I set up a new rig today, sapphire dual-x 7970's with cgminer on windows. I got it to 715k per card, but only around 10% of the work gets credited to the pool. The shares are not being submitted in cgminer either.The problem seems to be the intensity, I've tried a couple pools, and different settings. It's works fine at intensity 13 and starts going down with anything above that. This issue seems strange to me but I only switched to ltc recently. Anyone seen this before?
