[Solved] Whats the Best Ram ?

Your choices are not correct. Those memories are tri-channel (X58 mobos). You must look for a Dual channel memory.
Here you have a good option from Gskill:

Yeah, the link of my post are 4GB RAM dual-channel. Are G.Skill and are very good.

Yeah, the G.Skill.

Now, you can know if the RAM is dual channel or tri channel with the number of sticks. For example, 6GB are 3x2GB sticks, so, this is a tri channel kit that only supported by the i7 and mobos with chipset X58 for example.

Now, a 4GB kit is 2x2GB stick, so, that kit is dual channel, that is supported by intel and AMD.

In other words, when you have only one stick of RAM is single channel, when you have two stick with the same specifications, and installed correctly on the proper mobo's slots, you have dual channel. And finally, if you have 3 stick with the same specifications installed correctly on the proper mobo's slots and the mobo support tri channel, you have a tri channel RAM.

Yes, you could buy 4xmodules 2Gb DDR3 to get 8Gb DDR3 at total (or 2xmodules 4Gb DDR3)
You can buy 6Gb (3xDIMM) but in that situation you coudn't run Dual Channel. You will only have 6Gb at single channel (less performance). Therefore, the best option is to buy one or two couples of modules.

In this link you will find a " memory support list" in the menu on the right.

Those numbers are the timings. The lower they are, the faster the memory is.

Here you have a tutorual about it: http://www.hardwaresecrets.com/article/26

G.Skill Ripjaws 4GB DDR3 1600Mhz (2x2G) F3-12800CL9D-4GBRL is faster than G.Skill 4GB RipJaw (2x 2GB) DDR3-1333MHZ, F3-10666CL8D-4GBRM, PC10666

The frecuency of the first one is higher (1660 vs 1333) although the timings are worse. But you wouldn't notice any difference between CL9 and CL8 at the same frecuency. Therefore, choose the first one.

Whait now I'm confused the red rip jaw or the blue???
(1 or 2)
THX

I'd like to put my vote in for OCZ Platinum modules. They have been great on my 8200 for overclocking, they have a 7-7-7-16 timing @1.65V. The G.Skill are good also, but I wanted to give a second opinion, since all the posts so far seem to persuade that only G.Skill will do... IMHO

If you think this is confusing, you'll love RAID.

Seriously, though, RAM does get a little weird.

First of all, dual-channel mode and triple-channel mode have less to do with your RAM sticks than the memory controller on your motherboard. A dual-channel capable motherboard (such as yours) will have a memory controller that can access two channels of memory at the same time, sort of like that scene in "Iron Monkey" where the doctor is writing two prescriptions at the same time, one with each hand: if you have memory installed on each channel, then the memory controller will work with them simultaneously, theoretically doubling the memory throughput. Apparently, there's some disagreement as to whether or not this actually works, but you can read more here. Triple-channel is basically the same idea, but with three channels.

What does this have to do with your choice of RAM? RAM sticks by themselves aren't "dual-channel" or "triple-channel," they're just sold in kits for dual-channel or triple-channel systems; you can either buy the dual channel kit of those RipJaws you're looking at, or you can buy each stick individually. So long as you put them in the right slots in your motherboard, they'll work in dual-channel mode.

What is important is to find memory that will work with your motherboard and processor. Henry pointed out earlier a "memory support list," which is a list of RAM sticks--model, manufacturer, form, speed, etc.--that a motherboard manufacturer--Gigabyte, in this case--knows will work with that motherboard. Going off this list is probably your best bet if you're looking for stability, but you don't have to do that (I didn't). There are plenty of people here who know a lot more than I do who'll steer you in the right direction.

As for RAM speed and timings, they're both important to your overall experience. As others have explained, the RAM speed is how fast the stick runs (1066 MHz for instance), or how many operations it can perform a second (about 1,066,000,000, to be exact). The the latency (or CAS latency or CL) refers to how many clock cycles it takes for the RAM to retrieve a piece of data. So if your RAM has a CL or 8 and a speed of 1066 MHz, it takes 8 cycles for it to respond to a request for data, just as if you asked a friend a question and it took him or her a moment to respond. That's latency. You can go here for more info, and you can read this article to have it explained more in-depth: while the article is a couple of years old, the principles still work.

But if you work out the math, you'll find that 5/1,066,000,000ths of a second is a fraction of a fraction of a second slower than as 7/1,600,000,000ths of a second, and given that the slower clock speed is actually supported by the motherboard, I think you'll find much greater gains in stability and reliability--and therefore performance--at than you will in speed if you go with the 1066MHz over the 1600MHz. (I'm using 4GB of 1066 RAM at 7-7-7-20, and I still get between 170 and 195 fps on Half Life 2, and that's with x6 to x8 AA)

Anyhow, I hope that helps.

Here you have a comparative between DDR3-1333 CL7 and DDR3-1600 CL8 (photoshop, 7-zip and some games). Higher frecuency is better than lower timings, althouh the difference is not very high.

^Perfect, and the Crucial's web site have international shipping, so, you can buy it from the crucial's web site directly.

That is a tri-channel kit. Why? Because are 6GB (3x2GB).

Yeah, the LEDs are awesome, I have Crucial too and are very good.

Yeah, for now is good with 2x2GB, if you want add more RAM in the future, you can add 2x1GB or 2x2GB.

^Yeah they sell 1x2GB, but for performance you always buy on kits. 2x1GB, or 2x2GB or 3x2GB(tri-channel)

Any time, that's why we are here. And enjoy your RAM, is very good.
