Hi all,

A number of slots (Wi-Fi, M.2), the drive bay, the fan system and one memory bank can be found below this maintenance hatch. Unfortunately, this is indeed the only RAM slot on board, being occupied. 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. The X240 long battery life laptop is the thinnest and lightest ThinkPad laptop we offer. Weighing in at less than 3 lbs and measuring 0.8 inches at its thickest point, the X240 is ultraportable — without sacrificing anything in terms of laptop battery life, ports, connectivity, or durability.

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.
Any ideas? Any Lenovo and/or Intel folks around?

Lenovo X240 Memory Upgrade

sancatHi 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:
