I have problem with Claymore miner. With 3 GPU GTX 1070 8GB everything is OK and stable. When I add 4th GPU GTX 1070 8GB, miner starts to restart itself and giving me error CUDA ERROR 11 - CANNOT WRITE BUFFER FOR DAG. First I thought it's GPU fault and put new one with 2 old one and everthing is OK. Every combination of 3 GPUs is working, except when I add 4th one.
I increased virtual memory to 16GB and checked free disk space (71,6 GB).
I'm running on Windows 7 64-bit, with 4GB memory.
Could be problem in RAM or disk space ?
Please, for solutions, beacuse it's very little about this error on net.
I solved problem by adding 4 GB RAM (now total of 8 GB), but now I added 6th card and the same error occur? So 5+ GPU you need 16 GB of RAM ? Set 16GB minimum and 32GB maximum pagefile? |

Finally I can test and confirm that AMD has fixed the issue with slowdown at high DAG epochs for Vega/Polaris/Fiji cards. They are going to release new drivers in a few days.

You can still use two 1000w PSU's to run them so you are still kind of wrong  dual psus is dangerous had them catch fire before , crossing rails by accident I NEVER use dual psus anymore I see no issue to power cards from multiple 600 or 700W cheap power supplies. I am powering 6xR9 390 with six PS that in total, cost me app. 200$ and it works fine for months Important to mention that 390 in dual mining draws close to 300W each, 1800W total. You cannot get 2x1000W PSU for 200$ |

I run 5 x 1070 with 8Gb OS RAM (16Gb virtual memory settings). |

but if the new drivers are like 17.7.2 nothing works to set clocks/mem/pwr/temps/fans unless they fix this or a new claymore release works with new drivers. boysie |

Hi Guy's.
Sorry a bit of topic.
Just some info for the power usage for those not knowing, " I'm no expert"
To get some calculations done to know what you need,
you can calculate you Amp's with " P / V = I " -- " Watt / Voltage = Amp "
Watt = 2000
Volt = 120v (US)
Amp = ?
2000 / 120 = 16.66666666 Amps
Watt = 2000
Volt = 220v (EU/SA)
Amp = ?
2000 / 220 = 9.09090909 Amps

Will the new drivers increase speeds past what they were before the slowdown or will we be just back to where we were? Thanks! |

Watt = 2000
Volt = 120v (EU/SA)
Amp = ?
2000 / 220 = 9.09090909 Amps
VOLTS TIMES AMPS EQUALS WATTS-- The formula is stated " V x A = W", or, rearranging : "W = V x A", and further, "A = W/V", or "V = W/A". Sometimes, you will see electrical equipment rated with "VA" instead of "W". The term is identical. The important lesson here is that a 2000W load on a 120V circuit causes a greater flow of electrons through the circuitry. Quoting from academic.pgcc.edu/ent/ENT%20171%20Online%20Project/current%20flow.htm below: "Current Flow is the flow rate of electrons. One ampere of current is a flow rate of 6,250,000,000,000,000,000 electrons per second. As you can see, this is a very large number and the ampere (amp) is a large unit of measure." So, the greater flow rate in lower voltage circuitry results in more heat being generated as a by-product of electrical resistance. Is a BitCoin worth burning down an apartment complex? --scryptr P.S. -- 2000W in the USA is more than most household circuits can handle. An ASRock H110 Pro BTC with 13 FURYs, R9 280Xs, or VEGAs, with a triple PSU rig on 120V means you better have your BTC wallet on a thumb drive and can run faster than the fire. And the police, and the victims relatives. --scryptr |

but if the new drivers are like 17.7.2 nothing works to set clocks/mem/pwr/temps/fans unless they fix this or a new claymore release works with new drivers. boysie AMD changed ADL API again. I will release new version with Vega support and working fan control for 17.7.2 drivers (and higher) in 1-2 days. Finally I can test and confirm that AMD has fixed the issue with slowdown at high DAG epochs for Vega/Polaris/Fiji cards. They are going to release new drivers in a few days.
Will the new drivers increase speeds past what they were before the slowdown or will we be just back to where we were? Thanks! I don't see any speedup. Though Vega on new drivers generates ETH DAG within 2 seconds only. |

17.7.2 havn't speedup. They do not make sense for it. |

Hi Claymore and all
My cards are bios modded and i think i will have to patch newer drivers. I was using 16.x drivers until now.
Do i have to flash back ori bios first for install new drivers or just install the new driver, patch and reboot?
Great news anyway!

hello everyone.
PTPA and TS Claymore: off topic
I may need some advise from experts here, Im planning to build a new rig, what would you advise, GTX 1070 or should I wait for the trending VEGA? pls advise. Which one could give a better profit?
Thanks in advance!

hate to say it but profit is going down.. cheap cards hitting the market as everyone is selling off their gear. ive seen some rx 570 and 580 hit CL for under 300$ |
