System-Specific ECC Kit

This 32 GB kit contains two 16 GB DDR3-1333 registered DIMMs built for the HP Workstation Z800. ECC error correction and registered buffering make it suitable for workstation and server workloads that require data integrity. It is not compatible with standard desktop motherboards or unbuffered memory configurations.

Registered ECC Requirement

The modules are 240-pin DDR3 RDIMMs with CL9 latency at 1.5 V, organised as dual-rank 2Rx4 parts. Your Z800 must support registered ECC memory; mixing these with unbuffered DIMMs will prevent the system from booting. Verify the workstation manual before installation.

Thermal and Power Profile

Operating at the standard 1.5 V DDR3 voltage, the sticks draw typical registered-DIMM power without a heat spreader. In a properly ventilated Z800 chassis they run at normal DDR3 thermals and produce no audible noise. The kit adds 32 GB of capacity within the platform’s original power envelope.

Questions about this item

Will the 1333 MHz speed run at full rate in a Z800?

Yes, the DDR3 1333 modules match the Z800 native memory bus and will operate at their rated 1333 MHz without down-clocking.

Does the 240-pin registered ECC design limit mixing with other memory?

These are 240-pin DDR3 ECC registered DIMMs; they cannot be mixed with unbuffered or non-ECC modules and require a workstation or server platform that supports registered memory.

What physical clearance do the 16 GB sticks need inside the Z800?

Each 16 GB module is a standard-height 240-pin DDR3 RDIMM with no heat spreader, so it fits the Z800 DIMM slots without extra clearance.
