Dual-socket 1U server with 768GB DDR4

This Dell PowerEdge R640 chassis fits four 3.5-inch SATA drives and ships with two Xeon Silver 4214 processors running at 2.2GHz. A PERC H740P RAID controller and iDRAC9 Enterprise licence are installed, and the system includes dual 750W power supplies. The unit is new and has been fully updated to the latest firmware before shipment.

Ideal for memory-intensive virtualisation

The 768GB DDR4 ECC registered memory and twelve cores per processor suit applications that need large in-memory datasets and high thread counts. Four 3.5-inch bays provide local storage capacity for SATA hard drives. Buyers who need GPU compute, more than four drive bays, or a lower memory starting point should consider other configurations.

768GB DDR4 ECC registered memory installed

This is the single specification that determines whether the server matches the workload. The memory is fully populated across both processors and operates at DDR4 speeds with ECC protection. No drives are included, so storage must be added separately to complete the build.

Questions about this item

How do the two Xeon Silver 4214 processors fit into the R640, and what installation step is often missed?

Both processors seat in the dual-socket board; the step often missed is aligning the notches before locking the retention lever so the 12-core chips seat evenly.

Which components in this 768 GB DDR4 configuration will need replacement first?

The DDR4 ECC registered modules and the two 750 W power supplies are the parts most likely to require replacement after extended service.

What limit appears first when the PERC H740P controller drives four 3.5-inch SATA bays under sustained load?

The four-bay 3.5-inch SATA backplane and the H740P's 8-lane PCIe link become the throughput bottleneck before the 10 GbE 562T adapter saturates.
