What the Xeon E-2134 is
The Xeon E-2134 is a four core, eight thread workstation processor with a 3.5 GHz base and up to 4.5 GHz turbo. It carries 8 MB of Smart Cache and a 71 W TDP on the 14 nm process. Intel announced it on July 12, 2018 with the E-2100 series for entry workstations.
It has no integrated graphics: the ARK page carries no graphics section and the database graphics claim conflicts with it, so this page follows ARK with None. A separate card is required even for setup displays. Four cores with Hyper-Threading cover CAD viewing and office servers where ECC matters.
ECC memory support corrects single bit errors during long jobs. The multiplier is locked at 35 times the 100 MHz base clock. Launch pricing is left out here because ARK publishes no current figure.
Socket and motherboard compatibility
The E-2134 fits LGA 1151 revision 2 on workstation boards with the C242 and C246 chipsets. Consumer 300 series boards are not the target, since ECC wiring lives on the workstation boards. Check the board maker CPU list for the exact E-2134 before ordering.
It does not fit 100 or 200 series boards, which are revision 1 for 6th and 7th Gen chips. A graphics card is mandatory, so pick a board with the PCIe x16 slot wired at full speed. The Intel Xeon E-2124 is the four thread sibling on the same boards at lower cost.
Boards sold after mid 2018 accept it with the shipping BIOS where the maker lists the part. Entry towers with a basic workstation card suit single threaded CAD beside ECC safety.
Memory, PCIe and cooling
Memory support is DDR4-2666 in two channels up to 128 GB, with ECC correcting single bit errors. Intel notes the 128 GB level needed a 2019 BIOS update on supporting boards. Two matched ECC UDIMMs give dual channel speed with error cover.
PCI Express arrives as version 3.0 with 16 lanes from the CPU for graphics and storage. A workstation card and an NVMe drive fit the lane budget of an entry tower. Cooling uses the shared 75 mm LGA 1151 pattern at 71 W.
Upgrade paths
On the same socket the step up is a six core E part such as the Xeon E-2146G where threads matter, keeping the board and ECC DDR4. The E-2134 keeps its place where a fast quad core covers single threaded work without paying for graphics silicon.
Moving past LGA 1151 means a new board on a current workstation platform. Owners usually add ECC memory or a faster workstation card before replacing the processor.
Frequently asked questions
What socket does the Xeon E-2134 use?
It uses LGA 1151 revision 2 on C242 and C246 workstation boards. Consumer 300 series boards are not the target.
How many cores does the E-2134 have?
Four cores with Hyper-Threading give eight threads at 3.5 GHz base with up to 4.5 GHz turbo, with 8 MB of cache at 71 W.
Does the E-2134 have integrated graphics?
None. The ARK page carries no graphics section, so a separate card is required even for setup displays.
What memory does the E-2134 support?
DDR4-2666 in two channels up to 128 GB with ECC for error cover on long jobs.
How does the E-2134 differ from the E-2124?
The Intel Xeon E-2124 runs four threads without Hyper-Threading on the same boards. The E-2134 adds threads for multitasking.
