Thinkpad X260 won't boot after RAM upgrade

Hello, all.

 

I am trying to upgrade my Thinkpad X260 to a 16GB stick of ram. The exact item I bought is called "Crucial 16GB Single DDR4 2133 MT/s (PC4-17000) DR x8 SODIMM 260-Pin Memory - CT16G4SFD8213" on Amazon.com .

 

After installing the memory module (correctly, using the video Lenovo provides on youtube), the laptop won't boot. I can't even get into the bios, although the green bower button lights up.

 

I'm very confused as I did a lot of research to make sure this ram is supported by my thinkpad:

 

The Thinkpad platform specifications list the memory as "2133MHz DDR4" with a 16GB max

The voltage on my ram is 1.2V, the same voltage that the thinkpad x260 supports

It's also "260-pin memory", the same as the original ram.

 

What could possibly be going on? Why won't my laptop boot with the RAM upgrade?

The Crucial compatibility list for the X260 can be found Here...

 

It shows that a "Crucial 16GB DDR4-2400 SODIMM - CT8112843" as the recommeneded product for the X260.

 

You have a DDR4-2133 DIMM so that may be the problem.

Re: Thinkpad X260 won't boot after RAM upgrade

Hi billbolton! Thanks for the reply.

Unfortunately, your link doesn't work for me.  Of course they recommend the 2400MHz RAM, because it's more expensive, but the thinkpad comes with 2133MHz ram by default and supports that speed.

 

The memory is DDR4-2133 SODIMM (or SO-DIMM), which is the exact same as the RAM that comes in my thinkpad.

 

It's 2133MHz, DDR4, SO-DIMM, same voltage, same type of memory, not too big, etc.

As far as I can tell, it should work. Here's the actual Amazon link:

Download CPUZ from here:

Post a screenshot of the SPD tab, showing OEM memory specs.

Also take a picture of the New memory stick label.

Re: Thinkpad X260 won't boot after RAM upgrade

Your Amazon supplied RAM may be faulty, or there may be some incompatibility between Crucial 2133 RAM and the X260.

 

The prima facie situation is that Lenovo specs 2133 but can only guarantee that the RAM Lenovo supplies will function, for obvious reasons. I am not seeing anything at all in term of reports with the X260 showing any  general incompatibility with third party RAM products

 

If you buy a third party RAM product there is always a risk on incompatibility in the RAM product.

 

Crucial indicates you should use a 2400 RAM product, so perhaps they are aware of a compatibility issue with their 2133 RAM product.  

 

In in any case, Amazon states the 2133 product is compatible with an X260, so you should be able to return it to Amazon on the basis of not being fit for your purpose, despite their stating it should be.

Re: Thinkpad X260 won't boot after RAM upgrade

I visited Crucial's website and used their Crucial Advisor tool for Lenovo Thinkpad x260 RAM and the only two 16GB modules they recommend are CT8112843 or CT9158728. The CT16G4SFD8213 is not listed.

 

My x270 came pre-installed with one 16GB DDR4-2133MHz SODIMM. But without opening the case I cannot easily identify what brand it is. Not all DDR4-2133MHz SODIMM's behave the same and I would trust the Crucial Advisor tool at www.Crucial.com.
