Look into learning to set Affinity on Pifast. You should definitely be able to run this at the same frequency as your 32M run (usually 100-200MHz higher). The fact that it's running at a much lower frequency indicated it ran on a weaker core!

(or you ran this before tweaking and reaching the higher frequencies)

107.0 x 63 is a round'ish frequency, he was prolly just scatter benching.

If you run before getting more,

PiFast did before, then went up higher,

There are some PiFast theaks for?
