From dmesg:

A6 - Debian bone 60 - vdd-mpu 1100 mV, Bogomips 545
B - Debian bone 60 - vdd-mpu 1100 mV, Bogomips 545
C - Debian bone 60 - vdd-mpu 1325 mV, Bogomips 993

Also:

A6 - Angstrom 3.8.13 - vdd-mpu 1100 mV, Bogomips 545
B - Angstrom 3.8.13 - vdd-mpu 1100 mV, Bogomips 545
C - Debian bone47 - vdd-mpu 1325 mV, Bogomips 993

Do this mean that the A6 & B boards are running at 500 or 600 MHz?

With the little information you have shown.

My guess, your Revision C is running a newer bootloader that enabled
1Ghz at bootup..

What information would you like?

What is the latest version of the bootloader for these boards?

Well, since the "C" works..

Run the debian flasher on the A6/B

Ok, will do that tomorrow and report

This board is an A5A off the first production run I think. It came from Digi-key ? Not sure my buddy pre-ordered one for himself, and one for me ~2 months prior to release. Not sure init daemon matters, but there it is.

By the way. For what it is worth. While the CPU profile is set to ondemand, the processor will stay at 300MHz until CPU utilization goes above 60%. I tested this early on last year with a simple load test application that I wrote. Which I think I may have even posted the code on these groups . . . I dont remember.
