Good evening everyone:)


I've just received a good deal to purchase this ram CORSAIR Vengeance Pro 16GB (2 x 8GB) the deal is whether I pick 1866 or 2400 will be the same price!! So please advice me which one should I go with?? I am planing on overclocking my i7 4790k cpu to the highest available clock speed. This my mobo type GIGABYTE GA-G1.Sniper Z97 Also my pc is just for Flight simulator X and BF4.

With 1866, you will get 1.5v and a lower cas number. With 2400 you will be at 1.65v and a higher cas number.
The actual app performance will be the same. I bought 2400 and wish I had not.
When I overclock, and run the ram at higher 2400 speed, it seems that the cpu heats up faster and limits the overclock.

----get the 1866----------

RAM speeds don't differ much on performance honestly, i'd aim for a 'plug and play' version of ram such as Kingston HyperX Fury i believe its called just so you know your getting the right speeds and such without having to set them yourself. But if you can set speeds and they are same price, why not aim higher. you won't see a huge benefit. And 8 GB should be enough for BF4 and Flight Simulator X.

Even then you still don't notice much of a difference, like between quality and poor quality, i grew up with poor quality everything, and had poor quality ram yet did i ever know it was poor quality. But yeah those are good suggestions, and like i said look for plug and play if you can, its easier, you get what you pay for without having to change anything. Great for beginners such as myself.

O i know people always get crazy with overclocking ram its mostly poitless 1600mhz is all u need for gaming but my mobo supports 1866mhz without an overclock i believe his does too so you might as well get the 1866mhz ram.

It's not like an Overclock like my standard settings on my Kingston HyperX Beast Series are like 1769Mhz or something stupid, i don't know how to actually find the XMP profile and insert that to get the Actual 2400MHz or what ever, i don't really need the 2400Mhz, it's just why pay for High performance RAM and use it to 3/4 of its Recommended Performance.

Like its 2400MHz ram but you have to manually set it to that is what i'm getting at.

Should be simply enable XMP and select profile....won't notice a lot of difference in gaming (a few FPS with the higher freq) but if you really use your rig (multi-task, video, imaging, CAD, VMs, that type of stuff) the higher freq DRAM will shine

Hey, you guys have crazy info here, I hope to be doing some editing soon, could any of you point me toward some benchmarks that demonstrate the increased performance? Thanks

Here is one:

The general conclusion is more ram is better than faster ram.
If your will be overclocking i7-4790K then the faster 1.65v ram may generate enough cpu heat to reduce your maximum overclock a bit negating any benefit of faster.
My suggestion is to buy the biggest kit of ddr3 1.5v that you motherboard can handle. That will be most likely no faster than 1866.
