Ram Compatibility

Product: HP Pavilion Gaming Laptop 15-ec2087AX (46R32PA)

OS: Windows 11 version 25H2

Hello,

I recently installed a new Kingston 8GB DDR4 3200MHz SODIMM module (Part Number: 9905711-037.A00G) alongside my existing SK Hynix 8GB DDR4 3200MHz SODIMM module (Part Number: HMA81GS6DJR8N-XN). After installing the new RAM, my laptop fans have been noticeably louder, and I have started experiencing frequent FPS drops while playing games such as Valorant and CSGO. These issues did not occur prior to the upgrade.

I would like to ask if this could be caused by a RAM compatibility issue between the two modules.

Any fix or recommendation would be very appreciated.

Thanks!

This is possibly an overheating problem.  I assume the bios does NOT show the fans running %100.

Use an air duster to clean the fans and consider getting a laptop cooler.

Verify the new ram by removing the original and see if the problem goes away.

Verify ram speed by running the WMIC app.

An easy way to find what memory you have is to run the wmic app from the windows command prompt. Bring up the window CMD prompt and enter the first line to see what memory you have. The second line may give the maximum memory possible based on the chipset. The number of memory sockets limit what can be added.

wmic memorychip get devicelocator, capacity, speed, MemoryType, formfactor, partnumber, manufacturer

wmic memphysical get maxcapacityEx, MemoryDevices

Should look something like the following. To purchase identical memory search for the part number shown and look for the letters 'HP' on any label attached to the memory stick.

The above values are in bytes. Divide by 1024 twice to get megabytes.
8589934592/(1024*1024) = 8192mb or 8gb

The output of maxcapacityEx is Kbytes, not bytes.

Note that some older systems do not recognize maxcapacityEx even when running latest Windows.

Let me know what you find out.

Note that filling all memory channels doesn't double the speed of RAM, but it does double the memory bandwidth in a dual-channel setup, meaning the system can transfer data more efficiently. The actual performance gain is not a full 2x  and varies depending on the application, with the most noticeable improvements seen in high-demand tasks like video editing, rendering, and gaming with integrated graphics.

Hi, thanks for the reply.

To answer your first question, no — my BIOS doesn’t allow any adjustments to fan settings. The only related option is “Fan always on.”

As for dust, my fans and vents look clean and dust-free.

I tried troubleshooting by running the laptop with only the Kingston RAM installed, but the issue still occurs. When playing Valorant, the FPS drop happens consistently every round.

I also ran the WMIC commands you mentioned. Here’s the output from my Command Prompt: 

Let me know if you spot anything unusual or if this helps narrow down the issue. Thanks again for the guidance.
