Does CL Rating Matter Anymore?
I'm looking to swap out the RAM in my rig as it's the only thing that doesn't match a color scheme. (I know that's a retarded reason, but I know I'm not the only one that would do this...) I started looking through 'black' RAM options for a good buy, and it occured to my that the extreme speeds of RAM these days seems to have reduced the requirement for lower CL. A good case in point is the 1800MHz CL11 RAM that G.Skill has pasted in flash banners all over HWC right now.

So at the end of the day, I'm curious if CL rating makes any real world difference past 1600MHz? Especially since the jump from CL10 or 9 down to CL7 is absolutely crazy in price in most cases. I understand the concept, but I really don't know how the math works for MHz vs. CL to find out what the difference is. I know that it won't matter in gaming, but I'm also interested in day to day functions, as well as photo work.

Short answer, no. Check this article out. Back in the day (Socket 7) I remember reducing the latency on my sdram really gave it a kick in the pants. But today it does not have that same effect.

It will make a real-world difference in synthetic benchmarks. :biggrin:

I would like to add though, if your OC'ig your rig you could limit yourself by buying slower modules. If you don't plan to OC then save the money cause it's a wash. And yes, real world synthetics would be drastically hampered by all that slow ass ram. :haha:

Edit: I think of bigger concern would be compatibility. I'm not sure of the situation these days but I hope things are better than they were six years ago.

The simple reason being that the increase in speed more than makes up for the increase in latency.
