但據我所知這臺動物機(Giada N20)是使用 Atom D525 的 CPU,
Intel 官網寫明了記憶體時脈只能到 DDR3 800MB,
所以先拿之前換下來的 2G 筆電的 DDR3 1333 試試看能不能用…
後來還是買了創見 DDR3 1333 4G 的來用,
因為買不到 1066 的了(想說應該比 1333 便宜才做此選擇)。
還是開機看看比較實在。
開機後發現能夠正常啟動,
BIOS 也能偵測到此記憶體的容量,
證實它是可以升級的,
不過還得進一步查看是不是真的能到達 800MB 的時脈。
進入 Ubuntu 系統後開啟終端機,
輸入下列指令就能看到記憶體大小:
archer@archer-GiadaN20:~$ cat /proc/meminfo MemTotal: 4039032 kB MemFree: 732176 kB Buffers: 147452 kB Cached: 1663988 kB SwapCached: 0 kB Active: 1625396 kB Inactive: 1413496 kB Active(anon): 1229112 kB Inactive(anon): 9132 kB Active(file): 396284 kB Inactive(file): 1404364 kB Unevictable: 60 kB Mlocked: 60 kB SwapTotal: 1999868 kB SwapFree: 1999868 kB Dirty: 1540 kB Writeback: 0 kB AnonPages: 1227520 kB Mapped: 171184 kB Shmem: 10796 kB Slab: 131876 kB SReclaimable: 100356 kB SUnreclaim: 31520 kB KernelStack: 3560 kB PageTables: 36476 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 4019384 kB Committed_AS: 3706972 kB VmallocTotal: 34359738367 kB VmallocUsed: 319296 kB VmallocChunk: 34359402492 kB HardwareCorrupted: 0 kB AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 149056 kB DirectMap2M: 4034560 kB |
如果想得到更仔細的內容(如時脈),
就用這個指令:
archer@archer-GiadaN20:~$ sudo lshw
[sudo] password for archer:
archer-giadan20

所以確定它把記憶體的時脈給降頻了。
