4 Things to Know About Registered vs. Unbuffered RAM

You won’t notice the latency difference Registered RAM adds one extra clock cycle of latency, but that’s measured in nanoseconds. Your CPU waits on storage, network, or user input far more than RAM latency.

Your board likely supports both Many server motherboards, like the Supermicro X11SSH-F, auto-configure for either type. If you find a deal on registered modules, go for it.

Capacity and bandwidth matter more For almost any real workload, memory bandwidth and total capacity outweigh the tiny latency penalty. Buy the cheap RAM.

Registered RAM uses slightly more power The difference is negligible on a server board that already sips power. You won’t notice it.
