Mac Pro (Late 2013) ECC RDIMM kit

This 64GB kit contains two 32GB DDR3 1333MHz modules built as registered ECC RDIMMs for the Apple Mac Pro cylinder (MacPro6,1). The memory runs at 1.50V and uses major-brand chips on a 240-pin form factor. It is designed to match the system's required ECC registered specification.

Professionals expanding a cylinder Mac Pro

The kit suits editors, developers and scientists who need the maximum 64GB capacity for large datasets, virtual machines or multi-application workflows on MacPro6,1. Buyers with non-Apple workstations, laptops or desktop Macs that require unbuffered UDIMMs cannot use these registered modules. Systems limited to 16GB or 32GB per slot should also look elsewhere.

Registered ECC RDIMM architecture

The decisive specification is the registered ECC RDIMM design; only Mac Pro models that explicitly require registered error-correcting DDR3 1333MHz memory will accept this kit.

Perguntas sobre este artigo

How do I install the 240-pin RDIMM modules in the Mac Pro (Late 2013) and which step is often missed?

Power down, unplug, open the side panel, then push each 32GB module straight into a 240-pin slot until the ejector clips click; the step people miss is seating both clips fully so the ECC registered sticks register at 1333 MHz.

What maintenance or replacement will this 64GB DDR3 ECC kit need later?

No scheduled maintenance is required; if a 32GB module fails, replace the faulty stick with an identical DDR3 1333 MHz ECC RDIMM to keep quad-rank 4Rx4 operation intact.

What limit appears first when the Mac Pro runs sustained workloads with this memory?

The memory controller caps bandwidth at DDR3 1333 MHz PC3-10600, so throughput plateaus there before the 1.50 V registered DIMMs hit any thermal or power ceiling.
