Corsair's 32GB ddr4 2-dimm module advise?

[GregZarkodi]

Hi. First timer here.
Are there any significant or substantial differences between :

Corsair Vengeance LPX 32GB 2dimm set
(CMK32GX4M2B3000C15)

and

Corsair Dominator Platinum 32GB 2dimm set
(CMD32GX4M2A2666C15)

besides the obvious of factory standard o.c. ability of 3000 of the 1st and the 2666 of the 2nd?

The reason I'm choosing this setup, is to be able to add another set of 32gb (ofthe same dimms) in the near future.

The primary difference between those two are the timings and their corresponding frequencies. The Dominator Platinum series is geared more towards higher/stricter quality control and better binning of their chips but the 2666MHz you're seeing are with loose timings as opposed to the Vengeance LPX's 3000's similar timings at higher frequencies. The other difference that sets both kits apart are the aesthetics.

If you're going for a ram upgrade make sure you're getting the exact same kit to avoid any compatibility issues. Best wait out on purchase until you can drop all the money on 2x either of the above. Furthermore are you looking at an X99 or a Z170 platform to populate the slots?

Have a read through this article and some more here.

Thank you for the reply.
Indeed, I'm slowly building a desktop system based around a Z170 platform.

I am intrigued by the suggestion about purchasing two sets of memory, at the same time. After a lot of browsing and research, I stumbled many times upon similar suggestions. Obviously, the goal is to get the exact same batch.

What I do not understand is how the exact same product, with the same specifications and barcode may be different (and thus incompatible) to an exact another, of the 'same' line, specifications etc. Is it perhaps due to differences between product batches and/or manufacturing processes? From my POV, if this is true, it seems that two modules in the same package may be from different batches. Or maybe the vendor could sell me, not by his fault, negligeance or otherwise bad merchant practise, two physical packs/blisters belonging to different patches, just because it happened to have them mixed in his stock.

In the end, it seems that if such product inconstinsencies exist, the manufacturer should not be trusted...

Even getting two sets of the same at the same time offers no guarantees, better to get a 4 stick set (all in one package), yes it (4stick set) generally cost more than 2 2x sets, and there's a good reason, it takes more time testing sticks to find 4 individual sticks that will all play nice than it does to find 2 that will play. I did an article on 4x8GB sets of DRAM awhile back,

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

and two manufactures wanted in, but didn't have 4 stick sets, so each sent a pair of two stick packages, in neither instance would the manufacturers 2 sets play together out of the package, it took voltage adjustments to get them to play. I've also had instances where apair of identical sets bought at the same time wouldn't play at all.
