商品問答

What comes in the box and does the Mac Pro need any extra parts to install these modules?

The kit includes twelve 64GB LRDIMM modules for a total of 768GB. No extra parts are required; the modules install directly into the Mac Pro memory slots.

Should I choose the 2666MHz or 2667MHz version for my Mac Pro 2019?

Both speed ratings refer to the same PC4-21300 modules; the Mac Pro 2019 will run them at 2666MHz automatically.

What does the 2666MHz rating mean once the memory is installed in the Mac Pro?

The memory operates at DDR4 2666MHz (PC4-21300) with ECC load-reduced technology, giving the Xeon W-3223 processor 768GB of registered capacity for large workloads.
