Hello everyone,

Thank you for your time.

I'm searching for a motherboard that has support for 4000MHz XMP.

I play a lot of Fallout 4 and recent benchmarks seem to suggest 4000Mhz of RAM offering a lot of performance benefits to the game. Not so much on other games, but all I care about is Fallout 4.

I have found the odd one or two motherboards that support 4000MHz XMP, however my knowledge with motherboards is lacking. I found the, GA-Z170X Designare Intel Z170 Motherboard but I'm not sure if there are any other better motherboards with 4000MHz support.

I already own a 1080GTX but my current processor is a i5 3750k and RAM is Corsair Vengance 8GB 1600MHz DDR3.

I believe a i7 6700k and 16GB 4000MHz DDR4 along with my 1080GTX will get the most out of Fallout 4. I have had some thoughts of waiting for Kaby Lake 7700k but I don't know if I can wait.

I would like any thoughts and opinions in regrads to the motherboard, the 4000MHz ram and Kaby Lake

Thanks very much again,

- Dave

Personally, you will benefit more from 8->16gb RAM than you will from say 3000->4000mhz RAM. How much of an increase does 4000 show?

During my testing I'm only getting usage of 6GB of RAM. I noticed others online testing at 8GB of RAM and getting about 6GB usage. Correct me if I'm wrong but if the game is only using 6GB of RAM then 16GB won't have any effect, will it? I honestly don't have much knowledge about RAM. Only GPUs and CPUs really.

Anyway, I found a test online from Techspot.
Running, x2 980ti in SLI with a Skylake 6700k. They tested different games running at 1440p/Ultra with different RAM frequencies. All tests where at 8GB of DDR4 RAM. The frequencies where, 2133, 2400, 3000, 3600 and 4000.

All games recorded improvements in minimal and average framerates. Fallout 4 having the biggest leap.

2133 Min 41 Avg 49
2400 Min 50 Avg 54
3000 Min 53 Avg 58
3600 Min 61 Avg 65
4000 Min 63 Avg 67

3600 had the biggest increase. However a 22fps increase in minimal frames from 2133mhz to 4000mhz, from me, thats major for the amount I play Fallout 4. Considering I'm running 1600mhz which is even further below 2133mhz, I believe the increase I will see upgrade to a Skylake or Kabylake as well as 4000mhz would be amazing.

Anyway, let me know you thoughts.

That is very interesting and I will for sure take a look at that later when I am on the PC.
That is quite the increase, I would love to see what some £600 for 8gb corsair at I think 4400 would get it too haha
As far as I WAS aware there was not much difference in RAM speeds and whether or not that post was sponsored BS it's defiantly got the cogs turning and something I'm curious of because I am busy looking for some new ram too haha!

I also think that with more RAM the game will probably utilise it but you probably will not be able to achieve as big speeds, defiantly tty it and let me know
