Dual Channel Ram question

[SZLiao214]

I have a msi pt 880 motherboard that i used to run dual channel with, but all of a sudden that no longer works.

I used to run my ram in the 1-3 position and that worked fine till the problem occurred. 1-3 no longer works, 2-4 used too but doesn't work either now. I had to run it at the 1-2 position in single channel mode in order to get it to work. Any recommendations on how to get it to work?

The BIOS is your friend.

Indeed. I'm betting you updated it or knocked the battery out during a recent upgrade, the first might not wipe your settings, but the second sure will.

Another possibility is overclocking...for example, my EE proc has a ceiling of 3.6G, but if I go over 3.2G the dual-channel is lost. I've heard this to be an issue elsewhere as well.

Ah, i had been running my cpu oced from 2.4 to 3.1 for a very long time while i had dual channel. The cpu wont even go to windows if i try to put it in dual channel mode
