Ah well in that case the G-Skills are indeed better

RAM latencies will inherently increase as frequencies increase, it is inescapable. DDR3, IIRC, the lowest it can go is CL6. Not to mention that on modern Intel platforms, you gain more from higher freq.s, even with the higher latencies.

(However, you won't notice a difference. For me, ~2000 MHz @ 8-8-8-24, and ~ 1700 MHz @ 7-7-7-21 is indistinguishable as far as say, game loading screens; both reduce load times tremendously.)

Why do people seem to rave over this Dominator kit when it's more expensive and seems identical to this OCZ kit (8-8-8-8-24 @ 1600MHz)?

Unfortunatly some people think the more they pay the better it gets. Corsair welcomes such costumers.

We try to actually keep a nice record of the ic's they used on the ram, not sure how up to date it is though. http://www.overclock.net/amd-memory/...-ic-chips.html

But you'll find many ram using the exact same ic's and at different price points. That's where binning comes in and if your lucky you can usually buy the lower binned/less expensive ram kits and clock just as high.

Or as you have seen from different Companies and if you research may use the same ic's.


Edit: List isn't very up to date, but it's an example that you can find some ic's and locate which company is likely to use them.

My DFI board lets me set the CL as low as I want (I could run 1-1-1-1-1T lol). Also I've seen tests where DDR3 was tested at CL 5. Where did you get that number from? RAM can be set as low as the chipset/motherboard allows it to go.

I got that number in the form of utter hearsay via OCN.

It may well have been CL5 though. Just because you can key in the digit though, doesn't mean it will boot. (However, I am not really prepared to defend this point, as I have said, I thought I heard on here that DD3 won't do lower than either CL5 or 6.) IIRC, I heard this from Kuntz, who seems knowledgeable about RAM. At least I think I did, but I guess I should ask him, I don't want to misquote anyone.

Increased latencies are a fact of life with increased frequencies though, which is because of the need for a minimum signal sample, according to my Googling.

So yeah, I kind of just figured if I raised this question/point, phrased with some self-doubt, someone who does understand would correct me. I promise I didn't just make this up out of whole cloth, but I may have mangled it to the point where it is the same thing.

Edit: He seems to have PM turned off.
