Dell PowerEdge R640 1U dual Xeon server

The Dell PowerEdge R640 is a 1U rack server equipped with two Intel Xeon Bronze 3106 processors running at 1.7GHz. It ships with 64GB of DDR4 memory across 24 DIMM slots and includes a PERC H730 RAID controller supporting RAID 0, 1, 5, 6, 10, 50, and 60. Eight 2.5-inch hot-plug drive bays provide internal storage capacity.

Suited for virtualization and database workloads

This server fits businesses running file storage, virtualization, databases, backups, or application hosting where dual-socket compute and redundant 750W power supplies are required. It is not suited for buyers needing GPU acceleration, larger 3.5-inch drive bays, or configurations exceeding the installed 64GB memory limit.

Memory fixed at 64GB DDR4 maximum

The system supports a maximum of 64GB DDR4 across 24 slots, so the installed capacity cannot be expanded beyond what is already populated. This ceiling determines whether the platform can meet your workload's memory footprint.

Questions about this item

What memory modules can be added later and how many slots are free?

The system has 24 DDR4 DIMM slots, 12 per processor, supporting 4GB to 128GB modules up to 2666MT/s; speed depends on the installed Xeon Bronze 3106 capability.

Which component reaches its ceiling first during continuous heavy workloads?

The two Xeon Bronze 3106 processors run at a fixed 1.7GHz with eight cores each, so CPU throughput is the first limit under sustained load.

How loud and hot does the 1U chassis get with both 750W supplies running 24/7?

Dual 750W redundant supplies and eight 2.5-inch drive bays mean continuous fan airflow; the 1U form factor concentrates heat, so expect noticeable noise and warm exhaust.
