First, define "acceptable". Microchip guarantee that a PIC can be
run at its maximum rated frequency with no adverse effects on its
performance

If it doesn't, that's their problem. If you flout the specs and it acts
oddly, the problem is yours

As you might realise, 40MIPS is probably not attainable in PIC
s/w at 40MHz. The dsPIC FRM says "up to" 40MIPS. 20MIPS
is "up to"
