Transcend has released its new 32 GB Load-Reduced DIMMs which uses a buffer to reduce the load on the system's memory bus. This allows the system to increase the storage capacity and performance whilst still reducing the system's power consumption.
Standard RDIMM technology has the system's memory bus lead directly to the DRAM chips, with no buffer in between which increases the actual electrical load on the memory bus and consequently limits the memory speeds. Transcend's LRDIMM's buffer acts as a middle man between the memory controller and the DRAM memory, and thus reduces the electrical load on the system memory bus and make it possible to offer much larger storage capacities without compromising performance.
Transcends 32 GB DDR3 LRDIMMs, make it possible to have up to 768 GB of system memory on a motherboard with 24 memory slots. This is a 50 percent increase when compared to RDIMMs, and a 500 percent jump over UDIMMs, which offered 512 GB and 128 GB respectively on a motherboard with 24 memory slots.
Given the exponential growth of memory technology, perhaps it won't be too long before we see systems offering 16 Exabytes (16 x 1018 bytes or 16 million TB), the maximum theoretical limit for 64-bit systems.
The DIMMs are backed by Transcends limited lifetime warranty, with no word on pricing yet.
