DDR4 RAM - 2400 Mhz or 2666 Mhz or 2800 Mhz For Heavy Duty Video Encoding On i7-5930K Rig

So just pulled the trigger on an i7-5930K System that will be used for both gaming and some intense video encoding/authoring. Probably going to have 2 or 3 instances of programs like Multi-AVCHD running at the same time .

Haven't purchased the RAM yet because I wasn't sure which to get.

(4x4GB) DDR4 2400MHz CL15 ($299)
(4x4GB) DDR4 2666MHz CL15 ($379)
(4x4GB) DDR4 2800MHz CL16 ($429)

Would going for the 2800 Mhz be overkill ?


Full System Below

• i7-5930K
  Asus X99 Deluxe
  Corsair H105 Cooler
  EVGA Supernova 1000W Gold PSU
  Cool Master Storm Trooper Full Tower With Window
  2 x Club 3D Radeon R9 270 Crossfire
  SX900 256Gb SSD

And please keep in mind the 2 R9 270's will be replaced by three GTX 970's or 980's when they become available next month.

Get 2x8GB and the 2400 MHz.
I can tell you that there is practially no difference between 1333 and 2400 MHz DDR3 RAM,so i assume that it is the same with DDR4.So you don't have to worry about that.
Again,2x8GB(so you can add another 2x8GB i the future,otehrwise you will have to buy a completely new kit of 4x8GB if you go with the 4x4GB option) and 2400 MHz RAM.
All the best.

That CPU is quad channel memory. You want the 4x kit. There are 8 slots in that motherboard.

He can do that.
Or go with the 2x8GB so he can have up to 64 GB (8x8GB),rather then having 32GB of 8x4GB and then having to buy a whole new kit of 8x8GB.(If that is ever needed,ofc)
He can use that 64GB.For instance,he can get a RAM disk,which is like 5 times the speed of an SSD,and use 40 out of 64GB.
I'm not saying that getting 4x4GB of RAM is bad,it's just that if he even needed more,he will be able to have 32GB,rather than getting 2x8GB now and having up to 64GB,completely filiing the mobo and fully using the max RAM allowed.

To get maximum benefit from that CPU, if you are going to spend the premium for DDR4 and X99 motherboard, you want a quad channel RAM kit. Dual channel RAM is halving your RAM bandwidth. I wouldn't recommend a dual channel implementation, because that isn't how Intel designed that chip.

Thanks guys. So I should go for the 4x4Gb 2400Mhz (4x8Gb if I had the money to spare) because there really won't be a noticeable difference going to the $429 2800Mhz.

 

[LukaBoki]

Yes,that is exactly what you should do.

 

[kanewolf]

Agreed.

 

[esox]

Thanks again guys, you just saved me a few bucks I could put towards the 980's when they come out.

 

[LukaBoki]

Of course,that is a better idea.
Have fun with your new RAM.
