P9700 processor on T400

[samurai123]

Currently my laptop has P8400 and thinking of upgrading to P9700. 

Does anyone have tried laptop monkey's processors available on ebay and known to be working?

I see they have listed aw80576P9700 with SLGQS and QLMA  version.  Does anyone know what's the difference and if these are compatible with T400?

Thanks in advance.

As far as I know, QLMA and SLGQS are the same. P9700 will use slightly less power and T9600 will give slightly better performance. Having said that, I believe upgrading the CPU is the least cost-effective way to upgrade a laptop. Faster disk and more memory gives you a greater return on investment.

I got the SLGQS version and it's working fine. Thanks.

One thing I noticed that the Device manager still shows the old ( P8400)  processor model. But the  Computer -> Properties show the correct processor model ( P9700 ).

Any idea?
