When Cudaminer does this, attempting to mine afterwards results in a very very low hashrate (usually ~27KH/s on Scrypt). Is there anyway to resolve this without having to reboot the computer?

Any ideas?

Check you clock speeds after CudaMiner errors out. When I get errors out of CudaMiner, my GPU goes to "2D" clocks and gets locked there. Another way to get out of that mess is to launch Device Manager and then disable and re-enable the offending GPU.

Yeah I keep getting that cudaError 30 as well. Seems to be kind of random since I was able to mine for like 12hrs straight earlier. I was just trying 32bit miner on someone else's suggestion and it's definitely a bit faster, but the errors still happen. I haven't confirmed it yet but I seem to get them faster if my mem clocks are over +400, which is pretty weak on my evga ftw 750's. I've got to restart and play with my bios settings some more I guess. Not sure what else to try.
