Mac Pro DDR3 ECC kit

This 16 GB kit contains two 8 GB DDR3 1333 MHz ECC UDIMM modules built for Apple Mac Pro towers from Mid 2010 and Mid 2012. The 240-pin unbuffered design matches the factory memory slots in these systems. It targets owners of MacPro5,1 models who need to expand capacity with error-correcting memory.

Sustained workload stability

ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption in long rendering or compute sessions. The 1.50 V modules run at the standard PC3-10600 rate without overclocking, so thermal output remains consistent under load. Major-brand chips are tested for reliability across extended duty cycles.

16 GB capacity limit per kit

The kit delivers 16 GB total across two slots, which may not satisfy users who need higher densities for virtualization or large datasets. Builders requiring more memory must populate additional slots with compatible modules. Systems using non-ECC or registered DIMMs cannot use this kit.

Questions about this item

How much power does the 1.50 V DDR3 kit draw during continuous all-day operation?

Each module runs at 1.50 V, the standard voltage for DDR3 1333 ECC UDIMM, so power draw matches the JEDEC specification for that speed and voltage.

Does the Mac Pro (Mid 2010/2012) need any firmware update or special riser card to accept these 240-pin ECC UDIMMs?

The modules are built to the exact 240-pin ECC UDIMM form factor used by MacPro5,1; no extra riser or firmware step is required beyond the standard Apple memory-slot layout.

Can the 1333 MHz kit run in a Mac Pro that originally shipped with slower DDR3 speeds?

The memory will down-clock to the highest speed the system supports, so it works in Mac Pro models that shipped with lower DDR3 frequencies.
