set difficulty for max combined devices Gh's or max per device

[bismuth]

my pool settings are currently set for difficulty 2 running 2x devices, each running at around 2.0 Gh's, since each share seems to be handled by only 1 device at a time -- is this the correct approach? or should I have it set for the combined rate of 4Gh's (difficulty 4)?

The way I understand the stratum protocol and desired Pool total network I/O coming from your location, it's recommended to set it according to total GHs power available to you on-site.

In your case (4 GHs), I'd set it to 4 then.

Wow I'm having the same issue.

At difficulty 4, I get a lower rate of accepted shares. Is this still advantageous in some way? Each share in cgminer displays either device 0 or device 1, its faster with difficulty 2.

On average, a difficulty of 2 will be accepted twice as many times as a difficulty of 4, but you get only half as many shares per acceptance, so it is the same.

excellent, thanks for that nugget of info
