Targeted server upgrade

This 32 GB kit contains four 8 GB DDR3-1333 registered ECC DIMMs built for the IBM System x3200 M3 models 7327 and 7328. Each module runs at 1.5 V with CL9 timing and a quad-rank 4Rx8 organisation. The 240-pin form factor matches the server’s six DIMM sockets exactly.

Suited for memory expansion only

Administrators who need to reach the 32 GB registered-ECC ceiling on these two Xeon-based systems will find a validated, matched set here. The kit is not for workstations, desktops or any platform that requires unbuffered memory, non-ECC modules, a different DDR generation or a higher clock speed.

Quad-rank density constraint

The processor’s memory controller supports a maximum of four quad-rank registered DIMMs; installing this full 4 x 8 GB kit occupies that limit and the firmware will reduce the operating frequency to 800 MHz. Buyers who need the modules to run at the rated 1333 MHz must populate fewer quad-rank sticks.

Questions about this item

How do I install the four 8 GB DDR3 1333 ECC registered quad-rank DIMMs in the IBM System x3200 M3, and what step is often missed?

Populate the six DIMM sockets with the four modules following the two-per-bank rule; the step often missed is that the processor automatically clocks the quad-rank DIMMs down to 800 MHz when two are installed in the same bank.

What maintenance or replacement will the 32 GB DDR3 1333 ECC registered quad-rank kit need later?

No periodic maintenance is required; replacement is only needed if a module fails, at which point the limited lifetime warranty from Computer Memory Solutions covers a direct exchange.

What limit appears first when the 32 GB DDR3 1333 ECC registered quad-rank kit runs under sustained load in the x3200 M3?

The chipset forces the quad-rank modules to run at 800 MHz instead of the rated 1333 MHz once two modules share a memory bank, reducing sustained bandwidth.
