Hey there!

Could anybody please explain to my why I get fewer rejected shares when lowering intensity? I'm running a 6 card setup with 7950's and 1080MHz/1250MHZ clocks, cgminer 3.7.2 @ I20. When pool-mining - I figuered out that rejected shares are only produced when a new block is found. Then I mostly end up with a rejection rate of 06%-10%. I've tested like 10 pools now. Latency does not seem to be an issue.

Now people keep saying that you got to lower intensity when the rejection rate is too high. And I guess they might be right. Cause lowering my intensity actually results in fewer rejected shares. But apart from that - what's the reason for it? Shouldn't it be the other way round? Faster results = faster feedback to the pool = fewer rejections?!

I worked quite hard tweaking my setup, finding the perfect clock speeds, undervolts, bioses and bins for a rock solid, stable system - Now do I REALLY have to lower intensity/hashrate so that I don't end up with 10% wasted computes?
