4GB DDR2 Registered DIMM Kit

This 4 GB kit contains two 2 GB registered DIMMs built for DDR2 400 (PC2-3200) servers. It targets administrators maintaining legacy Supermicro X6Da3-G2, X6Da8-G2 or X6Dae-G2 systems that require registered memory.

Registered Dual-Rank Architecture

Each module is a 240-pin DDR2 SDRAM stick operating at 1.8 V with CL3 3-3-3 timing and a dual-rank 2Rx4 organisation. The registered buffer is the single specification that determines compatibility; only boards designed for registered DIMMs will accept this kit.

Two-Stick Matched Pair

The package supplies two matched sticks so the required pair-population rule for these Supermicro boards is satisfied immediately. No heat spreaders, cables or software are included, keeping the upgrade focused on memory capacity alone.

Questions sur cet article

What does the DDR2 400 speed rating mean once the modules are installed in a Supermicro X6Da3-G2?

The modules will run at 400 MHz with CL3 timing, delivering PC2-3200 bandwidth as specified for this platform.

How does the registered DDR2 interface affect what the memory controller can address?

Registered DIMMs buffer the address and command signals, allowing the chipset to support up to eight ranks across the eight sockets.

What physical slot and module dimensions are required for these 240-pin DIMMs?

Each stick uses the standard 240-pin DDR2 DIMM form factor and fits the eight registered DIMM sockets on the listed Supermicro boards.
