Deciding on a new set of RAM

Hey fellas, first time posting a thread here in a while. Looking to get some insight on a new RAM upgrade for my rig.

I have an Alienware Aurora R4 with a 3930K and stock 8GB of Dell 1600MHz garbage RAM currently, and I just saw these nice Corsair Platinum series RAM sets that I would like to upgrade to:

or 2 sets of these (since my rig is quad channel)

There is a fairly large gap in the price range, roughly ~ $90. Only difference being 1866MHz vs 2133MHz (and slightly varying timings due to the frequecies being different).

Now, my question being, is there really going to be a noticeable difference between these two frequencies for the extra $90? From my knowledge, I don't think there should be.. But I just want to get some opinions. I game quite often on the rig, but I don't really care for benchmarking/folding/etc. Just gaming and everyday tasks. Would the speed impact gaming performance to a noticeable level where its justifiable to spend the extra $90?

I am fairly knowledgeable with hardware, but I just want to get some extra thoughts on if its really worth it. Any advice would be appreciated.

Hey thanks for the reply.

Surprisingly, these look like the ones currently in my system that shipped from Dell factory, not sure if they are the exact same though, as they have different Dell Part Number stickers on them. But I have tried clocking them before, and I didn't really get anywhere, probably because of the crap Dell factory motherboard..I am really good at overclocking, but this board doesn't really have the best options for OC'ing in the BIOS.

Hell, even OC'ing my CPU has to be done on the Speedstep/Turbo Mode multipliers and not on the main multiplier, but that is a different thing entirely. lol.

I do know that my board does support up to 16GB of 1866/2133MHz or 32GB of 1600MHz or lower.

I will try clocking my set again, and if I can't get anywhere, I may spring for the 1866MHz kit if there is no noticeable difference. I mainly want to get 16GB of RAM with heatsinks instead of the current bare 8GB set.

Oh I have no doubt. Dell finds the cheapest way out on everything.

I am just now reading up on that Samsung set and they definitely have amazing potential. If it wasn't for my board, I would buy these in a heartbeat.

I would add fans to my case, if I had a place to mount them. lol. There is nowhere to mount any extra fans, not to mention the tight amount of room inside the case. The top area has no mounting holes, and the rear has a radiator. But I will ditch this case and mobo by November and get a nice Corsair case or something during Black Friday.

I guess I will just buy the 1866MHz kit for now, and see how it works out.

Thanks again for your help and advice!
