Upgrading to 346.22 and 1.32 seems to have resolved the cuStreamSynchronize errors I was seeing in 1.31 / 343.22 when overclocking.

Tuned workload profile and the following overclock:

Code:
nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=250

nvidia-settings -a [gpu:1]/GPUGraphicsClockOffset[3]=250

nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[3]=400

nvidia-settings -a [gpu:1]/GPUMemoryTransferRateOffset[3]=400

best64.rule is not enough rules to gain full acceleration. try using d3ad0ne.rule or rockyou-30000.rule

Thanks epixoip.

With 150 clock offset and d3ad0ne.rule I am seeing:
Hash.Type......: NetNTLMv2
Speed.GPU.#1...: 294.4 MH/s
Speed.GPU.#2...: 291.9 MH/s
Speed.GPU.#*...: 586.3 MH/s

Bump it up to 200 offset and I get:
Hash.Type......: NetNTLMv2
Speed.GPU.#1...: 302.4 MH/s
Speed.GPU.#2...: 302.4 MH/s
Speed.GPU.#*...: 604.8 MH/s

Bump it up to 250 offset and I get:
Hash.Type......: NetNTLMv2
Speed.GPU.#1...: 309.8 MH/s
Speed.GPU.#2...: 309.6 MH/s
Speed.GPU.#*...: 619.4 MH/s
...
ERROR: cuStreamSynchronize() 714

I guess 200 is the sweet spot for these cards.
