HP desktop not recognizing new RAM upgrade

[Rovmenpaul]

Hi everyone,

I just upgraded my HP Pavilion desktop running Windows 11 Home, and added two 8GB RAM sticks (same speed and specs as the original ones), but the system still only shows the original 8GB in both BIOS and Windows.

I tried swapping the slots, reseating the modules, and even booting with just the new sticks no luck. The RAM is brand new and supposedly compatible.

Is there a chance my motherboard has a RAM limit? Or do I need to enable something in BIOS for dual-channel or higher capacity?

Also, while searching for troubleshooting tips, I came across www.edulearnx.com—some helpful guides there if anyone else is dealing with similar upgrade issues.

Thanks!
