DDR4 memory for i5-6500 on Z170 board

[sharantk]

I'm looking for memory for my new build for gaming. But I'm confused to choose memory for it. I'm going for around 16GB memory. But there are a lot of it with different speed and latencies. I'm not going to overclock the CPU and also its a non-K one. Which memory should I need to choose?
1. Lower speed and lower latency
2. Medium speed and medium latency
3. Higher speed with higher latency

Motherboard supports upto 3400MHz(OC).
I'm not chosen the motherboard from my options, that's why I'm not giving the name of it.
Note: This is for a m-ITX build. Only two memory slots.
Interested in Corsair.

It has literally almost no effect on your gaming expierience
LinusTechTips once tested it and the difference between 800 Mhz and 3200Mhz was barely 1 Fps so just go for the Ram that looks best for you and is supported by your mainboard

Just make sure you are properly using dual channel (ie for 16gb, have 2 8gb dimms) and you're fine. The difference in gaming performance for different memory speeds is extremely minimal, to the point you would only notice in a benchmark. Also running higher frequency memory requires you to turn on XMP, and is technically "overclocking" its possible the i5 6500 will not even get along with the max frequency (3400mhz). Just get a good set of 2133 mhz, don't waste the time with a Z170 motherboard (you can save a few bucks) and be done with it.

Love those ITX builds.
What case will you use, and what graphics card?

On ram, one figure of merit is to divide the speed by the latency.
Higher is better.
Past that, it makes little difference. if you are using a discrete graphics card.
I would stick with stock 1.2v which will probably be 2400 speed.
Corsair is good, look for the lpx low profile versions.


Here is a report on ram speed scaling.

Past that, I would reconsider the non'K decision for a gamer.
A I5-6500@3.2 is $205 at newegg.
A i5-6600K@3.5 is $220.
Core speed is very important in some games, and for $15, you get some 10% better performance for a 6% price premium.
More importantly, you will have the option, using a Z170 motherboard to raise that multiplier some 25% more.
That is what the "K" chips are designed to do.
What Intel can not guarantee is how high.
As of 5/2016
What percent can get an overclock at a somewhat sane 1.40v Vcore.

I5-6600K
5.0 2%
4.9 11%
4.8 36%
4.7 64%
4.6 88%

Corsair Obsidian 250D

With a 6500 could look to 2400 and maybe even 2666, beyond that may be stretching it
