Dual Xeon Gold 6136 virtualisation server

The Dell PowerEdge R640 is a 1U rackmount system equipped with two Intel Xeon Gold 6136 processors running at 3.00GHz. Together they provide 24 cores and 256GB of DDR4 ECC registered memory. A PERC H740P RAID controller and ten hot-swap 2.5-inch drive trays are included for storage configuration.

Suited to memory-heavy multi-tenant workloads

This configuration targets virtual desktop infrastructure, database clusters and high-transaction application hosting where core count and memory throughput matter. Organisations needing GPU acceleration, single-thread frequency above 3.00GHz or capacities beyond the 3TB DDR4 ceiling should evaluate alternative platforms.

256GB DDR4 ECC registered memory installed

The system ships with 256GB of DDR4 ECC registered RAM across its memory slots, supporting expansion up to 3TB total capacity. This baseline fits many virtualisation clusters, and additional modules can be added to match specific workload density requirements.

Questions about this item

How do I add more DDR4 memory beyond the 256GB installed?

The server supports up to 3TB of DDR4 ECC Registered memory across its DIMM slots, so additional modules can be installed as workloads grow.

Which component reaches its ceiling first during continuous heavy compute?

The two Xeon Gold 6136 processors provide 24 cores total at 3.0GHz base clock; sustained all-core turbo will hit thermal and power limits before memory bandwidth saturates.

What noise and heat should I expect when the R640 runs 24/7 in a rack?

Dual 12-core CPUs and the H740P controller draw significant power, so the chassis fans ramp up under load, producing noticeable airflow noise and exhaust heat typical for 1U density.
