在入手真香前也是用i皇的CPU長大的
國中時的山迪橋遇到奇怪的BUG,硬碟不知道怎麼就不能讀了
只知道主機板就被送修了...
後來才知道是晶片組的鍋~~
之後又換了6400的CPU,滑鼠會不定時定住,只能重新開機才又正常。
先後換了RAM,電供還是不能解決問題,最後查到可能跟內顯有關,
剛好入手獨顯就正常了~~後來整組淘汰時才送修換一顆回來~~
到了AMD沒遇過什麼CPU的問題,顯卡電供都發爐過,主板音效掛了幾次,
風扇也壞過幾顆~~就那CPU都好好的從1700 2700X 3500X 3600 3700 3900X
都有先後或同時玩過就沒在家用常見的windows遇到過bug
之前有段時間在賣水貨CPU,也提供買家代送修服務,賣出了破百顆,
沒有遇過真的需要送修的,來問的都是主機板BIOS沒更新...更新後就好了
算過如果故障是隨機發生的那在95%信心水準下年故障率低於3.7%
不知道有沒有人有大量i皇的CPU數據?我猜應該不小於3.7%
#覺得i皇會定期換腳位還是有它的優勢,但對消費者的荷包就QQ了
#AMD 故障多??先回去檢查BIOS吧~~
------------------------------
補個計算方式
95%信心水準,使用clopper–pearson interval,T是樣品數,B是壞品數
下限=IF(B=0,0,B/(B+(1+T-B)*FINV(0.025,2*(1+T-B),2*B)))
上限=IF(B=T,1,(B+1)*FINV(0.025,2*(B+1),2*(T-B))/
(T-B+(B+1)*FINV(0.025,2*(B+1),2*(T-B))))
