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" ??
