Picking the right server memory is mostly about three things: ECC, type and capacity. This quick guide from Serverwale keeps it simple.
Server RAM uses ECC (Error-Correcting Code) to catch and fix memory errors automatically — essential for 24x7 reliability in databases, virtualization and storage. Desktop (non-ECC) RAM is not a substitute for production servers.
RDIMM (Registered) is the common choice for most builds up to ~512GB. LRDIMM (Load-Reduced) enables the highest capacities (1TB+) on platforms with many DIMM slots, at a small latency cost. Match the type your server officially supports.
Refurbished DDR4 ECC is one of the best-value upgrades in India — tested modules at a fraction of new pricing. You can buy refurbished servers pre-configured with the RAM you need, or contact Serverwale to spec a build. Learn more about Serverwale and our 72-point testing.
