What the Xeon E-2378 is

The Xeon E-2378 is an 8-core server processor that Intel released in September 2021 with the Xeon E-2300 range. Its Cypress Cove cores run 2.6 GHz base to 4.8 GHz turbo with Hyper-Threading for 16 threads. Cache is 16 MB of Intel Smart Cache.

The chip pairs 8 cores with a modest 65 W envelope for hosts that run many services together. The lower base clock keeps heat down, while turbo still reaches 4.8 GHz for short tasks. 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-2378 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 names the C250 series as the matching server chipsets for this exact model.

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 moving within the same board to a higher clock 8-core E model rather than adding 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. Dense hosts often use 2 by 32 GB ECC UDIMM for guests 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 i7-11700, the E-2378 adds ECC server support with similar 8-core layout. The desktop i7 part suits creation 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-2378 fits a virtual host, a file server, or a backup node with several services.

For used buyers, the 8-core E without graphics makes sense when the board has BMC video. When setup without a card matters, the G model with P750 graphics is the safer pick on the same board.

Frequently asked questions

What socket does the Intel Xeon E-2378 use?

It uses LGA 1200, written FCLGA1200 in Intel documents, on C252 or C256 server boards.

How many cores does the Intel Xeon E-2378 have?

8 cores with 16 threads, 2.6 GHz base and up to 4.8 GHz turbo, with 16 MB of Intel Smart Cache.

What memory does the Intel Xeon E-2378 support?

DDR4 up to 3200 MT/s with ECC in two channels, up to 128 GB. ECC guards data in server use.

What graphics does the Intel Xeon E-2378 include?

None on the chip. Setup needs a separate card or board BMC graphics.

What is the TDP of the Intel Xeon E-2378?

65 W. A 1U or tower server cooler with directed airflow suffices.
