Xin lỗi với sự cố : [Mong mọi người thông cảm,m chỉ hay tư vấn sư cố hỏng hóc,ko hay tham gia tin tức] m xin copy 1 bài gthich ki nhung ngắn gọn đây để sửa sai về sự cố
Các bạn thực sự vẫn chưa hiểu gì về Core Duo và Core 2 Duo, để tôi giải thích thế này cho dễ hiểu nhé: - Core Duo là dòng chip 2 nhân thật, nhưng có 2 bộ nhớ đệm Cache L2 riêng biệt, mỗi nhân dùng một bộ cache L2 riêng của mình. - Core 2 Duo là dòng chip ra sau, tiên tiến hơn dòng Core Duo, nó cũng là chip 2 nhân thật, nhưng 2 bộ nhớ đệm Cache L2 được nhập lại làm 1 bộ có dung lượng gấp đôi, 2 nhận dùng chung 1 bộ nhớ đệm nên có khi hoạt động cực kỳ linh hoạt do 1 nhân có thể dùng hết toàn bộ hoặc phần lớn bộ nhớ đệm L2 nếu nó chạy các chương trình cần thiết phải dùng bộ nhớ đệm lớn. Nói vậy các bạn sẽ dễ hình dung hơn về sự khác nhau giữa 2 loại chip này.

Compatibility
Information on Core 2 Duo E8400 and Core 2 Quad Q9300 compatibility with other computer components: motherboard [look for socket type], power supply unit [look for power consumption] etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.
