Dual-socket Xeon Gold 6142 server

The DELL PowerEdge R740 is a 2U rack server fitted with two Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. It targets organisations that need dense compute for virtualisation, databases or high-performance workloads in a standard rack footprint. The platform supports up to two processors and 24 DDR4 memory slots.

H730P controller and quad-port networking

The bundled PERC H730P 2 GB controller adds RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through modes with battery-backed cache. An Intel X520/I350 daughter card supplies two 1 GbE and two 10 Gb SFP+ ports, while iDRAC 9 Enterprise enables full out-of-band management. Redundant 750 W platinum power supplies and ready rails complete the package.

768 GB DDR4 with 3 TB ceiling

The system ships with 768 GB of registered ECC DDR4-2666 across all 24 slots, leaving no free DIMM positions for expansion without replacing modules. Maximum supported capacity is 3 TB, so memory-heavy workloads can grow substantially. Eight 2.5-inch SAS/SATA trays are present but empty, so storage capacity depends entirely on the drives you add.

Questions about this item

How many DDR4 slots remain free for future memory upgrades?

All 24 DDR4 slots are populated with 32 GB modules to reach 768 GB, so adding capacity requires replacing existing DIMMs.

Which component will hit its ceiling first during sustained heavy workloads?

The PERC H730P controller tops out at 12 Gb/s SAS/SATA throughput, which can become the bottleneck before the dual Xeon Gold 6142 CPUs reach full utilisation.

How loud and hot does the chassis get when running 24/7 with both 750 W power supplies active?

Redundant 750 W platinum supplies and hot-swap fans keep temperatures stable, but the 2U rack form factor means audible fan noise in quiet office environments.
