Morning everyone, or afternoon depending on where you're at in the world.

I'm curious as to what the differences are with the Ripjaws V and Trident Z RAM sticks provided by G.Skill.. I'm assuming that the Trident Z is of a higher quality then that of the Ripjaws V but is it like a 5% better or 10%, etc etc?..

Talking at the same frequency, same capacity... I know the Trident Z can reach higher capabilities but other then that anything else to note?

I think it primarily depends on the individual CPU, i.e. I run 4770Ks on both my Z87 and my Z97 Hero's, the one CPU on either mobo pretty much tops out at 4.6 (when running with the vCore at 1.25) regardless if I stick 2133, 2400, 2666 or 2800 DRAM (full load of 32GB) in there, dropping to 16GB it will run 4.7, the other CPU is pretty much the same though it runs 4.8 regardless of data rate w/32GB and 4.9 with the lower 16GB. Thatt's just the basic CPU and vCore, either can be increased slighty by adjustments to the MC (memory controller) and other voltage settings. It does seem that the amount plays in further than the actual data rate in that the MC is managing more. And you do see performance increases with the faster sticks, did...
So far as I can tell, the two are identical with the exception of the color and the heat spreaders. Both are just fashion items.

And... when you are dealing with Skylake there is no value in DDR4 ram that is faster than the default 1.2v ram.
Faster ram comes with higher cas numbers, negating the added speed.
And, faster ram needs 1.35v which will reduce your potential Overclock.

Thanks for the response I'm not too worried about having a lot of OC head room as the system I am building is just.. over kill.. And it won't need the extra boost with OC..

System Build:
I7-6700k
Sli Configured MSI 980 Ti 6G
Maximus VIII Hero Asus MB
5 x 1TB Samsung 850 Pro
EVGA 1000W Gold PSU
Windows 10
NZXT 850 Phantom
Trident Z or Ripjaws V depending if Trident Z comes to Canada in the next 2 weeks or not and if there is a big difference other than looks but I do like the Trident Z a lot more (and willing to spend a little bit extra for the looks...)
 
One possible other difference is the height of the heat spreaders.
G.skil is silent on the specs for both.
I imagine a query to them would resolve that as well as any technical differences.
If the height is more than 40mm, it may impact some of the larger air coolers.

As to air coolers, I found that only a modest air cooler is needed, even with a good overclock.
Look to Noctua for some of the best.

Ha... Oops accidentally picked this as the answer for my question.. I have a feeling (not sure why) but that the Ripjaws are a little larger then that of the Trident Z. and I need as small as possible as my air cooler is massive and I will probably change it out actually here for a different air cooler if it becomes a problem..

CPU air cooler in question is the Cooler Master V8 GTS

Could you please elaborate on this. Also, when you talk about reducing your potential overclock, are you referring to overclocking the RAM or the CPU?

I just got my Trident Z sticks in today so will be tested them head to head over the weekend, I expect the Trident Z will have more OC headroom (i.e. made with better binned memory ICs and the did with the Trident X in DDR3 (my Ripjaws V are 3000 the Trident Z set is 3200 so will be testing at both data rates as well as 2133, and there is a noticeable difference between 2133 and 3000, have already seen that in some minor testing on the Ripjaws V
 

I have found that running ram at higher than the stock voltage takes away some of the capability of the cpu to run at higher power profiles necessary to deliver a higher overclock. I just can't seem to oc as high on either haswell or Skylake with faster ram.
Moreover, faster ram does not really improve performance or fps significantly.
Here is one report that compares the effectiveness of faster ram on haswell:
http://www.anandtech.com/show/7364/memory-scaling-on-haswell
Higher ram speed is accompanied by higher cas numbers which reduce the effectiveness of higher speed.
A useful metric is to divide the speed by the cas number.
When you consider the higher cost of faster ram with fancy heat spreaders, it will usually be better to buy more ram than faster ram.

It does seem that the amount plays in further than the actual data rate in that the MC is managing more. And you do see performance increases with the faster sticks, did an article on sets of 2400 and compared performance at 2400 vs 1600 here:

http://www.tomshardware.com/reviews/dram-benchmark-fluctuations,4080.html

The numbers there were with basic settings, had then been fine tuned (i.e. timings of the DRAM both base and secondary the differences from going from 1600 to 2400 would have been even greater ;) )
