Tried out spitweaker. I am a n00b and it added 6 seconds to my pi time.
My old faithful trick on 1M seems to work with 32M although the second trick does not .
I run 16k twice before running 1M. Than I run 1M again. makes a nice difference.
2x16k before 32M seems to make a difference of a few seconds on 32M (for me dropped me from 18m 37s to 18m 31s) as well. running back to back 32M though was slower. Tired of running it right now LOL I think 6 hours of Pi is enough for one night. Asus board is crap, 2350ish is my max NB speed. Again my cheaper crappy foxconn board does better WITHOUT having CPUNB controls *sigh Time to upgrade.
Happy enough though. My first 32m time was almost a full minute slower than my current best on the same hardware

I nice ~8% improvement overall
EDIT: Oh maxmem and system cache mode definitely helped
