| FOOTNOTES [Δ] |
- Attained via two 2Rx8 512MB PC133 non-ECC SO-UDIMMs, not possible with 1Rx8 512MB PC133 non-ECC SO-UDIMMs. Irrelevant uninteresting fun fact: 1GB PC133 SO-DIMMs exist, but they're generally ECC and registered/buffered. Sometimes, they come in 4Rx8 or 2Rx8 configurations, which may not be supported by the memory controllers used in normal laptops.
- Attained via one 2Rx8 512MB PC133 non-ECC SO-UDIMMs, not possible with 1Rx8 512MB PC133 non-ECC SO-UDIMMs.
- Comes with factory-installed PC133 SDRAM for some reason, but the memory controller is limited to PC100 speeds.
