HP Z820 Workstation specifications

	Intel® Series C602 chipset with:
	● Support for the Intel® Xeon™ Processor E5-2600 Series, including processors up to 150W
	● Integrated 4-channel memory controller
Processor	●	Microarchitecture improvements
technology	●	Large L3 cache for superior performance
	● Intel QuickPath Interconnect (QPI) connects processors and I/O controller with speeds up to 8.0
		GT/s
	NOTE: HP Liquid Cooling option is available for all Z820 processors.
	● 850W Silver, 88% efficient, wide-ranging, active Power Factor Correction, two auxiliary dongles
		on two separate 12V rail, ERP 0.5W, Built-in-Self Test (BIST)
Power supply	● 1125W 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 0.5W in off mode
	● Dual in-line memory modules (DIMMs) based on DDR3 1600MHz technology
	● Error checking and correcting (ECC)-protected
	● Eight direct-attach memory channels (four per CPU) enable low-latency access and fast data
		transfer for improved performance
	● Configurations with one CPU have eight DIMM slots; a second CPU adds eight more DIMM slots
	● With one processor, up to 256 GB system memory (32 GB DIMMs)
Memory	● With second processor, up to 512 GB system memory (32 GB DIMMs)
	●	1600 MHz 2, 4 GB ECC unbuffered DIMM
technology

● 1600 MHz 4, 8, 16 GB ECC registered DIMM

● 1333 MHz 32 GB ECC Load Reducing DIMM (available second half of 2012)

NOTE: Do not mix any of the different types (unbuffered, registered, and load reducing DIMMs) of memory. The system will not boot and will produce a memory error.

NOTE: For maximum performance, on workstations with two CPUs, install the same number of

DIMMs per CPU and install them in pairs of the same size

NOTE: Distribute DIMMs across all memory channels for optimal performance

● PCIe Gen3 (PCIe3) bus speeds; can support three PCIe Gen3 graphics cards in PCIe3 x16 slots

Graphics cards ● Up to one 160W or two 75W graphics cards with 850W power supply

●Up to two 300W or three 225W graphics cards with optional 1125W power supply (other configuration restrictions may be required)
