Upgrade Path:
  • Virtually any configuration up to 4GB can be reached using 256, 512MB, and 1GB modules IN PAIRS.
  • Kingston supports both 333MHz (KTH-XW4100/xxx) and 400MHz (KTH-XW4100A/xxx) DDR SDRAM.
  • Systems shipped with 800MHz FSB processors should use DDR400 parts.
  • Systems shipped with 533MHz FSB processors should use DDR333 parts.
  • Both speeds are supported.
  • However, when running at 800MHz FSB, DDR333 will clock at 320MHz only.
  • If 4GB is installed, the recognized memory may be reduced to 3.5GB or less (depending on system configuration and memory allocation).
