Success in overclocking TP240 (type 2609-21G) (with PICS)

This was the next MOD to my ThinkPad 240:
I've successfully raised the FSB from 66 to 100 by playing a little with PLL (it is located under the CPU - on the other side of the motherboard).
I haven't taken any pictures before the mod, but I haven't done much. I have only de-soldered the resistor pack and made the connection marked in red.
After turning it on the processor ran at 450MHz but making it faster made it become hotter. The system became unstable. After some search on the INTERNET I found a person's blog who was trying to do the same. He later tried to decrease the multiplier - i've done that to. I've de-soldered the 100k resistor marked red and shorted the pads marked cyan.
By decreasing the multiplier i've also decreased the processor speed 50MHz. It now seems to run stable at 400MHz, but still quite hot.
