What the Xeon D-1540 is
The Xeon D-1540 is an 8 core Broadwell-DE SoC on BGA 1667 for edge virtualization hosts. Intel set 8 cores and 16 threads at 2.0 GHz base with turbo to 2.6 GHz. Twelve megabytes of Smart Cache cover guests. Power is 45 W on 14 nm from March 2015.
Eight cores double threads per socket over 4 core SoCs for consolidation at the edge. Turbo lifts bursts while all core loads hold base. Integrated 10 GbE cuts NIC costs. The single socket design suits micro data centers.
DDR4 and DDR3 ECC over two channels to 128 GB feed guests. ECC protects edge data. Buyers pick the D-1540 where 8 cores must fit 45 W with networking on package.
Socket and motherboard compatibility
The D-1540 solders to BGA 1667 with 45 W board cooling. No later swap exists. Edge hosts lock memory and flash at deployment. Vendors qualify the integrated NICs with common hypervisors.
SoC integration keeps boards compact for short depth chassis. The LGA, PGA and BGA: CPU package types explained guide explains soldered server consequences. Check hypervisor driver lists for the on package NIC.
Memory, PCIe and cooling
DDR4 to 2133 MHz and DDR3 ECC over two channels to 128 GB suit edge VMs. Two channels feed eight cores with fair sharing. ECC is required.
PCIe 2.0 and 3.0 with up to 32 lanes serve NVMe caches and expansion. Onboard 10 GbE handles cluster traffic. A small NVMe pool accelerates edge storage.
Cooling uses 45 W board heatsinks with chassis fans. Eight cores run warm under full load. Airflow planning beats turbo expectations.
Upgrade paths
No soldered upgrade exists. Compare the Intel Xeon D-1548 at the same clocks nearby or the Intel Xeon D-1541 at 2.1 GHz to 2.7 GHz above. All share BGA-1667.
A newer Xeon D needs a new board. The How to find your CPU socket type guide helps identify soldered edge hosts.
