What happened to the images in the top post?  They are all gone or blocked.

Yes, we found out early on that the Pi 3b drew more current than earlier models.  My Pi wouldn't boot when using the port on the R606.  So a separate P/S is required for Pi's.

I don't know what your hash rate is but if it is low then the pool may be setting you to a high difficulty, which is normal, and it may be taking a while for your miner to find the high diff share before it adjusts down to a difficulty more reasonable for your hash rate.


What do you mean by "mining.notify"?  I've never seen that message.

Sidehack, thanks for the ./ explanation.  That makes sense.  I'm just used to the DOS/OS2 convention to always look in the current directory first.


Are you still using Windoze?

Were you using a USB Hub, or are you plugging directly into the USB port?

Yes it's a good idea to have a backup pool or two.

But you are using the same pool just two different ports on that pool.  So that doesn't help for a  failover pool.


Not sure what the ./ is supposed to mean, I guess I should research that, but it's a requirement for Linux.  Glad your working now.  However it's still a mystery where that old version of CGMiner came from.

Your S9 has probably been running a long time though.  And you can always get lucky

What frequency are you telling the R606 to try for?  You should be able to do the stock 550Mhz on voltage level 4 and save allot of power.  I would shoot for a target of 750Mhz.

Are you using a USB hub?


What directory are you doing the "./cgminer" from?

Not knowing what you did it's hard to say what you did wrong.  I don't see how you could have followed the Top Post instructions nor mstroziers instructions, by using copy and paste, and ended up with 4.9.2.  I have followed both sets and have gotten the latest CGMiner each time.

I've not seen that command in any instructions.

Follow the official instructions in the top post or the more step by step instructions found here

From what I understand the odd versions are like betas and the even numbers are the supported releases.  I would go with the 18.04 LTS (Long Term Support) version.

Those look like instructions for building CGMiner.  But I don't know anything about Mac stuff.  Search through the thread, I think somebody got it to work on a Mac but I don't know how successful they were.

You would probably be better off using Ubuntu or a Pi 4.

You need to use the version of CGMiner VH made for the Gekko equipment which is linked on the top post.  Regular CGMiner does not work with the R606 or sticks. Also the version you are trying to use is ancient so it probably doesn't work with anything current.

Pay Per Share payouts are calculated per each difficulty period.  So PPS Pools payout less each difficulty period when difficulty increases or more if difficulty decreases, which is very rare.  PPS does not change each day.

So if the last difficulty period increased by 6% then that would account for the 6% decrease in payout.  Difficulty gets recalculated approximately every two weeks.

"--btc-address" is required for solo mining to your local Bitcoin client.  If you are solo mining to a solo pool like solo.ckpool.org it is not required since that is a pool and not your local bitcoin client.

Your R606 numbers look good and inline with what I get at power level 5 on my batch 2 unit.

2.  ASIC's have always gotten Hardware faults, that is pretty much a characteristic of ASIC's.  I don't even look at them anymore as long as my hashrate is decent, and yours is.

3.  You shouldn't need to worry about setting a minimum difficulty for any decent pool.  That setting is just so that an ASIC doesn't flood a pool with diff 1 shares before the pool adjusts to a reasonable value.  Most good pools start at a high value and adjust to a reasonable value that produces around 18 shares per minute. So don't worry about it and let the pool adjust it as the pool will do the adjustment regardless of what you set anyway.

5.  With Gekko gear you need to se VH's versions of CGMiner "."

Take the hub out of the mix for now, if that doesn't help with AB then try a test run on solo.ckpool.org as we know that supports AB correctly.

ASIC Boost is on by default.  There is only a command to disable it for pools that have an incompatible implementation.  You should see a + after the number of chips recognized which denotes AB is enabled.  Read the top post.

These links?  They work fine for me.

Why not?
