Computer Memory Solutions CM2567210600ECCNRDIMM1R8 4GB (2x2GB) DDR3 1333 ECC Unregistered DIMM

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.
