Dual channel memory question
in [Debian]
|
From: Hugo Vanwoerkom on 15 Apr 2010 16:10 Hi, The Wiki on dual channel memory says: "The memory modules are installed into matching banks, which are usually color coded on the motherboard. These separate channels allow each memory module access to the memory controller, increasing throughput bandwidth." Does that mean that placing 2 1GB modules, each into a different colored slot, is faster than putting 1 2GB module into one slot and leaving the other 3 slots empty?

I have one module in a dual-channel mobo and it works ok. Most desktop/workstation mobos do. -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

The latter will use a single channel squema but I'd say you shouldn't perceive any noticeable difference in your "day to day" work :-) I always try to fill the RAM slots of the board at their maximum capacity (at least 2 GiB.) so upgrading memory will be worth for it.
