  • 5V operation suits registered DDR3 platforms

Capacity and fit

This kit delivers 12GB of DDR3 memory in three 4GB registered DIMMs built for the Dell PowerEdge R310. Each module runs at 1333MHz with CL9 timings and 1.5V operation. ECC and registered buffering protect data integrity in the server environment. The 240-pin form factor matches the system's six registered DIMM slots.

Sustained load behaviour

Under continuous operation the registered design reduces electrical load on the memory controller, helping stability during long compute runs. The modules automatically clock down to 1066MHz or 800MHz depending on the installed Xeon model and how many banks are populated. Quad-rank modules in the second bank drop to 800MHz while a third bank is disabled by chipset limits.

Upgrade context

The R310 supports up to 32GB of registered ECC memory across six slots, so this 12GB kit leaves room for further expansion. It replaces or adds to existing registered DIMMs but cannot be mixed with unbuffered ECC modules. Buyers needing more than 32GB total capacity or unbuffered memory support should look elsewhere.

Questions about this item

How much power does each 4 GB DDR3 1333 registered DIMM draw at its rated 1.5 V?

Each module runs at the standard DDR3 voltage of 1.5 V; total kit power depends on the server’s memory controller and how many ranks are active.

Does the Dell PowerEdge R310 need any specific BIOS setting or firmware version to recognise these 2Rx4 registered ECC sticks?

The R310 supports up to six registered ECC DIMMs; the modules will clock to 1066 MHz or 800 MHz automatically based on the installed Xeon X3400 or L3426 and bank population.

Can I keep my existing unbuffered ECC UDIMMs and add this registered kit to the same R310?

Mixing registered and unbuffered ECC modules is not supported in the R310; all six registered slots must use the same registered type.
