Topic: Innosilicon releases A9 Zmaster 50ksol/s Equihash miner at 620W - page 8. (Read 45686 times)

would someone have the balls and open their A9 and remove a heatsink of one of the chips and make a detailed picture of it? i would pay money for that. please PM me

I need past 3 months earnings of zec / day historical data with this miner.
For example from above links which i gave in july it was 0.53 zec/day , in august 0.41/day as per miners.
Need a chart which shows variation of earnings(in zec/day) vs diff of past 100 days
or
a data chart of past 100 days of coinwarz / whattomine predictions for each day.

Something like this that you are looking for ?
profitability calc vs BTC:
https://www.coinwarz.com/cryptocurrency
difficulty:
https://www.coinwarz.com/difficulty-charts/zcash-difficulty-chart
network hashrate:
https://www.coinwarz.com/network-hashrate-charts/zcash-network-hashrate-chart

So I think It's good so far, right ?

16h = 0.295 , 1h = 0.0184375 . coinwarz 1h (@40M diff) : 0.01688078

I set the threshold to 0.01 , Is it natural that the site payout so late ?

All of them are OK. and now It shows 54 Ksol for each a9 :|
About earning I dont know, must mine for 1 day ...
but for now It shows ( 16 H mining for 3 A9s = 0.295 zec ) , Is it good ?

Thanks for your help

I mined about 15 16 hours on Prohashing.

2 out 4 A9s once rebooted but not from full memory, I dunno why but they rebooted.

I have ping from prohashing about 190ms Average.

And average Ksol is lower than 200Ksols ( about 170Ksols ) ...! ( each A9 = 41 Ksol in the Prohashing   )

Who knows how to disable logging. Because A9 reboots after using full memory. it is not profitable. Maybe there's just nohup > "filename"

Thanks for the reply. Has anyone tried it and failed? From all the previous 49 pages , I think none tried to OC. Right?

Got two links where one says 0.532 zcash per day in July.
https://bitcointalksearch.org/topic/m.41862029
.41 zcash per day in August
https://bitcointalksearch.org/topic/m.43300417

Can someone post their complete day to day earnings from past 3 months of a single miner.
Do we have a inno chart or predictor tool or so to fetch historical earnings. Need it for a debate.

I think it's cgminer!
because...
/config/cgminer.conf

SSH
user: root
password: blacksheepwall

/var/www/webif/api/

and a lot of knowhow !

PLEASE do share if you find any solution !!!

Thanks for that. Got one more.
https://www.coinwarz.com/difficulty-charts/zcash-difficulty-chart

To summarize, from July ( release) difficulty has quadrupled (40 from 10) and profitability of this miner has become 1/4th (20 from 80) - this is rough calculation when converted to dollar which is not a very good way to calculate as price of zcash has tumbled from 400+ to 130+.

Do we have a chart of zcash coins ( on an average ) mined per day at 50 ksols/s ( i.e per miner) vs difficulty since July release.

What is needed to Overclock the A9?
What software is loaded? Cgminer?

Yea I know.
I mean I want to payout just in Zcash. Is it better than other pools ? Becasue peoples mine for example equihash and get btc for a fee.
In this case I mine equihash algo and paid in Zcash. Does it more profitable ? Or at least closest to the online calculators ?

So You say I give the prohashing pool BTC address and hold it ?

Hi
I switched to Prohashing.

Is it better than f2pool, flypool, zhashPro or other pools ?

I don't want any dollars or money, I just want to mine and hold Zcash. Which pool is the best ?

Thanks
