Server memory kit

This 32GB kit contains four 8GB DDR3 1066MHz ECC Registered DIMMs built for the Dell PowerEdge T310. Each module runs at 1.5V with CL7 timing and a 4Rx8 quad-rank organisation. The 240-pin design matches the server's registered memory slots exactly.

For single-socket Xeon 3400 upgrades

Suited for administrators expanding a PowerEdge T310 that uses a Xeon 3400 series processor and requires registered ECC memory. Not for systems that only accept unbuffered ECC modules, nor for platforms limited to single or dual-rank DIMMs. Mixing registered and unbuffered ECC is not supported by this server.

32GB maximum with quad-rank modules

The kit fills all four quad-rank slots supported by the T310, delivering the full 32GB registered ECC capacity. Population rules limit the first dual-channel bank to 1066MHz; adding modules to the second bank drops speed to 800MHz, and a third bank is disabled. DDR3-1333 modules automatically clock down to match these constraints.

Questions about this item

Does my Dell PowerEdge T310 need a Xeon 3400-series processor for this registered ECC memory to work?

Yes, the T310 requires an Intel Xeon 3400-series processor to support registered ECC RDIMMs; Celeron, Pentium and Core i CPUs only accept unbuffered ECC memory.

Will all four 8 GB quad-rank modules run at 1066 MHz in my T310?

The first two modules in the primary dual-channel bank run at 1066 MHz; adding the second pair in the next bank drops that bank to 800 MHz, and a third bank would be disabled.

How can I verify the kit is operating at the correct speeds after installation?

Check the BIOS memory configuration or a system utility such as CPU-Z; the first bank should report 1066 MHz and the second bank 800 MHz for quad-rank modules.
