Just point your bitcoin miner to a BCH pool and mine away

Why are you guys even considering these cards? I am really trying to understand it when you can just buy a gtx 1070 or rx580 and get 30mh at half the power draw

260-270 sols from an RX 470 is exactly how much they are supposed to hash with stock settings. I dont understand your question??

You can basically write off the money you lost, you will not get it back. Whenever you see a miner with rediculously impossible numbers you really should research before attempting to buy. There are only 3 real miner manufacturers out there.

There is a reason bitmain produced the R4. Their other equipment is not meant to be run at home but in a datacenter where cooling is more important than noise.

As far as putting a bigger fan, there is a reason the fan is the same size as the chassis. Putting a bigger fan on will just make things worse.

You literally linked the answer in your first post.

Right from intels site:

 Memory Types DDR4 2133, DDR3L 1333/1600 @ 1.35V

Theres really nothing to be done at this point.

Also as other have pointed out, with DDR4 there really isnt much of an improvement when you get the higher speed memory. I benchmarked my system with the RAM at 2133, and again with the XMP profile pushing it to 3200. There was less than 5% difference, its so negligible you would never be able to tell so dont fret over not hitting that 2400. The performance difference will be under 1-2%

your question is impossible to answer

1. You have to have a wallet per coin type, there isnt 1 wallet that does everything. It just doesnt work like that.

2. What do you mean by mining function? Wallets dont mine. Ever.

it is just a simple pass through setup. The fans all are covered like that because they are off. When you turn them on they blow the louvers open while exhausing the heat.

Older 54 chip S7s would burn like that all the time, and it was almost always when they lost network connectivity. If you have a very old S7 (first few batches) with very old firmware (which is why you should update your firmware) it could have caught on fire from lack of internet connection. It only takes a few minutes for them to heat up and burn themselves like that.

Im from California originally and I used to run 10kw worth of equipment in my garage. I was paying $1100-1300/mo in power and over the course of 3 years I never had an issue. The power company did not care as long as my bill was paid. The only thing they said was if it got shut off due to non payment they would require a $2000 deposit to turn it back on based on my usage. I only had PGE for my gas though, my power was through a local company.

Fair enough. I did learn how to repair the boards and have managed to reuse s7 chips on other boards successfully. The biggest issue is not knowing if the chip you are pulling off of a board is fully functional or not but it is possible with basic hand tools.

There is one piece you are missing. The PSUs draw say 6.5 amps at 208 volts on the AC side. A miner is drawing much more from the DC side.

If a miner is drawing 1500 watts from 12v thats actually 125 amps of DC current.


15 amps at 12 volts is only 180 watts.

wow I have never seen a machine with that number of hardware errors before. Something is majorly wrong. Have you tried mining on something besides nicehash? Everything else looks pretty normal.

Why would you buy a $55 converter when you can buy a proper server power supply for the same price that will put out 3000 watts?

Whatever you do, do NOT follow these instructions. This guy is giving his machine an EXTERNAL IP with his setup leaving it completely vulnerable and open to the public internet to be hacked.

The beeping is due to it not sensing internet. It can be a number of things. IP conflict, DNS issues, bad network cable, etc. I would verify all settings as well as swapping with a known good cable. Also you might want to factory reset the controller in cause something got borked in the configs. You can do this by using a toothpick to push in the reset button to the right of the ethernet port. Hold it down until you see both red and green lights blink at the same time and it beeps. This will put it back to DHCP so you can then find its IP, browse to it, and put all of your settings back in.

This is 100% false. Removing the heatsinks carefully is not all that hard. I can pull an entire board of S7 heatsinks off in 20 minutes without damaging the chips. The secret is to heat the smaller bottom heatsink and pull it off first. If you heat the larger heatsink it will pull the heat through to the bottom heatsink and melt the solder holding the chip in place, causing you to pull the chip off along with the heatsink in most cases. Also make sure you are not pulling straight up on the heatsink, twist a little when pulling so you are almost rocking the heatsink back and forth and peel it off slowly.

This is why you shouldnt run industrial equipment at home. Miners are NOT meant for residential areas, they are meant for datacenter like conditions where noise is not a concern.

I know it seems odd, but these mining chips do like to run a little warm. I ahve found that if I let the board temps get under 60c on the S7s they actually start to become unstable and crash a lot more than expected. Avalon 6 miners are the same way, under 60c and they see a noticable hash rate drop. I have personally found with the s7 that the sweet spot is 65-70c.

There is a key difference in the way you worded it versus the way he did. "Tons of availability" versus "availability improving tons". You can improve a bunch and still not be at a 'good' point....

As a matter of fact I would agree with him that aviailability is improving quite a bit. A month ago you couldnt even source AMD cards and now companies are finding that we can buy a few hundred at a time again since the mining SKUs went into production.

I am surprised so many people are recommending the kill-a-watt when in testing they prove to be inaccurate. The numbers can be skewed by +-10% with a kill-a-watt. Specifically with PC power supplies there are issues of it reading wrong and showing 100% efficiency. The proper way to measure your power is with an amp clamp on your power cord. You test the amperage then multiply it by the voltage to get wattage.

Say for example your rig is pulling 7.3 amps at 116 volts. With those numbers your rig is drawing 847 watts.

Test with 1 card, then 2, etc to see what your cards are actually pulling.
