To simply describe, Cache memory is a temporary memory used by the processor of a computer. Processor uses this memory to temporary store software information or instruction data’s in order to process them faster. Every computer and laptops comes with cache memory, they are named as L1, L2 or latest L3 cache memory. The more cache memory your computer or laptop has the more software you can run at a time and faster they will run.
Now when you install operating system such as Windows XP, cache memory will only be 256 Kb by default where your actual memory is like 2-3 MB which means 2048 – 3072 Kb. So even though you have a good amount of space available in your cache memory but you have not been able to make use of that rather your computer seems slow. Through some very easy steps you can edit the registry to put the actual value and fix this issue to maximize your PC or laptop performance.
In Windows XP or Windows 7, Go to Start >> Run and type “regedit” and press OK. Registry Editor of your operating system will open.
Click the (+) sign besides the text “HKEY_LOCAL_MACHINE”.
