OEMs like HP and Acer publish limited CPU support lists. Based on real-world testing and official documentation from HP EliteDesk 800 G1 (which uses a variant of MS-7869), here are the :
The first major limitation is the BIOS (Basic Input/Output System). Unlike retail motherboards from ASUS or Gigabyte, which receive regular microcode updates for a wide range of CPUs, the MS-7869 is locked to a vendor-specific BIOS. Manufacturers often disable support for certain processors—even those physically compatible with the socket (LGA 1150)—to differentiate product tiers. For instance, while the chipset may support Xeon E3-1200 v3 series CPUs, the BIOS on the MS-7869 almost universally blocks them. This software-level gatekeeping ensures that a budget office PC cannot be easily transformed into a workstation. ms-7869 ver 1.0 cpu support
This motherboard supports a range of 4th Gen Intel processors. While it can technically house any LGA 1150 chip, it is limited by the system's power delivery and BIOS. MS-7869 ver 1.0 motherboard overclock Aspire xc-605 OEMs like HP and Acer publish limited CPU support lists
