Citace:
Standard DDR3 PC3-8500 (1066 MHz)* or PC3-10600 (1333 MHz)* SDRAM
Two SODIMM slots supporting dual-channel memory
1024 MB, 2048 MB, and 4096 MB SODIMMs
Maximum Upgradeable to 8192 MB with 4096 MB SODIMMs in slots 1 and 2
Dual-channel Maximized dual-channel performance requires SODIMMs of the same size
and speed in both memory slots.
Takže oba dva sloty obsazeny. 2 GB + 2 GB = 4 GB
Šla by jedna paměť vyměnit za 4 GB, ale ztrácí se efekt dualchannel.
Já bych se na to vykašlal a bral bych to tak jak to je.
