Picking the right RAM kit

[Nekrovar]

Hello,

I am building a system around the i5 6600k. I would like to use the ASRock Z170 Extreme6+ as my choice mobo. I plan to OC and want to choose the right RAM kit. I would like to shoot for an OC somewhere around 4.5GHz with that CPU.

I would like to have a 16gb kit, but am unsure of what speed is realistically achievable and also worth the money spent.

For example, if I buy a 16gb kit @ 3200MHz, is that a realistic and achievable speed with my chosen platform? I understand the basics of latency/timing, but do not want to buy something that I can't get the use out of.

Yes, you can run the memory at that speed, and in the right games/applications you will see a benefit from it. Furthermore that kit is reasonably priced for it's speed.

Another nice benefit of fast memory is it allows you a lot more options when overclocking. If you decide to use BCLK straps or anything similar in addition to changing the multiplier having a kit with a wide range of acceptable frequencies will make your life a lot easier and allow for a ton of ways to dial in and fine tune your machine for maximum performance.

I think it's a reasonable purchase. Your cooler on the other hand though, why not get a nice big air cooler?

Nice rig, the DRAM is fine, you can find the RJs in 3200 with even tighter CLs (they have sets at CL15 and CL14 now), I've had the set you list and it's good 😉

So that board has ASRock's XFast RAM. Is that the same thing as the XMP settings on other boards? I don't really want to mess too much, I just want to make sure I'm getting the speed at the CAS on the kit I want to buy.

The kit I have in that list is CL16. If I get the CL15 or CL14, is that going to be significant or change the 3200MHz speed on that mobo?

XMP allows you to easily set the DRAM up to run at spec. XFast DRAM is a utility program that is suppose to better manage your memory resources - see here:
