Sorry to report I switched the 6990 rig over to a LTC pool.
Reason : rejects all over the place.
The 7970 rig is still happy moooo-ing away however.
As I mentioned before, the 6990 on I 19 setting does not like the low diff coins.
The 7970's on I 13 dont care about it.
Same mobo/os/miner etc.
It has nothing to do with the pool.
Perhaps I'd better sell the 6990's and buy back 7970 instead....
Very interesting observations. Glad to hear its at least the more powerful card still happy!
