神奇: 四條DDR 1G = 3.6G...
神奇: 四條DDR 1G = 3.6G...有沒有人有同樣情況? It happens particularly when most of the mother boards now in the market come with on-board video, which shares some of the momery though... bios already set video use 16M only.
2 DDR = 2G
3 DDR = 3G
4 DDR = 3.6G

這是因為PCI 的規範原因,當安裝4GB記憶體時,系統只能偵測到3.6GB左右,是因為系統資源(包括ICH南橋晶片、主機板上所安裝的AGP/PCI卡以及其他onboard 裝置)會重新對應到高層的記憶體位址空間,由於在現今32位元的x86個人電腦系統架構下,會從4GB開始以下佔用,因此,系統開機時會顯示少於4GB記憶體,這是現今32位元的x86個人電腦系統架構下正常的現象 。 oh.
即係3g ram底用d... you need a Athlon64 (x86-64 platform) in order to overcome this limit
it's very common on x86 platform where everythign is 32 bits 厲害,1GX4..牛XX [quote]Originally posted by [i]icefire[/i] at 2004-5-23 01:19 AM:

明白了:lol:
厲害!! 32bits CPU has 4GB addressing space limit

4g ddr
咁你部腦要不要$25000
我公司有部腦張video card 差不多$20000
不過我都係用黎睇下dvd,上下網
都吳知咁勁攪乜q野
d公司錢多就+俾我好過啦 [/quote]
我以前公司已用緊double layer 1G [quote]Originally posted by [i]pctong[/i] at 2005-5-17 10:21 PM:

本身用 1G ram 間了256mb 做phy hardisk, 專用來downlad 野同render movie, 但 bad is reboot 就clear, coz 佢係實體ram [quote]Originally posted by [i]pctong[/i] at 2005-5-17 10:26 PM:

Ram disk其實唔係咁有用架咋喎 [quote]Originally posted by [i]趙公子[/i] at 2005-5-26 05:26 PM:
其實唔係咁有用
但速率會快過你靠software 計數,風險就係reboot 同hang 機果時
total lose I'm using dual-Opteron cluster, one of the node has:
XXXX$ free
total used free shared buffers cached
Mem: 3993380 565832 3427548 0 68376 288496
-/+ buffers/cache: 208960 3784420
Swap: 1020116 0 1020116
XXXX$ head -n 5 /proc/cpuinfo
processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 5
model name : AMD Opteron(tm) Processor 248
so for "4GB" ram
there're 3.993380 X 10^9 BYTES
but 3993380/1024/1024=3.808 GB
it really depends on the definition. [quote]Originally posted by [i]pctong[/i] at 2005-6-6 11:29 PM:

but u got a fast access time HD wor (Virtual one),
u save time, u pay for data lost
it is a balance of risk hehe,notebook 最多插兩條 RAM,暫時唔會有呢種問題 :) 4000000000/1024/1024/1024=3.72G左右... **** 作者被禁止或刪除 內容自動屏蔽 **** 算啦,用64bit OS先用得盡
