SMART Modular Technologies’ DDR4 and DDR3 load-reduced dual in-line memory
modules (LRDIMMs) use a distributed buffer approach so that high-speed memory
controllers in CPUs can drive larger quantities of memory. There are also specific
configurations, such as when using three DIMMs per channel, that require LRDIMMs.
SMART Modular supports a wide lineup of DDR4 LRDIMMs ranging from 32GB
to 256GB. For OEMs requiring a range of LRDIMM density options, SMART
Modular can provide a smooth continuity of supply. SMART helps minimize
supply chain disruptions by self-qualifying new die revs and providing multi-
sourced DRAM options.
For OEMs with mission-critical requirements, SMART Modular offers Enterprise
Grade LRDIMMs to significantly minimize the risk of DRAM failures in deployed
systems. SMART Modular also offers a selection of Value Memory modules in its
LRDIMM series. Value Memory modules are cost-effective Tier 1 ODM JEDEC-
standard memory modules.
SMART Modular buys its finished lineup of commodity memory modules directly
from Tier 1 DRAM suppliers. These are the most commonly used modules for
standard server compute and storage applications
