How to overclock the processor in HP Microserver?

Question

HP

Interested in this question. Has anyone overclocked the processor in the HP Microserver N36L?
The question arose from this. As everyone knows, the G7 line has dual-core Athlones. The younger model uses a processor with a core frequency of 1300 MHz, in the N40L 1500 MHz, in the older N56 2200 MHz.
So in my younger model, the DMIDECODE command writes the following about the processor:

capable the maximum frequency is just the same as that of the older model. This suggests that the stones are the same everywhere. Moreover, it is known that apart from the processor, supposedly, these models are no different.
The question arises: has no one yet tried to make an older model from a younger model? And if not, where to dig? There are no such settings in the BIOS.
