Because E93839 is a regulatory mark, many different motherboard models for various computer brands carry this UL number. This explains the wide range of conflicting information online. Here is a master list of motherboards commonly associated with the E93839 marking:

: Many repair forum posts date back to 2016-2021, and some shared resources may have been lost or removed due to platform changes or copyright claims.

: Some users have attempted to install 4th generation Core processors on older LGA 1155 or LGA 1156 E93839 boards, discovering that a socket generation mismatch makes this impossible.

Replacing a Dell or HP motherboard in a standard case can be difficult because of proprietary connectors. One user wanted to install a Dell E93839 GA0402 board (normally from an OptiPlex 760) into a GX620 case. He discovered that the front panel pinout didn't match and needed a diagram to rewire the connections for power, USB, and audio.
