Would be nice to see how DDR4 compares with DDR3 - afterall you can buy mobos that support an i7-6700K and DDR3 - is DDR4 even worth getting (e.g. if you already have perfectly good DDR3 RAM and want to upgrade the CPU, do you get a DDR4 mobo and spend extra on new RAM or go for a DDR3 Skylake mobo and keep your old RAM)?

We have such an article in queue, I'll ask Kasia to put it up on two weeks.

Looks like just the kit for the person that wants 32GB's of fast DDR4. I wonder how it runs in X99 systems
I am running 2 sets of the RipJaw V series of these kit on my X99 system. I was able to run the memory at 3334 mhz at 1.35v, but the combination of that and having my cpu (5930K) running at 4.6 or 4.7 ghz was giving me stability issues with Aida64 (no issues with 3D Mark 11 tho).

Ultimately i ended up running my system at 4.5ghz cpu + 3ghz (16 18 18 38 2T). Now it runs stable on Aida64 even with all 3 overclocked gpu selected together in the stress test. Im pretty sure with some tweaking around some other voltage and timings i could pass the stress test at 3.2 or 3.3ghz on the memory, but i wasn't bothered with it for now.

yes its worth it, lets be clear, im on ddr2 right now so ill give you my perspective on it.

i used my 8gb ddr2 system like i had 16-24gb of ram, and everything constantly went to page... you know how expensive going higher than 8gb of ram on a ddr2 system is? till recently it was around 100$ a stick, and you needed 4, had i went ddr3 instead of a ddr2 motherboard to save some money, i could have 32gb of ram and literally never have to worry about ram for the next few years, but i went ddr2 to save some money.

i got lucky and found someone in china selling 4gb sticks of ddr2 for cheap as hell, so i got my 16gb, but i still hit 95% use fairly easily...

at some point ddr4 will out pace ddr3 with even the cheap models, and at some point the size of the ram will go up to the point you could turn it into a ram drive and still have ram to spare...

its worth going ddr4 just so you arent left behind...

also, lets not kid ourselvs, the last real reason to upgrade your computer was when you had a core2quad/duo or a phenom II 6x/4x/3x/2x and sandybridge came out, sense then there is been next to no reason to upgrade for a normal user, and with a ddr4 system, baring hardware failure, there will likely not be a reason to upgrade again for 6 years, so you may as well go ddr4

I'm confused by the selection of the 4 x 4GB (16GB) Vengeance LPX kit. Who buys these kits? I would think that if you're buying memory, you would buy the 2x8GB for later expansion to 32GB w/another 2x8GB. Especially if you're buying for the higher speeds, I would think you would want to have room for growth. Of course, if you're going higher-end, then you possibly would just buy the 4 x 8GB from the beginning.

I understand these are supposedly matched DIMMs for the best in compatibility, but I don't see a need for a 4 x 4GB kit.

Yessir! I switched to Z170 for DDR4 testing because the processors for my X99 platforms had difficulty supporting the higher data rates of newer modules.

It has already been proved, many times, that higher clocks than the base 400MHz (multiply by the DDR technology) don't have any advantage performance wise. Why do people still buy expensive OC'd modules is beyond me.

That's mostly true, as you can find here: http://www.anandtech.com/show/7364/memory-scaling-on-haswell
However I'm wondering if DDR4 makes any sense on Skylake vs DDR3 IF you already have DDR3 currently (I got voted down for some reason by "problematiq" and "eatmypie", but neither offered up an actual response to my question). RAM is expensive (especially if you already have a lot of it) and if I can get away with reusing my DDR3 RAM I would, as long as it doesn't cripple my overall system performance of course.

We have a small scheduling problem where we already have the DDR3 vs DDR4 article in queue, along with another memory review. The problem is that we only have one open slot next week, and the memory review has been in queue long enough that the company is asking uncomfortable questions.

Which is why I said two weeks :)
