Virtium’s DDR4 Memory Modules

Virtium’s DDR4 memory modules provide high durability and capacity in small ultra-lowprofile (ULP) Mini-UDIMM form-factor. Featuring the PC4-2400 interface, these new memory modules dramatically enhance embedded systems through their footprint, capacity and performance.

Designers of embedded systems seek the optimal blend of attributes in the memory they choose, but often have had to compromise in order to meet their system size, durability and/or cost objectives. Fortunately, these requirements can be filled with Virtium’s industry-leading DDR4 memory modules. Target applications for Virtium’s DDR4 ULP Mini-UDIMM modules include blade servers, 1U rack designs, single-board computers, mezzanine cards, and a range of designs with space constraints. Virtium’s ULP memory modules are 17.78mm, compared to standard low-profile modules’ 18.75mm. Virtium’s DDR4 memory modules deliver the highest performance PC4-2400 solutions, longest product availability, and lower cost of ownership over time. As with all Virtium DDR products, these DDR4 memory modules solutions deliver significant power savings, in addition to bandwidth twice that of DDR3.

About Virtium

Virtium is a leading supplier of industrial-grade solid-state storage and memory solutions for the world’s top OEMs. For nearly two decades, it has designed and built its products in the USA, fortified by a global network of sales and support locations. Virtium’s world-class technology and unsurpassed customer support result in superior industrial embedded solutions for our interconnected world.

Engineers can look to Virtium’s high density Mini-UDIMM 16GB DDR4 Memory Modules for consistent performance under rugged conditions. Their PC4-2400 interface ensures fast data transfer and long product availability, which equates to a lower cost of ownership over time. Virtium DDR4 products offer bandwidth twice that of the DDR3 family with significant power savings and support ECC detection and correction for applications that demand high-performance and accuracy. With low power auto self-refresh capability and an operating range from -40C to 125C, these solutions keep working longer.


Virtium’s Mini-UDIMM design comes in a 17.78mm form factor, smaller even than the low-profile standard of 18.75mm. High-performance and long life in a compact design make it ideal for blade servers, SBCs, mezzanine cards and other applications that require powerful and durable memory in designs that have tight space-constraints.
