Some RAM questions

[overclocker]

Hi guys, Im planning to get some new memory to replace by crappy ones now. Saw that the Corsair DOMINATOR GT is quite good, 2000MHz, 7-8-7-20(https://shop.corsair.com/store/item_view.aspx?id=766411).
I want to ask:
1. Doesn these ram run at 2000MHz once they are installed into the pc? Does that mean 4000 uncore on a X58 system?
2. What is Intel XMP? How do i get it?
3. Which is better, higher speed frequency or lower latency?

Thx a million!!

Hi.

1- Does mean that u want waste ur money, go with 1600 since the difference between 1600 and 2000 is <1%. When u install the RAM, that only can run at 2000MHz not a 4000MHz as u say.
2- XMP is a pre-overcloked RAM. In other words, are RAM profiles to OC depending of ur needs and profile that u select.
3- The better is High speed AND lower CL.

So does that Corsair ram support XMP? Do I get to choose the profiles right after I installed the ram?

1- I'm not sure if that Dominator support XMP, u can contact to Corsair to know that.

This two support XMP:

b- http://www.newegg.com/Product/Product.aspx?Item=N82E16820145269

P.D. The difference between 1600 and 2000 isn't big, so, don't waste ur money in that 2000 kit and go with the 1600 kit.
