I am assuming that you were doing a single WU using all 8 cores. 5800X has a 32MB L3 cache. a 3200K FFT takes 3200*1024*8 bytes or 25MB. That will fit within the 32MB L3. Clearly the 6M FFT,...

There is virtually no cost in throwing in a 'p' in the B1 product. If it helps in finding an odd P-1 factor here or there, that is always a win.
