are RAM bad quality? SlenderGirl2010-03-02 21:26:41

I bought two 512 memories to increase my laptop's RAM.It was 512 RAM.After I installed these two new chips,my pc shows RAM is 704! It is suppose to be 1G
RAM, what is the problem?Is it possible that one of the chips doesn't work well?

video card used 320MB ( 1024 - 704 = 320 )

可能主板不支持，可能被分配到显卡做显存去了

回复：video card used 320MB ( 1024 - 704 = 320 )

旧笔记本板载显卡能吃掉320M么？通常8-64MB

I tried other 2 new chips, my pc even shows 512 RAM!

好的显卡用单独的内存，video ram，另外显卡驱动可以动态

那是几年前的老皇历的，现在玩3D 256MB都不够

内存不兼容

回复：内存不兼容

很难说，有些人加内存以后问题多多，换个牌子又没事了

有些老笔记本只支持768M内存比如华硕s5A

你的笔记本型号是？

This is what I am going to try to do.Thanks a lot!

If you search you can find many Sony users have

你觉得楼主512MB的笔记本电脑，可能是新电脑么？
