UDIMM

Unbuffered DIMMs are the ideal module for high-speed, low-cost computing systems. Our UDIMMs come in SDRAM, DDR, DDR2, and DDR3 solutions and offer data rates as high as 1333 MT/s, and provide parity and ECC capability. They’re an industry standard in high-volume production, offering a great balance of price and performance.

Our DDR2-1066 and DDR3-1333 memory boasts some of the fastest data rates in the business—easily meeting industry demand for increased speeds and improved bandwidth. And because of our manufacturing efficiencies, the DDR2 and DDR3 UDIMMs we build offer some of the most compelling value in the industry today.
