Hey I'm going to buy 4x 8gb ddr3 ram.

Should I buy 1600mhz crucial ballistix tactical(cl8), gskill ripjaws 1866mhz or 2133 mhz(both cl9).
The price is almost the same.
If i can't get my pc to run the gskill at 2133, will they then be slower at 1600mhz than the crucial?

It comes down to if you've won the intel chip lottery or not as the IMC is on your cpu. So if you're 3770k (great choice btw!) can play well with those memory speeds, it will run them. If not, it will clock down to the speed it can handle if on auto. If you manually set them it may be unstable and crash, hang etc worst case. Hopefully you get a strong chip and you can get the full speed of you're ram which in this case should be 2133. Also it helps if your motherboard is designed to run at that memory speed as well. I recommend getting the 2133 particularly when the cas is the same as a lower speed chip; that's excellent. It's better and more likely to be stable at that speed (2133) vs OC'ing a slower module (eg the 1866 to 2133)...

On a related but slightly different note, if worst case this 3770k is stable at a slower speed than your 2133 rated ram is, should you sell or upgrade later and use this same ram and pair it with a better chip later (say you upgrade your mobo and cpu in 3years) you can plug and play (assuming we haven't upgraded to ddr4 yet) and know you have ram that's good for that speed and that next chip will utilize it at no extra cost to you! Also resale value will be better. Also, the 2133's will obviously be running cooler or at worst the same temp as the slower rated modules as they are being "downclocked" in your worst case scenarios. Hope this help! Have fun!

Thanks,
