Memory
The PowerEdge T140 supports up to 4 DDR4 DIMMs. The T140 is designed to support the socket H4, Intel® Xeon® processor
E-2100 product family CPU, which has 2 memory channels per CPU, with each channel supporting up to 2 DIMMs.
The maximum system population at launch will be 64GB. The minimum system population is one 8GB DIMM.
Supported memory
The PowerEdge T140 supports memory with the following features:
•
Unbuffer (UDIMM) ECC DDR4 technology
•
Each channel carries 64 data and 8 ECC bits
•
Up to 64 GB of UDIMM memory (4 x 16GB UDIMM)
•
Up to 2666 MT/s DIMMs
•
Flexible Memory Configuration
•
ODT (On Die Termination)
•
Clock gating (CKE) to conserve power when DIMMs are not accessed
•
DIMMs enter a low power self-refresh mode
•
I²C access to SPD EEPROM for access to thermal sensors
•
Memory Optimized (Independent Channel) Mode
•
100% Single Bit Error Correction
•
Memory Off-lining is NOT supported.
Memory speed
The PowerEdge T140 supports 2666MT/s DDR4 memory. This system will run all memory on all CPUs and channels at the same
speed and voltage. By default the system will run at the highest speed for the lowest voltage of the worst case channel DIMM
configuration.
The operating speed of the system is determined by:
•
Supported speed of DIMMs
•
DIMM configuration on any channel
•
Max speed supported by the CPU
•
Speed request by user in BIOS setup screen
The operating voltage of the system is determined by:
•
Voltages supported by the DIMMs which is 1.2V.
•
Voltages supported by the platform.
