Оперативная память не распознана
Сегодня я поставил новую 8 ГБ ОЗУ, заменив старую 4 ГБ, но она не распознается ни Ubuntu, ни Windows 10 (у меня двойная ОС).
Теперь я распознал только 4 ГБ, потому что я не заменил их обоих.
Я выполнил тест memtest86 +, и все было хорошо, без ошибок. Я видел информацию о новой оперативной памяти на SPD в memtest86 +.
Вот результаты:
