A new BIOS? Seriously? What bios version do you have?
Your board supports up to 8GB memory. Look at page 14 in this link:
I have attached the LAST bios for your board from December 2010 (0037). Note that your board was made in 2009.
Also, what is your processor model number? And, what operating system? If 32-bit, forget about going over 4GB.
Also, note the paragraph on page 14:
"NOTE System resources and hardware (such as PCI Express) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1 GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system. "
хм, в BIOS я изменил частоту ОЗУ с 800 на 667. И 4 из 4 ГБ стали доступны.. Сколько я потерял в исполнении ? Неужели все это обратно 800? Мой процессор: Intel Core 2 Duo e7500
