(what does IIRC mean?) I may be talking out my arse but I don't believe that different cores are limited to different cards, I've had GROGPU, GROGPU2, and TINKER cores and there's probably another one that I didn't even notice. Still 768pt WU's would be nice...
You can bet I've been refreshing and updating the WUD all the time, but it doesnt work.
UPDATE! So, with the -advmethods flag and the bigpackets=big setting, right now I'm working on a 472 pt WU. I'll let this one finish, and see if the next one is a 768/1888 WU. If not, I screwed
something up, but boy I'll still be mad if its a 472 or 511.
