I've also received a report by email that some 750 TIs just drop their hash rate randomly, but sometimes they recover. It's spooky.

I am hashing on Jackpot right now with the -q flag off to just watch the numbers for a bit... will let you know if I see anything like that.
Is ~3 Mhash/s for each 750 ti about right after the switch?
And with the cards dropping speed, has anyone tried it without the -d option? I am not using it since all 6 cards are on the same instance right now, but thought we should be thorough in testing.
