PC2100This is DDR (Double Data Rate) memory in 200-pin SO-DIMM form-factor. |
|
Available memory types from IBM or Lenovo
| Partnumber | FRU | Description |
|---|---|---|
| 10K0028 | 10K0029 | 128MB PC2100 DDR-SDRAM CL2.5 SO-DIMM |
| 10K0030 | 10K0031 | 256MB PC2100 DDR-SDRAM CL2.5 SO-DIMM |
| 10K0032 | 10K0033 | 512MB PC2100 DDR-SDRAM CL2.5 SO-DIMM |
| 10K0034 | 10K0035 | 1GB PC2100 DDR-SDRAM CL2.5 SO-DIMM1 |
NOTE!
As PC2100 memory is getting increasingly difficult to aquire, PC2700 memory can be used instead. Using PC2700 memory will not increase system performance, as it will be run at only PC2100 speed.
