PC-100This is 100MHz SDRAM memory in 144-pin SO-DIMM form-factor. |
Available memory types from IBM
| Partnumber | FRU | Description |
|---|---|---|
| 20L0253 | 20L0263 | 32MB PC100 SDRAM NP SO-DIMM |
| 20L0254 | 20L0264 | 64MB PC100 SDRAM NP SO-DIMM |
| 20L0255 | 20L0265 | 128MB PC100 SDRAM NP SO-DIMM |
| 33L3069 | 33L3070 | 256MB PC100 SDRAM NP SO-DIMM |
NOTE!
As PC-100 memory is getting increasingly difficult to aquire, PC-133 memory can be used instead. Using PC-133 memory will not increase system performance, as it will be run at only PC-100 speed.
