Mac Pro 2019 512GB DDR4 Kit

This 512GB kit contains eight 64GB DDR4 2933 ECC registered DIMMs built for the 2019 Mac Pro tower and rack models. It targets professionals running 12, 16, 24 or 28-core Xeon W processors who need maximum memory capacity for large datasets and heavy multitasking. The modules operate at 1.20V with 2Rx4 organisation.

Verify MacPro7,1 and slot count

Confirm your system reports MacPro7,1 and that all eight DIMM slots are free before ordering. The kit matches Apple order numbers BTO/CTO and model IDs A2304 (EMC 3413) or A1991 (EMC 3203). It is not for earlier Mac Pro generations, iMac Pro or any non-Apple workstation.

288-pin RDIMM build with major-brand chips

Each module uses a 288-pin registered form factor with major-brand chipsets and undergoes strict validation for reliability. The registered design adds electrical buffering for signal integrity across all eight slots. Install in matched sets to maintain quad-channel performance and ECC error correction.
