Using two pairs of 2x4gb. Will it work?

[_SomeOne_]

I'm looking to buy two pairs of Corsair CMY8GX3M2A2400C11 Vengeance Pro 8GB (2x4GB) DDR3 2400Mhz

I only need 16gb and want 2400mhz.. while also filling my 4 ram slots.
The only way i can see this happening is buying two of these sets.
I have had a look on the internet and most people say its absolutely fine.. while a selected few say you may have problems mixing ram even if its exactly the same.

Whats your take on the matter? Will it work?

It's fine, but you don't want to fill your RAM slots.

Why not?

nevermind i googled it.
Is it that much of a drop?

Okay.. i might go with 2x sticks rather than 4x..
edit nvm

Simple fact that there's no reason to fill all slots, and empty slots leaves room for upgrade later.

You could of explained that in your first post...

Just saying..

Hey pp, is it ok to have just one stick of 4gb DDR3, is it faster over 2x2gb?

It's fine but It will depend on the speeds.

If your 4gb ram is 1600mhz
And your 2gb is 1333mhz and other 2gb is 1600mhz then it will use 1333mhz, so it will be slower than having one 1600mhz stick.

You won't notice a difference though.. Either way, it only makes a difference in total ram size really.

Most people don't listen anyways so I don't make long drawn out posts initially. If they ask I'll answer.

2 sticks will give you dual channel, but you won't see the difference.

another question..
I bought this Vengeance® Pro Series — 8GB (2 x 4GB) DDR3 DRAM 2400MHz C11 Memory Kit (CMY8GX3M2A2400C11)

I've set it to XMP on my MOBO (msi z97 xpower) It's running at 2400Mhz, 11-13-13-31 latency at 1.65V
I've stress tested my PC for over 24hours.. ram and CPU and it was perfectly fine. After the stress test, using the pc normally, web browsing, idling, gaming.. it sometimes just shuts down and says that the overclock was unsuccessful on a black screen... sometimes even before I've typed in my windows pin to get to the desktop.

Would you say its faulty ram?.. or would I have to set the latency manually?

My CPU, i7 4790k is overclocked to 4.7ghz at 1.288 volts and that seems very stable. I haven't had a blue screen during any stress tests or while using the PC normally.
If it was an unstable CPU OC.. it wouldn't show the black screen with OC unsuccessful would it? It would only be a blue screen right?
