The Precision T5810/T7810/T7910 Desktop & R7910 Rack Mount Workstations support memory speeds of 2133 MHz. System users have reported that with 2133 MHz memory installed, the system shows memory speed of 1866 or 1600 MHz.
Precision T5810, T7810 & T7910 Desktop & R7910 Rack Mount Workstations are configured with a processor from the Intel Xeon E5-1600 v3 or E5-2600 v3 product families. Though the chipset and memory slot on the motherboard support the 2133 MHz memory, not all of these processors support the higher memory speed of 2133 MHz. The computer system automatically reverts to the lowest memory speed of the two--memory and processor--when both do not support the same speed.
To achieve the maximum memory speed of 2133 MHz, both the memory and the corresponding processor that supports this speed must also be purchased or installed in the system. Reference the table below to verify which processors support the 2133 MHz memory:
| Intel Xeon Processor | Maximum memory speed supported |
|---|---|
| Intel Xeon E5-1603 v3 | 1866 MHz |
| Intel Xeon E5-1607 v3 | 1866 MHz |
| Intel Xeon E5-1620 v3 | 1866 MHz |
| Intel Xeon E5-1630 v3 | 1866 MHz |
| Intel Xeon E5-1650 v3 | 1866 MHz |
| Intel Xeon E5-1660 v3 | 1866 MHz |
