Still not seeing it. I can see the L3+ but not the D3.



EDIT: Ah, I think I know where you mean now!

I notice there's a few Antminer D3s available on Ebay, perhaps not surprisingly with a whopping price mark-up:

Default Interesting article

There are more millionaires in world than there will ever be Bitcoins

Some good points there!

By the way, on the subject of Ripple and altcoins, I was just watching this video (in which Ripple gets a mention):

https://www.youtube.com/watch?v=Ce08yvu0Z1w

This guy is a bit of a shouty narcissist but he does do his research and I find he is often right in his predictions. I would recommend doing your own research too, but his recommendations are a good starting point to narrow down your search. Antshares/NEO was one that I bought a while ago on his recommendation.

He posts a new video almost every day. He also offers a cryptocurrency investment course that you can join for 10 if you use the link provided below the video. The course is about 40+ videos about investing in altcoins.

Another point they don't mention in that article: While there's a mining limit of 21 million BTC, which will take more than a hundred years to mine, you also have to take into account the 'lost' coins. Thousands/millions of coins have been lost already and every day someone loses access to more. By the time the 21 million limit is reached, I'd be surprised if more than half of that figure is still in circulation.

Here is D3 a bit cheaper but still more than double of Bitmain price. https://www.aliexpress.com/item/Bitm...AbTest=ae803_3

There is another SHA256 miner, the plus is that it's in stock but higher power usage and lower performance than S9.

I think I'd feel a little apprehensive buying either of those from an unknown Chinese seller on AliExpress.

That is quite inefficient compared with the S9. Looks like it does 11.5TH/s @ ~2kW, compared with the S9's 13.5TH/s @1.3kW. And yet they state "better than Antminer S7 S9" .... in what way is it better? Having said that, I suppose if they're in stock, and you can make you of the heat generated ...

My aim was to make something robust, easily repeatable, stackable and (reasonably) compact. I intended it as a 4-card rig but I've squeezed a 5th card into this one for now, which is pushing it a bit on a single 1200W PSU. There's room for a second PSU though if necessary.

It's relatively portable and easy to carry (guessing it probably weighs about 15Kg). The black acrylic sheet panels give it a little protection and, along with the rear (filtered) fans, help to project most of the heat forwards to allow it to be used as a space heater.

I've also added a WiFi adaptor to enable it to be used anywhere there's a power outlet. I expected poorer performance mining over WiFi but there seems to be negligible difference compared with Ethernet. I do have 3 UniFi WAPs in the house though so that probably helps.

The rig currently contains 4 x 1080 Ti cards + 1 x RX 480 ....
That'st one fine looking rig if a bit expensive but should last a long time and even in 4 years time those Ti's should be worth 100 each, very nicely done. I am trying to avoid extra fans to avoid extra power consumption and keep the distance between cards to keep them cool. I know it is not much saving 25W is only 2 per month but every little helps and I don't think a bit of heat is necessarily bad. I can see it reducing lifetime for electrolytic capacitors but capacitors on video cards are mostly solid state so not affected that much by heat and for the rest I think it's thermal cycling that causes failures i.e switching on/off and letting ti cool down/reheat that causes failures, not so much being at constant high temperature.

I also have WiFi on my 2 new rigs so that that they can be moved around the house to move the heat/noise . One has M.2 WiFi card, other USB stick. Both of them have M.2 SSD's . One of the motherboards I use have 3 M2 slots, one dedicated to WiFi and 2 general usage so I have one left free. I have M.2 to PCIe x4 adapter so it can taker another video card. This is running 2x Ti's at the moment as I have not made a rig to move them over to HP Microserver due to having quite bad cut to my finger but eventually when Ti's are moved and I get my pre-order RX580s it should run 6 of them.

What settings are you running on Ti's. I have mine on +150 core, +350 RAM and and 85% power, it gets me about 100MH/s on Skunk or a bit over 1400 Sols on Equihash.

I agree about M1, to be honest I was not that interested in S9 either before Bitcoin Cash but now it seems a bit of competition should at least keep rewards at current level if not increase and any possible future splits could add more competition and better/more stable rewards.

I do not have issue buying from unknown sellers on Aliexpress, I have been buying a lot of stuff from there and Aliexpress is like Escrow service. Seller does not get money until I have confirmed that I have received the goods in good order or until it times out without me making a claim. I have had a few issues including laptop motherboard costing over 300 which did not arrive and seller did not respond. Aliexpress returned money to me. There might be some warranty issues as I do not purchase miner directly from Bitmain but since D3 is not available from Bitmain and alternatives on e-bay are a lot more money I am definitely interested in the ones on aliexpress. It does say in the listing not to pay and to contact seller if interested in D3 which I have done to see what they have to say.
