Dell PowerEdge R740 2U Server

The Dell PowerEdge R740 is a 2U rack server built for virtualization and database workloads. It ships with two Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. A PERC H730P controller manages the two installed 400 GB SATA SSDs.

Suits dense compute needs.

This server suits teams that need high core counts and large memory capacity in a compact 2U form factor. The dual-socket design supports demanding multi-threaded applications and virtualization clusters. Buyers who require multiple double-width GPU accelerators should look elsewhere, as the 2U chassis limits add-in card space. It also does not fit environments restricted to tower or pedestal form factors.

512 GB DDR4 2666 MHz registered ECC memory

The installed memory totals 512 GB using sixteen 32 GB DDR4 2666 MHz registered ECC DIMMs. This configuration fills 16 of the 24 available slots, leaving room for expansion up to the 3 TB maximum. Registered ECC modules are required for compatibility; standard unbuffered DDR4 will not work in this platform.

Questions about this item

How should I choose between the 20-core and other core-count versions of the Xeon Gold 6148?

This server ships with two Xeon Gold 6148 processors, each fixed at 20 cores and 2.4 GHz base clock. There is no alternative core-count version of this specific CPU model; the 20-core count is the only configuration available for the 6148 in this system.

What does the 3.7 GHz turbo figure mean for actual workloads?

The 3.7 GHz turbo frequency is the maximum single-core boost speed. Under multi-threaded loads the processors will run at lower all-core frequencies, so sustained performance depends on the workload mix and thermal headroom inside the 2U chassis.

What does the 12 Gb/s SAS/SATA controller cap in practice?

The PERC H730P controller supports 12 Gb/s SAS and 6 Gb/s SATA links. With the installed 400 GB SATA SSDs the practical throughput ceiling is the SATA 6 Gb/s interface, while SAS drives or external enclosures can use the full 12 Gb/s bandwidth.
