Server-grade DDR3 memory kit

This 64GB kit contains four 16GB DDR3 registered ECC DIMMs rated at 1333MHz with CL9 timings. The modules operate at 1.5V and use a 2Rx4 organisation on a 240-pin interface. They are built specifically for ASUS Z9 server boards including the Z9PA-D8, Z9PA-D8C and Z9PA-U8 models.

Suited for capacity upgrades on supported Z9

IT teams expanding memory on compatible ASUS Z9 servers will find the registered ECC design matches the platform requirements. The kit is not for desktop or consumer motherboards that accept only unbuffered non-ECC memory, nor for systems limited to lower densities or different DDR generations.

Quad-channel population rule governs installation

The ASUS Z9 platform requires modules to be installed in groups of four for quad-channel operation, which this 4x16GB kit satisfies exactly. Mixing registered DIMMs with unbuffered or load-reduced types is not supported, so the full kit must populate a matched set of slots.

Questions about this item

Does the 64GB kit ship with four 16GB DDR3 modules or are any sticks missing?

The package content lists three memory RAM sticks, so one 16GB module is not included and must be purchased separately to reach the advertised 64GB total.

The title says 1333 MHz but the description also mentions 1600 MHz — which speed will the modules actually run at?

The specification sheet rates the kit at DDR3 1333 (PC3 10600) with CL9 timing; the 1600 MHz figure appears only in the descriptive text and is not the guaranteed operating speed.

Will the registered ECC DIMMs work at the full 1333 MHz on an ASUS Z9PA-D8 board with a Xeon E5-2600 v2 processor?

The board supports up to 1866 MHz with certain Xeon E5-2600 v2 CPUs, so the 1333 MHz registered ECC modules will run at their rated speed without downclocking.
