Upgrading U5/10 270MHz to 333 - a wee problem

I've done this in the past but for some reason my aging befudled brain
is having a problem tihs time!

I'm trying to put a 333MHz cpu in a u5 which currently has a 270. The
333 works fine in another U5, but in this one it won't come up to
screen. The machine is fine with a 270 or 300, but won't run the 333.

Having read the manual I can't see a jumper to change the speed and I
don't recall needing to in the past. Any ideas?

TIA.

Turns out I need OBP 3.19 or higher.
