Bushido publishes the standard bill of materials above. For substitute part chains, current pricing, and serial- or service-tag-specific configurations, go straight to the manufacturer's own portal — the authoritative source. We don't scrape or resell parts data, and we earn nothing from these links.

Dell — official sources

Independent cross-reference — not affiliated with Bushido

Dell does not publish a public substitute cross-reference — alternate-part chains live in Dell's internal service systems. Use the Service Tag lookup for the original BOM, then the third-party cross-reference below for substitutes.

No single manufacturer publishes a cross-vendor "alternative parts" list, and no one official aggregates across all vendors. Lenovo and HPE expose substitute chains publicly; Dell and Sun/Oracle keep them internal or gated. These links are the honest map of where each vendor's data actually lives. If a link is dead or a portal has moved, tell us and we'll fix it.

Standard Bill of Materials (at GA)

The Dell EMC PowerEdge R740 base configuration at general availability (Q4 2017) shipped as a 2-socket, 2U rack server built around the 2nd Generation Intel Xeon Scalable processor family. The base SKU included one Intel Xeon Silver 4114 (10-core, 2.2 GHz, 85 W) with a second CPU socket populated for dual-socket builds, two 16 GB DDR4 RDIMM 2666 MT/s modules (across 24 available DIMM slots supporting up to 3 TB with LRDIMMs), a PERC H740P Mini RAID controller with 8 GB NV cache, two 750 W Platinum-rated hot-plug redundant power supplies, a Broadcom 5720 quad-port 1GbE LOM network daughter card, iDRAC9 Express embedded management with a dedicated 1GbE port, and ReadyRails II tool-less sliding rail kit. The server supports up to 16 x 2.5-inch SAS/SATA/NVMe hot-plug drives or 8 x 3.5-inch drives, up to 8 PCIe Gen3 expansion slots, and up to three double-width GPUs or six single-width GPUs for accelerated workloads.

BOM reflects the standard base configuration at GA (Q4 2017). Non-standard CPU SKUs, GPU configurations, larger drive bay chassis variants, and factory-OS installs are not fully enumerated. Part numbers shown are Dell order codes valid at GA; service-part numbers may have been superseded. Always cross-reference with Dell's spare-parts portal or PartnerDirect before ordering. The R740 shares a BIOS firmware image with the R740xd, R640, R940, and Precision 7920R.

BOM is AI-synthesized from public datasheets. Cross-reference with the vendor's spare-parts portal before ordering.
