E330 (3354) CPU upgrade question

hello community,


well, i would like to upgrade CPU on my E330 (3354).

in stock setup, it runs i3-3120M CPU, BIOS version H3ET72WW (1.09).
i have a couple of options to purchase i5 CPU for upgrade, but i'm in doubt what exactly CPU will work.

i've looked at lists of replacement parts found on lenovo site, but those appear to be outdated, since they even do not list my CPU, only the similar i3-3110M.

so, my i5 options are:
i5-3210M (listed in lenovo docs along with i3-3310M)

does anybody know will these work?

Re: E330 (3354) CPU upgrade question

In principle, anything from the same generation that uses that socket should work.

AFAIK, there's no BIOS whitelist for CPUs. It is still recommended to replace it with one that doesn't exceed the TDP of your existing one to avoid heat issues.

W520: 2960XM, Q2000M @ 1091/1380, 32GB RAM, 500GB&750GB HDD & 500GB SSD, FHD&MB168B+
X61T: L7500, 4GB RAM, 500GB HDD, XGA screen, Ultrabase
W550s: 5600U, K620M at 1164/1281, 16GB RAM, 512GB SSD, 3K touchscreen
X200s: SL9400, 6GB RAM, 64GB SD card, WXGA+ screen
