HP Z220 DDR3 1600 Kit

This 8 GB kit contains two 4 GB DDR3-1600 DIMMs validated for HP and Compaq Workstation Z220 CMT and SFF systems. It targets owners of those workstations who need a straightforward memory upgrade without compatibility guesswork. The modules are unbuffered, non-ECC and run at the standard 1.5 V.

8 GB Dual-Channel Capacity

Two ranks of 4 GB each populate two of the four available slots and provide 8 GB total, leaving room to reach the platform maximum of 32 GB if more memory is added later. The CL11 11-11-11 timings deliver standard DDR3-1600 bandwidth for everyday workloads. Applications that demand more than 8 GB or require ECC protection will exceed what this kit supplies.

Two Matched DIMMs Included

The package supplies exactly two 240-pin DIMMs from a major-brand chipset, pre-tested as a matched pair to simplify dual-channel installation. No heat spreaders, cables or software utilities are bundled. Buyers who need a single module, a 16 GB kit or modules with ECC will have to choose a different configuration.

Questions about this item

Will the 240-pin DDR3 1600 CL11 modules run without voltage changes on my Z220 CMT with an Intel Core i5?

Yes, the kit runs at the standard 1.5 V and matches the Z220 CMT specification, so the system will detect the 8 GB automatically at DDR3-1600.

How can I confirm the kit is operating at CL11 11-11-11 timings after installation?

Open Task Manager or CPU-Z on Windows, or run dmidecode on Linux, and verify the reported speed shows 1600 MHz with CAS latency 11.

The box lists two 4 GB sticks — are any brackets, screws or thermal pads also included?

Only the two 240-pin DIMMs are supplied; no brackets, screws or thermal pads are in the package.
