    A system with 512 MB of RAM (the minimum requirement for Windows Vista) can see significant gains from ReadyBoost. [14] [15] In one test case, adding 1 GB of ReadyBoost memory sped up an operation from 11.7 seconds to 2 seconds. However, increasing the physical memory (RAM) from 512 MB to 1 GB (without ReadyBoost) reduced it to 0.8 seconds. [16]

    1 GB PC3200 non-ECC modules are usually made with 16 512 Mbit chips, 8 on each side (512 Mbits × 16 chips) / (8 bits (per byte)) = 1,024 MB. The individual chips making up a 1 GB memory module are usually organized as 2 26 8-bit words, commonly expressed as 64M×8. Memory manufactured in this way is low-density RAM and is usually compatible ...
