Mac Pro 2013 memory kit

This 16GB kit contains four 4GB DDR3 ECC UDIMM modules built for the Mac Pro Late 2013 cylinder. It targets owners of model MacPro6,1 who need to populate all four slots with matched memory. The modules run at 1866 MHz with 1.50V unbuffered operation and carry major-brand chips for reliability.

ECC UDIMM compatibility

The single specification that decides fit is the ECC unbuffered UDIMM 240-pin form factor at DDR3 1866 speed. Apple’s Mac Pro Late 2013 requires registered ECC DIMMs, so unbuffered ECC UDIMMs will not be recognised by the firmware and the system will not boot. Buyers must verify their Mac accepts unbuffered ECC before ordering.

Suited for matched upgrades

This kit suits users replacing the factory memory with a full 16GB set of identical modules in a Mac Pro Late 2013 cylinder. It is not for builders who need registered ECC RDIMMs, which the platform requires, nor for anyone upgrading a different Mac model or a PC workstation that expects registered memory.

Questions about this item

What does the 1866 MHz DDR3 speed mean for a Mac Pro Late 2013?

The modules run at the 1866 MHz DDR3 rate the Mac Pro Late 2013 memory controller expects; they are PC3-14900 ECC UDIMM 240-pin DIMMs that match the system specification.

How does the ECC UDIMM 240-pin interface work in this Mac Pro?

The Mac Pro Late 2013 uses ECC unbuffered DDR3 on a 240-pin bus; these four 4 GB modules provide single-bit error correction without registered buffering.

Will the four 4 GB sticks physically fit the Mac Pro Late 2013 cylinder?

Yes, each module is a standard 240-pin ECC UDIMM with no heat spreader, matching the four user-accessible slots in the Mac Pro Late 2013 cylinder enclosure.
