I suspect this is true.  I bought a 540 and was surprised that it didn't
run a particular program at quite the speed that Les Currell was claiming
for his home-made Arm 3 upgrade.  I suspect the 540's as sold aren't
running at maximum speed; I haven't got the dhrystone code out yet to
check and I haven't been bothered by it enough to open it up and look
at the crystal.  If anyone really wants me to I will.  If it turns out
that the machine is rated at less than the speed claimed in the advert
I looked at just before I bought it, I wonder what I should do? ;-)

[relax Acorn - it's fast enough for me :)]
