Next miner update: http://coinsforall.io/distr/xpmclient-10.2.2-beta.tar.gzhttp://coinsforall.io/distr/xpmclient-10.2.2-beta-win64.tar.gzNo more invalid shares with odd targets (including target="11"), previous miners have 3-4% invalid share rate.
Remove obsolete parameters from config.txt
Add new parameter to config.txt:
# Maximal bit size of multipliers using with primorials 13, 14 and 15;
# Default values are 26, 33, 36
# Less values increases prime probability, but sieve generate less candidates
multiplierLimits = ["25", "31", "34"];
And also some useful hints for getting more CPD on different GPUs with target="11": Radeon RX VegasieveSize = "630";
weaveDepth = "36864";
multiplierLimits = ["25", "31", "34"];
Radeon R9 290 & R9 390sieveSize = "630";
Radeon RX 4xx & RX 5xxwindowSize = "8192";
multiplierLimits = ["24", "31", "35"];

why i get error "64 bit kernels not supported on 32 bit executable"?  i try different drivers. 15.2, 16.3 etc What type of Win10 you use, 32 bit or 64 bit ? |

How you did it ? why compiled win 10.2.1 version i can't find. extremal, is it difficult to do it? or you think all there mega programists? any body compile this, i lost a lot of time to try do it. mingw get error could not find protobuf
Compiled windows version is archive http://coinsforall.io/distr/xpmclient-10.2.1-beta.tar.gz name xpmclient.exe If you don't want use released binary and want compile, you need download and build google protobuf before and some other libraries mentioned in readme. To update statistics(target="11"):
Win 10
xpmclient v.10.2
Vega 56 (bios from wet 64), driver 18.2.3 - 0.66 cpd
xpmclient v.9.4.1
R9 390, driver 18.2.3 - 0.34(35) cpd
RX 480, driver Blockchain-Aug23 - 0.35(36) cpd
RX 580, driver 17.7 - 0.39(40) cpd
Vega and Polaris good results for target="11", I have stock Vega 56 with 0.61 cpd only  R9 390 too low CPD, I don't know how get 0.5 CPD with 18.2 drivers (may be run from separate directore and use old OCL?) |

Can you try xpmclient 10.2.1 with drivers 15.12 and OCL from 13.x/14.x ?
|
|
|
|
sure
What with shared kernel for 11ch ? |
|
|
|
can you make new superb kernel with target=11 for those cards? I can share this kernel, but everyone can do this. Best option for Tahiti/Hawaii (R9 280/290) is Catalyst 14.6, for R9 390 - Catalyst 15.12 with ocl from 14.6. please share that kernel. win10, driver 15.12, xpmclient9.4.1 with ocl14.6 simple fails to start. xpmclient start and close after 1 second. Can you run xpmclient from cmd terminal or make a .bat file with PAUSE command ? |

Hi, eXtermal, where can I find the source code for version 10.X? I want to compile it my own. The provided pre-compiled binary version hangs my PC which when I quit the miner (for playing my game). The github version dates back to 2014 and no source code for the new version. the old version no longer builts on modern ubuntu. 270 card 820/1250:
new miner < 3.2 cpd
9.4.1 < 4.8 cpd
7850 820/1250:
new miner <2.5 cpd
9.4.1 <3.7
difference 50%
for 9.4.1 driver 15.7.1 with ocl 14.6
for the new miner work only witout ocl driver in miner (15.7.1)
Miners 9.4.1 and 10.2.1 shows almost identically CPD with same drivers version. What's problem with xpmclient 10.2 on system with catalyst 15.7.1 and ocl 14.6 ? what if they stay at target=10? your pools will accept those shares or reject those shares? Pool will reject around 60% shares from miners with target=10, but continue accept blocks from it. can you make new superb kernel with target=11 for those cards? I can share this kernel, but everyone can do this. Best option for Tahiti/Hawaii (R9 280/290) is Catalyst 14.6, for R9 390 - Catalyst 15.12 with ocl from 14.6. |

thanks for the info. what is the reason that you forcing target=11 before difficulty reach 11.00? Difficulty also contains fractional part, it's a shares/blocks ratio. For example, with difficulty 10.0 all 10ch shares are blocks, with 10.5 - only 50% 10ch shares are blocks, with 10.994 - 0.6% 10ch shares are blocks. When you switch miner target to 11, it generates 60% less 10ch shares, but 10-20% more 11ch shares (depend on type of GPU). So, miner with target="11" will generate more blocks, than miner with target="10" at diffuculty >= 10.99x. |

xpmclient 10.2.1 is out http://coinsforall.io/distr/xpmclient-10.2.1-beta.tar.gzDifference from 10.2 is only target switch point, 10.994 now and it will not be changed. something is wrong on coinsforall.io?
cpd is raised and droped like crazy.
coinsforall.io pool display only sent CPD from clients. On xpmforall.org you can see true CPD in "24h Share Count". Sum of 10ch and 11ch is real CPD |
|
|
|
both of your pools count shares sended by clients so real CPD does not matter? Pool reject shares with wrong target (less than current difficulty). Without it, you can set target="6" and generate 81 times more shares without blocks. Why pool must pay for this shares? i was talking about valid shares, not interest in cheating. what i saw is that xpmclient 10.2 with target=10 generates more shares than same client with target=11 for the same difficulty. i didn't direct compare it with xpmclient9.4.1 but it seems that is better to force old xpmclient until EOL. See F.A.Q. https://bitcointalk.org/index.php?topic=831708.0What happens if I will use invalid target settings?
You will get less profit:
* difficulty < 10.994 and target="11": miner will generate less amount if shares.
* difficulty > 10.994 and target="10": big amount of shares will be marked as invalid.
When pool switches to "11ch" mode, it begin reject shares from xpmclient with target="10", because it's cheating same as target="9","8" etc. Now pool again in 10ch mode until 10.994 difficulty, best option now is using target="10" and wait xpmclient 10.2.1 release. I try release xpmclient 10.2 and switch pool to "11ch" at 10.991 difficulty, but less than 10% miners install xpmclient 10.2 or put target="11" to config.txt, all others continue using old settings. I decide that miners don't ready and make rollback. |

...and install xpmclient 10.2.1
it was already 10.2 .1?! Where? saw only 10.2 ... Most recommended miner is xpmclient 10.2.1 (will be available in 24 hours)how relevant is the text of "Primecoin mining calculator (1 Scrypt Mh = 15.6 CPD)"? Ohh, about 4 years ago Litecoin GPU mining was actual, overclocked Radeon R9 290X did 1000KHash/s in scrypt algo.. and 15.6 CPD on XPM. Now it's useless information |

@all: read this F.A.Q. please. If you have more questions, I will add it.https://bitcointalk.org/index.php?topic=831708briefly: set target="10", then wait and install xpmclient 10.2.1 - after this release no more changes in target switching procedure. Sorry for xpmclient 10.2 users, if more miners update their clients, you will not need change settings. both of your pools count shares sended by clients so real CPD does not matter? Pool reject shares with wrong target (less than current difficulty). Without it, you can set target="6" and generate 81 times more shares without blocks. Why pool must pay for this shares?
|
|
|
|
CPD pool dropped by 25% per day. Because some miners uses target=10 others target=11, pool can't show real CPD now. |

R9 390 must show ...................... 0.5 CPD with target=11 Maybe  9.4.1, target = "11", driver 18.2.3  off Интересно, в теме есть люди, не владеющие великим и могучим  18.2.3 not optimal for R9 390. Best driver for 290/290X is Catalyst 14.6, but this driver may not recognize newer R9 390 card. Usually miners use Catalyst 15.12 driver and AMD OpenCL dll from 14.6 in miner directory for R9 390/390X. Properly speed is ~14CPD with target=10 and 0.5x with target=11. Интересно, в теме есть люди, не владеющие великим и могучим For Russian support use PM or email from coinsforall.io website, here English only |

You can try 9.4.1 with target 11 and width 22 in config.txt
Not working, miner crashes at start... Screenshot please. what problem with miner - why speed low? Ok, it seems move to difficulty 11 is not easy Today I'll add a faq to first post at this topic and release xpmclient 10.2.1 after 1 day (at 10 March). |

RX560. 9.4.1 = 3.2cpd 10.2 = 0.05cpd this is normal? I'm in vain worrying? 0.05 cpd not normal, must be 0.11 CPD. You can try 9.4.1 with target 11 and width 22 in config.txt |
