name wrong ! chk properly.

I can understand wanting credit for every second participating in the pool, however, the Slush method isn't necessarily unfair.

It's true that you lose all your work on power down for the next block found.  But on the flip side of that coin you get full credit for the next block found on power up.  Granted, you lose work faster than you gain it, but not so much so that these two attributes of the scoring system don't nearly cancel each other out.

To boot, if you get back online before the next block is solved (in the pool) there is 0 impact to the credit towards that block.  So Slush favors power ons as well as intermittent power downs between blocks to balance out for losing credit on power downs where a block is solved.

I see nothing *bad* about that.  It's just different.

Love to try CKPool, but unable to connect for some reason.  Any suggestions?

I use Slush because I can have an active dashboard on every single electronic device I own.  I notice within minutes when one of my miners is offline or hashing at unusually low rates.  The increased % of uptime is worth more to me than the higher % of blocks found.

My units are in a remote location on a TWC business class connection and I still live in fear that they will burn up on an internet outage.  I've had several that I noticed immediately and by the time I arrived it still smelled a bit toasty and the metal racks were almost searing hot.  No other pool offers the kind of access to the dashboard (from my experience) that allows me to respond almost immediately.

Your HW errors are still really low though.   So the even with the 1 with more I don't see it as a amount that causes alarm.   You have a decent test run with over a day.   As far as hardware errors looks fine to me.


On another note Biodom can you add a PSU spot on your spreadsheet?   Would be interested to have that on there.  On one I am testing with you can put down the Bitmain AP3.

Blade 4 seems to have 10x the HW errors   -  Now hashing at 13.444Thz  -- Ambient temp is below 20deg C

Oh  and numnutz2009  your name is Fitting -- Just replace the first  n with a D

Slush is bad if you have a blackout  you lose your work.  I would not use them for this one reason. Forget any other reason then this one.

also along the same lines if you do a big rental  on nicehash and the rental drops off you lose your work.

I don't mine anywhere that loses my work  in under 12 hours.  To me the 5n feature of kano is a big reason I mine with them.

Can we have a non-emotional, fact based, discussion about that?  I am open to switching.

Slush is running around 62PH, it has a 2% fee and using a scoring system that seems fair (rewards consistent participation).  Transaction fees are shared.

CKPool is running around 36PH, has a 0.9% fee and uses PPLNSG payouts.  Transaction fees are also shared.

Seems to me, for someone that is running for months, PPLNSG and Slushes scoring system are similar in effect, both avoid block hoppers (are those still a problem?).

Variance based on pool size is not a big deal for either:  both are large enough that a daily payout is reasonable (my personal threshold).

Seems Slush wouldn't make for a very good backup pool, since short term access results in a lower score.  Seems to me that CKPool may be ok for that, although the payouts would be delayed by a day or so.

Bottom line, the fees are the major difference?

BTW - I have CKPool as one of my backup pools as of last night, but all three of my miners are showing the pool as dead.  I'm using a named account.  The doc indicates the worker name will be auto-generated upon first contact, yet I'll never have a first contact if the pool doesn't show up as alive...

it would be interesting to tally up S9 B1 performance so far. There seem to be some complains, but let's put some real numbers on this.
Please respond (if you want) with four  parameters. If machine is DOA, obviously zeroes for speed.

1. Th at start, for example 1hr without mhz adjustment (if possible)  
2. Stable Th
3. stable mhz
4. ambient temp

So far (of what was posted in bits and pieces):

Buddy, Slush's has the BEST dashboard, but CKPool has the BEST profits.

Being able to see the individual blades' performance opens up the possibility of combining good or bad performing blades into a single unit and then clocking the unit appropriately for the blades (presumably voiding the warranty in the process though).

@yxt have you tried downclocking at all to see what happens to the blades that are not performing as well?



Also out of curiosity, has anyone from batch 2 or 3 received a shipping notification?  I am curious if batch 3 really is going to ship before batch 2.

those chips temps are wayyyy too high my friend. your running some dangerous numbers. they should never go much higher than 70 degrees c at the chip and each day it runs like that it loses a little more life until it finally dies. if posible i would try fixing this sooner rather than later. i dont want your hardware throwin out that magic smoke.

first how m i supposed to know where the kid lives?? silly boy think before you speak

second he wasn't clear that's why i asked. there's no reason to assume ne one has 220v power and since idk him personally i didn't want to assume pay attention

third you obviously don't mine much. those that have would know psu issues do come up. for example some times a power supply wont power on one miner but it will work on another one of the same model. i had this happen with 2 s7's i have. the psu would work on every other miner i had except one s7. i tried like 5 s7's and all worked great except for one miner. i had to use a dps-1200fb that i modded as the supply for the controller. the psu that wouldn't power on that single miner was an evga g2 1300w psu so ik the psu was more than beefy enough to power on the controller besides if it wasn't all the other miners wouldn't have powered on either. so before you go runnin ur mouth kid ask. don't say my comments r useless because frankly ur ignorant negative comments don't help at all. i was at least offering a suggestion to him and others like him. what did u provide?? absolutely nothin! so take ur bull elsewhere please or be more polite to your fellow community.

maybe s9's are just arriving dead. i wasn't stupid enough to buy s9's at the current price and risk tens of thousands of dollars until things had a better roi but that doesn't mean i cant try and help people that need it which is more than u can say based on that ignorant reply.
