[Closed] laying chipboard floor - t&g joins don't align with joists - solution?

as above really. I'll be laying a new chipboard floor over some old joists, some of which have been replaced and now it is all insulated.
The joists are not 2.4m spaced to line up with the join on the short ends. How do i resolve this?
I guess I can always cut the boards and line them up on a joist and screw down without a t&g joint.
or maybe I put a load of noggins in where the joins are to support - but these will then be 90 degrees to the join and will be a right pain now the insulation is in between the joists!
