Thnks Jeremy,

Anything specific of notable effect? 

I've read up on most of it I think. Top items;

Shut wireless networking off.
Dedicated irq to audio device.
Kill or disable power saving stuff
Minimize background proc intensive processes.

Realtimescan app reports all is well bar no RT kernel. Typical recording is at 44.1/16. 

Thnx
