裝左4GB Ram..得3.25 Usable... 什麼Hardware Reserved!?!? HELP! thanks!
我想要番4GB!
我係新裝Window 7 64 bit, Upgrade左新Ram同CPU... 2條2GB....
未裝之前係Vista度開都見到4GB Ram... 而家Bios都見到4GB Ram....
但係就唔明點解Window 7 就寫住3.25GD usable.... 無啦啦唔見左7XX Mb...
根住Google左好耐.....又話Hardware reserved, 咩memory remapping 定唔知d咩....
總之咩都根住做, 都係唔得, 請問有無CHING都係咁而又解決到!
Thanks Thanks, 我的setting 如下!

低板ga問題

可以把低板ga電慈拆走,＋分鐘後裝回再着機.如果都係一樣的話,可能低板ga最高的ram值係3GB ram.
