HP Z230 memory upgrade

This 4 GB DDR3 1600 module is built specifically for the HP Workstation Z230. It uses a 240-pin UDIMM form factor and runs at 1.5 V with CL11 latency. The single stick adds 4 GB of non-ECC capacity to compatible systems.

Straightforward desktop installation

The unbuffered DIMM fits into a standard 240-pin slot without tools. Align the notch, press until the latches click, and the system recognises the memory on boot. Problems only appear if the slot is dusty or the module is not fully seated.

Suits Z230 owners needing a small capacity boost

Builders who want more than 4 GB per slot or who require ECC registered memory should look at other options. This module is limited to the specific HP platform and DDR3 generation.

Questions about this item

How can I verify the module is running at DDR3 1600 CL11 after installation?

Check the memory speed and CAS latency in the BIOS or with a tool like CPU-Z; the module should report 1600 MHz and CL11 timings when seated correctly in the HP Z230.

What comes in the box and do I need any extra parts for the HP Z230?

The package contains one 4 GB 240-pin DDR3 UDIMM (part 1U6D32R804GB); no additional cables, brackets or heat spreaders are required for the Z230.

Which capacity version should I choose for a balanced upgrade on the Z230?

This 4 GB DDR3 1600 CL11 2Rx8 module is the only capacity offered in this listing; add one or more identical sticks to reach the Z230's maximum supported memory.
