NOTES:

Memory:

- Increases system performance by about 30% on most systems.

- Most common computer upgrade component.

Musts When Upgrading Memory:

- Match speed of memory

- Buy from either:

- Crucial

- Kingston

Types of Memory:

- SDRAM

- 2 notches

- 168 pins

- 66, 100, and 133 MHz

- DDR SDRAM

- 1 notch

- 184 pins

- 100, 133, 166, and 200 MHz

- DDR2 SDRAM

- 1 notch

- 240 pins

- DDR specifications

- PC1600

- PC2400

- PC2700

- PC3200

- For Windows XP run at least 512 MB RAM

- Many older systems, and some newer systems using RAMBUS memory needed to have "paired" memory sticks.

- Dual-channel architecture effectively doubles the bandwidth of you RAM, increasing overall speed.

- With unmatched sticks of memory, a dual-channel-capable motherboard runs in single-channel mode.

- Total system speed = system bus times system multiplier. DDR memory is twice the speed of the bus.

- Dropping the speed of your memory will also drop the speed of your system bus, thus overall speed.
