Server purpose and target users

This Dell PowerEdge R640 rack server ships with a single Xeon Gold 6226R processor running at 2.9 GHz and 256 GB of DDR4 ECC registered memory. It is built for organisations that need a dense 1U platform for virtualisation, database workloads or general compute and want to choose their own storage drives.

Who should consider it and who should not

It suits buyers who want a tested chassis with a PERC H740P RAID controller, dual 750 W power supplies and iDRAC9 Enterprise remote management already installed. It is not for buyers who require a second processor from day one, those who need GPU acceleration, or teams that must populate every 3.5 inch drive bay with drives included in the purchase.

The specification that decides fit

The chassis provides four 3.5 inch drive bays with SATA connectivity and a maximum memory capacity of 7.68 TB across the DDR4 slots, so the number of bays and the memory ceiling are the key limits to verify against your workload.

Questions about this item

How many DDR4 DIMM slots remain open for future memory expansion beyond the installed 256GB?

The system ships with 256 GB across 16 DDR4 modules and supports up to 7.68 TB, leaving additional slots available for further upgrades.

Which component reaches its ceiling first when the Xeon Gold 6226R runs at full load continuously?

The 16-core Xeon Gold 6226R at 2.9 GHz with 22 MB cache will hit its thermal and frequency limits before the PERC H740P RAID controller or dual 750 W supplies become bottlenecks.

What noise and heat output should I expect from the dual 750 W power supplies and cooling fans during 24/7 operation?

Dual 750 W supplies and chassis fans in the 36 x 24 x 10 in rack chassis produce enterprise-grade acoustic and thermal levels typical for a 1U server under sustained load.
