For reference, on my 48GX SN 3443S in the interactive self-test (ON-D) test [A] returns a speed of ~3.93 MHz. (Exit of the self-test is done by ON-C)

Funny enough I was reading somewhere the other day(that seemed fairly reliable) that when the 48G series came out that they were having 4MHz yield problems -> binning. The Xs got the 4MHz "good" chips and the other got the not quite able to make 4MHz chips... (c. 3.5-7MHz IIRC)
