A little help picking ram

[munin]

Hello.
I need to upgrade my ram and was hoping for some insight and help.
At the moment I am running:
16GB Corsair Vengeance lpx DDR4 2800 Mhz.
Asus x99 Deluxe.
Intel I7 5930k.

 

I am considering buying 
64Gb HyperX Fury   DDR4 2400Mhz (4x16) CL15. 
But are they compatible with my Mb and cpu?  I contacted the retailer and the answer I got was yes, and maybe.

The machine is primarily used for 3d rendering and fluid simulation so my current 16Gb's is a real hindrance at the moment.

Any help would be great.

If it says DDR4 then you're fine. Get whichever one you want, or the cheapest you can find. It's not going to make much difference.

I don't know why you'd go DOWN in clock speed. That board will OC memory capable of 3200 MHz so long as your unique processor can keep up.

Why not buy more 2800Mhz to go with what you have already? unless you only have like 4x4 sticks already? The LPX 3000Mhz RAM is about the sweet spot right now for pricing for 8GB sticks x2, if you have to change because of current low capacity, consider getting 8x8 instead for pricing maybe.

 

(edit) or 2 packs of these https://www.amazon.co.uk/Corsair-CMK32GX4M2B3000C15R-Vengeance-Performance-Desktop/dp/B01B1H2STG/ref=sr_1_13?ie=UTF8&qid=1474406595&sr=8-13&keywords=lpx%2Bvengeance&th=1

Thx for the reply guys.
I don't really want to go down I clock speed, but my budget only allows me to either buy 32gb 3200Mhz or 64Gb 2400Mhz.
In my use case I would benefit more from double the ram then the higher clock speed.

 

I allready have 4x4 2800 sticks and buying another kit that may or may not work with my old is not tempting. 

I would really like 128gb but thats way out of my price range.

well 2 sticks of 16GB 3200 MHz RAM is going to be a far better use to you than 4 sticks of 2400 MHz RAM.

 

the 32GB @ 3200MHz is going to give you the immediate boost you want, and will leave you room for that additional 32GB 3200MHz ram you'll eventually get.
