I'm considering buying an X240, mostly because of the screen resolution.The X240 downside is the limitation to one memory stick, thus, 8GB. New sticks with 16GB are starting to appear in the market, but, it is unclear whether they are compatible with the X240
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?
I posted a similar message in another thinkpad forum, but, there has been no solution so far.

Do you think Lenovo and Intel would be working together towards the changes in the Memory Reference Code needed for accepting 16GB sticks? Is it for sure that those 16GB sticks will not work on the X240?
I'm having a hard time giving up on my X230 because of memory limitations. And I'm not enjoying the limited resolution of the screen I have either.
In my company, i see most people going for MACs, most under OSX, but also many running only Windows 7 with bootcamp. I'm a die hard PC user, but, I'm finding more and more attractive MAC hardware, with great screens and large memories.

While it is possible that Lenovo may support 16GB sticks in the future, right now the maximum supported is the 8GB stick. I'm sorry. I do understand that this may affect your purchasing decision.

@Myles_Lenovo: I could not find a way to send you a private message here. To whom could I send samples of 16GB modules within Lenovo and discuss technical details?

Since Lenovo does not currently support 16GB modules on the X240 there would be no one at Lenovo who would be able to discuss them. If Lenovo does implement support for 16GB modules, the specifications will be made available on the Lenovo web site.

Have there been any developments regarding 16GB memory in the X240? If a 16GB memory module is in fact available, is there a technical problem, or is it some other issue at play?
I understand that Lenovo's official position is that 16GB is not supported. My official position is that I'm not going to replace my X230 with anything less than 16GB. At this point the Dell 7240 looks rather attractive.

There have been no new developments at this time. There are a number of issues at play, including a need to find suppliers, test modules, and update the memory reference code in the BIOS to support the 16GB modules. I cannot say that 16GB modules will ever be supported in the X240, but it is possible support may be added at a later date.

I thought I never would see the day that I consider Dell, but, i'm now thinking the 7240 is an option.
After 5 months of using the X230, the speed is okay but the screen is pretty 2004-ish. And, I'm not changing the HDD on it for SSD, thinking on getting a new machine...
