I know this had been discussed a lot, but can someone clarify to me one more time why my rigs hashrate is less on coinmine.pl then the real hashrate miner shows ?
because pool determines your speed by shares submitted and pools always fluctuate so 1 sec u might be way higher than u have next lower but usually it avg the same Thanks now I kinda got it... What will be the avg speed of RX480 8G ? 175-180 H/s

Think of the local hash-rate displayed by your miner in the same way as you would your optimistic MPG readout on your car. Say you have 1 gallon of gas left in your tank, your car's readout is showing you are getting 30 MPG and the nearest gas-station is only 25 miles away. According to the local readout your should be fine as you only need to go 25 miles not 30. However, the car's computer does not see the big hill you have to climb in order to get to the gas station, and that hill will temporarily drop your average down to 15 MPG, meaning you will only be able to drive 22 miles before running out of gas. So if you turn your mind-set around a little and view the pool as the real hash-rate, and what your miner displays more like that car readout, you will be more likely to have better results as the pool takes into account real world factors such as stales, latency, bad (or good) luck, pool maintenance, etc.

THX for this very good explanation. Too bad that very few people will read it.

My bad is that I modded most of my cards for ETH low power mining with avg 29.4mh/s. There are 266 RX480 8Gs to remod for ZCash from that low pow mod, only few are left on their stock bios and those are the ones with the highest hashrate at the moment. I don't know when I'll have to get back to ETH.

Mostly it is the "ping" towards pool's server that causes this.

Performance hit is normally 10-15% but that is not a problem with these profitability levels.

Mostly it is the "ping" towards pool's server that causes this. Last night I was having ping of 68ms and accepted share as high as 25 seconds. Coinmine is for sure having bandwidth issues. Perhaps not enough threads on the server to handle the requests. On average it's taking me around 300-400 ms to accept a share. My internet access is via my mobile phone but if that was the cause the ping would suffer as well

Ahhh the dilemas of being a miner, so many programs to keep track of, so many power mods for individual algorithms

So far I have been mining since 7.0 launch with 16 gpu's and it hasn't crashed, right on! Is the Optiminer Linux version just as stable?

Dear Claymore. Thanks again for a great program.
Question please. Should the start.bat file for the Zcash miner use the SET or SETX at the top before each GPU_**** statement?
Thanks in advance
