How to Identify Low Density Laptop RAM
You can identify low-density laptop RAM modules by checking the part number located on the module. This part number contains the relevant information for determining the memory density of memory chips on your module. Identifying the density of a RAM module is crucial for ensuring that you are not inserting incompatible memory into your machine.

2
Find the segment of the part number containing the description of the RAM chips. This is typically the first portion of the part number, and consists of a character sequence such as "32Mx8" or "32Mx16."

Identify the density of your RAM chips with the number following the "x" in the part number. Low-density RAM is identified with an "8" after the "x," while high-density RAM is identified with a "16." So a RAM chip with a description of "32Mx8" is a low-density module, while one with a description of "32Mx16" is a high-density module.

Tips & Warnings
If you install high-density RAM in a laptop that cannot support it, you may encounter issues with your laptop's motherboard only recognizing half of the RAM. For example, if you install a 1 GB high-density RAM module in a laptop that does not support it, your laptop may only see 512 MB of that RAM, or may sometimes not recognize the RAM at all.
