Dual 18-Core Xeon Blade Server

The Dell PowerEdge M640 is a half-height blade server built around two Intel Xeon Gold 6150 processors. Each CPU provides 18 cores running at a base frequency of 2.70 GHz with a maximum turbo of 3.7 GHz. The system ships with 128GB of DDR4 registered ECC memory across eight 16GB modules. It includes a Dell PERC S140 controller managing two 960GB SATA solid-state drives configured for RAID 0, 1, 5, or 10.

Virtualisation and Compute Targets

This blade suits organisations consolidating virtual machines, running private-cloud stacks, or executing high-performance compute jobs within a PowerEdge MX or M1000e chassis. The 10Gb dual-port network daughter card provides high-throughput connectivity for east-west traffic. Buyers who need GPU acceleration, local NVMe storage, or a standalone rack-mount form factor should evaluate other platforms.

Two-Socket LGA 3647 Maximum

The server supports a maximum of two processors in LGA 3647 sockets, and this unit already populates both sockets. Memory capacity can scale to 1.5TB using the 16 available DDR4 slots, but CPU count cannot increase beyond the installed pair. Verify that your chassis has an available half-height slot and compatible fabric before purchase.

Questions about this item

How do I verify the dual Xeon Gold 6150 processors and 128GB DDR4 are recognised after installation?

Open iDRAC9 Enterprise and check the hardware inventory; it will list both 18-core CPUs at 2.7GHz (3.7GHz Turbo) and show 128GB across the 16 DIMM slots.

What ships with the blade and what must I source separately?

The unit includes two Xeon Gold 6150 CPUs, 128GB DDR4 (8x 16GB), two 960GB SATA SSDs, PERC S140 controller, 57810S-K 10Gb dual-port daughter card and iDRAC9 Enterprise; front bezel, ready rails, chassis and operating system are not included.

Which memory configuration should I choose if I need room to grow beyond 128GB?

The 128GB ships as 8x 16GB DDR4 2666MHz registered ECC modules, leaving 8 of the 16 slots free for expansion up to the 2TB maximum.
