I've been struggling to get my HP desktop to utilize its RAM speed fully, and it's really frustrating. I discovered that the issue lies with the HP BIOS, which doesn't allow me to take advantage of the hardware I have. I'm wondering if there are any compatible BIOS options out there that would work well with Linux while allowing me to unlock the full RAM speed.

BIOS settings are independent of the operating system you choose. HP BIOS tends to be pretty limited because you're using their motherboard. You can't just install a BIOS from another board on an HP board. Your motherboard has a max speed limit, and that's all it can do. I suggest looking up your motherboard specs online to see what speeds it supports. If your RAM speed exceeds that, it will automatically downclock.
You might need to provide more details. RAM tends to be rated for max speeds, which typically require overclocking to achieve. Your PC will decide the actual speed it runs at. Also, you can't run any BIOS other than the one designed for your specific HP machine. If you’re looking to overclock, you might want to rethink getting an HP.
Yeah, I ran into the same problem. HP BIOS typically locks RAM speeds to ensure stability. Some folks have had success using modded BIOS from similar model computers, but you have to be cautious and check for Linux compatibility first to avoid any boot issues or crashes.
This is indeed an HP OEM lock issue. The standard for most Corsair kits at 3200 MHz is XMP at 1.35V, not the JEDEC base. If your board is hard locked at 1.2V with no XMP option, it’ll default to speeds like 2133 or 2400, regardless of what it’s labeled. If you want to keep your current setup, look for RAM that has a JEDEC profile of 3200 MHz at 1.2V (usually CL22). Anything marketed as 3200 XMP will likely downclock on HP boards, which is pretty frustrating.
