16GB ECC DDR3 kit for HP Z420

This 16GB kit contains two 8GB DDR3-1600 ECC unregistered DIMMs built for the HP Compaq Workstation Z420. The modules run at 1.5V with CL11 timing and use major-brand chips. They are designed for server or workstation workloads that require error-correcting memory in a 240-pin form factor.

Capacity scales to 32GB or 64GB

The Z420 accepts up to 32GB with a 400W chassis or 64GB with a 600W chassis across eight sockets. This 16GB kit fills two slots and leaves room for expansion. Depending on the processor installed, the system may clock the memory at 1866MHz, 1600MHz, 1333MHz or 1066MHz.

ECC unregistered 240-pin DDR3

The decisive specification is ECC non-registered DDR3 in a 240-pin DIMM. Registered or fully buffered modules will not work in this platform. Buyers who need registered ECC or a different DDR generation must choose another product.

Questions about this item

Will the 1600 MHz DDR3 ECC unregistered DIMMs run at full speed if I keep my existing 1333 MHz modules in the Z420?

The Z420 runs all installed memory at the speed supported by the processor and the slowest module present, so adding 1333 MHz sticks will force the 1600 MHz kit down to 1333 MHz.

How can I verify the kit is running at 1600 MHz with CL11 timing after installation?

Check the memory speed and CAS latency in the system BIOS or with a tool such as CPU-Z; they should report 1600 MHz and 11-11-11 timings when the processor supports that speed.

Does the package include only the two 8 GB sticks or are any installation tools or cables supplied?

The box contains the two 8 GB DDR3 ECC unregistered DIMMs and nothing else; no tools, cables or brackets are included.
