Hey all,

I have an ASUS Z87 Pro mobo with an i5-4690k that I am overclocking. I'm also using a Cooler Master Hyper 212 EVO for cooling the cpu.

My question is which is the better ram to go with from the two X Series below:?

They are within $5 of eachother with the promo code and one is 1866 (CAS=10) while the other is 2133 (CAS=9).

I would assume that the 2133 is the better ram, but my only concern is that the voltage on that one is 1.65 compared to the 1866 which is 1.5. I believe 1.5 is the recommended for haswell chips but am not too sure how needed this is or if it would be better with the 2133 module.

Can anyone give some insight which would be better for my needs? Mainly just gaming on this computer but I do multitask a lot.

Thanks a lot!
 
Solution
The 2133/9 set is the better of the two, if you wanted you could drop it down to 1866 and run with CL8 vs the native CL10 of the other set that's specced at 1866
