這塊顯卡平常待機時，溫度約在61-62左右
跑個Furmark 30分，升到8-90度，原廠風扇真的很爛超爛，轉速調到100％還是很弱
升到高溫後常常螢幕就整個消失了，沒有訊號
關機後等幾分鐘冷卻再開機，就出現雪花了，
整塊卡拔下來，用電風扇吹十幾分，完全冷卻後
再插上去開機，又整個正常....
正常時跑mats8，整個正常

出現雪花時FBA[31:0] 出現寫入錯誤
正常時跑memtestCL & memtestG80就有錯誤產生，真不知道mats到底準不準

這到底是GPU還是DDR3的問題？
一般來說如果GPU掛了，重焊就能解決問題嗎？因為是寫入出錯，所以我猜是GPU的問題。
高雄有哪位大大有BGA台和熱風槍想試試看。 |
