SK hynix VLP ECC UDIMMs (Very Low Profile Double Data Rate Synchronous DRAM Unbuffered Dual In-Line Memory Modules) are low power, high-speed operation memory modules. These VLP ECC UDIMMs are intended for use as main memory when installed in systems such as embedded systems, micro-servers and workstations.
VLP ECC UDIMMs are running at 544/667/800/933 MHz clock speed and offering 8500/10600/12800/14900 MB/s bandwidth on the primary data bus.
