一、內存頻率有哪些

我們知道內存性能由內存容量以及內存頻率共同決定，在相同容量的內存中，內存頻率(lv)(lv)越高，其(qi)性能就越好。目前內存頻率(lv)(lv)主要有：

DDR2內(nei)存頻率主要有：333MHz和400MHz的DDR內(nei)存，667MHz、800MHz和1066MHz。

DDR3內(nei)存頻率主要有：1066MHz、1333MHz、1600MHz。

DDR4內存頻率(lv)：2133MHz-4266MHz之間(jian)。

其中(zhong)DDR2內存(cun)如(ru)今已(yi)經淘汰，很多早(zao)年購買(mai)或者更早(zao)購買(mai)的電(dian)腦均(jun)為(wei)DDR2內存(cun)，內存(cun)頻(pin)(pin)率(lv)普遍較低(di)，最高也不過只(zhi)有1066Mhz，如(ru)今主流的內存(cun)頻(pin)(pin)率(lv)是1333MHz和1600MHz頻(pin)(pin)率(lv)內存(cun)，并且隨著技術的進步，未來DDR4將(jiang)成為(wei)主流。

二、如何產看內存頻率

1、看內存表表面標注

內存(cun)上(shang)一般都會標注(zhu)內存(cun)容量以(yi)(yi)及頻率等，如果您是(shi)新購買的內存(cun)，或者臺(tai)式電腦(nao)，那(nei)么就可(ke)以(yi)(yi)拿(na)出來看看，我們可(ke)以(yi)(yi)通(tong)過看內存(cun)表面銘牌(pai)標注(zhu)即可(ke)知道(dao)。

2、開機看電腦自檢信息

電腦(nao)在(zai)重啟或者開機后，在(zai)硬件自檢的時候(hou)會(hui)顯(xian)示各(ge)主要(yao)硬件詳細(xi)信(xin)息(xi)，其中就會(hui)包含內存頻率與容量等信(xin)息(xi)，我(wo)們(men)可以在(zai)電腦(nao)開機硬件監(jian)測(ce)到(dao)第二(er)個(ge)畫面的時候(hou)，按pause鍵暫停，暫停自檢畫面看內存頻率信(xin)息(xi)。

3、借助電腦優化軟件查看內存頻率

使用一些電腦優化(hua)軟件也可(ke)(ke)以檢測內(nei)(nei)存頻率，比如使用魯大師檢測電腦硬件信息即可(ke)(ke)檢測到(dao)內(nei)(nei)存容量與頻率了。

三、內存頻率的意義
