    With the introduction of 8Gb DRAMs, Load-Reduced DIMMs (LRDIMMs) now outperform Registered DIMMs (RDIMMs) by offering both higher memory capacity and bandwidth. This paper demonstrates how 32GB 2Rx4 LRDIMMs based on 8Gb DDR4 DRAMs provide a superior solution for enterprise servers requiring deep memory and fast data access.

A white paper authored by IDT (acquired by Renesas) and Micron details research into memory and bandwidth for today's high-performance servers. LRDIMMS and RDIMMS traditionally have been seen as complementary, with the former targeting applications requiring deeper memory and the latter for applications requiring higher bandwidth. 

The introduction of 8-gigabit DRAMS has resulted in a growing number of Internet applications benefiting from both deeper memories and higher bandwidth. This paper shows how 32 GB 2RX4 LRDIMMs transcend similar RDIMMs to meet the needs of today’s data center enterprise servers, by providing an optimal combination of deeper memory and higher data bandwidth, even at mainstream module densities.
