Lenovo ThinkPad X240 - 12.5' - Core i5 4300U - 4 GB RAM - 128 GB SSD overview and full product specs on CNET.
Video showing how to take apart the Lenovo Thinkpad x240 to upgrade (remove and install) the RAM from 4gb to 8gb. A note about the installation:The x240 does. I learnt that X240 has 2 slots for M.2 SSD. One is occupied by a 16GB SSD cache drive (this is what I find in my device manager) and the other is for WIFI card. I wanna replace the 16G SSD with a new SSD as windows drive, keep the HDD and upgrade to 8GB ram as 16GB is not supported.
Hi guys,I got a few questions regarding upgrade of my X240. I learnt that X240 has 2 slots for M.2 SSD. One is occupied by a 16GB SSD cache drive (this is what I find in my device manager) and the other is for WIFI card. I wanna replace the 16G SSD with a new SSD as windows drive, keep the HDD and upgrade to 8GB ram as 16GB is not supported.
My questions are:
1. Is it any 2242 m.2 SSD with be OK? Which model is crecommended? 128GB or 256GB?
2. Some said the slot is for cache drive only. Is it really OK use it for windows drive?Hi all,
I'm considering buying an X240, mostly because of the screen resolution. One downside of the X240, is that it only accepts 1 single SODIMM, which to now were only available up to 8GB sizes. I do need more than that to process the datasets I use.
Has anybody tested these? Does the BIOS allow for 16GB?

They appear to have a module code IMM2G64D3(L)SOD8AG which appears to be the first 16GB, and can do DDR3-1600. They may become available by mid April at $300
This post suggests it won't work...

On the other hand, it was 'undocumented' that 2 8GB sticks could be used in X2xx series back in the day..
Adding a bit more info
A person from intelligentmemory says that a Haswell machine will not work with these chips, unless a change of the memory reference code, which is part of the BIOS. It is not yet 100% sure if it can be fixed by a BIOS update or not. On March 10, 2014, they did have a customer make it work on an Ivybridge E by modifying the memory reference code. Lenovo could work with Intel, and change this code.
