電腦主板的選購技巧
1、看芯片組
芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組決定了(le)主(zhu)板(ban)的(de)(de)定位,也(ye)幾(ji)乎決定了(le)主(zhu)板(ban)的(de)(de)全部功(gong)能(neng)(neng)。需(xu)要注意的(de)(de)是,不(bu)(bu)同芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組的(de)(de)主(zhu)板(ban)并不(bu)(bu)會(hui)影響(xiang)CPU的(de)(de)性能(neng)(neng),但(dan)會(hui)影響(xiang)其他部件(jian)的(de)(de)性能(neng)(neng)。Intel主(zhu)板(ban)芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組有(you)四個(ge)等級,分(fen)別(bie)(bie)為(wei)X/Z/B/H,其中(zhong)X字(zi)母開(kai)頭(tou)的(de)(de)芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組,可用來搭配高端(duan)CPU,H字(zi)母開(kai)頭(tou)為(wei)入門(men)級芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組。AMD主(zhu)板(ban)芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組有(you)三個(ge)等級,分(fen)別(bie)(bie)為(wei)X/B/A,其中(zhong)X字(zi)母開(kai)頭(tou)的(de)(de)芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組,支(zhi)持自適應動(dong)態擴頻超頻,A字(zi)母開(kai)頭(tou)為(wei)入門(men)級芯(xin)(xin)(xin)片(pian)(pian)(pian)(pian)(pian)組。
2、看兼容擴展性
兼容越高,擴展性越強,電腦(nao)主(zhu)板(ban)就(jiu)越容易升(sheng)級(ji)改造(zao),同樣價(jia)格也就(jiu)越高。例如需(xu)要顯卡(ka)性能的(de)(de)(de)用戶在(zai)選擇主(zhu)板(ban)前,就(jiu)要看好(hao)對(dui)顯卡(ka)的(de)(de)(de)支持。一般來說,不同芯(xin)片組的(de)(de)(de)主(zhu)板(ban)能夠(gou)提供的(de)(de)(de)功能是有限的(de)(de)(de),由于芯(xin)片組PCI總線的(de)(de)(de)限制,入(ru)門級(ji)的(de)(de)(de)主(zhu)板(ban)無法兼顧到(dao)很多功能,因此兼容性會受(shou)到(dao)影響。
3、看主板接口
高端(duan)主(zhu)板(ban)提(ti)(ti)供(gong)(gong)(gong)CPU供(gong)(gong)(gong)電為4+4pin的(de)接(jie)(jie)(jie)口(kou)(kou)(kou),它可以提(ti)(ti)供(gong)(gong)(gong)更大電流的(de)穩定性(xing),也就(jiu)是(shi)支(zhi)(zhi)持CPU超(chao)頻等工作,對(dui)CPU有超(chao)頻需求(qiu)和經常滿載使用的(de)玩家應該優先(xian)選擇具(ju)備4+4pin接(jie)(jie)(jie)口(kou)(kou)(kou)的(de)主(zhu)板(ban)。如(ru)果你想要(yao)4根內存(cun),那就(jiu)需要(yao)具(ju)有4個(ge)插槽的(de)主(zhu)板(ban)提(ti)(ti)供(gong)(gong)(gong)支(zhi)(zhi)持,同樣(yang)地,如(ru)果對(dui)前置(zhi)USB3.0接(jie)(jie)(jie)口(kou)(kou)(kou)和SATA3.0接(jie)(jie)(jie)口(kou)(kou)(kou)有要(yao)求(qiu),也都需要(yao)在主(zhu)板(ban)上體現。
4、看主板用料
主板(ban)的(de)(de)用(yong)(yong)料(liao)也直接關系到其穩(wen)定性和使用(yong)(yong)壽命,大多數(shu)沒有(you)特殊標(biao)明的(de)(de)主板(ban)均為(wei)四層PCB,這種(zhong)主板(ban)一般用(yong)(yong)于中(zhong)低端(duan)(duan)產(chan)品。而六(liu)層由于屏(ping)蔽層的(de)(de)緣故,更加(jia)容易設計出穩(wen)定的(de)(de)產(chan)品,因此被(bei)用(yong)(yong)于高端(duan)(duan)產(chan)品。但產(chan)品的(de)(de)穩(wen)定并(bing)不(bu)能簡單認(ren)為(wei)層數(shu)越多越穩(wen)定,重要的(de)(de)還是在(zai)于RD和Layout的(de)(de)水(shui)準。
5、看電容
主板電(dian)(dian)(dian)(dian)容(rong)(rong)是(shi)儲(chu)存電(dian)(dian)(dian)(dian)荷的容(rong)(rong)器,它的作用是(shi)保證電(dian)(dian)(dian)(dian)源(yuan)對主板及(ji)相關配(pei)件的供電(dian)(dian)(dian)(dian)穩(wen)(wen)定(ding)性(xing),過濾掉電(dian)(dian)(dian)(dian)流(liu)中的雜波(bo),再將純凈(jing)的電(dian)(dian)(dian)(dian)流(liu)輸(shu)出(chu)給cpu和內存等(deng)配(pei)件。電(dian)(dian)(dian)(dian)容(rong)(rong)對主板穩(wen)(wen)定(ding)性(xing)影響較大,尤其是(shi)主板供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)路所使用的電(dian)(dian)(dian)(dian)容(rong)(rong),這部分電(dian)(dian)(dian)(dian)容(rong)(rong)主要對輸(shu)入(ru)電(dian)(dian)(dian)(dian)流(liu)做第一(yi)次過濾,如果(guo)這部分電(dian)(dian)(dian)(dian)容(rong)(rong)出(chu)現問題將直接影響電(dian)(dian)(dian)(dian)腦的穩(wen)(wen)定(ding)性(xing)。一(yi)般說來日(ri)系電(dian)(dian)(dian)(dian)容(rong)(rong)性(xing)能比(bi)較好,在耐壓、耐溫、使用壽命等(deng)方面都比(bi)臺系電(dian)(dian)(dian)(dian)容(rong)(rong)優秀(xiu)。
挑選電腦主板要注意什么
1、注意細節
挑(tiao)選電腦主板(ban)時,應(ying)仔細(xi)觀察主板(ban)各(ge)芯片的生(sheng)產日期(qi)和型號、品牌標識。各(ge)芯片的生(sheng)產日期(qi)不宜超過三個月,芯片上的標識要清(qing)晰可辨,無劃(hua)痕等明顯印跡。
2、不要過分迷信超頻主板
一(yi)(yi)(yi)般(ban)來(lai)說,超(chao)(chao)頻、極(ji)致板(ban)(ban)的(de)(de)主(zhu)(zhu)板(ban)(ban),質量要求更為嚴格。然而(er)(er)實際上(shang),真正使用(yong)超(chao)(chao)頻主(zhu)(zhu)板(ban)(ban)的(de)(de)人(ren)很少,因為對于一(yi)(yi)(yi)位追求穩定(ding)的(de)(de)用(yong)戶而(er)(er)言,這樣一(yi)(yi)(yi)款主(zhu)(zhu)板(ban)(ban)大部(bu)分功能都已(yi)經被浪費了。而(er)(er)且用(yong)戶還要為那些(xie)自己用(yong)戶到(dao)的(de)(de)功能和技術買(mai)(mai)單,仔細算(suan)來(lai)實在(zai)(zai)不值。值得注(zhu)意(yi)的(de)(de)是,一(yi)(yi)(yi)些(xie)打(da)著超(chao)(chao)頻旗號的(de)(de)主(zhu)(zhu)板(ban)(ban)卻并沒有做到(dao)這一(yi)(yi)(yi)點,但這樣的(de)(de)主(zhu)(zhu)板(ban)(ban)往(wang)往(wang)在(zai)(zai)價格上(shang)十分吸引人(ren)。用(yong)戶在(zai)(zai)購買(mai)(mai)這類主(zhu)(zhu)板(ban)(ban)時的(de)(de)確也能夠超(chao)(chao)頻,但超(chao)(chao)頻行為會加重主(zhu)(zhu)板(ban)(ban)以及其他配件的(de)(de)工(gong)作負荷(he)。所以,消(xiao)費者在(zai)(zai)選購主(zhu)(zhu)板(ban)(ban)時應當擦(ca)亮雙眼,莫讓廠商蒙蔽了雙眼。
