DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6142 2.6GHz 16-Core 768GB DDR4 8x 800GB SSD H730P

Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rackmount server fitted with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. It arrives with 768 GB of DDR4 registered ECC memory across 24 slots and eight 800 GB SATA SSDs managed by a PERC H730P controller with 2 GB cache. Dual 750 W redundant power supplies, iDRAC9 Enterprise remote management, quad-port networking and sliding rails complete the package.

Scale-Out Compute Target

This configuration suits dense scale-out workloads such as virtualisation clusters, database nodes or high-performance computing where core count and memory capacity matter more than local storage expansion. Eight 2.5-inch bays and the SAS/SATA backplane limit internal drive count, so buyers who need more than eight internal drives or GPU acceleration should look elsewhere. The fixed 1U height also rules out full-length add-in cards.

Memory Capacity Decides Fit

The single specification that decides fit is the installed 768 GB of DDR4 memory. With 24 DIMM slots populated by 32 GB modules, the system reaches three-quarters of its 3 TB maximum, leaving little room for further memory growth without replacing existing modules. If the workload demands more than 768 GB from day one, a different memory configuration or a higher-capacity chassis is required.
