on my 1g memory (or above) 5xxx and 6xxx cards ,the bitblockold algorithm works fine,but 512m cards can't run,says not enough memory.
I tried to decrease TC or increase LG,can't work neither.
seems that parameter "--thread-concurrency" and "--lookup-gap" don't play a part in Bitblockold algorithm.
Is there any other ways that can decrease the memory occupancy in order to let my 512m cards run the x15 algo？

Drop WS to 64 (or even 32 which I have not tried), gpu-threads 1. However I never got my 5450 to work on X15 ...

I've already tried,but it didn't take effect

Make sure to delete the .bin file before restarting sgminer or your changed config will not be recompiled ...
