64 GB DDR4 ECC Registered kit for HP Z840
This 64 GB kit contains two 32 GB DDR4 2400 MHz registered DIMMs with ECC and a CL17 timing. It is built for the HP Compaq Workstation Z840 and runs at 1.2 V on major-brand chipsets. The modules are unbuffered by a heat spreader and use a 2Rx4 organisation.
Upgrade from non-ECC or lower-capacity DDR4
The Z840 supports up to 512 GB of registered ECC RDIMMs across 16 slots when two CPUs are installed. Adding this kit increases capacity while keeping the registered ECC topology the platform requires. If the installed processor only supports 1866 MHz the memory will clock down automatically to match the CPU capability.
Tool-free DIMM installation with channel rules
Installation is a simple press into the 288-pin slots, but the Z840 uses white DIMM slots to mark the first slot of each channel. For one DIMM per channel populate only the white slots. Mixing registered and unbuffered modules or filling slots in the wrong order will prevent the system from posting.

이 상품에 대한 질문
Does the 288-pin DDR4 DIMM fit the white DIMM slots on the HP Z840 workstation?
Yes, the 288-pin DDR4 DIMMs are designed for the Z840's registered DIMM slots; the white slots mark the first DIMM per channel for single-DIMM-per-channel population.
What is the correct way to install the two 32 GB modules so the Z840 runs them at 2400 MHz?
Install one module per channel in the white slots first; if an 1866 MHz processor is fitted the memory will clock down to 1866 MHz regardless of the 2400 MHz rating.
When would the registered ECC modules need to be replaced in a Z840 running at the 512 GB maximum?
Replace modules only if memory diagnostics report correctable ECC errors rising above threshold or if a future CPU upgrade requires a different speed grade.
