Kit contents and fit

This kit provides 4GB of DDR3 memory as two 2GB unregistered ECC DIMMs built for the HP/Compaq Workstation Z600. It suits owners of that platform who need a matched pair to populate two of the three channels per CPU. The modules run at 1333 MHz with CL9 timing at 1.5V and use a 240-pin form factor. Buyers who need to fill all three channels per CPU or who require registered DIMMs should look elsewhere.

Installation notes

Each stick slots into a standard 240-pin DDR3 socket and the Z600 allows modules to be added one at a time. For best performance the supplier advises populating all three channels per processor to enable triple-channel interleaving. Mixing these unregistered ECC modules with registered ECC parts is not supported and will prevent the system from operating correctly.

Deciding specification

The memory is unregistered ECC DDR3 rated at 1333 MHz (PC3-10600) with a 1Rx8 organisation. This combination of speed, error correction and buffering type is the single factor that determines whether the kit will work in the target workstation.

Questions about this item

How can I verify the kit is running at DDR3 1333 with CL9 timing after installation?

Check the BIOS or a system-information tool such as CPU-Z; the memory should report 1333 MHz speed and 9-9-9 CAS latency at 1.5 V.

What exactly ships in the box and is anything else required to use it?

The package contains two 2 GB 240-pin DDR3 ECC unregistered DIMMs; no additional parts are needed for installation in a compatible HP Z600 workstation.

Should I choose the 4 GB (2×2 GB) kit or the 6 GB (3×2 GB) version for my Z600?

For triple-channel performance on a Z600, the 6 GB kit fills all three channels per CPU; the 4 GB kit occupies only two channels and leaves one empty.
