png) Title: Re: Avalon 851 on its way. Post by: HagssFIN on August 10, 2018, 07:00:28 AM Ok, thanks for testing it out!
So it's better to buy the original Pi 3 if you want to be absolutely sure that it works. Title: Re: Avalon 851 on its way. Post by: NotFuzzyWarm on August 10, 2018, 02:39:09 PM My guess is that his RasPi is DOA. 2 out of 3 that I've gotten last month (both branded Avalon ones from Blokforge, separate orders) were dead. In 1 the CPU instantly got literally smokin' hot, the 2nd no signs of life at all. BF of course promptly replaced both.

Post by: minefarmbuy on August 10, 2018, 03:36:07 PM 1550 for 14500 hash 1550 seems high or is just my novice assumption? Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 10, 2018, 04:00:49 PM 1550 seems high or is just my novice assumption? actually I am getting worse numbers then that while the 14,500 hash is nice I got numbers over 1600 watts in a 83f room I moved it to a hotter room for more testing I will need to play with settings it will take more then a day to get a feel for what it really does. Title: Re: Avalon 851 on its way. Post by: ogombii on August 10, 2018, 06:09:15 PM all indications show that the 1600w sorcerer psu isnt enough for the Avalon 851s, best to buy 1800w psu from now on! Even Bitmain has stopped selling 1600w psu.
Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 11, 2018, 01:09:40 AM I moved it to a warmer space.
I set it up with a hp 2450 gold psu. It hashes well at over 14200 It pulls more then 1850 watts I have -2 power setting. The room is hot 90 f if you look here it is obvious my settings are not underclocking the gear.

Title: Re: Avalon 851 on its way. Post by: Steamtyme on August 11, 2018, 03:07:33 AM Looks like it's a power over efficiency model. I wonder if it's something they can adjust through firmware?
I see the first test was voltage-level- -1 And the second was voltage-level-offset -2 if you look here it is obvious my settings are not underclocking the gear. With the 841 I'm running, when it's above 30C temperatures using the offset command is borderline shutdown? Did you try just the level -2 option? Were you seeing any change with any of the voltage adjustments from baseline? It would be a shame to lose that control, as it was a life saver with the 841. Title: Re: Avalon 851 on its way.

The 851 seems to spend way more power for an extra 1 to 1.5 th the 841 sets lower to 12.9 th and burns 1310 watts in a hot room when down clocked this unit won't get under 1400 watts or even 1500 watts and it gives me 14.2 to 14.9 th I don't mind the higher hash rates I do mind the much higher power use-age my meters tend to overheat and die at 1850 watts plus .

I placed the psu to get cooling from an ac vent. watts 950 https://i.imgur.com/ok9TAfx.jpg temp is at 6 foot height about 9 feet away from gear https://i.imgur.com/58qNry5.jpg gear note corsair ax1500i psu https://i.imgur.com/hgKQOBr.jpg note ac vent which does push some cool air towards psu https://i.imgur.com/JRGajIh.jpg 8500 using 950 watts is about 0.111 watts a gh the point of tests like this is to show work arounds it means you could use any 1200 watt atx psu in a pinch even with 120 volt power. it also allows for use in a hot space during the summer. this gear should not have overheating issues at this setting if you area to mine is fan cooled and runs warm in the summer this setting should work for you. here are the five under clocks that work for me --avalon8-voltage-level -1 --avalon8-voltage-level -2 --avalon8-voltage-level -3 --avalon8-voltage-level -4 --avalon8-voltage-level -5 lowest numbers 8500 hash at 950 watts runs very cool the 2 below did weird shit and acted like overclocks not under clocks --avalon8-voltage-level -6 --avalon8-voltage-level -8 Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 11, 2018, 06:57:02 PM Finally some down clock numbers that look okay
under more options this setting --avalon8-voltage-level -4 is using only 1305 watts Title: Re: Avalon 851 on its way. Post by: Steamtyme on August 11, 2018, 07:34:50 PM Wow that's a significant drop in power consumption; almost 1/3. Hopefully the hash hasn't dropped off to much.
Did you get any results at -3? And yay, it didn't fry another power meter. Title: Re: Avalon 851 on its way.

And yay, it didn't fry another power meter. okay at -4 --avalon8-voltage-level -4 settled in at 1260 watts on the corsair 1500ax tit model have to wait on hash rate to settle it is maybe 12202.40 and 1260/12202 is okay right near 103 watts a th that is spec as this is supposed to be a bit more power hungry I am going to add a second unit and see what happens. with 2 of three meters burnt out and 1 left I can only meter 1 unit not both 3 meters will show tomorrow I can post power use then. Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 11, 2018, 09:31:43 PM I deleted this info as it was based on the wrong idea about the 851
The Correct info is the 851 is a stand alone miner that needs your psu. IIRC this one has the psu built in somewhat like the Innosilcion Ok, so it must be close to the AvalonMiner 761 design. this was wrong it is just like the 841 and does not use a built in psu this was wrong based on an error Ok, so it must be close to the AvalonMiner 761 design. Was that the Chinese market only model they released? this was also wrong Was that the Chinese market only model they released? Yes. They sold it in Chinese and South Korean market only. I have a picture of it in my thread about my trip in Beijing and visiting Canaan. Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 11, 2018, 09:41:30 PM So I attached a second miner and did setting -3 and something is wrong.
Going to try -2 setting edit: the mm files were different one was older then the other they are now both the newest one https://i.imgur.com/GHUNo1I.png (https://i.imgur.com/GHUNo1I.png) both mm files the same and we are working! https://i.imgur.com/V6CW8Sp.png (https://i.imgur.com/V6CW8Sp.png) Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 12, 2018, 12:23:42 AM Okay I have this squared away for overnight test I am pointing two units to solo.ckpool
Using -2 offset. Doing about 24 th and cant measure watts on both units until I get a new meter. The 851 seems to be okay and a bit more power hungry on -2 I need new meters to be sure. Title: Re: Avalon 851 on its way. Post by: TheYankeesWin! on August 13, 2018, 12:46:39 AM Did the meters come today?
Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 13, 2018, 12:48:33 AM new meter link from amazon
https://www.amazon.com/gp/product/B07CKSTBX5/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 Yes I have been testing for about an hour. I thought of trying a different approach to clocking the volts. The new results are decent. They also bring about a new idea others may want to try. 1) on the stock settings of 0 the 851 hashes as high as 14.9t but uses insane power more then 1850 watts which kills most of my meters --avalon8-voltage-level -1 --avalon8-voltage-level -2 --avalon8-voltage-level -3 --avalon8-voltage-level -4 So I tried all of the above with the 841 and the 851 I like the results on the 841 but the 851 hashes lower and burns more power on those underclock settings So I started to think outside the box and opened a whole new world of clock settings ::) --avalon8-voltage-level -1.5 works which means many others like that may work my meters show 1350 + 1380 = 2730 watts that ls .13 watts at the wall or 130 watts per th at maybe 21000 gh which still sucks but room is hot 90f and it now opens clocks like -1.1 , -1.2 ,-1.3, -1.4 to testing many more for that matter. +1 to -4 by tenths is about 50 settings https://i.imgur.com/pQ7uVHF.png (https://i.imgur.com/pQ7uVHF.png) https://i.imgur.com/MsdvzUv.png (https://i.imgur.com/MsdvzUv.png) Title: Re: Avalon 851 on its way. Post by: TheYankeesWin! on August 13, 2018, 01:20:02 AM So the 851 does 14.5 to 14.9 th at 1750 to 1850 watts on stock setting?
Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 13, 2018, 01:26:30 AM @ yankees it does 14.6 to 14.9 at 0 setting but uses at least 1600 watts in a cooler room say 77 f
in a hot room 92f it pulled over 1850 watts on the hp gold 1450 psu it pull 1790 on a corsair 1500 titanium I shut that done asap due to fear of killing the psu I killed one kwatt meter as they like to do under 1800 watts on long tests. I did discover the -1.5 setting this has me under 1400 watts say 1350 to 1375 watts on each meter and around 22th \\ early tests show as of today If you want an avalon I would say buy the 841 .. the 851 seems to need more power as much as 1850 watts at stock in a warm room I am going to point the two to solo.ckpool and try -1.4 setting it does boot and does hash be back in 2 hours with a report. here are the 2 miners. I would hope for 22-23th at 2800 watts or better http://solo.ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje Title: Re: Avalon 851 on its way. Post by: minefarmbuy on August 13, 2018, 05:31:30 AM Looks like 21.3 th/s last hour from my read. Two 851's you said?
Title: Re: Avalon 851 on its way. Post by: philipma1957 on August 13, 2018, 10:17:26 AM Looks like 21.3 th/s last hour from my read. Two 851's you said? yep I just checked this morning. and with the -1.4 setting I am at 2820 watts and 21900 or .1287 per gh 128.7 watts per th now at stock or 0 I did push 14.9 and 14.7 which is 29.6 but that was with about 3700 watts that comes out to .125 per gh or 125 watts per th The psu needs to beefy to do 1800 watts I have a delta 2400 watt and a hp 2450 watt that will do it. the only case it makes to burn power like that is if btc moons to 12000 or more really fast also the units ran hot at stock. results over night: https://i.imgur.com/GqMkJ2E.png https://i.imgur.com/tojDIrI.png http://solo.ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje So far I prefer the 841 over this 851 but it is nice to find that numbers like -1.5 ,-1.4 do work to fine tune I will setup -1.3 now and test for 12 hours. Room is hot 90f -1.3 did boot I will get back with numbers tonght GAVE UP ON that setting it was about the same as -1.4 I am now on -0.9 and these are finally getting some where http://solo.ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje about 27.1 th and around 3220 watts in a 90f room that is 0.1188 a gh or 118.8 a th I taking these measurements to find a threshold -1.3 or -1.4 do 21.5 to 21.9 at about 2825 watts lets say .1289 per gh or 128.9 per th I am looking to get a steady 1500 watts at the meters or just under 3000 watts for 2 units may be the -1 or -1.1 setting will work best. based on my tests so far power cranks up but efficiency actually improved a tiny bit on this -0.9 setting. I ran the -0.9 for about 8 hours topped out at 14th x 2 = 28th https://i.imgur.com/rruEgwH.png https://i.imgur.com/0RVYO2s.png http://solo.ckpool.org/users/1JdC6Xg3ajT3rge3FgPNSYYFpmf53Vbtje I know I can push just a bit more. If I go to 0 my meters may burn as they did over the weekend. so 0.0 tested -0.9 tested > 8hours > 28072 gh 1710+ 1661= 3371 watts = .1200 watts a gh or 120 watts a th at 88f -1.0 tested -1.1 testing -1.3 tested -1.4 tested > 7hours > 21900gh. 1417+1398=2815 watts = .1289 watts a gh or 1289 watts a th at 86f -2.0 tested -2.7 tested >14hours >19300gh 1332 + 1309 = 2641 watts = 0.1368 a gh or 136.8 watts a h at 85f -3.0 tested -4.0 tested -0.9 has the best efficiency but runs hot at 43/92 and 39/88 with 100% fans. will drop to -2.7 now which did boot. going to do an 8 hour test I have some test limits I do not want to go over 1800 watts so 0.0 does that I won't be testing that setting again think 14.9 th and 1800-1825 watt in a warm room is close Title: Re: Avalon 851 on its way.

Post by: fanatic26_ on August 15, 2018, 08:27:21 PM .13 is horrible efficiency, why would anyone buy these?
The reliability doesnt make up for all that extra power being burnt versus the competition. I sure hope the 9 series lives up to its advertised specs, it would be nice to see Avalon not behind the pack on efficiency which has been the case the entire time I have been in this industry.

I can not tell people to get this over the 841 I can get 97 watts a th on the 841 So far I can't top 120 watts a th on the 851 even though I can go to 14.9 th with this one the 851 power 1750 watts I can do 13.5 th on the 841 power about 1400 watts Unless btc is to the moon that extra hash of around 1.4th is simply not worth about 350 watts of power. |
