10nm is a no go as that is just Samsung's version of TSMC's 12nm process (just as 14nm is Samsung's version of TSMC's 16nm). There would simply be no significant gain to justify the process R&D needed.

7nm? Eventually by the end of the year -- maybe.

Doubtful, in fact it better NOT work without a fan signal! Just search Amazon etc for a 'fan speed simulator' or 'miner fan simulator' for devices to provide a fake fan speed signal.

Just to keep the Record straight:
The company asicboost.com is NOT the 'inventor' of AB. They are a holding company that bought the AB Patent from Dr. Timo Hanke. The company was created to leverage the AB patent as a way to get IP rights from miner manufacturers by using what they call a "Blockchain Defensive Patent License". Thankfully so far they have failed miserably at that. btw: Their only listed Contact is through a Law office in Chicago.

Even Dr. Hanke is not the inventor of ASICboost: Many if not most parts of the AB logic processes and code were created by other developers (Kano is one of them) as speed optimizations originally aimed at CPU then later, GPU based BTC mining and discussed here in the Forum at least a year or more before Dr. Hanke applied for his Patent or published his paper. Kano has made mention of contributing such CPU/GPU code mods back in 2013 (edit: Citations needed). Dr. Hanke was only the first to publicly put it all together targeting it for use in ASIC-based SHA256 processing chips, have the concept (now being hardware-based) published in Academia as a whitepaper, and managed to get his version of AB Patented as such.

edit: Interesting -- I take it the original AB Patent has been revoked or at least suspended while being contested. Checking the AB site they now state that it is Patent Pending whereas previously when they and Halong Mining appeared on the scene back in November 2017 they unequivocally called it Patented. Even more interesting is that when you click on the link for their Blockchain Defensive Patent License, FireFox blocks it stating the site is improperly configured -- given the folks who are suspected to be behind that onerous, IP-grabbing patent license, their site attempting to do something shady does not surprise me in the least.

Same here. 5 orders from them so far, all arrived within 1 week of me placing the orders.
Ja. I am one of those who has gotten no notifications for the last 2 orders but again, everything came in on time based on previous orders.

Aside from the notification bug so far I am very happy with both Pangolinminer and the M10's I've gotten.

Ja. Best thing for Scott to do regarding sales is just use the sig space to provide links to his site like minefarmbuy does. As long as the post itself is on-topic and useful his post should be safe.

Something that would be interesting to find out is the exact relationships between microBT, Whatsminer, and Pangolinminer. Who actually owns the design? Who backs the production of the miners? Something miner owners who bought through Pango have to have noticed is that the sides of our miners have 2 large sticky areas where labels used to be - were those Whatsminer labels?

@offordscott, of course it gets deleted/moved. Being marketing information for your business that info belongs in <drum roll please> the Marketplace...

As for the drawn-out pre-order: No way am I doing that! While I have faith that the M20 will come in on-spec or at least close to it, after Canaan's A9xx flub I'd rather wait to see what the M20 actually does.

Try a CGMiner restart. After waiting for a 1/2 hour between restarts my sorta gimpy #4 miner usually 2x restarts, sometimes 3 to get up to full speed. For me SM0 is the problem child in Normal mode, Low-power mode is a no-go as SM0 and SM1 fail on the final reboot after tuning is done..

Hopefully it was just a small solder whisker or metal chip that shorted & blew. After Pango replies I would want to power down and open the PSU to look for the arc marks left. Most likely would be by the power cord inlet.

As expected my 5th M10-31 arrived on Monday and as was the case with my previous one, zero notifications from either Pangolin or DHL regarding the order status and shipping information. Checking my Pangolin account both the previous order and this one are still tagged as 'Processing' even though I have received them.

Anyone else not getting emails from Pango about their orders and seeing that their the order status is not being updated?

I would not call them 'older chips', it is just that the 16/14nm node process is fully mature and well characterized which means fully developed design rules leading to more predictable specs and much better & repeatable yields. The 12/10nm node has been in use long enough with enough chip production under its belt to be called a nearly-mature process. On top of that, the work being done on the 7nm node also pays huge dividends to advance the higher node production methods.

The 7nm node is still very much a work-in-progress for all Foundries. Even Intel has (again) pushed back on marketing the 7nm node.

To me @ the 58THs mark it rather depends on how many chips are used in it vs the M10S.
Compared to the M10-31 or 33 the M20-48 is a substantial improvement in speed/power.

On miner #4 I did do a ticket and they promptly replied was that order had been received and was processing. No emails followed. Several days later the miner showed up at work. Um, and now over weeks later for whatever reason that order is still tagged as 'processing' so Pango has not even updated their end to show it shipped and was received.

Not going to submit a ticket for this order (yet) as I have no doubts the same will happen with this one.

And once again - just as with miner #4, no emails yet from Pango or DHL. Based on times for the others around my order got a feeling that the miner will just show up on Monday... Pango had no problems sending a bunch of emails for the 1st 3 miners I got so wtf?

Considering this is the BITCOIN area where you posted, folks here could care less about mining anything that is not BTC.
Try asking in the Altcoin (Mining) areas to find folks who care.

When dealing with smaller countries also keep in mind what can happen when the government is corrupt/insane leading to infrastructure problems like Venezuela is having right now... https://www.wired.com/story/venezuela-power-outage-black-start/

^^ Ditto. I'm order #13343
Any emails from Pango yet on your orders?

The last M10 I got 2 weeks ago arrived with zero emails from Pangolin or DHL. The kicker -- looking in my Pango account that order is still tagged as 'Processing". Go fig.

So far it's looking like this order will be the same as I ordered on Monday and yet no emails of any kind from Pango...

Borderline shutting them down? Hell, I have 3 offline now and 2 of those are still in their un-opened boxes as the M10's I've been getting blow the doors of the 921's...

Do remember that the A9's are using bleeding-edge 1st-generation 7nm process tech. Given when Canaan did the layouts (middle of 2018) it is a very safe bet that they will need to respin the design to substantially improve on current results.

With the A9's it seems that when you upgrade the MM firmware you must also upgrade to the latest OpenWrt controller software. Different versions do not play together.

Around the LAN port? How about the ENTIRE miner is corroding!
Either it is/was in a very humid area or there are corrosive vapors around. Find out which it is and get the miners out of there before the PCIe power connectors and PCB traces start corroding as well...

The Avalons report what your PSU is feeding them. Check  Status > CGMiner API log. Near the top you will see:


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.
