Thanks for the link, will take a look at it a little later today.

But going back to post by 636cc of fury...would like to hear as to what exactly he meant and what is the basis for his post.

...I'm not questioning him, I'm just trying to add to my knowledge base.

More channels in use generally fares worse in synthetic latency tests.

I haven't really played around with this much on my LGA-2011 setups, but latency in things like MaxxMem were significantly better with only one or two channels populated on my LGA-1366 systems.

However, real world performance is usually the same or worse, with fewer channels, especially when using lots of threads or multitasking.

Wish I still have my X79 setup and I would show you, but I along with others (Fredyama-san, Andre) can confirm this for 32M when we were testing at X79 launch, not sure for everything else though.

Are you saying that the system performance is better in triple-channel vs quad-channel, or that the ram will clock higher...or if neither of those, then what will run faster?

System performance for SuperPi 32M will be better is what I am saying:thumb:

Blameless & 636cc of fury,

Thanks for your replies. I'll have to play around with that a little bit.
