The Mac Pro (Late 2013) has four memory slots that you can upgrade with up to 64GB of memory using 1866 MHz DDR3 ECC compliant memory DIMMs. To ensure compatibility, Apple recommends that you use Apple-approved memory. You can purchase Apple-approved memory online from the Apple Store or by visiting an Apple Retail store or Apple Authorized.
- PC3-10600E, 1333 MHz, DDR3 SDRAM UDIMMs; Error-correcting code (ECC) 72-bit wide, 240-pin ECC modules; 36 ICs maximum per ECC UDIMM; The Mac Pro can accept slower memory. It just run slower. The Mac Pro can accept faster memory, the DIMM will be automatically downclock to match the CPU / logicboard's max possible speed.

Requirements
_DDR3_1333_SODIMM-638324-images1800jpg-1.jpg "Mac")
When you upgrade the memory in your Mac Pro (Late 2013) it must meet these requirements.
- 1866 MHz DDR3 full length DIMM. Mixing memory speeds is not recommended.
- Error-correcting code (ECC).
- 4GB, 8GB, or 16 GB DIMMs.
- Unbuffered (UDIMM) or Registered (RDIMM). Do not mix UDIMMs and RDIMMs.
- 240 pin DIMM.
- 1.5 or 1.35 volts.
- Use the same size memory modules across all slots to maximize performance.
- DIMMs with heatsinks are not supported and may damage the DIMM mechanism.
Important: All DIMMs must be 1866MHz DDR3 ECC compliant. The Mac Pro supports both unbuffered UDIMMs and registered RDIMMs, but it is important not to mix these two types of memory. Mixing UDIMMs and RDIMMs will result in a memory error tone when you turn on your computer.
