"At this time".
BTW, where did you come up with the 952607 info?
I first tried clockgenhttp://www.cpuid.com/clockgen.php
then tried cpufsb from this thread.
from clockgen site, 952618 seems like a better fit, and using it with cpufsb, I was able to get something like 533MHz to show up in system tray during lockup (tested 133/33). At least it did something.
As to overclocking in general, go for it!
Most CPU's are all made the same, and clock speed adjusted later.
So the only difference between a 2GHz and a 1.8GHz may simply be the label stamped on it (as well as a jumper intact or cut). There is also a margin of error built in to electronics that can easily be 20% or higher, so overclocking a 2GHz CPU to 2.4GHz would not be a stretch at all. I spent $100 extra to get a 1.8GHz, and never would have spent $300 to get the 2GHz version. Overclocking is money in your pocket! As long as you monitor CPU and system temps, and run stress tests after every small overclock increment, you will not harm your CPU. Sure, you will lower it's lifespan, but it will be very outdated before it's life ends from overclocking.
