How much RAM you actually needHow to size memory from the pressure your machine is under now, why running short quietly costs speed, and when a matched pair beats one stick.RAM speed and latency, and when they matterWhat a kit's MT/s and CAS latency each measure, why true latency is the two together, and the machines where the numbers actually change anything.SO-DIMM vs DIMM: the memory a laptop takesWhy laptop memory is a different module from desktop memory, how DDR4 and DDR5 are keyed apart, and why some machines take no module at all.What is ECC memory, and when you need itWhat error-correcting memory actually catches, how registered and load-reduced modules differ from unbuffered ones, and why the platform decides.
