T450 and T450s memory slots

Does the T450 and T450s have space for one or two memory modules? One soldered and one slot? If they have one soldered and one slot, is it possible to order with 8GB soldered (and no module in the slot)?

Re: T450 and T450s memory slots

Hi, tesorn, and welcome

T450:
16GB max / PC3-12800 1600MHz DDR3L, non-parity, dual-channel capable, two 204-pin SO-DIMM sockets

T450s
20GB max7 / PC3-12800 1600MHz DDR3L, non-parity, dual-channel capable, 4GB memory soldered to systemboard, one 204-pin SO-DIMM socket

It's possible to purchase T450s with 4 GB RAM soldered and empty slot.

Re: T450 and T450s memory slots

The 8GB option for the T450, is that 2x4 or 1x8 soldered? Btw,  the optical is ultrabay?

Re: T450 and T450s memory slots

Where do you see soldered RAM mention in the T450 specification quote above?

Usually 8 GB RAM in the dual slot models with maximum 16 GB or 32 GB means the single RAM stick installed.

Models above don't have built-in optical drives or a bay for such drive.
For more details about their specifications read PSREF:

Re: T450 and T450s memory slots

The T450 has 2 memory slots; the T450s has a single slot with 4GB soldered.   In general, 5th generation machines will support the 16GB DIMMs now available.  They are expensive, but they do allow more expansion. This implies a max of 20GB on T450s and 32GB on T450.

Re: T450 and T450s memory slots

asoufi,

indeed, shop.lenovo and PSREF site mention 12 GB only value:
http://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20T450s/ThinkPad_T450s_Platform_Specificat...

But:
1. PSREF pdf file includes specification with RAM maximum 20 GB. For example the last edition with T450s listed in (laptop has been withdrawn in July 2016):
http://www.lenovo.com/psref/pdf/psref491.pdf

Even older editions mentioned maximum 20 GB

2. Actual T450s fru bom file lists 16 GB module:
https://us.download.lenovo.com/parts/ThinkPad/t450s_frubom_20160115.pdf

3. Actual on-line parts DB lists 16 GB module for T450s.

So, no dubt T450s supports 4+16 GB of RAM.

Re: T450 and T450s memory slots

I have a T450s with 4+4GB of RAM. I have several operations that could use more RAM so I'm considering upgrading to 4+8 or 4+16 but I understand I'll lose 2 channel mode. What is more valuable? More memory or dual channel?

More memory, especially if you "have several operations that could use more RAM."

 

Dual channel slightly improves performance compared to single channel. More memory dramatically improves performance of RAM-starved applications.
