here is how i got 400 with my 7870 (gigabyte 3x fan version)

core: 925
mem: 1375
voltage:0.987 (or 987 in msi afterburner)


cgminer settings:

--scrypt --thread-concurrency 16000 --intensity 19 -g 1 -w 256

just wanted to give a thanks for this worked well

I just got a new PC, built it myself from a kit:

APU: AMD A10-7700K Kaveri 3.5GHz Socket FM2+ 95W Quad-Core Desktop Processor with integrated AMD Radeon R7 GPU
VGA: PowerColor Radeon 7870 Ghz edition AX7870 2GBD5-2DHV4E, PCIe 3.0 // Memory: 1200 Engine: 1000

My settings in cgminer currently (NOTE: I am still tinkering with the settings as I just got this miner fired up 2 days ago:

--intensity 12 -T -g 1 --gpu-memclock 885 --shaders 1280
Kh/s with these settings: just a hair under to a hair over 300.

I can tinker the intensity to 13 or 14, but haven't tried about that. I can memclock at the highest of about 925...though 885-900 seems to be best for me. Anything higher or closer to 1200, and I lose an astounding amount of kh/s. I haven't really played with any other settings yet as I'm really quite pleased with my kh/s at the moment.

If anyone has any other advice, I would love to hear it.
