mọi người biết loại memory này là gì không ?
Mình gắn thêm ram 512 DDR PC 3200 (400mhz ), chạy ok . Main chỉ hỗ trợ tới PC2700 thôi .
Theo default thì main sẽ sử dụng tốc độ tối đa hỗ trợ là 333mhz (PC2700) cho thanh Ram mới ??? am I right ?

Test bằng sisoft sandra 2004 thấy thông báo này :warning

Large memory systems (1GB or greater) should use Registered/Buffered memory, especially if more than 2 are installed on the same channel. This improves signal quality by reducing the load on the chipset channel. While these modules add an extra clock delay due to the on-board buffers (thus CL2 effectively becomes CL3), the stability will be worth it. Server chipsets with many memory slots generally require Registered memory.
Fix: If you plan on adding more memory, consider replacing the modules with Registered/Buffered modules. Do note that you cannot mix Unbuffered and Registered/Buffered modules on the same channel, but you may be able to if the chipset has multiple memory channels

Thực ra chỉ tò mò muốn biết nó là gì thôi , vì máy chạy hiện thời ok. Thanks anh em nhìu
