Subject: Inquiry Regarding RAM Compatibility for HP Pavilion Gaming Laptop

Dear Support Team,

I trust this message finds you well. My name is Sasha, and I am seeking assistance with a potential RAM upgrade for my HP Pavilion Gaming Laptop (model: 15-cx0xxx). After inspecting my current system, here is the accurate information about the existing RAM modules:

Current RAM Configuration:

  • Slot #1:

    • Type: DDR4
    • Size: 4 GB
    • Channels: Single

    • Channels: Single
    • Max Bandwidth: DDR4-3200 (1600 MHz)
    • Part Number: 4ATF51264HZ-3G2J1

The total RAM size is 8 GB (4 GB in each slot). I am interested in upgrading to the Gigastone Laptop RAM 16GB DDR4-2666MHz SODIMM. Before proceeding with the purchase, I would like to confirm the compatibility of this RAM module with my current setup.

Considering the details of my current RAM, could you please confirm whether the Gigastone RAM module is compatible with my HP Pavilion Gaming Laptop 15-cx0xxx? Additionally, if there are any specific recommendations or considerations regarding RAM upgrades for this model, I would greatly appreciate your guidance.

Thank you very much for your time and assistance. I look forward to your prompt response.

Best regards,Sasha Orel email: [Personal Information Removed]

Hi, Sasha:

 

Chapter 1 of the service manual indicates the maximum memory is 2 x 8 GB:

Since you want to install a 16 GB memory chip in each slot, I recommend that you run this command first to see if that would be possible:

 

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

 

This will open the command prompt.

 

2. After the 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.

 

The Gigastone DDR4-2666 MHz memory you are interested in buying should work if it has a CL specification of 19.
