problem with x13
running r9 270

getting errors:
100 % rejected
invalid nonce error
Which pool? Is it really x13 algo?
I was testing it on nicehash stratum+tcp://stratum.nicehash.com:3337
Did you try a specified Nicehash miner:
https://nicehash.com/software/?
Note: darkcoin and darkcoin-mod represents x11 and x11mod (optimized), respectively; marucoin and marucoin-mod represents x13 and x13mod (optimized), respectively.
now moved to random x13 stratum pool
https://maru.suprnova.ccstill same problem, errors:
Invalid nonce count - HW Error
Rejected - Share is above target
skipping configuration option "kernel", invalid parameter set_kernel
Finally got mine to work (better late than never)
Had a type many lines down that I couldn't see on teamviewer ! Doh!
All the same, make sure you get the latest update for X13 - second link down on the op! could well be your issue.
sgminer.exe --kernel x13mod -o stratum+tcp://opc-stratum.pool.mn:7845 -u uername p password -g 4 -w 128 --thread-concurrency 8192 -I 20 --compact
Gets me 5Mhs on 2 x R9 290 (non x)
Will have to do for now.
X11 - I get 2.90-3mhs on each of my 290s with this :
-I 18,18,16 -g 2 -w 128,128 --thread-concurrency 8192 --gpu-engine 0-0 --gpu-memclock 0 --gpu-memdiff 0 --gpu-vddc 0.000 --auto-fan --temp-cutoff 92,92 --temp-overheat 85,85 --temp-target 70,70 --gpu-powertune 0
Hope that helps am still looking for the best perform for x13 i cant pass 2mhs if anybody have those settings for 290nonX for x13 please post it,
wait i just add this --compact and now each is giving me 3.50-370mh/s!
