Dense dual-socket 1U server for scale-out compute

The Dell PowerEdge R640 packs two Intel Xeon Gold 6142 processors with 16 cores each at 2.6 GHz and 256 GB of DDR4 ECC memory into a single rack unit. It targets organisations running virtualisation clusters, high-density databases or HPC workloads that need maximum core count per rack space. Buyers needing GPU acceleration or single-thread frequency above 3.7 GHz turbo should look elsewhere.

Verify rack depth power

Confirm your cabinet accommodates a 1U chassis with ready rails and that dual 750 W platinum supplies match your PDU connectors. The C620 chipset offers 24 DIMM slots; eight are occupied by 32 GB modules leaving room to reach the 3 TB maximum. Network connectivity uses an X520/I350 daughter card providing two 1 GbE and two 10 Gb SFP+ ports — ensure your top-of-rack switches have matching transceivers.

PERC H730P RAID battery iDRAC Enterprise

The H730P 2 GB controller supports RAID 0 1 5 6 10 50 60 plus pass-through with a battery-backed cache for write protection. Eight 2.4 TB 10K SAS drives ship installed delivering raw capacity for local datasets. iDRAC 9 Enterprise enables full remote power console and firmware management without an OS. No SSDs or additional drive carriers are included.

Questions about this item

What comes in the box and what must I buy separately?

The server ships with two Xeon Gold 6142 processors, 256 GB DDR4 memory, eight 2.4 TB SAS hard drives, the PERC H730P controller, the X520/I350 quad-port network card, iDRAC9 Enterprise, two 750 W power supplies, rails and a front bezel. No extra parts are included.

Which memory configuration should I choose for this system?

The unit already contains 256 GB across eight 32 GB DDR4 2666 MHz registered ECC modules. All 24 slots are populated to this level, leaving 16 slots free for expansion up to the 3 TB maximum.

What does the 2.6 GHz base clock mean when the server is under load?

Each Xeon Gold 6142 runs at 2.6 GHz base frequency and can boost to 3.7 GHz with Turbo, giving 16 cores per processor a higher throughput during demanding workloads.
