Hello, guys  - I am new in mining and I wanna start with Zcash. I wanna use single GPU to start, and I wanna chose between Radeon RX 480 OR Radeon R9 280 or 290 - I need your advice and ideas.   Will it be beneficial with single GPU? And how much H/s I can get with the cards I mention above? (any close idea?)  thanks  480 will be MUCH more power efficient. dont get a 280/380. a 280x/290 will be the best $ per sol/s for now. 390 is like a 290, but better (IMO). but not better on price. I'd say get a 480 with civ 6, that would be the best deal for the long run. check out my site if you need info of all kinds on crypto mining ! Up to you, but keep in mind 280x and 290s werent doing much profit 2 months ago because they are power hungry, but right now they are doing profit. |

Claymore 280x (2048 cores) 1100/1750 -220h/s
470 (2048 cores) 1100/1750 -160h/s
30% That's very bad.
there's something called "core quality/performance".. Tahiti has been in the market since 2011, different improves in their releases (tahiti, tahiti xt, tahiti xl, tahiti superbigmac$5..etc) RX core (polaris) it's brand new...just few months since release. |

4 of cards show 135-136 H/s but the fifth shows 433 H/s and there are many rejects
What the problem with it? Can somebody explain me?

Did ZEC's difficulty just double? I'm literally submitting half as many shares than I was an hour ago with the same hashrate. Or is it just flypool?

Up to you, but keep in mind 280x and 290s werent doing much profit 2 months ago because they are power hungry, but right now they are doing profit. if you have to pay for electricity then choose the Rx - lower power consuption and better performance hash/w R9 290 are power hungry comparing to the RX gpus... Next are you able to buy a new r9 290 with warranty? also a point to thing about, coz if the gpu stops to work you cant claim it without the warranty...... also dont expect too much income from 1 card, it will make you some bucks at the end of the month (if you are free of any eletricity payment then it will be more..) |

share rate can flux but flypool is up to 15.6 MH before clay 8 flypool was at 12.8 MH |

This is the quote I was refering to:
"Memory bandwidth:
RX480: 256 GB/s
390X: 384 GB/s
ZEC uses a lot of memory operations. Do you still think that RX480 can work as fast as 390X?"
Reduce memclock almost twice to 1100 MHz on RX 480 - and you'll see that hashrate reduced only 200 -> 160 h/s. And Memory controller load still only 50%  |

share rate can flux but flypool is up to 15.6 MH before clay 8 flypool was at 12.8 MH FLY pool rised (finaly) sharediff from 1000 to 2000. So half less shares is same as before. |

When you say "finally" what do mean? I'm not trying to be an ass but how is this good? If I'm submitting less shares, I'm getting less of a payout, correct? Or am i missing something? |

all miners submitting less shares, so proportionately it changes nothing for you, but it reduces web traffic.

Same here, I could not understand it and then I saw they are showing the shares for less than an hour. Check the bars and you will see the time of each share count. Number of shares PER HOUR is more but they are counting in less than hour blocks ?? Why idk I was wrong, the less than hour count was only during transition in how the shares are counted 606 shares 2016 - 11 - 25 - 09:09 ( UTC - 06:00 ) 601 shares 2016 - 11 - 25 - 10:11 ( UTC - 06:00 ) 307 shares 2016 - 11 - 25 - 10:37 ( UTC - 06:00 ) 284 shares 2016 - 11 - 25 - 11:38 ( UTC - 06:00 ) 289 shares 2016 - 11 - 25 - 11:52 ( UTC - 06:00 ) 299 shares 2016 - 11 - 25 - 12:51 ( UTC - 06:00 ) same for everyone |
