Ganged vs. Unganged Mode

post #1 of 154
4/25/08 at 5:30am
Thread Starter 
I've seen a lot floating around the internet about Ganged and Unganged modes for PC RAM. I don't think I'm the only one that has questions about it, but being that info on it is scarce, I thought I would start a thread so that others could post info about it (Unfortunately I don't know a whole lot about it, so that's another reason too )

What is Ganged Mode?

What is Unganged Mode?

Which Mode is Better?

What exactly does it do?

It is amd's version of Nvidia's Locked vs unlocked architecture.

basically allowing you to use your ram in dual channel vs single channel.

Ganged = dual channel mode for ram. All cores get access to 100% of the ram.

unganged = single channel. Each core gets access to a stick of ram.

In theory, the unganged mode is better as each core will get access to data quicker. In theory.

Some limitations apply... and i dont know muchelse.

Edit: sorry, it also alows you to control the clocks indipendantly from eachother.

Good deal. Thank you for the answer . I'll have to play around with it. Might have to wait until I get 4 stix of RAM to be able to use it properly with my Phenom.

Is this an option in the bios, or do I just stick one stick in slot 1 and the other in slot 2. I have 4 Gigs. 2 x 2gig SLi sticks. Never heard of this. Good question darkvette

I might be wrong but I think this only applies to the Phenoms so I think I'm out of the equation.

I know its an option in the bios of my MB, but not sure if it only works with Quads.

Someone correct me if I'm wrong, but I don't think you need four sticks.... I believe it also works with two.

It will work with only 2. I was running 2 stix of Crucial Ballistix with a 9850BE before one of the stix went up on me. But, yes - It will work with only 2 sticks. 4 work better though, especially if it's 4x2GB - 8GB???

I've heard from a few people that having 8G of ram will result in slower performance, although there is more ram? Is this true?
