BSOD (Kernel Security Check Failure) after upgrading RAM of two laptop

I have two old laptops, Acer Aspire 5470 and Toshiba Satellite C660.

On both the links you can see the maximum RAM supported is 8 GB. So I got two 8 GB sticks, these ones to be specific:
DDR3L-1600 SO-DIMM
And I removed the old 2 GB sticks.


When I put either of the RAM chips into both of the laptops, I get a BSOD saying "Kernel Security Check Failure" 3 seconds after seeing the Windows logo.
Interchanging the RAM chips causes the same issue on both laptops.

I have an All-In-One PC which has the same RAM type, so I put them in those to check if they were working, and both RAMs were working fine and Windows 10 booted up normally.

In the BIOS, I can see installed RAM as 8 GB but Windows keeps crashing when trying to boot. I even decided to reinstall Windows using the latest ISO but when I USB boot, I get the same BSOD right after the Windows logo.


Am I doing something wrong? Did I miss something? Did I buy the wrong chip?

According to the specs for the Aspire, the ram should be 1066, not 1600.

• Max Supported Size
  8 GB
• Technology
  DDR3 SDRAM
• Speed
  1066 MHz
• Form Factor
  SO-DIMM 204-pin
• Slots Qty
  2

Also, it looks like the max is 8GB which may be 2x4GB, not a single 8GB DIMM.

• Memory Speed
  1066 MHz
• Configuration Features
  2 x 2 GB
• Technology
  DDR3 SDRAM
• Installed Size
  4 GB

Oh..... I see...

Thank you for your response kind sir.

I thought the speed won't matter and the RAM would just run at a lower frequency of 1066 MHz. I guess I was wrong.

Sometimes true, sometimes not. In your case it appears not unfortunately. I'd RMA the new memory and get the correct ones. Also, find out if that computer will accept 8GB DIMMs as what I read seems to indicate max memory is 8GB which would mean 2 4GB DIMMs.

I see.
Thank you.

The laptops are really old. Even searching anything about them is really difficult at this point.
