Server Memory Kit

This 8GB kit contains two 4GB DDR3 registered DIMMs built for the Dell PowerEdge R310 running Xeon X3400 or L3426 processors. It delivers ECC error correction and registered buffering for stable operation in a server environment.

Registered ECC Requirement

The modules are 240-pin DDR3-1333 CL9 parts that only work in systems accepting registered ECC memory; unbuffered ECC or non-ECC DIMMs are not supported on this platform.

Six-Slot Configuration

The R310 provides six registered DIMM slots with a 32GB maximum, so this pair leaves four slots open for future expansion while the memory controller clocks the kit to 1333, 1066 or 800 MHz depending on CPU and population.

Questions about this item

What does the 1333 MHz rating mean once the modules are installed in a Dell PowerEdge R310?

The modules run at 1333 MHz with compatible Xeon X3400 or L3426 processors, but automatically clock down to 1066 MHz or 800 MHz depending on the specific CPU and how many banks are populated.

How does the DDR3 240-pin registered interface affect usable speed in this server?

Registered DIMMs are required; mixing with unbuffered ECC is not supported. Quad-rank modules in the first dual-channel bank run at 1066 MHz, while adding them in the second bank drops speed to 800 MHz.

What physical slot requirements must the R310 meet for this 2 x 4 GB kit?

The server needs two free 240-pin DDR3 DIMM slots. The R310 provides six registered DIMM sockets, so this pair fits without exceeding the 32 GB registered maximum.
