^You aren't only one with Tonga.
It's true that this chip is inferior than Tahiti's, but man 160 hash/s is pretty low. Make it at least 220-230 h/s.
It looks like there's at least 4 of us with Tonga chipsets who have replied to this thread. Claymore can you please see about making some improvements for this chipset? Sending a little love towards the "budget" miners using Tonga cards would be much appreciated. These cards really are capable of a lot more speed. Thanks again for all the hard work you do for the community!
I wish folks would talk about card models, not chipset names - some of us do NOT have the HUGE number of chipset names memorised.
