If you own one of these, you have the FXM1 board: hp fxn1 e93839 motherboard specs 2021
This article provides a comprehensive breakdown of every specification, compatibility note, and upgrade path for the HP FXN1 (also stamped as E93839) as documented throughout 2021.
It uses SO-DIMM slots (laptop-style RAM) rather than standard DIMMs. This saves space but limits you to standard JEDEC speeds. While the board can handle 3200MHz RAM, it will often downclock to 2666MHz or 2933MHz depending on the specific CPU installed (i5 vs i7). Intel 2nd and 3rd Generation Core i3, i5,
Avoid. No PCIe slot for a GPU, and the VRMs cannot handle sustained 100% CPU load.
