DDR5 DIMM Socket Status and DDR4 Spec Comparison

DDR5 DIMM Socket Status

JEDEC began initial DDR5 socket standard (also called DDR5 connector) in 2018, and delivered several proposed versions based on global socket makers' performance in 2019 and 2020. JEDEC works with partners (e.g. Intel) to conduct socket performance tests, including high-temperature warpage (similar to 3D X-ray soldering ability test based on IPC-A-610 standard) and signal integrity (SI) tests. The results of these performance tests are sent to all global socket makers, as the basis of product improvement and industrial comparison. The results also open to share with electronics brands and ODM/OEM/EMS companies, using as the accountable 3rd party reference.
