Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rackmount server built for dense scale-out data centre computing. It ships with two Intel Xeon Platinum 8160 processors, each running at 2.1GHz with 24 cores and a 3.7GHz turbo frequency. The system includes 256GB of DDR4 2666MHz registered ECC memory across eight 32GB modules. Redundant 750W platinum power supplies and iDRAC9 Enterprise remote management come standard.

Suited For High-Thread Workloads

This configuration suits workloads that benefit from high core counts and large memory capacity, such as virtualisation hosts, database nodes or high-performance computing clusters. The eight 2.5-inch drive bays are populated with 300GB 10K SAS drives and the PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need more than eight internal drive bays or who require a different drive interface should evaluate other platforms.

24 DIMM Slots For Expansion

The motherboard provides 24 DDR4 DIMM slots with a maximum supported capacity of 3TB. Eight slots are occupied by the factory-installed 32GB modules, leaving sixteen slots available for future memory upgrades. This headroom lets the server grow with increasing dataset sizes or higher consolidation ratios without replacing existing memory.

Questions about this item

How often will the PERC H730P controller battery need replacement?

The PERC H730P includes a 2GB cache battery; plan to replace it every three to five years to maintain write-back caching during power loss.

What thermal limit appears first when both Xeon 8160 CPUs run at 3.7GHz turbo continuously?

The 1U chassis and 750W power supplies constrain sustained turbo; CPU package power and VRM temperatures hit their throttling points before memory or storage limits.

How loud are the fans when the server idles at 256GB DDR4 with both 750W PSUs active?

Idle fan speed stays low in a cooled rack; acoustic output rises sharply only when CPU load pushes the redundant power supplies past 50 percent utilisation.
