32GB DDR3 ECC RDIMM Kit

This 32GB kit contains four 8GB DDR3 1866 registered ECC modules built for the Mac Pro Late 2013 cylinder. The 240-pin RDIMMs run at 1.50V and use major-brand chips qualified for Apple order numbers ME253LL/A, MD878LL/A, MQGG2LL/A and BTO/CTO configurations.

Suits Mac Pro 6.1 owners needing 32GB

Buyers with a Mac Pro 6,1 who want a matched 32GB set of registered ECC memory will install this kit directly. Systems that require unbuffered UDIMMs, non-ECC modules, a different DDR generation or a capacity other than 32GB cannot use these sticks.

DDR3 1866 Registered ECC

The decisive specification is the DDR3 1866 registered ECC RDIMM form factor, which matches the Mac Pro Late 2013 memory controller. Only Macs that accept this exact module type and speed will recognise the full 32GB capacity.

Perguntas sobre este artigo

Will the registered ECC RDIMM modules need any firmware updates or periodic replacement?

The modules are hardware components with no firmware to update and no scheduled replacement interval; they remain in service until a module fails.

What sustained-use limit appears first — thermal throttling or memory bandwidth saturation?

Without heat spreaders the chips rely on case airflow, so thermal limits will appear before the DDR3-1866 bandwidth ceiling is reached.

How much extra heat and power do the four 1.50 V RDIMMs add when the Mac Pro runs all day?

Each module draws 1.50 V at DDR3-1866 speeds; total added heat equals the combined power draw of the four registered DIMMs under continuous load.
