Оперативная память режется пополам

Здравствуйте!

Недавно собрал себе новый компьютер. От старого остались только диски. В 50% случаев система загружается и видит 32 гига вместо 64. В остальных 50% система видит все 64 гига, но очень нестабильна — зависает через полчаса работы от более менее серьезного процесса (игры, рендер). Пробовал ставить только 2 плашки из 4. Тот же результат — либо стабильные 16 гигов, либо нестабильные 32 гига, причем неважно какие слоты — 1-3 или 2-4. Аналогично с одной плашкой из 4.

Было подобное. Помогло разобрать системник и собрать заново.
Мне тогда помогла переустановка процессора.
