Re: T440 upgrade RAM

Hello there!

Let me start saying that I am quite ignorant when it's about computers, so please try to be as clear as possible :)

I have a T440 i5-4300, 4GB RAM. I'd like to upgrade my RAM because sometimes when I work on my music, the machine is quite slow.

Therefore my questions are:

- How much RAM can my computer have maximum?

- How many slots does it have? And therefore shall I install my new RAM next to my old one or completely replace my old one?

- Could you please tell me EXACTLY what RAM models are compatible with my machine? So..what should I buy?

I really really REALLY appreciate your help.

Thanks,

Tiz

Re: T440 upgrade RAM

Your PC takes this spec for RAM:

PC3-12800 DDR3L DRAM 1600MHz SODIMM

The "L" means "low voltage", 1.35volts.

The device has 4GB soldered on the board. You can add 8 GB more in a single module. Read your User Guide or Hardware Maintenance Manual for how to do it. Search support for those docs.

That spec is an industry standard, so any of the major players will have it. You might check out the Crucial Memory Finder to confirm that for yourself.

Re: T440 upgrade RAM

The maximum RAM is 8GB. There is only one slot. You need 204-pin DDR3L-12800. (The "L" means low-voltage or 1.35V) Avoid modules that say "value", like Kingston Value RAM or Corsair Value Select. Everybody has his or her favorite brands. You can always buy it from Lenovo if you want to be sure of compatibility

There is NO RAM soldered to the board. (only on T440s) The maximum RAM is 8GB. There is only one slot. You need 204-pin DDR3L-12800. (The "L" means low-voltage or 1.35V) Avoid modules that say "value", like Kingston Value RAM or Corsair Value Select. Everybody has his or her favorite brands.

Re: T440 upgrade RAM

There is a bit misunderstanding above. So, the quote from the PSREF, T440 specification:

"8GB or 12GB* max / PC3-12800 1600MHz DDR3L, non-parity,
dual-channel capable*, 4GB memory soldered to systemboard on selected models, one 204-pin SO-DIMM socket
(*for the models with 4GB on-board memory)"

Examples of models:
20B6006AUS, 0+4 GB (i.e.no RAM soldered + 4 GB DIMM)
20B6008FUS, 4+0 GB (4 GB soldered, no DIMM)
20B6009MUS, 4+4 GB (4 GB soldered, 4 GB DIMM)
20B6005CUS, 0+8 GB

So, tizzopil, to answer your question provide, please laptop MTM.

Re: T440 upgrade RAM

Laptop has 4GB memory soldered to the systemboard:

SYSTEM BOARD FRU 00HM165 - W8P,i5-4300,UMA,4G,AMT,TPM,VPRO

So, the DIMM slot is empty, maximum RAM is 4+8 GB

" I don't know what to do with this information though haha"

"So, the DIMM slot is empty, maximum RAM is 4+8 GB"

Tiz, that all means that you can add up to 8GB RAM of the spec that was quoted above. Buy a single module, not 2x4, which often come as a kit.
