Hi all,

Product Features Manufacturer/Model: Lenovo ThinkPad X240 Processor: Intel i5 Dual Core Gen 4 2.10 GHz Memory Installed: 8GB DDR3 Maximum Memory: 16GB Memory Slots: 2 Slots Hard Drive: 320 Optical Drive: Not Installed Video Card: Integrated/On-Board Graphics Screen Size: 12.5' Battery Life: Battery is the original battery and tested to hold a. The CPU does not support more than 8GB of RAM per SODIMM module. In particular, Linux and Windows fails to boot, and MemTest86+ crashes, when using a 16GB SO-DIMM module, model IMM2G64D3LSOD8AG-B15E from Intelligent Memory (which does work in a ThinkPad X250).

  • Lenovo ThinkPad X240 is a Windows 7 laptop with a 13.30-inch display that has a resolution of 1366x768 pixels. It is powered by a Core i7 processor and it comes with 8GB of RAM.
  • Lenovo only tested 128GB when they released this machine, but you can absolutely use larger edition, I believe at least 512GB would be good. Do not try to use SDXC card as a major source of your storage as your data may be dangerous bc SDXC is far.
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. Thinkpad
Has anybody tested these? Does the BIOS allow for 16GB?
Memoryhttp://www.intelligentmemory.com/dram-m ... 3-so-dimm/
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

Thinkpad X240 Memory Slots 1tb


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?
