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.

now it makes more sense, thank you!

RX480 8G reference card gives about 160-165 with no bios mod

My sapphire Nitro OC + 8GB get around 176s/s stock bios, no OC on performance mode.

My MSI Gaming X's (again, stock bios no oc) gets around 162s/s.

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

Hello all
Can any one tell us 290x clock and memory settings to get best zec hash rate
Also I want to know 280x setting

My MSI Gaming X's (again, stock bios no oc) gets around 162s/s.

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.

I'll just sit back and wait couple days what will happen, then decide what to do

In the meantime you'll be losing some money because at this moment, for 4xx cards, ETH is 15%~20% more profitable than ZEC

Just go flip all the switches to the other bios....

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

For stock hawaii DPM4 normally works, add -100mV + mem 1125/ 1250 and you will see some nice power savings. Performance hit is normally 10-15% but that is not a problem with these profitability levels.

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

[ravikiranb1985]

try nanopool i increased earning about 10% on nanopool best pool ever and for 18000 accepted share there is 0 rejected shares

[chisefu]

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?

[forzendiablo]

for me v7 is least stabile. up to v6 i have been mining 24/7 withotu issue [windows] but v7 crushes my windows every 18-23 hours. i think there is some CPU issues on it.

[billU]

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
