Apacer Technology Inc. U-DIMM Memory Modules

U-DIMM (Unbuffered DIMM) is a JEDEC-compliant design applicable for desktop computers, industrial computers, and embedded systems. Manufactured with the highest quality original DRAM chips, stringently tested for quality assurance, and verified for compatibility, Apacer U-DIMMs are high-performance memory modules that are highly stable and compatible.

VLP U-DIMM (Very Low Profile Unbuffered DIMM) is a JEDEC-compliant design that measures only 0.72-inch in height, making it ideal for space-constraint systems, such as small-size industrial computers and embedded systems. Using VLP U-DIMM not only prevents mechanical issues, but the space saved may be used to improve heat dissipation, save energy, cut down business costs and improve system stability.

ECC U-DIMM (ECC Unbuffered DIMM) is a JEDEC-compliant module designed specifically for servers and workstations that require a highly stable operation. Manufactured with the highest quality original DRAM chips, it supports the ECC function to detect and correct data errors. These also have a built-in temperature-monitoring thermal sensor to prevent overheating and improve the memory module’s reliability.

VLP Mini ECC U-DIMM is a JEDEC-compliant design characterized by its small size, high performance, and high stability. Measuring only 82mm long and 18.8mm high, its compact size is especially applicable for space-constraint networking, communication, server, and embedded systems. It also supports ECC function to detect and correct data errors and a built-in temperature-monitoring thermal sensor to prevent overheating and improve the memory module’s reliability.

Anti-Sulfuration U-DIMM memory modules are mainly used in equipment exposed in a highly contaminated environment. This includes automobile, military, medical, transport, networking, and outdoor electronic products, and electronic equipment used in areas of high-concentration sulfur gas, e.g. volcanoes, hot springs, and mines. Airborne sulfur-containing particles can easily react with silver used in the electrode to form silver sulfide, which is non-conductive. As sulfuration increases, the resistance value increases, eventually causing an open circuit. To solve the problem of resistor sulfuration, Apacer has developed the world’s first anti-sulfuration memory module for use in a sulfur-rich environment, and this innovative design is now patented.
