Cooling & Fans
Fan Cage 
View Fan Cage
The T640 has a Middle Internal fan cage that holds 4 Hot Swappable fans. These features must have the fans installed to be supported. NVMe/PCIe SSD and the 3.5"x 18 hard drives chassis
Rear Air Shroud 
View Air Shroud
The T640 comes with a main Air Shroud that has two large fans installed in the rear.
Rear GPU Fans 
View GPU Fans
The third and final Fan assembly is the 2 External fans. These external fans are only supported when GPUs are installed. These External fans sit Right on top of the PCIe slots.
If a GPU is installed you must add the GPU Air Shroud along with the normal Air Shroud.
On systems with eight fan configuration (Fan1, Fan2 are standard (STD) fans. Fan3-Fan6 are high-performance (HPR) fans. Fan7 and Fan8 are external Left and Right fans).
Memory
The PowerEdge T640 support memory speeds of 1866 MT/s, 2133 MT/s, 2400 MT/s, 2666 MT/s, and 2933 MT/s depending on the DIMM types installed and configured. All memory on all processors and channels run at the same speed and voltage. By default, highest common supported speed between the CPUs and DIMMs. The operating speed of the memory is also determined by the maximum speed supported by the processor, the speed settings in the BIOS, and the operating voltage of the system.
NVDIMM Not Supported on the Following:
- 16 + 8 drive configuration
- 32 drive configuration
When installing the NVDIMM the battery will be placed under the ODD slot on the front of the server.

Power Supply Units (PSU)
The Dell EMC PowerEdge T640 system supports up to two AC or DC redundant power supply units (PSUs). If two PSUs are used, they must be of the same maximum output power.
When two identical PSUs are installed, power supply redundancy (1+1 – with redundancy or 2+0 – without redundancy) is configured in the system BIOS.
Your system supports the hot spare feature that significantly reduces the power overhead associated with power supply unit (PSU) redundancy.
