手提電腦的影像卡

原來手提電腦公司會將影像卡的速度調慢了！到最近我才知道。日前加了內存512MB(RAM)，就看看是不是也可以升級影像卡。在GOOGLE上查了，才發現一直以來，所用的手提電腦上的影像卡是被慢了。據說這是為了省電和系統隠定。氣！我把它調到卡製造商所公佈資料一樣，銀幕大亂；90%，ProE當機；80%，目前沒問題。其是GeForce FX Go5200可支援AGP X8，但因我的手提電腦主機板只支援AGP X4，故並沒有發揮最大效用。而換影像卡的幫忙也許不大，主機板才是瓶頸。

調法如下：

REGEDIT

[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NvTweak]
CoolBits=dword:00000003

That is, add a Dword called Coolbits and set the hex value at 3.

Once you reboot, go into the Advanced tab of the Display settings, and under the nvidia tab, there will be a new option called clock settings or something (can't remember the name right now, but you'll find it).

After doing this, I found that Dell has done exactly the same as Toshiba. So far though, I've only managed to stably run it at 265 clock and 530 memory. Crashes at 290 and 580, but haven't tried anything in between.
