Processor Upgrade for T520

Hello,

 

I have a T520 Thinkpad with an i5-2520M processor and would like to install an i7. The i5 is the 8th gen dual core and hopefully I can speed this laptop up with the i7. My understanding is that you cannot replace a dual core with a quad core. Is this correct? If not then I'd shoot for something like the i7-6700HQ or some similar low cost i7. This should take a g2 socket if I'm not mistaken. Does anyone have a recommendation?

Re: Processor Upgrade for T520

You can install an i7 but it must be a Sandy Bridge CPU (i7-2XXXM) to work with the chipset.  You should use one that was supported initially by the BIOS: (i7-2620M,  i7-2630QM,  i7-2670QM,  i7-2720QM,  i7-2760QM,  i7-2820QM,  i7-2860QM,  i7-2920XM or   i7-2960QM)

 

Note that the last 2 processors are 55W TDP (thermal design power) and they were only sold on W520 models.  They normally take a different (larger) fan and the W520 fan will not mount correctly on your machine.  If you try to use those CPUs on your T520 you may overheat.  I don't know if the power circuitry on the T520 is the same as the W520 so there may be other problems.

Re: Processor Upgrade for T520

@richk The last CPU should be i7-2960XM, isn´t it?

I did not find "i7-2960QM" in Pass.Mark
