FR645m uses natively 1kB more than FR645?

While adding support for the FR645 and FR645m in one of my datafields*, I see that the FR645m crashes. It uses 0,1kB more than the FR645 with exactly the same code...
I was hoping for CIQ 3 with more storage instead of still using CIQ 2 with less storage :mad:
