i have a very old HD7790 cards this piece of sheet  gives ZEC: 12/13/16-02:29:46 - New job from zec-ru1.dwarfpool.com:3333
target: 0x001ffffc (diff: 2048H)
ZEC - Total Speed: 171.054 H/s, Total Shares: 10100, Rejected: 70, Time: 48:54
ZEC: GPU0 85.628 H/s, GPU1 85.425 H/s
works perfectly on miner v9.1, win7x64, for 2 days w/o any troubles.... https://en.wikipedia.org/wiki/Radeon_HD_7000_Series1000mhz cpu, 1500 mhz memory and only 896 cpu units. one card takes 40w and another one 60w. so i guess 200-250w per system with 2 this cards. and you can compare power to rx480 with 1266 mhz cpu, 2250mhz memory and 2304 cpu units. in all benchmarks (WPA (56/200mh/s), FAH (50/250 PPD) etc) each rx480 gives about 3.5-5pcs of hd7790. if ETH i can't get the hashrate because my cards is 1 gb, but on the net there are digits like 5-6mh/sec, so its 31/6=5.1 times... and only in ZEC each rx480 gives 200/85=2.3 pcs of hd7790. so, this digit looks very sad, like theoretical 2304/896=2.57 pcs.... i don't know why hd7790 works so good to compare to rx480, may be a very good core code for hd7790, or may be a very bad code for rx480, or may be i'm totally wrong in all  Have to try my 6970. 7770 is doing 70 with v9 |

EWBF miner 300 h/s 1080 61 C.... total power 73 %
So what...? With the price a 1080 cost I could get 3-4 rx470 so 600 to 800 sols/s  1070 can do 310 sol with 100watt, or 370 sol with 150watt, that is better than any amd out there, i'm still laughing thinking that there are poeple that believe amd is better... This isn't brain surgery, rocket science, or even algebra. It's simple division... Card Hash Rate Wattage Cost Euro/Hash R9 Fury 300 H/s 150W $260 $0.86 1070 370 H/s 150W $400 $1.08 Keep paying $1.08 per hash, I will pay $0.86. You have not specified the right price Fury graphics cards. In the same shop in Germany graphics cards have the following price and price / performance is as follows: Card hash rate power cost $/Hash R9 Fury (Sapphire Radeon Nitro R9 Fury Tri-X OC+ ) 300 H/s 150W 346 Euro 1.153 Euro 1070 (Manli GeForce GTX1070 Ultimate) 370 H/s 150W 419 Euro 1.13243 Euro 1070 (ZOTAC GeForce GTX1070 Mini) 370 H/s 150W 443 Euro 1.197 Euro 1070 (Gigabyte GeForce GTX1070 Windforce OC ) 370 H/s 150W 459 Euro 1.24 Euro However, not all nVIDIA 1070 to hashed 370 . Sol / s. My EVGA can only 350 Sol/ s and a very overclocked. Still think the 7950 give you the best roi doing 220 hash for $50 and 180 watts overclocked. |

Guys, which pool is better for mining ZEC? (I'm in east EU)
I'm thinking between Dwarfpool and Flypool. Probably some other (Nanopool, Suprnova or else)
Tell me, pls.
Dwarfpool is too small - yet. So I suggest you to use Flypool or Suprnova. It seems that speed is higher on Dwarpool. Has anybody compared profitability between Dwarfpool and Flypool/Suprnova? On flypool is impossible to audit the shares sent so you can only audit the rewards that in my case failed to meet the expected ones. The hash rate they report goes all over with 10% on the high side and 50% on the low side. I would expect it to be the same on both ends with a middle point around the miner reported hash - dev fee. |

Then why the 2% offer? Well... maybe Claymore is SO concerned with user's security that he offered them discounted fee? Win-win for both Claymore and miners! On the other hand if Claymore is so concerned with miner's security he can release his software open source and people would still pay fees regardless especially considering: I expect to lose some money. It's not a problem for me I have been selling various software for 15 years in different ways so I have some experience. Unfortunately, open source does not work. No kidding. Been there done that. You publish your software and one way or another is going to be used elsewhere for a profit |

Hey Claymore , What would be a good place to learn how to code in general and how to code for miners in specific? Can you please guide. May be jsut 1 or 2 things that I need to get started. Thank you Go to msdn.microsoft.com and download the free version of visual studio. After go to YouTube and watch videos on c# c++ and open CL. In a few years you can write a miner |

SSL was implemented long time ago for mining already but was removed again due to the increased network lag.
Lags can only create a pool if it spends a lot of time to encrypt/decrypt data, am I correct? SSL connection is based on same sockets and it takes almost zero time on client side to encrypt/decrypt 1Kb of data. I'm curious about server load, is it too expensive to use encrypted connections for you? For me? No, not at all but as said before, I've never heard of redirected or attacks (mitm) for miners traffic it's no problem for me that you're using ssl for securing your miner against no fee wrappers etc but IMHO you should just say so - I believe most people won't have an issue with it Man in the middle doesn't care about encryption lol. Very easy to implement. No need to write network drivers. For the miner the mitm is the pool that can decrypt the packet and forward it to the actual pool. |

Dual-X R9 280X 3G D5
win7 4 Gb RAM, 16 Gb virtual RAM
radeon software ver 16.9.2
zecminerx64.exe -zpool ssl suprnova -i 8
hashrate avg 200 h/s
hashrate do not match between pools and my rig
and always : share rejected 5
is this normal ?
Yes. Pools steal shares from you. The only zcash pool that reports and pays correctly what is expected is dwarfpool. that's quite the rabbit hole you've started your way down.not that i don't agree. we are executing closed source code written by an anonymous author that is coincidentally named after a device that sits idle until activation at which point it explodes and wreaking havoc all around it. that author is being payed handsomely for this privilege. funny how a few shills and largely clueless mining community can lead up to the current state of things. We have a contract with claymore. We know how much we are paying. We have a contract with the pools that most don't give a crap about it and steal shares on top of the 1%. On top of that flypool generates a ton of rejects due to under performing server. It costs the miners around 10%. |

Thanks is it easy to start useing dwarfpool i use flypool now how much are them takeing can you give me a little guide to use dwarfpool? sorry for my bad eng Only issue is you will make about 1/2 as much right now on that pool than zpool because it is so small. I like dwarfpool but man not that much =( You don't make based on the pool lmao except that you may not make based on the pool honesty. Coin mine and flypool are stealing shares plus a 1% plus of rejected shares. I started this miner 7 hours ago on dwarfpool and have 1 reject on 2607 submissions. The reward is in line with what would be expected of 470 sols |

Ok, you miners can't read:
reduced devfee, it's 2% now (72sec instead of 90sec) if you use secure SSL/TLS connection
After using the SSL/TLS, the share rejection is 1.0 to 1.5% now. The rejection rate was 0.3 to 0.5 previously. my reject rate, with ssl, is 0.71% and 0.83% on my two rigs. more or less what it was before. People don't understand that a rejected share is one that cross with a new job somewhere along the way. If the pool is slow processing incoming shares you also may get a reject. My rejects were around 1% at flypool going as high as 3% with timeouts that are frequent there. On the other end at dwarf the reject rate is 0.2%. So before blaming the miner you should be blaming the pool |

v9.1:
- additional range checks in code for better stability.
- reduced devfee, it's 2% now (72sec instead of 90sec) if you use secure SSL/TLS connection, currently Flypool and Suprnova pools support encrypted connections, see Readme for samples.
- improved "-di detect" option: now after GPU order detection miner starts mining with the detected order.
- added ability to use environment variables in "epools.txt" and "config.txt" files. For example, define "WORKER" environment varibale and use it as "%WORKER%" in config.txt.
The power spike is associated with a drop in GPU load and memory control load, as reported on gpuz. Is the driver doing some sort of cleanup ? |

Hola, Soy de Venezuela.
Minando. Energia electrica barata (gratis) 0.001$ al mes para toda la casa.
Claymore's v8.0 r9 380 stock 129.9H/s
Claymore's v9.0 r9 380 stock 158.9H / s
volvi al v8.0.
El v9 inestable. cuelgue cada 12 horas o antes.
lo siento por mi mal ingles (google traductor)
___________________________________________________________________
Hi I'm from venezuela.
Mining. Cheap electric power (free) $ 0.001 per month for the whole house.
Claymore's v8.0 r9 380 stock 129.9H / s
Claymore's v9.0 r9 380 stock 158.9H / s
I returned to v8.0.
The v9 is unstable. Hang every 12 hours or before.
Sorry for my bad english (google translate)
It's a bit strange, I'm running claymore's zec v9.0 without any problems ( I have the same cards) It could be a PSU issue  Been mining non stop on a bronze 650w power brick using a oc to the max rx480 and a 7950. In my humble opinion v9 uses more power and for whatever reason spikes. Also on my 480 card vdcc is not stable. On the 7950 everything is stable but not so much on the 480. As I see an unstable memory usage , memory allocation could be at fault either on the miner or on the driver that may have a memory cleanup routine for the Rx family. I really don't know |

I need advice about pool, at the moment we are mining on coinmine.pl, all online calculators are saying that I should get 6.6 zec a day, but I got only half of it, I'm aware that this is the mater of many factors, but I know that something is wrong, your advice would be much appreciated
dwarfpool.............read my earlier post about it You posted that coinmine.pl paid for 830h/s and dwarfpool paid for 1100h/s when you rigs avg was 1080h/s. It means I should switch to it right ? sorry for obvious questions but I'm sleepy as hell been awaky ~28 hrs Coinmine I've been aware for awhile. That's why I switched to flypool only to find the same anf very unstable. As with coinmine flypool also reports 10% under. Testing dwarfpool now and so far do good. |

Yea. The spikes are quite real. One of my pc's has a 730w psu powering a rx 480 and a 280x. This combination has been running stable for months without problems (even eth/sia dual mining). A few minutes ago, the pc rebooted and said "a power surge was detected - press F1 to continue". There is nothing else running on the system except claymore v9. On the 7950 everything seems to be stable but on the rx480 is all over the place. On gpuz the normal is 120 but the spikes go to 212. I also noticed the memory usage is stable on the 7950 but goes up and down on the 480. Same with usage. No valleys on the 7950 but deep valleys on the 480. I think the power spike maybe related to this memory management. What do you think claymore? |

After some tunning now doing 247-253 on rx480.
1420/2195 +20% power
7950 tuning - 205 sols @ 1050/1375 What watt usage do you see on 7950? No idea it's helping heating the apartment lol . The numbers I've seen calls for 150 watts, so maybe 170 180 with the over clock. |

Sapphire Nitro Rx480 8gb 255h/s . You are the best Claymore.
how do you get 255 ? I get 222 on sapphire nitro 480.. Do you have bios mod ? Try 1420/2195 |
