RAM is often blamed first for abrupt slowdowns and overall sluggish PC performance. In both gaming and productivity workloads, a lack of free system memory can cause these symptoms, but increasing capacity isn’t always the surefire way to fix them. In fact, modern systems running out of memory to the point of significant performance loss isn’t as common as you think. Configuration plays a big part in your RAM’s ability to do its job, and sometimes, the best upgrade can be as easy as a toggle in your BIOS.
