Which Ram I should buy?

你好!

首先, 我唔知你有幾多條ram槽...不過無論你有2條/4條(通常都係咁)都好, 先要明白ram係一對對咁配好 o既...因為咁樣行到Dual Channel 機會大好多

1.假設你有4條ram槽, 本身有512MB X 2, 則加多兩條512MB為佳

2.假設你有4條ram槽, 本身為1GB X 1, 我都建議買兩條1GB, then拆左舊ram唔用...因為未必夾舊ram(只加1條1GB風險較大)

3.假設你有4條ram槽, 本身為256MB X 4(咁無良!?), then拆2條256MB再加2條1GB

4.若只有兩條ram槽, 本身有512MB X 2, 柝哂then add two 1GB

5.若只有兩條ram槽, 本身為1GB X 1, 建議換兩條1GB, 原因同"3"

另外, 若你買高D頻率 o既 ram, 佢都會配合較低速一條/底板最高支援頻率而運行, 加上而家普遍DDR2 667比 DDR2 533平, 不仿考慮DDR2 667

price list參考: http://www.jumbo-computer.com/pricelist.asp

A-DATA DDR-2 667MHZ 1G Ram HK$ 315.00
A-DATA DDR-2 533MHZ 1G Ram HK$ 330.00

店鋪方面, 以上網址的jumbo@旺電都幾多人幫襯, 不過去where買都好最緊要check下包裝上面有冇代理貼紙/入面有保用證等, 唔好買錯水貨

希望幫到你啦, 有問題歡迎再補充, 我會盡力答

1. That means you can only have 2 slots to install ram on your motherboard, so you can only have 2 ram at the same time.

2. Are you sure you have one 1GB ram on your motherboard instead of two 512MB ram? As I have mentioned, there are only two ram slots. Besides, some ram may not compatible with your original ram.

That's why I suggest you to buy two 1GB ram and replace the original one(sometimes different batch of ram, even the same model, may not compatible, too. So, it is safe to buy them at the same time.).

3. Sorry, I don't know much about that plaza. The nearest computer plaza should be "298 computer plaza". It's near the Wan Chai MTR station A4 exit.

I can't tell you which shop is reliable as I doesn't go there often, but just check the price, and for most of the ram, such as "A-data", check out if there is a sticker by "憶智" company which is the agency in HK.

朋友：
　　你部主機能否同時使用更高速的記憶體是決定於它的
底板規格（ｓｐｅｃｉｆｉｃａｔｉｏｎｓ）是否說明容
許，還有是否有雙通道的功能都是，要找到它的規格表就
要到你廠機的官網處或聯絡它的服務中心；要買聽說最好
是同廠和要終生保用的；以下两處店鋪都可找到：
腦博仕（香港）有限公司；
Ｊｕｍｂｏ　Ｃｏｍｐｕｔｅｒ　Ｓｕｐｐｌｉｅｓ，　
這两間店鋪在本人買時察覺並無任何不好的動靜。
