GPU Configs

Asus R9 280X
-v 1 -w 256 -I 13 -g 2 --lookup-gap 2 --gpu-powertune -20 --temp-overheat 85 --temp-cutoff 90 --gpu-memclock 1800 --gpu-engine 1080 --thread-concurrency 8192 --auto-fan --gpu-fan 60-100 --temp-target 75

I get about 390Kh/S

REMEMBER:

4 GPUS, at least 5-6 GB of RAM
5 GPUS at least 7-8 GB of RAM
6 GPUS at least 10GB of RAM

I have one right running 6 GPUs @ 12 GB; another 4 GPUS @ 4 GB (With the 5th GPU disabled). If I unplugged the 5th GPU all together, it will only let me run 3 GPUS @ 4GB. Yes, N-Scrypt is werid.

--thread-concurrency 8192 -g 2 -I 12 -Q 0 -E 10 --lookup-gap 2 --gpu-memclock 1500 --gpu-engine 1150
4GB RAM with 5 280x
each 280x got 150 Kh..

With similar settings, I am getting about 280KH/s on each of 4 R9 280x's. I think my issue is memory. I only have 4GB on that system. Maybe I need to add more RAM...

I have 6 280x on one motherboard and I have only 4GB of system ram. I get 370kh/s on all 6 cards n-scrypt, 750kh/s on scrypt. I am using --TC 8193 -g2. I also have 5 270x on one motherboard and still 4GB system ram.

can u please post settings including memclock and vdcc, and brand please. Cant get past 340 on my 4 r9 280 dualx sapphieres
