Choosing memory

[josgba2002]

Hi. I'm building a new pc for gaming, but also will use it for working (software like Autocad, Illustrator, Matlab, and occasional video encoding).

I bought this:

Core i7 2600k
Asus P8Z68 V-PRO GEN3

But I haven't choose RAM. I will take a G.Skill (highly recommended). So, between these memory, which is more recommended?



PD: I'm willing to take any other recommendation.

Thanks

G.Skill has NOTHING more too offer than any other major brand RAM manufacturer. Corsair, Crucial, Patriot and Mushkin all offer great products, as good or better as G.Skill. As for your choices, what do you want more? Speed or savings? Check the motherboard compatibility and get the fastest RAM it will support. Easy peasy.

Meh. Faster than 1600mhz won't make much of a difference; you almost certainly won't notice. I recommend that you get something without tall heatsinks, as they're basically useless. They don't do anything but occasionally interfere with CPU heatsinks.

I'll like both (speed and saving, being speed more important). But I have my doubts related to speed and timings. Some reviews show a memory 2133 CL11 having better performance that a 1866 CL8.

I take these maths:

2133/2 = 1066.5 MHz, T = 1/f = 0.94ns, t = T*CL = 10.31 ns

1866/2 = 933 MHz, T = 1.07 ns, t = 8.57 ns

So, if second one looks more fast, why the other win?

Thanks. What model do you recommend?

As cobra said, it doesn't really matter. These would be fine, nice and low-profile: http://www.newegg.com/Product/Product.aspx?Item=N82E16820148544

After reading this:

And this:

http://www.bit-tech.net/hardware/memory/2011/01/11/the-best-memory-for-sandy-bridge/1

This would be best choice:

Any thought?

Uh...no. Those articles both come to the conclusion that memory speed and latency are basically unimportant and that gamers should get inexpensive 1600mhz kits. That's what I said earlier as well.

Well, I do a lot multitasking, so high bandwitch is recommended... That's why I consider a 2133 CL10 1.5V a best choice...

It's not worth the extra money.
