Hi again
The 10k resistor does maintain the access rights within the clock generator chip. If tied to VDD then the chip won't allow overwriting its internal clock registers. If tied to GND the clock frequency can bed adjusted with software tools as SetFSB etc.
Please be aware that the resistor is
really tiny (0402 form factor) and it requires a certain degree of experience with handling of microelectronics. You need a supersmall solder tip and some very thin solder wire. Otherwise the mission will fail...
I also experienced that shifting the gears down from high clock frequencies will lead sometimes to a system crash if both FSB and PCI clock was modified. This can be prevented by adjusting only the FSB what is adequate for all the relevant applications.
Today I performed a Passmark 7 benchmark on the second machine with impressive result:
I also tested the 1080p capability. With a little more throttle (approx. 1.9 GHz) the 1080p footage is played with no stuttering at all!
Enjoy!
