What the Xeon E-2336 is
The Xeon E-2336 is a 6-core server processor that Intel released in September 2021 with the Xeon E-2300 range. Its Cypress Cove cores run 2.9 GHz base to 4.8 GHz turbo with Hyper-Threading for 12 threads. Cache is 12 MB of Intel Smart Cache.
The chip balances core count and 65 W heat for small hosts that run several services together. The 12 MB cache helps virtualized roles that reuse data across guests. The 14 nm process and locked multiplier keep the focus on steady single socket use.
There is no integrated graphics on this model, so setup needs a separate card or board BMC graphics. ECC memory support guards data in long running systems. The socket package is FCLGA1200 at 37.5 × 37.5 mm.
Socket and motherboard compatibility
The E-2336 fits the LGA 1200 socket. Entry server boards with C252 and C256 chipsets accept it with the shipping BIOS. The Intel E-2378 compatible list shows the C250 series as the matching server chipsets for this family, and the same boards cover the 6-core E models.
Desktop chipsets are not the intended home for ECC server use. A buyer who needs error correction should choose a C252 or C256 board with ECC UDIMM support. The board maker CPU support list names the minimum BIOS for the E-2300 range.
Single socket operation is the only option. Growth means a larger single chip on the same board rather than a second socket.
Memory, PCIe and cooling
The memory controller supports DDR4 up to 3200 MT/s in two channels, up to 128 GB, with ECC support. Small hosts often use 2 by 16 GB ECC UDIMM for integrity with room to grow. The controller does not accept DDR5.
The CPU supplies 20 PCIe 4.0 lanes: x16 plus x4 from the processor. Entry hosts use the lanes for network cards and fast SSD storage. The board specifications state which slots reach full speed.
At 65 W, a 1U or tower server cooler with directed airflow suffices. Mounting uses the 75 mm LGA 1200 pattern from the CPU cooler compatibility by socket guide. Rack airflow matters more than cooler mass in shallow chassis.
Upgrade paths
Against the Intel Core i5-11400, the E-2336 adds ECC server support with similar 6-core layout. The desktop i5 part suits office towers, while this server part suits small hosts with error correction. Both share the same socket but target different boards.
Moving to a newer server platform needs a new board and memory generation. The E-2336 fits a branch office host, a file server, or a monitoring node with several services.
For used buyers, the 6-core E without graphics makes sense when the board has BMC video. When setup without a card matters, a G model with P750 graphics is the safer pick on the same board.
Frequently asked questions
