THanks you! Its exact, I just added #xnsub and it work.

Can you explain what it does actually ?

extraNonce gets put into the input of the generation transaction. getwork clients can't see transactions, so they can't update extraNonce. Some miners instead modify nTime slightly to give them more nonce space.

extraNonce is used by bitcoind, but it's not part of the protocol. There is no extraNonce field in blocks or transactions.

With the newest S5 firmware you just add the #xnsub at the end of the settings. I have a S5 newest firmware and it works.

Settings
stratum.westhash.com:3334#xnsub

How can we do the Extranonce subscription with the new Antminer S5 ??

Thanks you

How do you enter the port number?
stratum+tcp://stratum.nicehash.com/#xnsub#skipcbcheck:3333 does not work.

KnC Titan users:

We suggest you to use #xnsub AND #skipcbcheck parameters to get stable mining on NiceHash or WestHash, example:

stratum+tcp://stratum.nicehash.com/#xnsub#skipcbcheck

With those settings you'll be able to get a stable 350 Mh/s average speed with fw 1.95 overclocking at 325MHs.

Proof:


btw: average NiceHash/WestHash Scrypt profitability is aprox. 25% more then direct Litecoin mining.

Are you 100% sure that you have all the algorithms configured with ALL your NiceHash / WestHash pools/profiles configurations?

You have to configure pools/profiles with blank password ("pass") parametere for all multi-algo algorithms with default parameters, or if you want to select only a subset of algorithms you have to set fX=0 to disable a particular fX algorithm.

Please take a carefull look at the configuration examples here: https://www.nicehash.com/index.jsp?p=multialgo#examples

If you have proper configuration then multi-algo will work 100%. The issues with "all multi-algo ports being down" is always related to sgminer misconfiguration (some algorithm missing).

There was crash of stats server. No coins were lost, only stats are broken. Hover your mouse over graph to see date and time of stats and you will see that stats are simply "missing".

I guess I answered my own question because after the difficulty change today, my miners switched away from WestHast and towards another pool because the difficulty change was greater than my specified margin of profitability. This happened in spite of the fact that WestHash was running at a very desirable 10+% over BTC at certain points today.

My miners would have stayed pointed at WestHast automatically if I had been able to specify the percentage of profitability over straight BTC mining rather than a specific BTC/TH/Day price. Instead I had to manually intervene, recompute a new constant taking into account the latest difficulty, and restart my miners with the new parameters.

I would love to just set and forget a percentage value that would keep my miners pointed at WestHash for as long as they maintain a profitable margin above BTC. Seems like this would be in the pool's best interest also for situations like today where the difficulty rises but profitability is still relatively good.

Nicehash, please consider adding the ability to specify a percentage instead of constant.

Thanks in advance for your consideration.

Is there a way to specify profitability as a percentage instead of as a BTC/TH/Day price constant?

As it stands today, if you want a constant profitability percentage threshold, don't you have to change the p=xxx parameter periodically after BTC network difficulty adjustments?

It would be nice to be able to specify something like this, to represent 4% over BTC, for example:

t=0.04
