Что может быть?

[БТР]

почему не написал, что за модель железки?

если ноутбук, то это аппаратное ограничение - спасибо производителю.

Это не ноутбук.

— Я был в командировке и на одном из тамошних компьютеров, который мне выделили тоже была похожая проблема, потом поставили одинаковые планки убрали три разноразмерные   и стало всё нормально работать …
— Может в этом причина? Не знаю…

[Хрюшка]

Вот блин, только бы не это

Но значит, что 2Гб планка определяется работает как 1 Гб? Такое вообще может быть?

[peregrine]

Хрюшка, планки, подключённые в разъёмы должны быть одного размера (попарно), т.е. в 4-ёъ слотах могут стоять 2 планки по 1 Гб и 2 планки по 2 Гб (обычно в разъёмах одинокого цвета должны стоять планки одного размера). Можете в биосе 2-ух кнальный режим выключить, но память станет более тормозной.

[Хрюшка]

А ведь надо попробовать переставить две планки по гегабайту на один канал, а планку 2гб. оставить в другом канале одной.
Попробую отпишусь.
