Dell PowerEdge R640 4LFF Server
This Dell PowerEdge R640 server ships in a 4LFF chassis with a single Intel Xeon Gold 6126 processor running at 2.6GHz and 128GB of DDR4 ECC registered memory. A PERC H740P RAID controller and a 10Gb dual-port 562T network adapter are installed. The unit includes two 750W power supplies and iDRAC9 Enterprise remote management.
Suited for memory-intensive workloads
This configuration fits buyers who need large DDR4 capacity and 10Gb networking in a 1U rack form factor with four 3.5-inch drive bays. It is not for buyers who require a second processor installed, pre-populated storage drives, GPU acceleration, or a different drive bay count or form factor.
Deciding spec: four 3.5-inch drive bays
The chassis provides exactly four 3.5-inch bays wired for SATA drives through the PERC H740P controller. If your deployment needs more bays, a 2.5-inch bay layout, or a different drive interface, this server will not match the requirement.

Questions about this item
Will the 128GB DDR4 memory need expansion beyond the 24 slots to reach the 7.68TB maximum?
The R640 supports up to 7.68TB across 24 DDR4 slots; 128GB uses only a fraction of that capacity.
Does the single Xeon Gold 6126 at 2.6GHz become the bottleneck before the second CPU socket is filled?
With one 12-core 6126 installed, the second socket remains empty, so compute limits appear before the dual-socket ceiling.
How loud and hot do the dual 750W supplies and 10GbE adapter run during 24/7 operation?
Dual 750W units and the 562T 10GbE adapter are cooled by the chassis fans; noise and heat scale with total load.
