Mac Pro Late 2013 Memory Kit

This 64GB kit contains four 16GB DDR3 1866 RDIMM modules built for the Mac Pro Late 2013 cylinder. It targets owners of MacPro6,1 systems who need ECC registered memory to reach the maximum supported capacity. The modules run at 1.50V and use major brand chips.

DDR3 1866 ECC RDIMM Limits

DDR3 1866 (PC3-14900) is the fastest DDR3 speed the Mac Pro Late 2013 officially supports. The registered ECC design adds a clock cycle of latency but provides error correction required for Xeon workstation stability. Four slots are available, so this kit fills the system completely.

Four-Module Installation

Install all four 240-pin RDIMMs into the Mac Pro's user-accessible memory tray; no tools are required beyond the latch. The modules have no heat spreaders, so they fit the tight clearance. Mixing these registered ECC sticks with unbuffered or non-ECC memory will prevent the system from booting.

商品問答

How do I know the 64GB kit with four 16GB modules is the right capacity for my Mac Pro Late 2013?

The kit matches the Mac Pro Cylinder (MacPro6,1) and fills all four slots with 16GB RDIMMs, giving the 64GB total that the system supports.

What does the DDR3 1866 speed mean for real workloads on this Mac Pro?

The modules run at 1866 MHz (PC3-14900) with ECC registered operation, so the Xeon CPUs listed — 3.7GHz E5-1620v2, 3.5GHz E5-1650v2, 3.0GHz E5-1680v2 or 2.7GHz E5-2697v2 — can access the full 64GB at the rated data rate.

Will the 240-pin RDIMM form factor and ECC registered design work in the Mac Pro Late 2013 memory slots?

Yes — the 240-pin DDR3 RDIMM is the exact form factor Apple specifies for the Mac Pro Cylinder, and the ECC registered design is required for the Xeon processors in that model.
