Core i7 2820QM

[crazysteve240]

Will a Core i7 2820QM be able to replace a Core i3 2310M on a Lenovo Thinkpad E520? I checked CPUBOSS and they don't have a socket type that matches, but a Core i7 2620M also doesn't have a socket type that matches (when it's supposed to according to the Lenovo website).

I wouldn't count on it. The laptop motherboard probably won't support it, the socket is different and the i7 needs more power as well.

Based on this thread a user did successfully upgrade his E520 to an i7-2820QM.

It really depends. The 2820qm comes in the PGA988 package which is a removeable socket. The 2310m can be either pga988 OR bga1023 which is soldered.

 

You will need to figure out which format your laptop has first, and then research whether or not the laptop BIOS will recognize the 2820qm.

Indeed, I have an HP Probook 4540s that was supposed to be a PGA socket but it turned out that the one model I bought was the only one to have the BGA socket so I wasn't able to upgrade it.

Just disassemble the laptop and you'll be able to tell which socket it is right away versus trying to fish around for the information online with your serial number. If it's a PGA socket it'll have the retention screw that locks it into place at the top of the socket, if it's a BGA socket then it'll be a lot smaller than a PGA socket and won't have the retention screw. Just make sure you have some thermal paste before you disassemble it if it's your only computer otherwise you won't be able to reassemble it

Why is that?

Well, it won't physically prevent you from reassembling it the machine, but the CPU will overheat if you don't apply thermal paste before putting the heatsink on.

You'll need to clean the old thermal paste off the CPU and heatsink and reapply new paste. The reason is because when you separate the heatsink from the CPU it will create air bubbles in it when you reattach the heatsink which will really hinder its heat transfer ability.

 

Plus the old paste will most likely be pretty dry and brittle since we're talking about Sandy Bridge era CPUs here.
