48GB ECC DDR3 kit for Xserve

This 48GB kit contains twelve 4GB DDR3 1066 ECC UDIMM modules built for the Apple Xserve (Early 2009, 8-Core). It targets administrators who need the maximum supported memory capacity in these servers for virtualization, database caching or heavy multitasking workloads.

Replaces smaller DDR3 kits

The kit replaces any lower-capacity DDR3 1066 ECC UDIMM configuration currently installed in the Xserve. The jump is worth it when the server shows memory pressure under load, when adding virtual machines, or when the existing modules cannot fill all twelve slots with matched 4GB sticks.

Verify twelve-slot Xserve configuration

Confirm the system is the Early 2009 8-Core Xserve (model identifier Xserve3,1, order numbers BTO/CTO) with twelve available DIMM slots. Check that the installed processors are 2.26GHz Xeon E5520, 2.66GHz Xeon X5550 or 2.93GHz Xeon X5570, and that the board accepts unbuffered ECC UDIMMs at 1.50V.

Questions about this item

Will these 240-pin DDR3 ECC UDIMM modules fit the memory slots in an Apple Xserve (Early 2009, 8-Core) with model ID Xserve3,1?

Yes, the kit is built specifically for the Xserve3,1 (A1279, EMC 2279) and uses the 240-pin DDR3 ECC UDIMM form factor that the server requires.

What is the correct way to populate all 12 slots with these 2Rx8 modules, and which step do installers most often miss?

Fill every slot with one 4 GB module; the step most often missed is ensuring each module clicks fully into the 240-pin socket so the ECC circuitry engages.

If a module fails years from now, what replacement does the lifetime warranty cover?

The lifetime warranty covers a direct replacement with an identical 4 GB DDR3 1066/1067 MHz ECC UDIMM module from the same kit specification.
