NOTE!
As PC66 is getting increasingly difficult to acquire, PC133 can be used instead. Using PC133 may or may not increase the performance of your model, as some models may underclock it to their respective original DRAM speeds.
PC66This is SDRAM at 66 MHz in a 144-pin SO-DIMM form-factor. |

FOOTNOTES [Δ] |
- Attained via one 2Rx8 256MB PC100 non-ECC SO-UDIMMs, not possible with 1Rx8 256MB PC100 non-ECC SO-UDIMMs.
- Attained via two 2Rx8 256MB PC100 non-ECC SO-UDIMMs, not possible with 1Rx8 256MB PC100 non-ECC SO-UDIMMs.
- Attained via two 1Rx8 128MB PC66 non-ECC SO-UDIMMs.
- This model accepts EDO 60ns DRAM, but it is not recommended to use older DRAM technology.
- This model uses the 430TX chipset, which means it is hardware-limited to 256MB of RAM as its maximum capacity.
- Due to some odd limitation of the motherboard or the BIOS, the maximum amount of RAM that can be detected is 512MB.
