HP Z840 Workstation specifications
Processor
technology
Intel Series C612 chipset:
●
Support for the Intel Xeon Processor E5-2600 Series, including processors up to 150 W
●
Integrated 4-channel memory controller
●
Microarchitecture improvements
●
Large L3 cache for superior performance
●
Intel QuickPath Interconnect (QPI) connects processors and I/O controller with speeds up to 9.6 GT/s
Power supply
●
850 W Silver, 88% efficient, wide-ranging, active Power Factor Correction, single auxiliary dongle on a
12V rail, ERP 0.5W, Built-in-Self Test (BIST)
●
1125 W Gold, 90% efficient, wide-ranging, active Power Factor Correction, three auxiliary dongles on
three separate 12V rails, ERP 0.5W, Built-in-Self Test (BIST)
●
China’s Energy Conservation Program (CECP) configurations
●
European Union ErP LOT6 2013 power limit of 0.5 W in off mode
Memory
technology
●
Dual in-line memory modules (DIMMs) based on DDR4 2133MHz technology
●
Error checking and correcting (ECC)-protected
●
Eight direct-attach memory channels (four per processor) enable low-latency access and fast data
transfer for improved performance
●
Configurations with one processor have eight DIMM slots; a second processor adds eight more DIMM
slots
●
With one processor, up to 1 TB system memory (128 GB DIMMs)
●
With second processor, up to 2 TB system memory (128 GB DIMMs)
●
2133 MHz 4, 8, 16 GB ECC Registered DIMM
●
2133 MHz 32, 64, 128 GB ECC Load Reducing DIMM
NOTE: Do not install memory modules into memory slots if corresponding processor is not installed.
Only Registered and LR ECC DIMMs are supported.
Do not mix any of the different types RDIMM [Registered] and LR DIMM [Load Reduction]) of memory. The
system will not boot and will produce a memory error.
For maximum performance, on workstations with two processors, install the same number of DIMMs per
processor and install them in pairs of the same size.
Distribute DIMMs across all memory channels for optimal performance.
Do not install memory modules into memory slots if corresponding processor is not installed.

●
Eight SAS ports (6 GB/s)
●
Two ports (6.0 GB/s) available for optional eSATA. eSATA capable with optional dual eSATA bulkhead
kit.
