Hello there,

 

I have two laptops that were working slowly. Same manufacturer, same model; Lenovo Thinkpad E560. They were running multiple programs at the same time and checking performance options noticed that the memory was 95% to 100% constantly. CPU, Disk and Network were fine. They came with a 4 Gb RAM module so I decided to install a second identical 4Gb RAM module to double the memory. I have included the photos of both sides of the RAM module for you to see.

 

After installing the second module the POST test was ok, the laptops boots fine, Windows 10 Pro 1703 loads without problems and when checking on Settings -> System -> About, the Installed RAM showed as 7.9 Gb of RAM. The laptops were working for 5 hours under heavy usage and then they freeze. What I mean by Freez is not that I have a BSOD or a crash to a black screen or some type of error. They just freeze, you can see all the programs that were running at the moment. If there was a windows with a progress bar (download, file copy, some sort of process), it just freeze. The mouse cursor doesn't move, the keyboard dosn't work, if there was a video it just freeze, nothing happens. Is as if you put the computer in pause. So the laptops have to be forcefully reset pressing and holding the power button.

 

Again both RAM modules were identical but for troubleshooting I decided to purchase two new single 8Gb RAM modules of the same specs one for each laptop: DDLR3L - 1600 SODIMM 1.35V. The only difference is that they are 8Gb instead of 4 Gb. I also included photos of the case were they came for you to see. So I removed both 4Gb RAM modules and installed the single 8Gb RAM module on both computers. The POST test was ok, the laptop boots fine, Windows 10 1703 loads without problems and when checking on Settings -> System -> About, the Installed RAM showed as 7.9 Gb of RAM. This time the laptops were working for 6 hours under heavy usage and then they freeze. Same symptoms the laptops just stood still nothing can be done but to force a reset. This is happening on two different laptops of the same manufacturer/model. This was not happening when they have the original 4 Gb RAM module, they were working slow but they were not freezing.

 

You will see three photos, two photos of both sides of one of the 4Gb RAM modules and one photo of the case were the 8Gb RAM module came. Don't pay attention to what I wrote on the case. Is just that I put the 4 Gb modules in the case and to not get confused I wrote that.

 

Any ideas how to fix this?

Hey no ideas?

 

I was able to take photos of the 8 Gb module. Included are both sides of one of the modules. Any suggestions?

So you're having the same issue on more than one laptop at the same time?

I ran the utility in only one computer because the other one has been working without freezing. Anyways the other one is identical in components. Lenovo Thinkpad E560.
