Dell PowerEdge XE9640 memory upgrade

This 32 GB DDR5 module is built for the Dell PowerEdge XE9640 rack server. It delivers ECC registered memory for workloads that require error correction and signal stability in a single 288-pin RDIMM.

Verify DDR5 RDIMM slot availability and rank limits

Before ordering confirm that your XE9640 has a free DDR5 RDIMM slot and that the memory controller supports 2Rx8 organisation at the target speed. The module runs at 1.1 V with a CAS latency of 40.

Adds 32 GB of registered ECC capacity per slot

Installing this module increases registered ECC memory without requiring unbuffered DIMMs or a different voltage. It fits the 288-pin DDR5 interface native to the platform and leaves other slots open for further expansion.
