System-specific DDR3 ECC kit

Computer Memory Solutions supplies a 12 GB kit built from three 4 GB unregistered ECC DIMMs. Each module runs at DDR3-1333 with CL9 timings at 1.5 V. The 240-pin sticks are validated for HP Z200, Z210, Z400, Z600 and Z800 workstations.

Triple-channel population

The workstations use three memory channels per CPU, so the three-module kit fills one bank for interleaved bandwidth. Modules may be added one at a time, but peak throughput needs all three channels populated. DDR3-1333 parts automatically clock down to 1066 MHz or 800 MHz depending on the installed Xeon model and total module count.

Buyers restoring or expanding compatible HP

Shops upgrading supported Z-series systems with ECC unregistered memory will find the kit a direct fit. Builds that require registered DIMMs, capacities beyond 48 GB with two CPUs, or non-ECC consumer modules should look elsewhere.

Domande su questo articolo

Will the 1333 MHz speed hold under sustained load?

The modules are rated DDR3-1333 (PC3-10600) with CL9 timing at 1.5 V. The system automatically clocks them down to 1066 MHz or 800 MHz depending on the Xeon model and number of modules installed.

How much heat and power should I expect from three 4 GB sticks running all day?

Each stick runs at 1.5 V without a heat spreader. Total capacity is 12 GB across three unregistered ECC DIMMs; power draw and thermals follow standard DDR3-1333 unbuffered specifications.

Which workstation must I already own for this kit to work?

The kit is guaranteed compatible with HP Workstation Z200, Z210, Z400, Z600 or Z800. Z600 systems require a C2-revision Intel 5520 chipset board for registered DIMMs, but these modules are unregistered ECC.
