Crucial Registered DIMMs

Increase the performance of your servers

Buying new servers is expensive. Getting moreout of your current infrastructure isn’t.

Maximizing a server’s installed memory capacity with Crucial® RDIMMs is one of the easiest and most affordable ways to make your deployments faster and more efficient. Crucial RDIMMs contain a register chip, which directs data commands and helps control the flow of data within the server. By virtue of the register chip, Crucial RDIMMs have ECC parity, which helps prevent data errors and increases overall system reliability.

Speed up server applications

By installing Crucial RDIMMs, you’ll be able to maximize the performance capability of your CPUs and optimize your servers’ computing potential. Since memory typically functions as a fixed (non-shared) component, it’s often a bigger performance constraint than processors or storage drives, which can be shared. Maximize your investment in server infrastructure by maximizing memory capacity.

Get more out of your IT budget

At a fraction of the cost of new servers, Crucial RDIMMs allow youto extend the life and performance of your existing infrastructureand get more out of the rack space you already have. Even if youneed to replace existing deployments, you can still save by buyingservers with the least amount of preinstalled memory, then fullypopulating the installed memory capacity with Crucial RDIMMs.

Compatible with OEM servers and warranties1

Similar to how you can upgrade a server’s preinstalled componentsand choose whichever brands you want, you can do the samewith memory – without having to worry about voiding yourmanufacturer’s warranty. In terms of system compatibility, CrucialRDIMMs are optimized for the latest Intel® Xeon® processor productfamilies and 100% component and module tested.

Run more virtual machines and increase the responsiveness of virtualized applications

Since most of today’s enterprise applications are stored onservers and distributed to a number of virtual machines, theamount of installed server memory plays a more critical role thanever before. Every virtual machine running on a server typicallyrequires a dedicated amount of memory, meaning the morevirtual machines you’re running, the more memory you’ll need.

Available in the latest technology

Built with new technology tailored for the latest Intel platforms, Crucial DDR4 RDIMMs allow you to increase system performance with memory speeds up to 2666 MT/s and densities up to 32GB. Increasing the installed memory capacity of each server with modules equipped with 8Gb-based components enables your systems to reach their full performance potential – especially without rank limitations.
