x11 mining help

[cmontanha]

Hi guys.

There is a problem with my x11 mining and ive been strugling for days to solve it without any positive result.

The problem is after a small amount of time, I start getting a lot of rejected shares (around 30%)

Will try to describe what Ive done:

- tried several miners. Im now using the miner provided in the DRK thread.
- tried without setting, setting only I (13,18,19,20), tried with full settings I found around the internet.
- instaled new AMD drivers (v14.14) (had 13.12)
- tried with only GPU at a time.

When does it happens? Always! No matter what pool im connected or what x11 coin Im mining. It always happens, always did.

Im using the right kernel and I always delete .bin after any change.

Ive noticed something weird too: sgminer looks freezed when it starts. Normally on the miner it has a "natural flow" of accepted / rejected shares going down the command line. In here it freezes for 2/3 mins and then it shows everything at once.

I dont know whatelse I could do so i would appreciate if someone could help me.

Thank you very much

All that was tried already. Tried several TC and memclocks

Right this moment the config that gives me less rejected shares (around 20%) is:

del *.bin
sgminer -k darkcoin -o stratum+tcp://XXX -p XXX -I 19 -w 256 -g 1 --lookup-gap 2 --thread-concurrency 8192,8192,8192,8192 --gpu-memclock 1500,1500,1500,1500 --gpu-engine 1175,1175,1175,1175

GPUs are R9280X from Asus

Thank you

Already tried g 2, g 4, w128 and the combinations between them

Does anyone have a mining guide for x11?

Mine configuration (-d 0 is 280X, -d 1 is 270)

Code:

color 0F
sgminer -k darkcoin -d 0,1 -o stratum+tcp://pool -u user -p pass --thread-concurrency 11200,21568 -I 13,19 --gpu-engine 1100,1200 --gpu-memclock 1500,1500 -w 256 -g 2,1 --no-submit-stale --lookup-gap 2 --failover-only -o stratum+tcp://poolBackup -u user -p pass

I have two powercolor 280x's.  Here's my stable x11 config.  The lower gpu engine one is Elpida and the higher a Hynix card.


c:\sgminer.exe --kernel darkcoin --auto-fan -I 19,19 --thread-concurrency 11200,11200 -w 256,256 -g 1,1 --temp-target 70,70 --temp-overheat 80,80 --temp-cutoff 90,90 --gpu-powertune 20,20 --gpu-engine 1010,1090 --gpu-memclock 1500,1500

Hope it helps some....

Both dont work. Looks like rejection town
