High-quality, JEDEC-compatible server DRAM with less hassle

The Micron Design ID (DID) Agnostic Server DRAM approach fixes most of the problems with stock-outs, declined orders and delayed deliveries to make it easier for our partners to do business. DID agnostic server DRAM streamlines procurement and makes it hassle free. This approach builds off JEDEC compatibility among server modules, where one DID module will often work just as well as a module built with a slightly different silicon technology series. Partners and resellers who do not care about the server DRAM DID can easily get the memory capacities, configurations and speeds they need from available inventory. The DID agnostic server DRAM SKUs allow Micron to substitute and ship high-quality, in-stock compatible server memory. By simplifying inventory management and delivering better supply availability, Micron helps improve our partners’ businesses. 

For Micron partners who perform quals and track specific design IDs (or silicon technology series) of Micron memory, the ordering process and manufacturer part numbers (MPNs) don’t change. Those partners continue to purchase DID specific server DRAM. For the other partners and their reseller customers, Micron has reintroduced DID agnostic server DRAM SKUs. This approach significantly trims the number of server MPNs and keeps the MPNs consistent even when new design IDs and revisions are introduced to make procurement simpler and orders easier and faster to fulfill.

Micron Server DRAM increases performance and helps maximize IT budgets.

Speed up applications and get more out of your IT budget with Micron Server DRAM.  Maximizing installed memory capacity with Micron Server DRAM is one of the easiest and most affordable ways to make your deployments faster and more efficient. 

Speed up server applications

By installing Micron Server DRAM, 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. Boost 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, Micron DRAM enables you to extend the life and performance of your existing infrastructure and get more out of the systems you already own. Even if you need to replace existing servers, you can still save money by buying new servers with the least amount of pre-installed memory, then upgrade to the maximum memory capacity with Micron Server DRAM. 

Run more virtual machines and increase the responsiveness of virtualized applications
Since most of today’s enterprise applications are stored on servers and distributed to many virtual machines, the amount of installed server memory plays a more critical role than ever before. Every virtual machine running on a server typically requires a dedicated amount of memory, meaning the more virtual machines you’re running, the more memory you’ll need.
