From the Whatsnew file at Prime95:

3) Some of the new, faster FFTs don't let us do as much error checking on each iteration.
If you don't want to lose this error checking, choose "SUM(INPUTS) error checking" from
the Options menu. This will slow down your tests by about 2-5%.

Maybe try that and see if the errors go away...

Otherwise, try defaults for speeds, disable OC, and try again. Usually those errors happen when you get an OC induced error.
