I've been mining on a 5970/5870 trifire setup, overclocked 950/1200 and 900/1200, respectively. I have been using poclbm through GUIMiner and with the recent release of the phoenix/phatk kernel for that frontend, I wanted to give it a try. Here is a screenshot that I'd like explained:http://img823.imageshack.us/img823/7885/stales.th.png
You can see that there's a large difference between the stales produced by each kernels.
Here are my custom arguments:
-v -w 128 -f 1 (poclbm)
-k phatk AGGRESSION=19 WORKSIZE=128 BFI_INT VECTORS FASTLOOP=false (phoenix)
Poclbm produces something like 397/395/379 mh/s while phoenix is closer to 404/405/387 mh/s.
So, basically, my question is why does poclbm produces about 0.85% stales (on deepbit) over 200k stales while phoenix is closer to 2-4%?
While we figure this one out, I'll keep using poclbm. 3% higher rate is not worth 3% higher stales.
