Overview

WIDE RANGE OF FREQUENCIES,
EASY TO INSTALL

Memory frequency, also known as RAM speed, refers to the clock speed of the memory module (measured in megahertz or MHz). RAM doesn’t process data, it just transfers it between the other components (like the CPU, GPU, and storage) so the higher the frequency, the more data the RAM can transfer between these components. Which frequency you choose usually depends upon the RAM speed supported by your CPU and motherboard.

Acer UD100 range of desktop DRAM modules provides a wide variety of frequency options. Choose your frequency from 2400 up to 3200 MHz and each module easily installs in the memory slot to add the frequency you need to speed up your system.

QUALITY COMPONENTS, AND QUALITY ASSURANCE
UD100 is built with a selection of high-quality components (s
uch as gold-plated contacts) to ensure excellent performance and reliability. These components are additionally subjected to rigorous testing at several points in the production process.

CERTIFIED COMPATIBILITY,
INTEL AND AMD PLATFORMS

Supporting the latest Intel and AMD platforms, UD100 memory modules are compatible with the latest motherboards from major manufacturers.

OPTIMAL POWER CONSUMPTION, STABLE PERFORMANCE
The standard memory voltage (VDimm) of 1.2 V keeps energy consumption low and ensures a stable system performance.
