4GB DDR3-1600 DIMM for HP Z220 Workstations

This 4GB DDR3 module runs at 1600MHz with CL11 timings at 1.5V. It is built as a single-rank, unbuffered, non-ECC 240-pin DIMM. The kit targets owners of HP Compaq Workstation Z220 CMT or SFF systems using Intel Core i3, i5, i7, Pentium or Xeon processors on the C216 chipset.

Single-stick kit with lifetime exchange guarantee

The package contains one 4GB stick, allowing incremental upgrades without filling all four slots at once. Computer Memory Solutions validates each module against the listed Z220 part numbers and backs it with a limited lifetime warranty for exchange when purchased directly from them. No extra software, cables or heat spreaders are included.

Standard 240-pin DDR3 form factor for tool-free

The bare green PCB fits the Z220’s standard DIMM slots without clearance issues. Unbuffered, non-ECC operation matches the workstation’s consumer-grade memory controller. Maximum supported capacity is 32GB across four sockets, so this module leaves room for three more sticks if the workload grows.

Questions about this item

Will the 240-pin DDR3 DIMM need any firmware updates or periodic replacement to keep working in the Z220 workstation?

The module is a non-ECC, unbuffered DDR3 DIMM with no firmware; it runs at 1.5 V and CL11 timing and requires no scheduled replacement.

What limit appears first when the memory runs continuously at 1600 MHz in the HP Z220?

The workstation caps total memory at 32 GB across four sockets, so adding further modules hits that ceiling before speed or voltage limits are reached.

How much heat and power does the 4 GB stick draw during all-day operation?

Rated at 1.5 V with no heat spreader, the single-rank module draws minimal power and stays cool under sustained load in the Z220 chassis.
