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(nei)存頻率越(yue)(yue)高,其性能就越(yue)(yue)好。目前內(nei)存頻率主要(yao)有:
DDR2內存頻率主要有(you):333MHz和(he)400MHz的(de)DDR內存,667MHz、800MHz和(he)1066MHz。
DDR3內存頻(pin)率主要(yao)有(you):1066MHz、1333MHz、1600MHz。
DDR4內存頻率(lv):2133MHz-4266MHz之(zhi)間。
其中DDR2內(nei)存(cun)如今已經淘汰(tai),很多早年購買或(huo)者更早購買的(de)電(dian)腦均為DDR2內(nei)存(cun),內(nei)存(cun)頻(pin)率普(pu)遍較低,最高也(ye)不過(guo)只有1066Mhz,如今主流的(de)內(nei)存(cun)頻(pin)率是1333MHz和(he)1600MHz頻(pin)率內(nei)存(cun),并且隨著技術的(de)進步,未來DDR4將(jiang)成為主流。
二、如何產看內存頻率
1、看內存表表面標注
內(nei)(nei)存(cun)上一般都(dou)會(hui)標(biao)(biao)注(zhu)內(nei)(nei)存(cun)容量以及頻率等,如果(guo)您是新購(gou)買的(de)內(nei)(nei)存(cun),或者臺式電腦,那么就可(ke)(ke)(ke)以拿(na)出來看看,我(wo)們可(ke)(ke)(ke)以通過看內(nei)(nei)存(cun)表面銘牌標(biao)(biao)注(zhu)即可(ke)(ke)(ke)知(zhi)道。
2、開機看電腦自檢信息
電腦(nao)在重啟或者開機后,在硬(ying)件(jian)自(zi)檢的(de)時候(hou)會(hui)顯示各主要硬(ying)件(jian)詳(xiang)細信(xin)息(xi)(xi),其中就會(hui)包含內存頻率與(yu)容量等(deng)信(xin)息(xi)(xi),我們可以(yi)在電腦(nao)開機硬(ying)件(jian)監測到第二個(ge)畫面的(de)時候(hou),按(an)pause鍵暫停,暫停自(zi)檢畫面看內存頻率信(xin)息(xi)(xi)。
3、借助電腦優化軟件查看內存頻率
使用一些電(dian)腦(nao)優化軟件也可(ke)以檢測(ce)內存頻率,比如使用魯大(da)師檢測(ce)電(dian)腦(nao)硬件信(xin)息即可(ke)檢測(ce)到(dao)內存容量與頻率了。
三、內存頻率的意義
