Reaper v13 Beta 4? Can I have gpu_thread_concurrency for one card?

That's correct, and the above config has it, 24576.  The other important thing to note is threads_per_gpu = 1 (7xxx series require this flag)

Yeah, sure.  This is my reaper config:

Code:
host ltcmine.ru
port 8344
user xxx
pass xxx


protocol litecoin

worksize 256
vectors 1
aggression 20
threads_per_gpu 1
sharethreads 32
lookup_gap 2
gpu_thread_concurrency 24576

Wattage is coming from the wall (AC power) from a Blue Planet electronic energy meter.  Rig idle without GPU is 70w, rig with 2 cards in mining BTC is 400W, rig with 3 cards in mining LTC is 750w.

Totally off topic: May I update https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison with your setup?

So, mining BTC at 520 MH/s on a 7950, I use 165 w/hr for every card I have (1.03v / 1 Ghz core / 300 MHz RAM).

Mining LTC at 550 kh/s on the same card, I use 227 w/hr for every card I have (1.03v / 1 Ghz core / 1450 MHz RAM).

So, presently, it's cheaper for me to just mine btc and use that to buy LTC.  LTC also heats my cards by at worst an extra 14C.

Are all the AMD cards like this?  Is the 6xxx series more efficient?
