780ti
*** sieve (performance) benchmark ***

Same problem as HD5xxx & HD6xxx, need another implementation of sieve. *** sieve (check) benchmark ***
OpenCL error: -54 at /HDD/build/projects/xpmclient/xpmclient/benchmarks.cpp:836
Hmm.. what driver version and config.txt you use ? Is there any chance for optimization in near future for Nvidia 750ti ? I don't know speed limit of 750Ti and other cards, I'll try find it. It's easy to make 2+ CPD with 750Ti (now only 1.75), I'll release new version with optimizations for NVidia soon. |

hozeThanks. I see that HD6xxx cards require whole kernel optimization, not only sieve  For compare, R9 290:

HD5970 shows good results on Fermat test, only 3.5 times slower than R9 290. I also intrest in benchmarks of old GeForce GTX 6xx/7xx cards, 980Ti and Fury X

Yes... Ati 5970 only 2.8 cpd  , 6970 ~2cpd Can you run benchmarks (xpmclient -b) and post results for 5970 and 6970 cards ? |

Can you explain with is different with this build? I tried it and I'm getting slower performance than with the previous version. I'm running 14.4 drivers. Thanks. What GPU you use and how much CPD you see? Can you run benchmarks (xpmclient -b) with versions 9.4.1 and 10.0?

XPM mining with 750Ti can be profitable after optimizations, if performance reaches 4+ CPD.. I think, it possible |

Port 6666 is open. Telnet connected. Miner also use ports 60000-60007. |
|
|
|
After starting the xpmclient_v9.4.1 hanging message: Connecting to frontend: xpmforall.org:6666 and nothing happens Port 6666 is closed at your network, check firewall. |
|
|

why xpmforall.org server is re-starting very frequently? This makes our workers less efficient. Because a blockchain synchronization problem when pool node works a long time with a very high block rate. Without restarting other miners (such as ypool) get too much orphans it's not good for primecoin network. With periodic restarting your workers lost about 0,1% XPM / day, not much? |
|
|
|
Why so few? in another pool with another miner obtained 5 times more.
Ypool scammers?...
Ypool is ok, but I see there too little block rate and a lot of orphans. I think, problem in original primecoind code.. after some hours work pool node (with very high block rate ~120 blocks/hour) begin send new blocks with delay 1-2 minutes. I have configured pool xpmforall for restarting every 4 hours, it must help ypool work properly at current primecoin network speed and difficulty. |

And have a miner for CPU Primecoin?
Yes, for other pools (ypool, etc). Difficulty too high for CPU mining now. Miner does not work

I think you use Catalyst 13.x, install 14.4 drivers. |
|
|
|
- Which driver will give me the best performance? Catalyst 14.4 - 14.7. - Can I also use a CPU miner while running this program? My experience in the past is that CPU miners really cut into the performance of GPU miners. Any tips for this? You can try and post results here. I hear my fans turn down and then up when new work comes in. Is this normal? The Claymore miner doesn't seem to do this. Normal time for getting new work equals ping to xpmforall.org: Work received: height=1107707 diff=10.828171 latency=39ms But sometimes pool answers to client with some delay: Work received: height=1107696 diff=10.828003 latency=212ms Latency more than 1 second is enough to decrease GPU temperature and fan speed. Use manual control for fan speed (line "fanspeed" in config.txt file). |

14.7 driver set 280X = 7.5 CPD How to get 10 CPD ? If you use Windows, you can try set GPU, memory clock and powertune with MSI afterburner, or try different catalyst version (14.6, 14.4). |
|
|

Hello. I'm using the 9.4.1 version of the miner. 8.1 Windows 64 Driver 14.12
I get 5.6 CPD to 280X (1100\1500) , config file by default. What am I doing wrong? Why such a low speed?
Use 14.4 - 14.7 drivers, 14.12 60% slower. I will add this to first post. |

on the calculator says 300 xpm, actually 2 times less. Why? 1. Too high orphan rate (more than 10%) last 24 hours (ypool and solo mining have same problem, low difficulty and high network speed). 2. Calculator uses 30/1 10ch/11ch ratio. Now 5433/150=36.22, -20% pool luck. I have checked payouts to other adresses, all have payouts ~calculator - 30% (some users have 170-190CPD and payouts 264-304 XPM). Now you mine 15 hours, but compare your payments with " XPM per day" value. The paid starting to increasing, bug seems to be a little slowly. Pool can't pay instantly with current block rate (1200 on xpmforall and 800 on ypool, normal rate is 1440 totally) can be 3-4 hours delay. |

These blocks are orphans on ypool, if you see blockchain, you find blocks mined by xpmforall.org |

Does it support Nvidia GK104 GPU? if so, do you mid for release first version to support Nvidia ?
GK104 not supported, miner works only with Maxwell GPUs (750Ti, GTX970, GTX980, Titan X). |
|
|
|
Hi, is there still plan to support Nvidia by v10?
I have unfinished miner for NVidia 750Ti / GTX970 / GTX980, but performance too low compare to AMD GPUs (~6 CPD on GTX970 and ~7.5 CPD on GTX980, it's 1/2 of R9 290X speed). |

where the wallet is downloaded? or working directly on the exchange?
http://primecoin.io/downloads.phpYou also can try use address from exchange (Cryptsy or other), it must work. |
