The AsRock E3C256D4U-2L2T is a Micro-ATX server motherboard built around a single Socket H5 (LGA1200) CPU socket — a board sized and specced for rack-mount and compact tower server builds where you need workstation-class expansion without a full-ATX footprint. At 11.89 x 11.14 inches, E3C256D4U-2L2T fits standard Micro-ATX chassis openings, which matters when you're planning rack density or retrofitting an existing enclosure rather than building around a nonstandard board.
This is a single-socket LGA1200 platform, the socket used by recent-generation Intel Xeon E-series and desktop-class CPUs in server-oriented designs — the right layout for edge servers, small-business file/application servers, or dedicated recording and management servers where a full dual-socket board is more than the workload needs. E3C256D4U-2L2T (often searched as E3C256D4U 2L2T) ships at 3.31 lb, light enough that shipping and rack-install handling are straightforward compared to full-size dual-socket boards.
At 2.76 inches of stack height plus the 11.89 x 11.14 in footprint, confirm chassis clearance before ordering — Micro-ATX rack cases and compact towers vary in standoff spacing and expansion-slot cutouts. Pair this board with a Micro-ATX-compatible chassis and a cooler rated for the LGA1200 mounting pattern. If you're speccing a recording server or NVR-class build around this board, review your network video recorders and server hardware lineup to confirm the rest of the platform — CPU, RAM, and storage controller — matches your workload before finalizing a bill of materials. For broader platform planning, a VMS architecture guide is worth reviewing if this board is going into a video management or recording role.
E3C256D4U-2L2T is manufactured in China (CN), per country-of-origin data on file — relevant if your procurement process tracks origin for compliance or import documentation.
Manufacturer specification sheets for E3C256D4U-2L2T list full chipset, memory, and I/O detail beyond what's verified here; confirm exact RAM type/capacity, expansion slots, and onboard networking against current AsRock documentation before finalizing a build-out, since those details were not available in the verified data used for this listing.

Q: Where is the E3C256D4U-2L2T manufactured?
A: China (CN), per country-of-origin data on file.
The E3C256D4U-2L2T is a single-socket LGA1200 Micro-ATX board, and the socket callout alone tells you what generation of server build this targets — this isn't a dual-socket monster, it's the compact platform for a single-CPU edge or departmental server.
Technical Highlights:
Deployment Considerations:
This board fits best in single-CPU edge server or small recording-server builds where a full dual-socket Micro-ATX or ATX platform would be overkill for the workload.
