If you are not seeing fan RPM the machine will not hash.

Beeping usually means there is an internet connectivity issue.

All of the current gen mining cards have a max thermal limit over 90c, why would you spend extra to overcool them?

You dont mine bitcoin with GPUs.

You dont post about GPUs in the bitcoin section.

You learn to read the stickied posts.

Since the heatsinks are held on with thermal epoxy, thermal paste will do nothing. Also, you will most likely damage your board cleaning the old epoxy off before putting the new stuff on so I wouldnt recommend it. These are not anything like computers in that way.

its not the physical controller that dictates if it is auto tune or not. That is all in the software.

If you are coming to America and refuse to hire American workers you should just turn right around and leave.

The companies are not going to come out and say they are having supply chain issues. Bitmains current stance is no new hardware until January.

First things first. A block of bitcoins is only 12.5 bitcoins, it has not been 25 for a long time.

Solo mining has a worse chance than playing the lotto to find a block with a single machine. You will just be throwing money away.

Comparing GPUs to ASICs is apples to oranges. You flat out dont mine bitcoin with GPUs, thats what all the other alt coins are for.

Also with just a single machine you can mine on dial up. You need almost no bandwith to run a miner.

Dont use nicehash to calculate profits. IMO dont use nicehash to mine bitcoin either. Nicehash is for lazy people that dont care about maximizing the money they make.

A brand new S9 from bitmain is around $1300, if you are paying $4000 you better ask for some lube while you get bent over. Also from a third party you get zero warranty. Dont do it.

The s9 will be around for at least another year, probably 2 before something usurps it as the most efficient miner available. If you dont pay some outrageous cost for them, you will make your money back. Even at a high residential power rate an s9 will make over $300 a month in profit and pay itself off in under 4 months.

the pagefile is a windows thing....and you cant run more than 8 of one brand of card in windows so literally NOONE will be tryin to run this board on windows with 19 cards

You realize the max for that card is 94c right? There is nothing you need to do, it just runs a lil warmer but still nowhere near any level that you need to worry about.

One thing you might want to be careful with. If you are powering 19 risers with that one PSU those cards only have to draw 35 watts each before you are really stressing the PSU. Thats 650w+ in just risers, plus the mobo itself.

As they say...it takes money to make money.

Bitcoin miners cant be hooked up to a monitor (unless you count the avalon RPi) and they dont have graphics cards.

If you dont have the stones to sit through the dips, mining is not the way to go. I have seen so many panic sellers when there is a drop in the market like we are seeing right now, then when it recovers in a week you are left holding an empty bag while everyone else continues to reap the profits. Mining is not a short game, you need to be in it for the long haul to realize true profits. Also, remember that not all of these coins work like BTC, some of them adjust difficulty dynamically so from hour to hour day to day the profits will never hold steady.

Take ZEC for example: When it is riding high at $300+ a coin the difficulty jumps and profitability tanks. When its low like now, $215 a coin the difficulty adjusts down. My rigs are making $75 less a month at $215 from $315 earlier this month if you just look at the USD value but if you look at the actual coin earnings im earning 0.5-0.7 ZEC more in a month then when it was higher. In the long run you can hodl more coins and realize more profits when the market ticks back up.

Have you tested PSU output with a multimeter to make sure power is getting to the motherboard?

See the link to find out how to turn the PSU on while it is not connected to anything.

You keep saying overheating but they are well within normal operating range. The thermal cutoff for those older s9s is 115c. Running them at 90c is right where they should be.

Also another thing of note, you can upgrade the firmware without going to the autotune. Bitmain has both static speed firmware and auto tune firmware available.

Dont disassemble a functional miner, you really should just leave well enough alone. You will 100% kill your boards trying to replace the thermal epoxy.

I run 480v down to 208v and we have the 208 transformer set to put out about 216v-218v at the PDUs.

There is no news because this is a useless speculation thread based on nothing but random guesses from people on the internet. There are no facts to support any of this.

Easily the best answer in this thread.

I would say step 1 is to at least give some info on your problem. People arent mind readers....
