Got an i7 4770K with a sabertooth z87 board and Noctua NH d-14 cooler. I want to go with G Skill, either Ripjaw X, Ripjaw Z or Sniper due to height. What stock speed should I look for: 1600, 1866, 2133, 2400 for a photoshop CC and Lightroom rig that will give me rock solid stability, but get what I am looking for in better performance from the new processor? Confused as many say 1600 for stability but it seems that the i7 4770k can better use higher stated speed ram. Thanks.

When looking to pick RAM, don't look at the CPU, but the motherboard. According to the motherboard you are using (Sabertooth z87), I checked the MOBO specifications on http://www.asus.com/Motherboards/SABERTOOTH_Z87/#specifications, and you can use 1333, 1600, or 1866. The choice is yours: but the 1866 performs better.

i use the sniper 2133mhz CL11 ram and i have no problem so far (6month+ old) and they're overclocked to 2240 CL10 (that give 31gb/s bandwith in copy with a 3770k @ 4.83ghz)

The higher the Overclock will be, the slower the memory would run (for me 4.9ghz = 1866 or slower, 2133 don't pass and at 4.8ghz = 2133mhz = no problem) it's because the memory controller reach the minimum latency per cycle faster when you overclock it as it goes higher and higher with cpu speed...

taking in consideration that the IMC of the Haswell is better, i would go for 2400 or faster ram if you don't overclock, if you plan to overclock, the 2400 will be fine as you'll surely hit a wall if using a faster model and you'll then need to reduce the ram to 2400 anyway...

The Sabertooth Z87 QVL does go up to 2400. If I don't overclock the processor will using 2400 RAM give me stable performance?

Interesting that the G Skill site for the Asus Sabertooth z87 board is 2133 for the Ripjaws X, and only the Trident for 2400. Asus notes ram without series designation. I need the lower profile for the Noctua cooler, so probably will go with the Ripjaws X at 2133 instead of 2400 trident unless the 2400 Ripjaws X would work. Same rough cost, but not sure if not listed by both to work.

Be much happier with the Tridents, GSkill test as time permits (also if height is a problem or possible problem, the fins on the Tridents are removeable, a single small screw at each end and they slide right off), I'm running the 32GB set of 2400 with my IB build and they should be fine on the Sabertooth, have run the 2666 set on that mobo with a 4770K, I'm an Admin over at GSkill and helped a number of folks with the Sabertooths - HAVE NO IDEA why they list 1866 as tops for these mobos, they did the same on the Z77 version and it too ran 2400 fine with a 3570K

Thanks. I assume that since I am running the huge Noctua NH d-14 above the memory, taking off the fins off won't be a major issue as the two fans on the cooler as well as a 200mm case fan at the side should keep the memory cool enough. The tridents are the same cost as the x's. Thanks.

I plan to get 32gb of RAM but thought I might go 2 sticks for 16gb first to get up and running, then add 16gb of the same model soon. I see some recommend getting a factory package of all RAM at once. Does this have any benefit?

Yes, I don't recommend ever mixing packages of DRAM (nor does anyone who knows DRAM), it's sold in packages of different numbers of sticks for a few reasons, 1) it's been tested so that all sticks work together, with tolerances as tight as they are, out of 20 sticks off a production line, you may only fine a single group of 4 that will play nice at rated specs, or you might find 2 or three sets 2) XMP is the preferred way of setting sticks up in a system and the programming is done via the packaged set, i.e. a 2 stick set may have the same base timings as a 4 stick set (say 9-9-9-27), but when installed the 2 sticks may require an advanced timing for tRFC of 128 while the same in a four stick package will require the tRFC at 208....this is something I see in these forums all the time, people telling others, to just go ahead and add more sticks, which can be easy with low freq entry level sticks like 1066 and 1333, but once you get to 1600 and up, it gets progressively harder....on occasion the BIOS can adjust things to get them running, but seldom is it optimally, and there are very few around who are comfortable going into the advanced timings to set things up...and even then, the sticks may not want to play, so then you end up having to adjust the DRAM and/or the MC voltage, and again, few who are comfortable doing so.....What it can amount to is someone who buys two sets of 2 sticks to save $5-6 over buying a single 4 sticks package may end up spending hours trying to them to work, maybe paying postage and restocking fees, or making another trip to the store to exchange whatever....

I also read that don't mix packages for optimal performance & reliability. I wanted to wait on my kits & add more later, but remembered that is not a good idea. Thanks for reminding me of why. love my 2400's
