Server Buying Decisions: Memory

We reviewed several types of server memory back in August 2012. You still have the same three choices—LRDIMMs, RDIMMs and UDIMMs—but the situation has significantly changed now. The introduction of the Ivy Bridge EP is one of those changes. The latest Intel Xeon has better support for LRDIMMs and supports higher memory speeds (up to 1866 MHz). But the biggest change is that the pricing difference between LRDIMMs and RDIMMs has shrunk a lot, so it is time for an update.
