System-Specific DDR3 Kit

This 32GB kit contains four 8GB DDR3-1600 ECC unregistered DIMMs built for the HP Z420 workstation. Each module runs at CL11 with 1.5V across 240 pins. The set is validated for that platform and ships as a matched 4-piece kit.

ECC Unregistered Design

The memory uses ECC unregistered (unbuffered) DIMMs in a 2Rx8 configuration. Error correction protects data integrity while the unregistered layout matches the Z420’s supported topology. No heat spreaders are fitted and chip brands may vary.

Capacity Limits and Speed Steps

The Z420 accepts up to 32GB with a 400W chassis or 64GB with a 600W chassis across eight sockets. Depending on the installed processor the kit will operate at 1066, 1333, 1600 or 1866 MHz; 1866 MHz requires an E5-2600 v2 or E5-1600 v2 CPU.

Questions sur cet article

Will the 1600 MHz speed run at full rate in my Z420 workstation?

The Z420 runs memory at 1866, 1600, 1333 or 1066 MHz depending on the processor installed. E5-2600 v2 or E5-1600 v2 CPUs are required for 1866 MHz; otherwise the kit will operate at 1600 MHz or the next lower supported speed.

Does the 240-pin DDR3 DIMM fit every Z420 memory slot?

Yes. The kit uses standard 240-pin DDR3 unregistered DIMMs, which match the Z420's eight DIMM sockets. Each module is a 2Rx8 8 GB stick, so four modules occupy four of the eight slots.

What clearance do the modules need inside the Z420 chassis?

The sticks have no heat spreader, keeping them at the standard low-profile DDR3 height. They fit the Z420's DIMM sockets without interfering with CPU coolers or the 400 W or 600 W power-supply chassis.
