64GB DDR4 Registered ECC Module

This 64GB DDR4 module operates at 2933 MT/s with CL21 latency and 1.20V voltage. It uses a 288-pin DIMM form factor and features a 2Rx4 rank organisation. The registered buffer and ECC functionality are designed for server platforms that require error correction and signal stability.

Suited for Registered ECC Slots Only

This module fits systems that accept registered ECC DDR4 memory. It will not function in platforms that require unbuffered non-ECC modules or that cannot address 64GB per slot. Buyers needing standard desktop memory should look elsewhere.

Registered ECC With 2Rx4 Organisation

The registered buffer and ECC parity bits combined with the 2Rx4 rank structure determine compatibility with qualified server motherboards. Verify that your platform supports registered ECC DDR4 at this density and rank configuration before purchase.
