Its possible, that it maybe a Result of better A1200-Vampire Cooling using heatsinks,
  Cooling down unlocks x13?
  makes this possible?
  (Flypes CPU-Monitor shows this)
  Best Regards

  EDIT: i reopened the CPU-Monitor & its gone back to x12ůmy Question here, can the FPGA Modify the Multiplier, when its better cooled, & for some Moment Show what the Picture says, or was it a Register-read-Hickup?

I would say the on V2 FPGA the possible speed is between x11 ..x13
On the V4 FPGA the possible speed goes from x12 to x14.

Thank you for the Explainention

Its nice to know that the X-Multiplier can go between x11 to x14

But Its possible to get to x13 with a Vcontrol-Like Software-Switch?

Best Regards
