Lenovo B590 Model 6274 update with a compatible CPU?


I would like to upgrade my Lenovo B590 Model 6274 (Intel Core i3-3110M 2.4 Ghz, 4 Gb of RAM...). by adding another 4 Gb of RAM and upgrading the CPU.

I looked on the forum about similar posts, that redirects me to the page 85 of the hardware maintenance manual:



At this point, I thought about getting a second hand Intel i5-3210M 2.5 Ghz.

But I find this post that simply mentions that the i5-3210M is not supported:

If the machine comes with a Intel HM76 Express chipset, you should be able to put an Intel I5-3230M 2.6Ghz (the i5-3210m 2.5Ghz is not supported)

How can I be sur this CPU is compatible with the computer?

Thank you

Hi Dadioa,


Welcome to the Community Forums.


As shown from the hardware manual , i5-3210M is the highest CPU offered for the B590.

This is not only compatible but was also released with the  i5-3210M as marketed here.


The mentioned post was relating to probable upgrade from Celeron to icore series on a G500 in relation to the chipset compatibility only. 



Intel HM76 chipset supports i5-3210m as shown here (to choose compatible products).

CPU upgrade checker here shows Intel Core i3-3110M (PGA) CPU has 91% upgrade chance for Intel i5-3210M.


Finally using the same Machine Type: 6274 here on the parts lookup page offers part number 102500301 Intel I5-3210M 2.5G L1 3M 2cPGA CPU.

Personally to be 100% sure of any upgrades we do, I take the chance to test it with a spare if available.
In any purchase, verify the return options specially when getting parts from third party resellers.

Hope this helps answer your query.
