OWC 8GB DDR4 2666 MHz R-DIMM Memory Upgrade Module

Key Features 8GB Capacity 2666 MHz Clock Speed PC4-21300 288-Pin R-DIMM Low Noise 8-Layer PCB Voltage: 1.2V 19-19-19-14.25 Timings ECC Error Correction, Registered 1024M x 72 Chip Architecture RoHS CompliantBoost your supported Mac Pro's performance with the 8GB DDR4 2666 MHz R-DIMM Memory Upgrade Module from OWC / Other World Computing. Delivering speeds up to 2666 MHz, this module is a memory upgrade designed to improve your computer's start-up times, overall responsiveness, and ability to handle data-intensive applications. ECC (Error-correcting code) technology enables the module to detect and correct the most common kinds of internal data corruption. The module is registered, features a CAS latency of 19 and a power rating of 1.2V, and works on systems with a 288-pin DIMM slot and a DDR4-enabled chip. Note: Do not mix R-DIMMs and LR-DIMMs. Mixing R-DIMMs and LR-DIMMs will result in a memory error flash of the status indicator light when you turn on the Mac Pro.
