Please i need to understand what make some GPU has more hashrates than others, from the following list of GPU features which exactly is the main responsible for better or high hashreates:
1. Core Clock(Mhz)
2. Memory Capacity
3. Stream Processors
4. Memory Speed
5. Memory Clock(Mhz)
6. Process:(xx nanometers)
7. PixelPipelines
8. Memory Interface: (128, 256 Bit or higher)
For Zcash I believe Memory bandwidth mainly RX 480 256 GB/s
R9 390 384 GB/sSecondly the Core Clock The microprocessor gives energy perfomance. Anyways someone can add more info.. Regards |

I would love to get some help mining. I mined years ago but it seems I have no idea what I'm doing anymore. I have tried every miner available and it seems I get the same error. I've tried different pools but alas no luck.
ZEC: Stratum - Cannot connect to eu1-zcash.flypool.
ZEC: Stratum - Failed to connect, retry in 20 sec..
I am running windows 7 64 bit, r9 390, Catalyst 15.12. My batch file contains:
GPU_FORCE_64BIT_PTR 1
GPU_MAX_HEAP_SIZE 100
GPU_USE_SYNC_OBJECTS 1
GPU_MAX_ALLOC_PERCENT 100
GPU_SINGLE_ALLOC_PERCENT 100
ZecMiner64.exe -zpool eu1-zcash.flypool.org:3333 -zwal t1UKaEoMka8CghGrsehTKMXR72jZZMrpTKr.1 -zpsw x -i 8
I would appreciate any help. I'm using the claymore miner v12.5 but I've gotten the same errors on other miners. I'm probably missing something easy but thanks in advance.
try set GPU_FORCE_64BIT_PTR=1 set GPU_MAX_HEAP_SIZE=100 set GPU_USE_SYNC_OBJECTS=1 set GPU_MAX_ALLOC_PERCENT=100 set GPU_SINGLE_ALLOC_PERCENT=100 ZecMiner64.exe -zpool ssl://eu1-zcash.flypool.org:3443 -zwal t1UKaEoMka8CghGrsehTKMXR72jZZMrpTKr.1 -zpsw x -a 0 -asm 1 -i 8 Make sure your firewall is not blocking the connection of ZecMiner64.exe Regards |

Running v12.4 ZEC on Win7x64 with 4 AMD cards - none show up with a GPU temp. The miner is hashing correctly, just not showing temp in Miner or Miner Manager. I have 15.2 downloaded, however the current version is 17.10
Do you think the issue is with the newer drivers?
I have the same driver on ETH v12.4 and the temp reports correctly, though it is running on Win10x64
Any ideas?
What I 've seen is that when you don't have a card connected to a monitor, the miner works although you cannot use all the AMD features (like MSI Afterburner).. Probably if you try to open AMD Radeon settings you'll see that cannot be opened due to there's any monitor connected. W10 64b ¦ AMD 17.3.1 (happened the same with previous versions..) Regards |

Also you might ping the pool's server, opening a Command promt and running for example:
ping zec-eu.suprnova.cc
you'll see if average is too high (above 350ms).
Regards.
350 ms is SLOOOOOOOOW. I can ping most servers across an OCEAN in 120-180ms. In my country within 100ms. I agree..I was wondering where the limit would be.. I'm using Antpool @200ms ping...and Suprnova (Europe) 25ms... How much would affect mining with a "lazy" ping? How could we measure that? |

For some reason I am having a ton of issues with MSI 390x on 11.x-12.3
I keep getting crashes and error messages about the 'GPU blocked from receiving data' in windows and 'returned faulty data' in miner. No idea why. 15.12 drivers, Win 10 x64
I have the MSI 390 (no X) and W10 x64. For me 15.12 works although gives pretty less sols than latest drivers.Currently using 17.3.1. Moreover, when I've got "returned faulty data" has been due to the voltage is not enough (trying to undervolt the card, specially the AUX vol, or setting the Memory Clock too high). Also you might ping the pool's server, opening a Command promt and running for example: ping zec-eu.suprnova.ccyou'll see if average is too high (above 350ms). Regards. |

bought a new desktop rig, not for dedicated mining purposes, just because I've come into some fat stacks, yo, Jesse.
Decided to go for a good value/on special Gigabyte 1060 6G, I run it along side my old GTX 960.HOWEVER - a few days earlier I was browsing around and came across an Asus Strix RX 470 - I was running a Sapphire Nitro+ RX480 4GB card along side the GTX960. So - new rig - 2x nvidia. Old rig RX480/new RX470. The RX470 cost me $190NZD - I'd just like to share with you how fkn impressed I am with its performance - pulling in consistent 260-290 Sol/s giving a total of 560 Sol/s+ with only minor Wattman alterations (stock BIOS's).  Moral of the story is - if you're not retarded and can undervolt/overclock and maintain consistency then $190 for the RX470 was a fkn steal.note: very high whilst typing this. please disregard over-analysis. -zpool stratum+tcp://zec-us.suprnova.cc:2142

-wd 1 Claymore says:
This miner is free-to-use, however, current developer fee is 2% if you use secure SSL/TLS connection to mining pool, every hour the miner mines for 72 seconds for developer.
If you use unsecure connection to mining pool, current developer fee is 2.5%, every hour the miner mines for 90 seconds for developer. So if you're using suprnova pool, I'd use ssl://zec.suprnova.cc:2242 Regards |

Can somebody please explain what's the difference between H/s and Sol/s that nheqminer shows?
Optiminer posted: Generally H/s and Sol/s are used as the same. What you care about is Sol/s.
The mining in ZCash uses Equihash. On each Equihash iteration a number of solutions are found. This is a randomized process though. Sometimes 0 solutions are found, most of time 1, 2, 3 but it could also be more. On average about 1.877 solutions can be found per Equihash iteration. Some miners might though do some short cuts which improve iterations per seconds but do not find all solutions per iterations, hence finding less than 1.877 solutions per Equihash iteration.
Optiminer shows both Iterations/s and Solutions/s. The profit you get from mining is proportional to the Sol/s, therefore that's what you should care about. The reason why optiminer shows both is that Iterations/s is more stable than Sol/s (and you can compute the average Sol/s as I/s*1.877) . Sol/s has a high variance due to the randomness in the process.

anyone noticed getting more rejects when using -asm 1 command instead of -asm 0
im getting ~5% rejects when -asm enabled and ~2% when disabled in my 4 x 390x rig
Can anyone confirm similar situation?
I'm getting ~1% rejects with -asm 1 MSI R9 390 BTW, I was wondering that using SSL server in order to achieve 2% fee I cannot use the server closer to my country (in my case EU), so maybe that's the reason. Regards EDIT: check pings to see if that's your issue ping zec.suprnova.cc ~26ms ping zec-eu.suprnova.cc ~28ms |

hi. how much sol with a r9 390?
310-330 sol/s OC : clock 1150 / MemClock 1550 / +50%Power / Core Voltage +0 (70 Celsius) about 208 watt  Regards |

Hello Claymore , could you add dynamic control of intensity from working miner for example by "shift +" "shift -" hotkeys ?
It would require reallocating GPU memory which will cause crash after few iterations, so I wouldn't like to do it. Why do you need it? Freezing the 6-RX480 (1100/1950 - 88mv) with -i 4 after start but ok with -i 0. PSU Corsair HX1000i. Have you try opening different instances of the miner ? It would be mining 2 GPUs, 1 min later another 2 , and 1 min later the last 2. You could adjust the intensity (or different for each instance) till your PSU gets the limit. Just an idea. -di GPU indexes, default is all available GPUs. For example, if you have four GPUs "-di 02" will enable only first and third GPUs (#0 and #2).Regards BTW, thanks Claymore for your work. |

Just received my New R-Box and very puzzling thing happens when I try to power it up, I have tried 3 different PSUs and when I turn them on I get nothing from the R-box and in all 3 cases the PSU dies instantly when I plug the Miner in hot. I suspect there is something wired wrong in the New R-Box but before i go rooting around in it I thought I would see if anyone else has had this issue. Thanks in advance.
I have read your comment and I was wondering if you could sorted it out. In my case I have been using 2 R-Box during one month without any problems and suddenly one of them turned off by itself. There is a short circuit inside so the PSU is not working with this R-Box connected. I cannot find which component is responsible of this. I have opened it and seems that everything is right. Any ideas? By the way, this one it was working at 128G average (cgminer @330Hz ver 4.7.1). Temp. 45-50 C. which component could cause the short? Thanks in advance. |
