Andy and Sean discuss how memory upgrades help improve your computer's performance and the pitfalls you should avoid. 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 - 200, 266, 333, and 400 MHz - 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.
