How to Calculate Total Memory Size

Calculate your total memory size in kilobytes (KB) by adding the

DIMM memory size to the base memory size (64960 KB).

For example, if you installed a 32-MB DIMM into your computer

with 64-MB base memory, you should have about 96 MB.

Your computer might display memory size in kilobytes. For

example, 96 MB=97728 KB.

Note: 576 KB is reserved by the system.
