Temps good.
Chain-4 (board 3) is on its way out.... Nice "Real Time hashrate eh? Wonder what BMminer is looking at  'cause it sure aiina right

I think this question has already been asked about 113 times in this thread, which means any given page will probably have the answer.

can someone pleas etell me what temperature is normal for S9 to hash on ?
for PCB and CHIP of course
thanks

I'm using a similar strategy. Diversifying helps to decrease risk.

ATM, I'm testing one of those new 150MHS X11 rigs that  can mine on 5 algos and uses very little electricity. A few the coins i'm able to mine have been around for a long time: ie Dash and Digibyte. I'm also researching a new/efficient  200MHS machine that can mine any GPU coin and uses only 800 watts.

My gut tells me that others are looking for more profitable/efficient alternatives to straight BTC mining.

So I hope BTC difficulty levels off. That way, I hope I'm able to keep existing last generation BTC gear (S7s and A6s) and the price of this generation's gear ( S9s and A7s) becomes a lot better. If not, there's always other mining gear opportunities to explore.

BTC mining gear manufacturers will not be the only "crypto mining gear makers" to make equipment in the crypto world....and some other coins will be around for the long run too. OFC, there is the same concern that happened to the Scrypt algo when Scrypt ASICs emerged.

TLDR:  As long as we can ROI under 8 months on any other equipment, my BTC mining gear purchases will take a back seat.

Those sold out quick

Nice temperatures!

i replaced my air condition to a powerful one 2.25HP
now i increased freq from 500 to 550 and free my fan from 100% speed to auto

Okay the Internet is a hard place to discuss  with an s-9 .
I can see your point in that bitmaintech doesn't care if miners buy gpus.
I have 23 gpus mining at about 500mh earning 900 usd and costing 430 in power that is 18 cent power
I net 470 usd per month.

I have 55th in s-9 it earns me money but has  free power due to solar array deal I have.
I can only lose on s-9 if it breaks since my warranty is 90 days.

So when I want to add gear I need to weigh the following  2 year warranty for gpu gear with the risk of all gpu coins crashing.

Or a 90 day warranty on s-9 which the risk of the s-9 breaking.

So I am middling my risk.

If the solar array was on my land and in my house I would have a few gpu miners running in it.

I can not see me going all gpu or all s-9 .  So I see  gpus and s-9 as different tools to dig crypto coin.

I also see all coins as the same item no real difference between them when viewed as a means to acquire wealth.  Obviously coins are consider different in other ways, but a million usd of any coin is a million usd.

With all due respect, I must disagree with the view of GPU's being competition for Bitmain. Using a GPU to mine a different coin, which is then exchanged for BTC isn't really the same thing as buying a Bitcoin miner. Yes it may be a cheaper way to acquire BTC, mining another coin and exchanging does nothing in terms of the network, difficulty, and the like.

To some extent folks that might have spent their money on a Bitmain product, maybe it has a tiny impact. If there was a wholesale rush to mine-XXX/exchange, folks with actual BTC mining hardware might benefit from a long term stability or reduction in difficulty. The value proposition also is at the whim of the exchange rate, and longevity of the the XXX coin. I always wonder what happens to all those XXX coins that are exchanged for BTC. Who gets "stuck" with them?

Besides, Bitmain doesn't seem to have any difficulty selling their miners at the price they want, regardless of what folks do with their actual fiat money (e.g buying a GPU based system).

Ok. I thought 3 hours was for the 650Mhz OC session.

I wouldn't consider 3 hours long term.

Ok, so you are long-term good with 600Mhz and ~12.93Th/s?

I've found it depends on temperature. The other morning it was 40F so my machines were running very cool. I turned one up to 650 it ran at 13.85 great for 3 hours. Temperatures here rose so I got nervous and turned it back down. I've never overclocked a s9 before so I am still very leary, especially while they are still under warranty. Except for the one I overclocked of course.

I had something weird happen.  Both of my S9's stopped hashing with 2 of the three boards.  I noticed the hashrate issue reported on the pool side.  When I logged into the first S9, most of the stuff looked fine except that two boards were showing 0 for real time hashrate and the overall RT hashrate was a third of normal.  I didn't think to make a note of the temps so there may have been a clue there as to whether the boards were using power or not.  When I logged into the second one it was almost the same story except that two boards had all X's on the chips.  I restarted cgminer on them both and thankfully everything came up fine.

So not sure if this was a network issue of some kind.  An S7 on the shelf next to them and using the same network switch had no issues.  Or if it was a power issue.  All 3 miners (the 2xS9 and the 1xS7) have the same PSU, EVGA 1600 Gold.  Considering both S9's were hit with similar malfunction at the same time I am inclined to think it was something external to the miners that caused it.

Also just for the record, restarting cgminer reset the found block counter so the miner that was erroneously reporting a found block (mentioned in recent previous posts) from before, no-longer shows that but it kind of kills the theory that the erroneously reported found block was from before a restart and the counter just hadn't reset.

is not

It appears Bitmain added Paypal to these new S9 batches now...

Interesting.

gpu's are the biggest competition bitmaintech has at the moment.

Is anyone here with the S9 11.85Th/s (550Mhz) -model overclocked to ~12.93Th/s (600Mhz)?
Is it running stable and ok with 600Mhz settings or do you notice instability in miner operation?

12mo; can we dream?
Incidentally, I bought 5 more GPUs while S9 was not on sale, a.k.a they have serious competition now.
