Yes, you could buy 1333 CL9 and OC your CPU to 5GHz. Your memory will have no impact on your CPU overclock whatsoever. The only thing that links the CPU and the memory together is the BCLK, which is a constant 100MHz wtih Sandy Bridge. Whereas previous platforms used the BCLK to do the overclocking, Sandy Bridge strictly uses multipliers. There's a memory multiplier and a CPU multiplier. CPU multipliers go all the way up to 57 and your available memory multipliers in most cases include 13.33, 16.00, 18.66, and 21.33. Multiply that by the 100MHz BCLK and you have your speed in MHz for the CPU and the memory.

Well, I can understand your explanation. What I can not understand is this: I buy my computer for example with 2 sticks of 4096MB (4 GB) 2000MHz CL8 memory, then I overclock my system to what I want (I don´t know how to do it, but that´s another step and another topic!), and then I leave the memory like I bought, or do I have to change something in the memory? If I don´t change anything, my memory will still run at 4096MB 2000MHz CL8?harpsi

Question: b. For this processor, which motherboard to choose: Z68 or P67?Answer: Get the Z68 board, make an SSD cache with a 1 Tb WDC Black 64 Mb, 6 Gbs HDD. http://www.anandtech...aching-review/2

Sorry... I don´t know what is SSD cache with 1 Tb WDC Black 64 MB... (I am not an expert on computers ;))harpsi

The combinated HDD means hard disks of 20 or 40 GB of space. If you have to install more than 300 addons for FSX... maybe even 1 terabyte of space is not enough :DOr do you mean the one with 1 TB for FSX and another one "SSD" for windows 7 64 bits only?harpsi

You will have to go in the BIOS and either set it to XMP profile or manually input the memory multiplier and the timings. It's super easy. Sandy Bridge doesn't have a 20.00 multiplier, so 2000MHz memory would have to be either downclocked to 1866 or overclocked to 2133. Unless you already own the memory, I would recommend buying the memory with exactly the speed and timings you want. That way if it doesn't run at specified speeds, you can blame the manufacturer who guaranteed it and get a replacement set.Here's what the settings look like in my BIOS...Memory Frequency:Memory Timings:

Sorry but I still don´t understand... :(What you are saying is that for example, if I have 3 types of memory - 2133MHz CL9, 2000 MHz CL8 or 1666MHz CL7 - it doesn´t matter which one I choose, or it does matter which one of the three I choose? You can say as an example: it is better 2133 MHz CL9. I can ask you: 1. why this one? 2. why not one of the other two types?Sorry to ask again, but what I still don´t understand is if I can choose two independent things for CPU and memory. For example, for CPU i7-2600k I can not choose socket LGA1366 because it just works with LGA1155. This I know... but for memory plus CPU I thought they don´t have relation with each other. This is what I still don´t understand... Greetings,harpsi

I'm saying Socket 1155 does not support 2000MHz memory. I have no clue why, but it just doesn't. Just get 2133 CL9 and don't look back! Why? Because according to benchmarks, it's faster and quicker. Simple as that.

Ah, Ok. Now, I understand one more things: with LGA1155 no 2000MHZ. So, I should avoid this one. I can not find 2133 CL9. Can it be 1866 or 1600?harpsi

1600 7-8-7-24 is probably the next best choice and can possibly be OC'd to 2133 9-11-10-28 anyway.

Sorry, that´s where the confusion starts... I buy a memory with a specification and I will overclock it like I do with a processor? So, I can have a pure 2133 memory and and an overclocked 1600 which turns into a 2133 memory... LOL, a bit confused for me sorry :\ And what is the interest of this? Sorry to ask...harpsi
