The more threads you have the greater amount of ram you want to manage this otherwise you lose allot of the power of the Dual Xeon. This does not just have an effect in AE because you assign ram per thread. You just have more control there because of that.

I have 64GB of RAM and that still doesn't make a difference to multithreadedness in certain CODECs. Would this mean I need 128GB?

If you turn the Core Parking off in the registry then that will stop the OS control on this.

This is not the reason Premiere doesn't use all CPU cores when rendering. It is CODEC dependent. H.264 is bad at multithreading while MPEG2 is good. My 3D software is great at using 100% CPU. All these results are with Core Parking on.
