New Enthusiast Gaming Pc: Mobo + Ram Options

Good Evening Gentlemen,

It has been so long since my last visit here that I lost my old login information! Ha!

At any rate, I'm working on a hardware wishlist for a new top-end enthusiast gaming PC. I'm having a little difficulty finding the highest performance motherboard and RAM combination.

I originally had two orders of G.SKILL F4-3200C16Q-32GVK (for a total of 64GB of DDR4 3200 RAM) to go with the ASUS ROG RAMPAGE V EXTREME/U3.1 LGA 2011-v3 Intel X99. Unfortunately, despite the motherboard reportedly supporting both 64GB of RAM and DDR4 3200 RAM, these two options appear to be mutually exclusive. In other words, I can have either 64GB of RAM or DDR4 3200, but not both. The motherboard QVL only lists the DDR4 3200 RAM in 4GB capacities as supported. Since there are only a total of 8 RAM slots, that leaves a total available space of 8*4GB, or 32GB of DDR4 3200. The fastest supported RAM of the 8GB per stick variety is DDR4 2800.

If possible, I want both the 3200 speed (minimum) and the total RAM of 64GB in my new build. My filtered search results aren't producing any options though. Can anyone help me out?

Thanks a ton in advance! This community is the best!

Appear to be mutually exclusive based on what?

8 x DIMM, Max. 64GB, DDR4 3300(O.C.)/3000(O.C.)/2800(O.C.)/2666(O.C.)/2400(O.C.)/2133 MHz Non-ECC, Un-buffered Memory

QVL lists are useless. Any memory that passes basic compatibility check (DDR4 memory for DDR4 slot, memory speed supported by MB and processor) is OK. QVL listing or not makes no difference.
 
I talked to Asus support representative and they are the ones who told me the F4-3200C16Q-32GVK was not compatible because the memory was too large. Here's an excerpt from the support transcript,

Same model but the size is different.

Me 06:36:23 pm
So the size isn't compatible then?

16GB(4GB*4) is listed and 32GB (4 x 8GB) which you gave is not listed.
Yes you are correct.

Asus claims that board can support 64GB and then says it won't support 8*8GB :rolleyes:

So how that coard can support 64GB RAM then? Sounds like Asus support is stuck on useless QVL list. And once again, QVL lists are useless.
 
Based on the information they provided during that chat conversation, the motherboard does support 64GB and it also supports 3200 clock speeds, but not both at the same time. To achieve 64GB, the fastest clock speed you can have (according to their support and their QVL) is the 8GB sticks of 2800s. I don't know if it is a power or throughput limitation or what, but you are correct that their claims for supported hardware is ambiguous at best. It isn't a flat out lie, but based on what I've learned from Asus, it is very misleading.

I suspect that they only check QVL list and because they don't have 64GB 3200 memory there, they say it's not supported.

Then again they may be right but I still suspect that you can put 8 sticks of DDR4-3200 and get it work. Usually more sticks = less tight settings work, that's true.

Also, difference between DDR4-2800 and DDR4-3200 is very small. So this is not big deal. I suggest you buy that RAM kit and try how much memory clock you can get.
