When you're not actively using your computer, background tasks - including automatic backup and antivirus software scans - take this opportunity to run when they will least disturb you. Although too many carbohydrates might slow you down after lunch, your computer slows down for different reasons. You may have experienced sluggish behavior after booting your machine, after performing a fast user switch, or even after lunch. In previous versions of Windows, system responsiveness could be uneven. They even have a fancy marketing name for it- SuperFetch: It's running a low-priority background task that harvests previously accessed data from the disk and plops it into unused system memory. Vista is trying its darndest to pre-emptively populate every byte of system memory with what it thinks I might need next. Those figures explain why I only have 6 megabytes of "free" memory in Windows Vista. In summary, here's how much faster each cache memory type in your computer is than the hard drive:

Otherwise you're going straight to the hard drive, mister, and if you have to ask how much going to the hard drive will cost you in performance, you can't afford it.ĭiomidis Spinellis published an excellent breakdown of the cache performance ratios in a typical PC circa January 2006: The primary mission in the life of every cache is to populate itself as quickly as possible with the data that's most likely to be needed- and to consistently deliver a high "hit rate" of needed data retrieved from the cache. It's expensive, high-speed memory sucking down power for zero benefit. Just like the level 1 and level 2 cache on your CPU, system memory is yet another type of high-speed cache that sits between your computer and the disk drive.Īnd the most important rule of cache design is that empty cache memory is wasted cache memory. You have to stop thinking of system memory as a resource and start thinking of it as a a cache. What about the other 2,046 megabytes of system memory? But that's maybe a couple megabytes, at most. So Notepad clearly needs a little memory for itself: enough to execute, and to store the contents of the text document it's displaying.

But, unlike most Windows machines, it’s nearly impossible to upgrade the RAM in Apple computers.
It’s much easier to see how much RAM is in your Mac.

How to Check How Much RAM You Have on Mac Just boot it up, use the keyboard shortcut to enter its BIOS or UEFI firmware (it’s different on each PC), and look for information about the system’s memory or RAM. This is particularly helpful if you’re using a PC without a working operating system. This information is generally displayed in your system’s UEFI firmware or BIOS, too. If you build your own PC, your RAM may not run at its advertised timing until you tweak the timings. RELATED: How Does RAM Speed and Timing Affect My PC's Performance?

Download and install CPU-Z, launch it, and click the “Memory” tab to see this information. To see more specific information about your RAM timings on any version of Windows, we recommend CPU-Z. You can also quickly open this by opening your Start menu, right-clicking “Computer,” and selecting “Properties.” Look to the right of “Installed Memory” under System. Instead, you can see your total amount of RAM on the Control Panel > System and Security > System page. The Task Manager doesn’t offer this useful information on Windows 7.
