Hi, I have in mind an upgrade for my good old friend (Lenovo Thinkpad T440p), i want to replace my i5 4300m with a i7 4800MQ, please let me know if it is possible and what power brick i need. PS: My motherboard socket is 947 rPGA and the i7 needs 946 rPGA PS number 2: I saw t440p's with i7 4800MQ with the identical motherboard.

Re: T440P Upgrade

Welcome to the forum!

 

That should be no problem, this mod has been reportedly done by many forum members. Is plug&play.

 

You will need to have a good thermal paste though, and clean the old one from the heastink.

Re: T440P Upgrade

They use the same socket.  It will work.  You don't say whether you have integrated or discrete graphics.  I would use one size larger adapter than the original.  For example, if you have 65-watts, I would use 90-watts.  If you have 90-watts, I would suggest 135.  The 135-watt units are much larger.  I might also try to check current usage if you can get your hands on a current meter.  A 90-watt MIGHT work, but you don't want the adapter to overheat or have the laptop need more than the adapter can supply.  In real terms, the quad-core cpu uses 12-watts more than the dual-core one

If your adapter is 65-watts, I would use 90 watts.  If your adapter is 45-watts, I would use 65.

That sould work, altough with such a maxed-out machine, you probably will not notice a jump im performance with a quad. Unless you use sofware like CAD or applications that really profit from 4 cores.

 

From memory, there is no better fan than the one you have. To improve cooling you will need to have a very good thermal compound, like Thermal Grizzly Kryonaut. And make sure you use a 90W PSU
