is proj 18432 single or double precision?

[Knish]

I tried overclocking a 750ti that's been folding great as stock for over a year. I know FAHBench is outdated, but tests with double precision seemed ok yet single precision would fail even with no overclock. After a few good units were completed with the overclock, I just got a crash with 18432 so was just curious if single/double has any relevance? (the same WU started after reboot, so in about 3 hrs I'll hit the same point again without overclock this time so I still get to turn this wu in)

The vast majority of floating point math in F@H is single precision, as I understand it some of the checkpoint math is double precision.

Double precision performance is always limited by vendor, so it doesn't push the GPU very hard. It's not a good way to check stability.

All current FAH projects use mixed precision : the majority of computation is done in single precision and some specific operations are done using double precision.
