I am building a new system and am trying to figure out which memory I should get. Below are the ones I am considering. They all are about the same price.

I will be using it for a lot of photo and video editing. Not worried too much about gaming or overclocking for the sport of it.
i7 4930k
Asus x79 Deluxe

I have been reading as much as I can but still am a little confused. Some questions:
Is it ok to use the 1.65v with the 4930 despite Intel's spec for 1.5? How about 1.6? I am not sure how concerned I should be about voltages.
Will using the faster sticks make the system less stable?
I have read that the Z series were designed for the x79. But does that mean I should use them over the x series? And what is different about them?
If I go with the sticks faster than 1866 will I have to do a lot of tweaking or will enabling xmp in the bios handle everything?

Thank you very much for your help.

First 1.65 is perfectly fine fine for DRAM 2133 and up and high performance 1866, 1.5-1.55 recommendation from Intel is for the CPU at stock and running their recommended 1600 sticks, higher freq requires higher voltage and is perfectly safe. As far as stability goes, the newer CPUs (Haswell and IB-E) like yours love fast DRAM and scale well to it, so stability is not a problem. The RipJaws Z were indeed aimed at the X79 and quad channel and the advanced timings are slightly tweaked towards that, the line went over well and expanded to pick up on the 1155 and the Z68 chipset. With your CPU up to 2133 should be nothing more than enable XMP and select profile 1, 2400 and higher may require a slight OC of the CPU.

Of those mentioned...

Out of those choices, I would go with this kit:

G.SKILL Trident X Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C8Q-32GTX)
Timing 8-9-9-24
Cas Latency 8
Voltage 1.6V

Due to the lower timings and latency.

You shouldn't need to tweak anything at all, since the MB will pick up the XMP profile, and automatically adjust the settings to match.

I would choose :

G.SKILL Ripjaws Z Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C9Q-32GZH
Timing 9-9-9-24
Cas Latency 9
Voltage 1.5V

Timing and latency are slightly worse that the 3rd set but we are talking about 1-2 millisecond plus for video editing 99% of the 'hard work' will be delivered to your CPU which by the way is very very good for a job like this. But the major reason why I choose this is that 1.5V voltage ram systems tend to be more stable than 1.6 or 1.65 V ones . I would sacrifice less that 1% speed in order to get stability. But thats just me :D

Xmp "should" fix everything no matter which kit you use, but if you don't think you need it to be as fast as possible it likely will be more stable at a slower speed such as the
G.SKILL Ripjaws Z Series 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 Kit. Still pretty dang fast, should be rock solid and is designed for your setup. I would think this may be your best option.

Of those mentioned I'd go the RJ Z or (not mentioned) the Tridents in 2400/10, followed by the RJ Zs in 2133/9 the Tridents in 2133/9 and then the RJ X in 2133/9

Thank you for your response. I have learned a great deal by reading your many posts on this site.

Could I ask you some further advice. Like I said I will be using this system for normal email, internet, dvr, some gaming etc. but want a top notch system for photo and video editing. I was planning on going with:
4930k
780 ti
32gb memory that you recommended
asus x79-deluxe

After ordering everything I have found out that the x79-deluxe is back ordered. And I can't find it anywhere. Amazon says late December.

I don't really want to pay 500 for the new Black coming out but I also don't want a board with older tech. I would also like to have as many 6gb sata's as possible.

Now I don't know what to do.

Do you have a recommendation of another x79 motherboard?

Should I change gears and go the z87 route. the 4770 only has 4 cores but I guess I could upgrade down the road?

Thank you for any thoughts you might have.

The Asus Rampage IV Extreme is between the X79 Deluxe and the Black as far as price goes, but is almost identical to the Black.

All X79's are going to have the same features (SATA and such) since those are controlled by the chipset.

going the Z87 route is still going to limit you to quad cores down the road.

For what you are doing, you shouldn't notice a difference between the quad core i7 and the 6 core x79's.
