OgNasty, I would like to use your service for escrow to sell a Antminer S9.  Please provide your Bitcoin address.

Thank you!

PSU is not included, only miner is for sale.

I am located in the US and will post pictures tonight when I return from work.  MinerMedic is the highest bidder so far and yes, I would do escrow from a reliable source.

Hello all,

I am selling one of my Antminer S9's.  The miner has only two working hash boards and hashes at a steady 9THs.  The third board recently stopped reporting, though I will include it in the sale in case you wish to troubleshoot.  Looking for reasonable offers and will only accept BTC as method of payment.

Let me know if you are interested and please, no low ball offers.

Happy holidays!

Hello,

I did a very dumb thing and upgraded my 13.85 auto-frequency miner to Bitmains latest firmware.  Of course, as soon as the miner rebooted, it only had 2 boards hashing.  Did a little digging around and see that in the logs in mentioned that chains[5][6][7] have low pic voltage.  It then says that it is using backup chain_voltage - however, it is still reading one of my boards as having 0 asic.  At the end of the log, I believe it just ignores this last board and runs with the two it finds chips on.

I know this is not a board issue as the fucker was running great right up until I flashed the new firmware.  Errr... Help!

Is there any reasons why other miners are not joining the P2Pool?  Current hash rate for the pool is 1.5-2 PH.  Why are the bigger miners not mining here and what is the reason?

I would love to see the hash rate get back up again.

I am mining with now.  The hashing power has dropped from 12-14 PH to hovering at around 2 PH.  20 days to hit a block now 

I will look into solo.ckpool.

These are the only two pools?  I known Eligius paid out direct from reward.  Although, with WK being so absent recently, I won't touch that until it's fully back up and running.

This is exactly why I say a premium of 25% is.good for fresh coins.  

I am mining a bit of fresh Bitcoins and even at 25%, I am going to hang on to them.  Imagine 10-20 years from now the potential premium.

Sure would love to get some real feedback from knowledgeable Bitcoiners.  I personally believe that a 20-25% premium for fresh mined Bitcoins with no transaction history. 

To provide more support for my premium, take a look at BTCC - they were selling fresh mined blocks of 25BTC for 31BTC.  That is almost a 25% premium.

Some more knowledgeable input would be greatly appreciated!

Can someone explain the drop in hashing power pointed to p2pool?  I saw someone else mention it was up to 12PH and now it's hovering between 2-3PH.  Did I miss something? 

Everyone go back to a centralized pool?  What the hay??

You must be unaware that Bitcoins with no transaction history [" No inputs (Newly generated coins) "] are far more valuable than Bitcoins with previous transactions.

Please see image if you are unfamiliar with such coins = http://imgur.com/a/kS1Y7

" These coins will most likely appeal to investors primarily as a collectible, much like the first strike of a physical coin. "

“ Fresh Bitcoins are more limited in supply than used Bitcoins, anything with a limited supply usually gains in value. ”

" For collectors, the perceived advantage of owning fresh coins reflects the limited supplies. For others, new coins without transaction histories are more desirable than used coins with longer and unknown histories. A brand new coin has no ties to illicit transaction, and has never been stolen or used to buy illegal items, unlike coins used on the Silk Road. "

1 Bitcoin only equals 1 Bitcoin is that coin has had previous(long trail) of public transaction history.  The coins I speak of, literally are fresh from a Miner and if bought, the only transaction shown on the public ledger would be from "No Inputs (Newly Generated Coins)" to your Bitcoin wallet address.

What makes these coins even more scarce is the fact that 90% of the Bitcoin mining pools do not generated their rewards from the coinbase.  Instead, when a reward is paid to the pool, the reward is send directly to the pool operators Bitcoin wallet address and then from there distributed to the miners of the pools.  Good luck trying to buy these "Fresh Mint" coins directly from big pools yourself! 

Even if someone rented a rig, they would not get a ROI on renting.  Hardly get a ROI when buying mining rigs direct.  Thanks for spamming your rentals in my thread though.

Even when buying rigs direct, 90% of the mining pools do not reward from coinbase...instead, the full reward is sent to their wallet address and then they will send miners their shares from that wallet address.  If buyer would buy from those miners shares, they would be the 3rd transition.  You would have to buy directly from mining pools or miners who get rewarded direct from the coinbase.

Mining Pools chances are already have their coins sold before they are even mined.

Seeing as there are less Bitcoin with no transaction history, these are very rare.  I would assume a 20-25% premium is in the right range?

The buyer would have a trail from "no transaction history" to their wallet address.  Technically, the only history would be to their wallets address.

Hello,

I would like you input on a valuation for Mint Bitcoins with no transaction history.

Mint is offering fresh coins, has anyone bought from them¿

What would be a good premium for these?

Hello,

I remember awhile back I saw that someone with S5's(I believe) posted pictures of their setup.  They had removed the boards from their housing and placed them separately, mounted on a wall with a silent badass fan blowing at them.

Is this possible for the S9's or would they end up getting hotter?

Someone also mentioned to me that I should remove the boards and place them heat sink down on a sheet of aluminum foil to act as a larger heat sink, with fans of course.

Anyone tried either of these for the S9's or any asic's?  Any suggestions other than liquid immersion, water cooling, oil, more A/C would be most helpful!

These are in my home, inside with our air conditioner running about 73f, however, the front room they are in cannot keep up with their output(2 S9's).  I even bought a 10,000 BTU window mount which did nothing but add 100$ to my monthly electric bill, so that fucker is getting ripped out.  I plan on going through my A/C system tomorrow to see if there are leaks or some damper issues.

I forgot about this topic.

I ended up sending my bad board to BitmainWarranty and they fixed it, cost about $200 but it is running again.  I do get more HW errors than before, but fuck it...it is hashing.

Hello,

I am looking for an updated list of pools that payout directly from block reward.  Seems only one I know of is Eligius?

Please let me know if more.

Thank you

I just had board 3 stop hashing and is now only reporting 13 out of 63 asics.  While reading up on Bitmain forum it says I have encountered "Chain scission of chips" and to remove board to repair?  Has anyone else had this issue and how did you fix? 

Hoping I don't have to ship off for repair.

Thanks.

SlushPool,

Hypothetically speaking here, what is to stop your pool from artificially creating workers and the hash rate associated with them.  For instance, the pool has stayed at around 17,000-17,300+/- workers while the combined pool hashing power has gone up 10-20PH?  Would it be possible for a pool to artificially increase their ghost workers hashing rates up by 10-20PH?  Are ghost workers or artificial hash rates plausible? 

I do not know anything about the backend operations of a mining pool, just generally curious?  Is this something that could be done on other mining pools?  I love your pool, just a little worried about the huge increase in hashing power and not an increase in workers that I would assume would come with that big of a jump.

How can I be sure a pool is not doing some shady stuff or do I just have to believe the stats from the pool? 

Again, this is all hypothetical and I am just curious.  Some backend pool experts school me to some knowledge please.

Thank you Gentlemen!

I understand about the average hash rate.  What I am curious about is what is happening to the miner that raises the TH/s that high, even though its only 5 minutes and drops back to average.  I have a no fluctuations in electrical current, so what internally is making this happen.

I was hoping to get more feedback from the master electricians and hardware hackers.  What I am hoping is that if the machine can run at 20.03 TH/s for 5 minutes, then should I not be able to find/duplicate the action causing the spike?  Even furthermore, once found should you not be able to keep that action stable?

I also see in my Kernel Log that is showing two odd errors-

"Test Patten on chain[3]: FAILED!
Try to add 0.1V on chain[3]..."            

"Below ASIC's core didn't receive all the nonce, they should receive 8 nonce each!

asic[12]=908
core[058]=4   

asic[38]=910
core[023]=6"


How would I add 0.1V to board 3 and why do asic 12 and 38 not receive all the nonce?

Thanks for the help in advance!
