What the Xeon E-2224 is
The Xeon E-2224 packs four cores into a 71 W entry workstation envelope. It launched in May 2019 with a 3.4 GHz base and up to 4.6 GHz boost. Intel positions it as the starting point for single socket servers and CAD workstations that need ECC without extra cores.
Eight megabytes of Smart Cache support office multitasking and light CAD across four threads. There is no Hyper-Threading on this SKU, so four cores give four threads. The high base clock holds speed under sustained single thread work such as modeling kernels.
There is no integrated graphics on this version, so a discrete GPU or board BMC is required for display output. The process is 14 nm and the multiplier is locked. ECC memory is supported, which separates it from consumer Core i3 parts on the same socket.
Socket and motherboard compatibility
The E-2224 fits the LGA 1151 socket on revision 2 boards only. Workstation makers list it with C242 and C246 boards that provide ECC UDIMM slots and workstation I/O. Consumer 300 series boards may boot it where the maker lists support, but ECC only activates on C242 and C246.
Boards accept the chip with the shipping BIOS where the support list includes it. Early C246 boards from 2018 may need an update for E-2200 IDs. Revision 1 boards with 100 or 200 series chipsets never support it. The Socket vs chipset: what decides whether a CPU works guide explains the revision split behind board choice.
Single socket operation is the only option. There is no dual socket path for Xeon E, so growth means a larger Xeon Scalable platform instead.
Memory, PCIe and cooling
DDR4-2666 ECC UDIMMs in two channels up to 128 GB are the entry workstation memory. Two matched modules give dual channel bandwidth near 42.7 GB per sec for large assemblies. Builders who run virtual machines should order 32 GB or more from the start, since ECC UDIMM pricing rewards planning.
PCIe arrives as 16 Gen3 lanes from the CPU for a GPU or NVMe plus platform lanes from C242 and C246 for storage and networking. A mid range workstation card or 10 GbE adapter fits the CPU slot in most tower builds. Exact slot wiring follows the board manual.
Cooling uses the 75 mm LGA 1151 pattern from the CPU cooler compatibility by socket guide. Boxed versions include a thermal solution, while tray versions need a tower or stock cooler rated for 71 W. Keep vents clear in small towers where the GPU shares airflow.
Upgrade paths
On the same socket, the Intel Xeon E-2236 raises the count to six cores with Hyper-Threading at 80 W for heavier multitasking. The Intel Xeon E-2244G adds integrated graphics at 71 W for builds that need display output without a discrete card. Both fit C242 and C246 boards after a BIOS check.
Desktop Core i5 parts such as 9th Gen i5 chips give similar quad core speed without ECC for one off builds. They suit labs rather than fleets where error correction matters.
Past LGA 1151 a new board is required, since later Xeon E families moved to LGA 1200. The E-2224 covers entry workstations where four cores must run with ECC for years, and only a larger core budget justifies replacing it.
Frequently asked questions
What socket does the Intel Xeon E-2224 use?
It uses LGA 1151 on revision 2 boards with C242 or C246, written FCLGA1151 in Intel documents.
How many cores does the E-2224 have?
Four cores without Hyper-Threading give four threads. Base is 3.4 GHz with boost to 4.6 GHz.
Does the E-2224 include integrated graphics?
No. It needs a discrete GPU or board BMC for display. G suffix SKUs such as the E-2224G add UHD Graphics P630 instead.
What memory does the E-2224 support?
DDR4-2666 ECC UDIMMs in two channels up to 128 GB. ECC only activates on C242 and C246 boards.
When did the E-2224 launch?
May 2019 in the second quarter of 2019, as the entry Xeon E-2200 for single socket workstations.
