顯示卡會吃記憶體?

我的記憶體為256*2=512MB
但BIOS只抓到448MB
有人說是被顯示卡吃掉了64MB
可以不要分給顯示卡嗎
CPU P4-1.8G
主機板 承啟9BJA
顯示卡 ennyah ATI RADEON VE (64MB SDR)

如果你的 顯示卡是OnBoard的話就沒有辦法!!
顯示卡的Ram就是Share主記憶體的,解決方法只有另外接一張顯卡!!

這片板子 是內建顯示ㄉ嗎?

[Omar Lin]

我去查,尚未查到資料!!

我想..m6686 兄檢查casing後面時候有多少個顯示器的接頭比較快吧, 一般是藍色的. 如果只有1個, 就是沒有內建顯示了. 2個的話, 就代表有內建顯示, 那麼到bios裡頭把share ram調整吧.

查到了,但是並沒有顯示卡OnBoard,我覺得這不太可能,怪怪的,bigelephantz

老實說他可能有一片是128M 或是兩個記憶體不同廠牌所產生ㄉ衝突 或是記憶體故障 還是BIOS老舊 我只能往這方面去猜ㄝ 參考

I845板子沒有內建VGA...我認為是記憶體出問題了建議將兩條256分開測試看
能否都正常運作..

是這一塊沒錯
是單獨的顯示卡
恩雅 ATI RADEON VE (內建64MB SDR)

這一張9BIA也是I845晶片組阿沒有內建顯示功能阿.....你還是換測一下記憶體
應該不可能被"吃掉"64MB才對...應該是記憶體模組出了問題才對..

[Omar Lin]

嗯,我也建議照副大所說去試!!

真的有一條記憶體故障
原本應有256卻只抓到192
多謝眾高手幫忙
