Good Evening,

I am attempting to upgrade my Oman 870-244. It came with 2x8gb DDR4-2133mhz. What can I do for an upgrade?

make sure you buy a kit and not just a pair of memory.

a kit is guaranteed to work

Thank You for the response. I have already installed 64GB 3600MHz (kit of 2 sticks). It seems my PC is only working at 2133MHz. I have updated BIOS and all drivers with no luck. Despite what YouTube says, I am not able to change the RAM in BIOS. I could not find that option. Am I just stuck with 2133? Not sure what else to do.

The spec for your system is here (use Firefox as it is not https)

If you got 64gb to work then you are lucky as only 32gb was recommended!

Memory upgrade information

• Dual channel (2 DIMMs per channel) memory architecture
• Four DDR4 DIMM (288-pin) sockets
• Supports PC4-17000 (DDR4-2133)
• Supports 4 GB and 8 GB DDR4 DIMMs
• Supports up to 4 GB on 32-bit systems

  note:

  32-bit systems cannot address a full 4.0 GB of memory.

• Supports up to 64 GB (unbuffered) on 64-bit computers

  note:

  HP has tested a maximum of 32 GB on this system and does not recommend maximum memory beyond the 32 GB

Note that the memory is accessed two at a time so the effective speed is 2x2133 = 4266

There has been no bios release since 2019 so any memory improvements since then like xmp 2 or 3 are not in the bios.
