謝謝cmwang大的回答
這麼看起來我的問題跟BIOS關係似乎不大?
那為何MB廠商的說明書都有最大記憶體支援的規格?
還請您開是一下

以下引自S754 functional data sheet(鵝手邊沒有AM2的
)....
2.4.2 Memory Controller
The processor’s memory controller provides a programmable interface to a variety of standard DDR SDRAM DIMM configurations. The following features are supported:
• Self-Refresh mode
• Unbuffered and registered DIMMs with a 64-bit data bus with optional 8 bits of Error Correcting Code (ECC) in one of the following two configurations:
— Up to three unbuffered DIMMs according to the loading described in the BIOS and Kernel Developer’s Guide for the AMD Athlon™ 64 and AMD Opteron™ Processors, order# 26094.
— Up to four registered DIMMs
snipped....
• DIMM sizes from 32 Mbytes (using 64Mb x16 DRAMs) to 4Gbyte(using a stacked, registered DIMM with 1Gb x4 DRAMs).
snipped....
照字面上看來光S754就support 4條4GB ECC Registered DDR共16GB了(如果您願意不計血本的話
),沒有道理更高階者反而倒退吧

由於有這樣需求的是WINDOWS BASED的程式
可否指點一下目前32BIT與64BIT的WINDOWS最大支援的記憶體為多少
謝謝

鵝對Win不熟沒辦法給您太多意見,不過一般講法32bit OS就算透過PAE support >4GB RAM效能也會打折,而且一般3rd party的RAM DISK能不能support >4GB的環境也屬未知
