Reward:Well, whatever the dumb thing I did after BIOS flash could happen to anyone. Resetting the BIOS in a laptop is not a fun task unless it is one of those weird things that you enjoy; like me.
Changing the CPU was just a coincidence when I came across the T2300 while waiting to board a plane on my way to Thanksgiving break at the airport terminal.
Let's see how much performance gain from a mere 60mhz increase in speed, 1MB more cache and the change of 533 to 667 FSB.
About 11% gain from 3D01 and 5% from 3D03
SuperPI 1M is ~17.6% faster and 2M is ~6.8%Yet, the T2300E is Prime stable at only 0.95V using Notebook Hardware Control.
At this point in time I can safely assume all 533/667 FSB would work but not the 800 FSB mobile CPU. The reward is not much switching from 1.6Ghz 533FSB 1MB cache to 1.66Ghz 667FSB 2MB cache. It is good too know when the price of used 667FSB Yonah and Merom comes down, maybe I should look for T2600 or T7600 next time; I don't pay a lot for CPUs. Until then, have a safe holiday season.
