Speed grade C4 micro

My question has to do with the speed grade of the OMAP 3430 used on
the C4 (original) Beagleboards.
Are they 600 or 800Mhz parts?
Also if all the C4's were shipped with the same speed grade?

It's a OMAP3530, not 3430

Are they 600 or 800Mhz parts?

720MHz parts actually

Also if all the C4's were shipped with the same speed grade?

AFAICT, yes.

Yes.
