I read any topic, where HD2 was overclocked to 1,5GHz, but i can't do it. Can you anyone help me?

Thanks

It has been a long time since this topic so my memory may well be faulty or not so accurate.. :-[ As I recall, Qualcomm never released any info about pll limits, multiplier limits, oscillator limit or internal clock logic (hardware) for rounding of clocks and keeping them in limit.
The so called faster speeds of the HD2 overclock, as I understand it, is not an actual overclock - that is,
it is actually 1198 (1602 but with 1350mv). The CPU can't work faster. If we set higher clock to frequencies the CPU will stall.
So, it is not really 1.6Mhz, just more scaling and more voltage than was the 1198 by default.
You can refer to the avs.c in arch/arm/mach-msm/ and acpu-scorpion.c (the name may be slightly different)
