FAQ about Lenovo Thinkpad E455 RAM
How much RAM can I put in my E455?
Maximum is 16GB total. You've got 2 slots, so that's 8GB per slot if you want to max it out.
What type of memory does the E455 use?
It takes DDR3 SODIMM modules - those are the smaller laptop memory sticks, not the full-size desktop ones.
What speed RAM should I get for the E455?
Go with 1600MHz (also labeled as PC3-12800). The system might accept other speeds but 1600MHz is what works best.
Can I mix different RAM sizes in the E455?
Technically yes, like 4GB + 8GB, but matching pairs (like 8GB + 8GB) usually gives better performance since it enables dual-channel mode.
Will any DDR3 laptop memory work?
Has to be DDR3 SODIMM specifically - not regular DDR3 desktop RAM. Also needs to be non-ECC unbuffered memory, which is what most consumer laptop RAM is anyway.
Can I upgrade to DDR4 instead?
Nope, DDR4 won't fit. The slots are physically different and the E455 only supports DDR3.
