I been reading here and over the net but i cannot find anything.

Unfortunately I don't have 600X.

I spent over an hour looking for the part on the motherboard. At first I thought that maybe a different part was being used so I entered at least a dozen part numbers into the alldatasheet.com site but didn't find anything that could be a clock generator. Then I noticed a couple of insulating sheets of plastic around the MiniPCI area. I peeled back one piece and there it was:
Picture of 600X showing IMI C9714 (158KB)
This view is of the bottom side of the motherboard with the I/O ports at the top and the memory slot at the bottom.
Finding the datasheet is the good news. The bad news is that looking at the pin descriptions it appears to be a little bit different than the PCK2000(M?) device. Pin 16 is the selection between 66Mhz and 100Mhz. The adjacent pin (#15) is marked as VSS, which is ground. It may be that it is an actual ground pin OR it might be like the PCK2000 device where it is a select pin that in normal operation must be grounded. I suppose the only way to find out is to cut/lift pin 15 and connect a pull-up resistor (say 5K-20K; just a guess) to pin 19 (VDD).
Note: I cannot guarantee that this will work as an overclocking solution. Nor can I guarantee that damage will not occur to your motherboard.
From looking at the PCK2000M datasheet, the SEL pin (16) should normally be tied to power. Since the 8% FSB mod is supposed to be done by attaching a 1K resistor near the CPU module connector (which is on the opposite side of the 600X board where the IMI C9714 chip is), I would imagine that what is really happening in the 600E is that the PCK2000M SEL pin is being grounded. That would place the device in "test mode", according to the PCK2000M datasheet. No such mode is evident from looking at the C9714 datasheet.
In short, I cannot say for sure that it is possible to overclock the 600X motherboard in a similar manner (adding a resistor) as the 600E.
