good kernel
you're talking about amdocl.* ?

of course. not every driver is good for every cards.
if you compile kernel on wrong drivers you will got bad results.
you can see my results in some older posts.

18.3.3 compute mode == blockchain driver == good result 0.42 CPD for RX 580 1250 MHz

you can do better, much better.
your compiled kernel is too big, it should be around 1193KB for better results.

the video cards are the same. changes only miner and difficulty.  Smiley



ps current CPD 0.70-0.75. constantly changing.

Hi, I have a problem with the GTX1060.
I have 2 R9 390 and 3 GTX 1060. The 2 R9 have all "Sher accepted", the gtx 1060 have continually "Invalid Share".

the Nvidia configuration file is this:
# Pool websites:
#   http://xpmforall.org
#   http://coinsforall.io

server = "xpmforall.org";
port = "6666";

# Your XPM payout address
address = "My addrss";

# You can give this machine a custom name
# Computer name is used as default
#name = "Nvidia";

# Platform:
#  "amd": AMD GCN cards
#  "amd legacy": AMD HD5xxx & HD6xxx cards
#  "nvidia": NVidia Maxwell cards
platform = "nvidia";

# GPU crash handling (properly untested feature):
# 0 - do nothing
# 1 - close miner application
# 2 - reboot system (need superuser rights)
onCrash = "0";

# - Valid cpuload range: 0 to 4
# - More than 2 does not make sense
# - You can use 0 for really slow CPUs
cpuload = "0";

# Target Cunningham chain length, default = 10
target = "10";

# Sieve size in stripes (1 stripe = 16384 bits), recommended 420 for AMD, 210 for NVidia
# Big sieve size gives more candidates with less prime probability
sieveSize = "420";

# Weave depth (primes number count using by sieve), recommended 40960 for AMD, 65536 for NVidia
# Big weave depth increases prime probability, but sieve generate less candidates
weaveDepth = "65536";

# Sieve layers number, optimal value is target*2, default = 20
width = "20";

# Sieve window size. Recommended values:
# AMD GPUs: 4096
# NVidia GeForce 750Ti: 8188
# Other NVidia Maxwell GPUs: 12284
windowSize = "12284";

# - The following settings have one entry per GPU
# - If you have more than 4 just add more entries or leave it as is to use defaults
# - All entries must be separated by commas and set between double quotes

# 0 = don't use device
# 1 = use device
devices =        ["1", "1", "1", "1", "1"];

# Primorial 13 is optimal
sieveprimorial = ["13", "13", "13", "13", "13"];

# sieves per round value, default = 5
sievePerRound = ["5", "5", "5", "5", "5"];

# -1 means don't change
corefreq =       ["-1", "-1", "-1", "-1", "-1"];
memfreq =        ["-1", "-1", "-1", "-1", "-1"];
powertune =      ["-1", "-1", "-1", "-1", "-1"];
fanspeed =       ["-1", "-1", "-1", "-1", "-1"];


If I put "sieveSize = "210";", the program closes automatically.

Why my GTX have all these "invalid shares" Huh??

Some people here talk about special kernels. I have good CPD on my Radeon cards, but how did some people get over 0.5 CPD per RX 580? I get 0.42 max.
Any suggestion are very much appreciated Smiley

I am not a large scale operation (10 GPUs only), so while it still matters to me its more of a thing that I wan't to optimize everything I can to the fullest. But if you mean if I am willing to pay? Well I can donate some ofc but not much. I am quite dry at the moment. If you want to share for the community then I am sure a lot of people will be very gratefull. But I will understand if you don't want to, so no problem.

Read first post before.
You cannot mine with target="10", difficulty > 11 now.

Anybody tested hashrate of R9 290x/390x on XPM with 10.2.2 tweaked miner ? May be ~0.54 CPD ?

I got 0.55cpd with Sapphire R9 290X Tri-X, xpmclient9.4.1

Yes, pool found new record, bi-twin chain of 15 numbers!
Block height 2592901.

Also, you can look details here: https://primes.zone (Cannot give direct link, website not support it.. go World Records, then click TWN).

No, because difficulty changed Smiley
With target=11 9.4.1 can work, but produce 4-5% invalid shares.

1 10ch = 10 9ch = 100 8ch = 1000 7ch.
Pools use PPLNS system, share cost depends on block value and total shares for last 1.5 hours.
