M4400 Upgrade to Intel P9700 CPU

I just wanted to let everyone know that it works and doesn't require an OS re-install like the Yonah-Merom upgrade did on my Toshiba.

The P9700 is ideal because it consumes 28 watts, but operates at 2.8 GHz and has 6 MB of L2 Cache. The T series, which tops off with the T9900 is only marginally faster and consumes 35 watts. The rest of the P series consumes 25 watts.

Consequently, I found the P9700 to be the best performance/power usage ratio for this laptop/platform. Currently it is only available through OEMs as a configuration option on a few Sony Vaio laptops.

If anyone is interested in a P8600, check eBay in the next week.

Does anyone know when the Core i7-based Latitude/Precisions will be coming out?

 

Hey Nightalon,

Thanks for the useful info.
I have a question:
I have an Intel P8600 (Thinkpad x200) and would like to downgrade the CPU to a CPU with lower consumption.
Do you think I can fit an Intel SL9600 or SU9600 into the X200?
Cause it seems like the SL and SU series have a smaller form factor than the P series.

Thanks,

Alberto

 

Alberto,
you should ask that in the Lenovo forum, since that's a lenovo question. I'm not sure, because the X200 CPU may be soldiered to the motherboard. I also think that you're right about the form factors, so I don't think it is possible. But, you can always ask the question in the Lenovo area.
