Maximum RAM Upgrade capacity for HP Notebook 15-da2012tu

[el_castro]

I have HP Notebook - 15-da2012tu with 

Memory

4 GB DDR4-2666 MHz RAM (1 x 4 GB) Transfer rates up to 2666 MT/s. 1 x 4 GB

Processor

Intel® Core™ i5-10210U (1.6 GHz base frequency, up to 4.2 GHz with Intel® Turbo Boost Technology, 6 MB L3 cache, 4 cores)

I want to know the maximum RAM capacity supported in this model. Is it 8GB x 2 = 16GB or higher? And also I want to know whether we can insert different RAM capacity sticks like 4GB + 8GB to make it a total 12GB.

HP only has the service manual for the older model series available.

HP 15 Laptop PC Maintenance and Service Guide

Chapter 1 has the memory upgrade information.

Your notebook uses DDR4-2666 MHz CL19 memory.

You can also use DDR4-3200 CL22 memory which will automatically bridge to 2666 MHz.

You should be able to install up to 2 x 16 GB of memory in your notebook and you can run this command to confirm that:

1. In the search box, search for cmd and click Run as administrator.

This will open the command prompt.

2. Once command prompt is opened, type wmic memphysical get maxcapacityEx and press the enter key.

There, it will show the maximum RAM capacity your PC's motherboard can support.

The capacity is shown as Kilobytes, so you have to convert it to Gigabytes by dividing the number provided in the report by 1,048,576.

If you want to install memory in mismatched capacities as in the example you wrote, that would be fine but bear in mind that the memory will only run in single channel mode.

In order for memory to run in the higher performing dual channel mode the memory chips have to be installed in matching capacities in each slot (2 x 4 GB, 2 x 8 GB, 2 x 16 GB).
