I, more or less, have the same build.  I had the 1080, and recently upgraded to the Reference 1080ti.  After getting the 1080ti, I'm glad I have the 6700-nonK w/ air cooling.  The case is so compact that you are only getting one liquid cooler in there.  Therefore, had I wanted to put a hybrid cooler on the GPU, I wouldn't have been able w/ the 6700K, and liquid cooler. 

Mine came w/ 1x8GB of memory (*Samsung) on purchase, and it had no XMP profile as it was 2133Mhz.  Alienware states (*in the manual found in, "Support") that the R5 can have up to 16GB @ 2400Mhz, OR 64GB @ 2133Mhz.  I'm not sure that's entirely accurate in that I think they may have said that for, "Safety" when I believe it can do, at least, 4x8GB DDR4 @ 2400Mhz.

I do not believe it's (*Mobo) capable of recognizing quad channel configurations, but is dual channel capable.  A free, ad free software to show you this information is CPU-Z.  It will display their, "Rank".  I have 4x8GB DDR4 Crucial Ballistix @ 2400 modules that would be recognized as quad channel if on a Z99 motherboard, but our R5 is Z71 (*I think that's the number).  As of now, I believe quad channel has proven little to no actual performance increase vs Dual Channel.

If the modules don't have heatsinks, then my guess they are stock 2133Mhz, and XMP 2400Mhz.  Meaning, they aren't, "Sporty" they are the modules you'd buy w/ a stock speed of 2133Mhz, and overclock to achiever the 2400Mhz, which I'd suggest you try. 

Perhaps you might consider adding your own heatsinks later on.  The company Arctic makes some quality / inexpensive heat sinks for memory. 

1. Should this model have the XMP memory fitted.

2. I'd also like to be able to confirm that the RAM is Quad-Channel.

3. Is there a utility which can tell me this info?

4. If there is then what details should I be looking for?

5. When ordering I saw that it came with something called an Oculus Place mat.

6.  is it possible to set the colours in AlienFX to change randomly on their own?

Well, the other users certainly did a good job of answering your questions. However, I have a bit to add, so I'll just answer them all my way.

1. It can, but is not required. That is only for Over-Clocking which you do not need to do (system is way-fast already).

2. No. That CPU with Intel z170 chipset would be Dual-Channel. This is assuming you have TWO exactly matched DIMMs in the proper slots (installed in pairs).

3. Yes. I use CPUID's software utility called CPU-Z

4. In CPU-Z utility, Memory tab, Channel # should say "Dual".   

Do not to confuse Channels (Dual/Single) with Ranks (on SPD tab). For example, the memory on a DPN: 5H5PW DIMM is configured in 1 Rank, while the memory on DPN: RGM6C is in 2 Ranks. This has nothing to do with the Channel Mode the Memory Bank as a whole is operating in. Single Ranked memory can operate in the faster Dual-Channel mode with no problems or speed decrease.

5. This sounds like a Dell Outlet purchase (or just non-new). I suggest you contact the business that sold it to you about any missing accessories. I will say that my new Aurora-R6 did not come with anything like that.

6. Not that I know of, but it would be cool. I always thought it would be cool if it responded to music or voice levels. Actually, I think there was a music plug-in for something like that (at one point years ago) but I never had much luck with it.

I would not worry about heat-sinks on DIMMs. If they needed to be on there, they would have installed them already (when they manufactured the DIMMs). Plus, they are at the top (near the top fan) and heat rises. You are good.

Back in the days of DDR3, ram speeds were much slower so Intel built some chipsets with more "lanes" or channels. There was dual, tri-channel, and even quad-channel (I think on x99 chipset).
 
With DDR4, even the single-channel speed is like double what it used to be (like 6 years ago). DDR4, in dual-channel at around 2100-2400mhz, and that chipset is a nice match for that CPU. In fact, it's so fast in single-channel, so people question it:

And that's just DDR3 ... you should have DDR4 !

Hey guys.

I've been downloading a game but I have a very slow broadband connection and it's consuming all my bandwidth so my emails weren't coming through.

WOW. I didn't realise I had 3 replies. Thanks so much everyone for taking the time to provide assistance. I'm really very grateful. This is obviously a very good forum.It's nice to know that there are people like yourselves here who are willing to help a newbie. Thanks again. 

OK, so I'm not so concerned now about my rig not having the XMP RAM. I'm a little disappointed that my RAM sticks do not have heat sinks on them though. When I purchased this PC and selected the RAM the picture clearly showed the RAM with the heat sinks on. A bit of false advertisement there me thinks.  But as you say I could always buy some heat sinks and fit them myself. I have enough experience working with hardware to do the job properly without damaging anything.

Whether I should be or not  I am though very disappointed that DELL say it's quad channel memory and the chipset doesn't even support it. Am I missing something here? Surely if they say it's quad channel memory then it should work as quad channel memory? (btw my RAM is 4 x 8GB 2133). I don't really understand why this quad channel memory is sold when it's not supported by the mobo. Anyway... I don't fully understand memory speeds. If the mobo supported quad channel memory would it be any better or does it just sound better?

Thanks again to you all.

Oh.. i forgot. Yes the Oculus Place mat is actually a download. That's what DELL said anyway. I assume it's software for if you buy the Oculus gear. My rig is Oculus ready but I couldn't afford the gear. Hopefully I'll be able to save up and buy some soon. I'd love to try out VR.  

So how would you guys rank this PC against the best of Alienware PC's with factory default hardware? LOL... ure going to break my heart and say it's at the low end aren't you?   

I ran CPU-Z and it says that the Maximum Supported Memory Clock: 1066.7 MHz. Do I assume correctly that as it's dual channel memory it is the 2133 memory that is installed? And yes it says it's DDR4 memory.

Aurora R5 Desktop PC
Intel i7-6700 (air fan cooled)

32gb RAM (16gb x2 in Dual Channel)

512gb SSD (SK Hynix PC300 M.2 slot 2280 PCIe/NVMe)

GeForce GTX-1080 8GB Founders Edition GPU

Power Supply 550w

Sounds pretty nice to me.

Might be faster (FPS in games) than mine, since I just got the GTX-1070.

Thanks. It was £1325 after all the discounts so I'm pretty happy.    The PSU is the 550w Dell one. But it's not the K CPU.  

Updated. Yeah, I'm big on liquid-cooling and large over-sized power-supplies myself.

Is that a SATA SSD or M.2 PCIe/NVMe ?

That is correct.

But I think it's the DDR part that does that (Dual Data Rate ... IIRC).

 lol... maybe I'll be able to upgrade in the near future.

The details I got from HWinfo64 for the SSD is: Drive Model: PC300 NVMe SK hynix 512GB. It was listed under SATA/ATAPI. I'm not sure it is SATA though. Is there any other way of telling for sure or will HWinfo be correct? 

Updated. NVMe drives are really fast.

$1700 USD sounds about right for that config. Add 4 or 5 upgrades at around $100 each and you end-up at $2200 USD (which is what I paid for my Aurora-R6).

Should give you many years of service.
