32GB DDR3 ECC kit for Mac Pro 2013

This 32GB kit contains four 8GB DDR3 1866 ECC UDIMM modules built for the Apple Mac Pro Late 2013 cylinder. It runs at 1.50V with unbuffered error-correcting memory and 240-pin form factor. The modules use major-brand chips and are tested for compatibility with MacPro6,1 systems.

Suits owners of Mac Pro Late 2013 needing ECC memory

Buyers with any other Mac model or non-Apple desktop should look elsewhere because the pin-out and firmware are specific to the 2013 cylinder Mac Pro. Systems requiring registered or load-reduced DIMMs cannot use this unbuffered kit. Builders wanting speeds above 1866MHz must choose a different specification.

1866MHz DDR3 ECC UDIMM speed decides fit

The memory operates at DDR3 1866 (PC3-14900) with ECC unbuffered signalling. This exact speed and protocol are required by the Mac Pro Late 2013 memory controller. If your system demands a different DDR generation, voltage or registered topology, this kit will not function.

Questions about this item

Will the ECC UDIMM modules need any periodic replacement or maintenance once installed in the Mac Pro Late 2013?

The DDR3 ECC UDIMM modules have no moving parts and require no scheduled maintenance or replacement under normal operation in the Mac Pro Late 2013.

What limit appears first when the 32GB kit runs sustained workloads on the Xeon E5-1650v2 or E5-1680v2 processors?

The memory controller on the Xeon E5-1650v2 and E5-1680v2 tops out at DDR3 1866, so bandwidth ceiling is reached before capacity or thermal limits.

How much heat and power do the four 8GB unbuffered ECC DIMMs add when the Mac Pro runs all day?

Each module runs at 1.50V without a heat spreader; total draw is modest and the Mac Pro Late 2013 thermal design handles the load quietly.
