5 Reasons 16GB RAM Is Worth It for an Older Office PC

8GB is the bottleneck, not the CPU An i5-2400 is still fine for office work, but running out of RAM forces the system to use the page file, which slows everything down.

Browsers eat 4–6GB alone Chrome or Edge with a dozen tabs can consume that much. Add Word, Excel, and a PDF reader, and 8GB gets tight fast.

You’ll notice stuttering and lag When RAM runs out, switching tabs or opening documents causes delays. The whole machine feels sluggish.

The upgrade is cheap and easy Used DDR3 sticks cost a few bucks on eBay. Just check that your motherboard has two free slots and match speeds if possible.

It’s the best performance-per-dollar upgrade Doubling to 16GB gives you headroom for heavy multitasking. If you regularly have dozens of tabs and multiple Office apps open, this is worth it.
