Intel Xeon E3-1220 v5 SR2LG 3.0GHz LGA1151 cpu accessory

SKU CH-A8Z0-1FH5E

A 3.0GHz quad-core Xeon for LGA 1151 C230 boards, supporting 64GB ECC DDR4-2133 or DDR3L-1600 with no integrated graphics

  • Quad-core design handles parallel workloads
  • LGA 1151 socket fits C230 chipset motherboards
  • Supports 64 GB DDR4-2133 or DDR3L-1600 ECC memory
  • 14 nm process delivers efficient performance per watt
  • Dedicated GPU required — no integrated graphics

Server processor for entry workstations

The Intel Xeon E3-1220 v5 is a 3.0 GHz quad-core processor built for LGA 1151 platforms that require ECC memory support. It targets budget servers, workstations and light computing tasks where data integrity matters more than raw thread count. The part is new and ships without integrated graphics, so a discrete GPU is mandatory for any video output.

LGA 1151 socket with C230 series chipset requirement

Compatibility hinges on the motherboard chipset; this CPU only works with C230 series boards despite sharing the LGA 1151 physical socket. Memory support tops out at 64 GB of DDR4-2133 or DDR3L-1600 ECC, and the locked multiplier prevents overclocking. PCIe Gen 3.0 lanes handle storage and expansion cards at standard server speeds.

Steady throughput under continuous load

The 14 nm process delivers consistent performance per watt during sustained workloads such as file serving or light virtualisation. Four threads without hyper-threading limit parallel throughput, so heavily multi-threaded tasks will queue rather than scale. Thermal output remains predictable, making the processor suited for always-on environments that prioritise stability over burst speed.

Questions about this item

What does the 3.0 GHz base clock mean for everyday server workloads?

The quad-core Xeon E3-1220 v5 runs at a steady 3.0 GHz without Turbo Boost, giving predictable performance for file serving, light virtualization or web hosting where sustained throughput matters more than burst speed.

How does the PCIe Gen 3.0 interface limit expansion cards in practice?

The processor provides 16 lanes of PCIe 3.0, so a single GPU or RAID controller will operate at full Gen 3 bandwidth, but adding multiple high-speed devices will share those lanes and reduce per-slot throughput.

What motherboard and cooler clearance does the LGA 1151 socket require?

You need a C230-series chipset board with an LGA 1151 socket; the CPU uses the standard square ILM mounting holes, so any cooler rated for LGA 1151 with a 65 W TDP rating will fit physically.
