2GB of RAM instead of 1 GB for an "old" eeePC 901 accompanying me throughout my travels ... Product delivered within the time specified under rigid shell. No difficulty to open the hatch of the eeePC and root out the barrette RAM of origin (one location), but the new barrette has been recognized by the system after a brief passage through the BIOS (F2 at startup) . None reported malfunction. Nor were revolution but Big images open faster. It should be noted that my eeePC has no hard drive but a 16GB SSD, and that without virtual memory on the disk (no swap file), everything happens in RAM. XP SP3 system
