im just look on my rb 1000 and see frequency 1500mhz, so try put 1000 and receive massege "no supported change frequency" only 1500 .... im try older version mikrotik 6.20 6.10 5.20 5.10 5 and the same situation so firmware is 2.30 always ..... please give advice how to set 1000!!!!!!!!!!!

If you can, use one serial cable to reset bios (the only point where cpu speed are stored) after reset, chose inside the bios (on serial port) the wanted speed.

The 1000 must run at 1333MHz with default 512MB on board.
