HP Z230 memory upgrade

This 2GB DDR3 1600 CL11 module is built for the HP Workstation Z230. It installs in a 240-pin UDIMM slot and runs at 1.5V without ECC. The single-rank 1Rx8 design meets JEDEC PC3-12800 specification for a direct warranty-safe upgrade.

Suits single-slot Z230 expansion

Ideal for administrators adding one stick to an empty slot in a Z230 workstation. Not for systems that require ECC registered memory or higher-density modules. Builders needing more than 2GB per slot or quad-channel kits should look elsewhere.

2GB DDR3 1600 CL11 1Rx8 spec

Capacity, speed, latency, rank and voltage together decide if this module matches the Z230 memory controller. Verify the platform accepts non-ECC unbuffered DDR3 at PC3-12800 before purchase.

Questions about this item

Does the box contain only the 2GB DDR3 1600 CL11 240-pin 1.5V Non-ECC UDIMM module, or are any tools or cables also included?

The package contains the single 2GB DDR3 1600 PC3-12800 CL11 1Rx8 240-pin 1.5V Non-ECC Unbuffered DIMM module. No tools, cables or additional components are supplied.

Should I choose the 2GB DDR3 1600 CL11 1Rx8 module or look for a different capacity or rank for the HP Z230?

This part is a single 2GB 1Rx8 module rated DDR3 1600 CL11 at 1.5V. Select it when you need a 2GB increment; choose a higher-capacity or dual-rank module only if your configuration requires more memory per slot.

What does the PC3-12800 1600MHz CL11 rating mean once the module is installed in the HP Z230 workstation?

The module will run at DDR3 1600 with CAS latency 11 at 1.5V, delivering PC3-12800 bandwidth. The HP Z230 memory controller will configure these timings automatically on boot.
