Off topic just a bit, but figured you'd be interested. I don't have an account at Bitcointalk and no intention of ever getting one.
Your Neoscrypt kernel works fine on my HD7770 1GB, got it running one thread, 80khs, same TC and intensity as the Pitcairns and Tahitis. The 6870 1GB does not like it at all... I can only get that card up to intensity 14, 17khs. Anything above intensity 14 crashes the driver. Tried multiple TCs, one thread, different worksizes... no good for that card.
Everything else runs fine albeit with a ton of hardware errors, so I'm not going to worry about it. That card's turned off while the others play. I might switch back to 14.6 and putter around with it some more later.
Edit - got 'em all working, except one rig's fighting me over driver installation for some reason. Even the 6870 is working at 19khs. The MSI 280X is actually running slower than the Hynix 7950 for some reason (250 vs 275), so I still have some tweaking to do.
