Does anyone know the maximum ram supported on GS45 intel chipset used in Lenovo X200 Tablet

The user manual suggests it's 4gb, is it worth taking the risk and upgrading to 8gb.
Reason for upgrade: Faster machine since I also plan buy an SSD to go with it

take a peek on Crucials website - http://www.crucial.com/uk and that will tell you what you need and what it will support.

Even though the chipset manufacturer claims 8gb, the laptop manufacturer has to include that in it's build and BIOS.  Crucial work with all the mainstream laptop makers - they would know.

Hi Netpro, if you follow the following link (page 3 is the spec page), Lenovo says that your x200 will support up to 4GB of 1066MHz DDR3 SODIMM (2GB per slot) providing you're running a 64bit OS (32bit can address 3GB according to the Lenovo spec sheet).

Hope this helps?

Dear dlancelot,

I think I may have found the solution this question, please read foot notes on the same pdf BUT on PAGE 4 , they read as below:-

Footnotes: [1] Memory: Lenovo notebooks have a new 64-bit architecture. Notebooks with a Windows Vista 32-bit or previous Windows 32-bit operating system can support up to 2.5GB of addressable memory. Notebooks with a
Windows Vista 64-bit operating system can support up to 8GB of addressable memory.


Do youthink it is possible now to support upto 8gb on Windows 7 64bit professional since its kind of equivilant to vista 64 bit business?

In that case, order a couple of 4GB dimms from Crucial.  If they don't work, send them back.

Netpro, it also says in the footnotes "Maximum capacity may require the purchase of optional component".  If you need 8GB of RAM (doing photoshop, etc.), then I would recommend going to a local tech shop and having them install 8GB and see if the BIOS recognizes it (or purchase RAM at a local vendor that has a 100% money back policy and do it yourself if you're comfortable doing it).  Otherwise, farting around with the Lenovo tech support is going to be more of a headache than it's worth imo as they probably don't even know!  

This may also require a BIOS update to support the additional RAM, if you feel comfortable doing this, then here's the link for your update (update is dated 2010, please choose the correct OS that you're currently running to perform the update, if you're not comfortable doing this, please have the tech shop do it, as if it's done incorrectly, it will possibly "brick" your tablet):
