sooo, I´m running a Gigabyte r9 280x rev. 2 Catalyst 13.12

My Settings:

Code:

color 02
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
"D:\Program Files (x86)\Vertcoin-CGMinerAleks_NR3\cgminer.exe" --scrypt -o stratum+tcp://us.bitcrush.info:3444 -u -p -w 256 -I 13 -g 1 --lookup-gap 2 --gpu-powertune -20 --gpu-fan 59 --temp-overheat 85 --temp-cutoff 90 --gpu-memclock 1500 --gpu-engine 1100 --thread-concurrency 8212 (marginal difference in range between 8190 to 8250)

I am getting exactly 304.7 kh/s
with the normal cgminer I am getting about 730 kh/s

My problem:

It spits to many rejects out with an ratio of 12% (!!!). I tried playing with:

thread concurrency, no effect - 70% of 8192 = HW´s on mass

trying with -g 2 or higher was unsuccessful

lowering core clock resulted in lower hash speed (memclock the same)

lowering intensity induced lower hash speed

I really don´t know where the problem could be. Please help me Cheesy

The rejection rate is a catastrophe!

Problem solved. I changed the pool, now everything is running smooth!

What hashrate are you getting?

I have Gigabyte R9 280x, v3 my settings are:

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer.exe --scrypt -o stratum+tcp://s.la.vertcoin.org:3333 -u -p -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --gpu-memclock 1500 --gpu-engine 1000 --thread-concurrency 8192

And I am getting around ~300 kh/s - I'm used to seeing 720 kh/s. I've tried -g 1 and changing thread-concurrency but there's not much change. There are so many variables with this I'm hoping another Gigabyte user will share their settings.

Oh, I have underclocked the card, voltage set to 1.075.

Thanks!
