I made 13.812 sec. at 3.6 GHz CPU and DDR3 platform (DDR3-1864 6-5-5-12).

For me it is really hard to think about a tweak able to make a gain of 0.344 sec. in superPI 1M with DDR2-1233 5-5-4-10. It is really a big challenge, I can not figure out how this is possible.

But before to give my final opinion a I have to try if this works for me. It would be really great!
I do not know if I will be able to reach 13.468 sec. but for sure if the tweak works I would make better of my best 13.812 seconds.
