2U rack server with dual 20-core Xeon Gold 6148 CPUs, 64 GB DDR4 ECC memory, PERC H730P RAID controller, eight 2.4 TB 10K SAS drives, quad-port 1/10 GbE networking.
The Dell PowerEdge R740 is a 2U rack server built for compute-intensive workloads. It ships with two Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The system includes 64 GB of DDR4 registered ECC memory across four 16 GB modules and a PERC H730P RAID controller with 2 GB cache. Eight 2.4 TB 10K SAS drives provide high-capacity storage in the 2.5-inch drive bays.
This configuration suits environments that need high core counts and redundant power in a 2U form factor. The dual 750 W platinum power supplies and iDRAC9 Enterprise remote management support continuous operation. Buyers who need more than 24 DIMM slots, a different drive interface or a higher single-thread clock speed should evaluate alternative platforms. The maximum memory capacity of 3 TB allows future expansion within the existing chassis.
The installed CPUs deliver 40 total cores at a base frequency of 2.4 GHz, defining the server's parallel processing capability. Turbo Boost reaches 3.7 GHz for burst performance on lighter threads. This clock speed and core count determine whether the system matches the licensing and throughput requirements of the target application. Memory runs at 2666 MHz DDR4 across 24 available slots.

Other versions of this model
Same family, different memory, cooler or clock — compare before you commit.
This unit is the 8-bay 2.5" 2U model; it holds exactly eight 2.5" SAS drives and the installed set is eight 2.4TB 10K drives.
Each of the two 20-core Xeon Gold 6148 processors runs at 2.4 GHz base and can turbo to 3.7 GHz, giving 40 cores total for parallel workloads.
The PERC H730P 2GB controller supports 12 Gb/s SAS/SATA; the eight 2.4TB 10K SAS drives operate at that 12 Gb/s link speed.
