Title: Please help! kh/s different on cgminer to pool. High HW rate Post by: teddy56 on February 18, 2014, 03:51:29 AM I hope someone can help with this. I've no idea whats wrong...
Im using Windoows 7 64 bit and cgminer 3.5 and the following hardware Mobo: ASRock Extreme3 R2.0 Processor: AMD Sempron RAM: Patriot 4GB DDR3 1333MHz PSU: Thunderbolt 1200W Graphics: Gigabyte Radeon R9 290 I get a crazy high HW rate (100-3000) and a kh/s of 650-750 in cgminer when I use the settings below. In the pool a kh/s of about 20-100 shows up. setx GPU-MAX-ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer.exe --scrypt -o stratum+tcp://east-us.megamultipool.com:80 -u user -p password -I 20 --temp-cutoff 95 If I remove all settings and just use the below then I get HW:0 but a hash rate of 10 kh/s setx GPU-MAX-ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 cgminer.exe --scrypt -o stratum+tcp://east-us.megamultipool.com:80 -u user -p password If i reduce the intenity to 13 then I get a hash rate of about 400 kh/s and a HW rate in the hundreds.

You're going to need to supply the correct --thread-concurrency (and potentially other) arguments if you want to run at a high intensity, otherwise you get HW errors (as you've seen):
