Hi guys,

I'm planning to build a gaming PC with the Asus Z270H ROG STRIX gaming mobo and Intel's i5-7600K CPU.

I'm looking for some nice RAM and I'm thinking about the G.Skill Trident Z models.
I want 16 GB as a start.

However, I'm not sure at what speed they RAM should be? 2400? 3200? Can my MOBO and CPU support both?

I'm not confident with OC and heat management.

I'm looking forward to your answers, thanks in advance!

The motherboard can handle DDR4-3200, it might require your CPU to be overclocked a little but I don't think so. I'd recommend 2800 or more for gaming, only if you're playing at a refresh rate higher than 60Hz. Otherwise you won't really benefit from the extra speed and in such a case 2400 or 2666 Mhz will be perfectly fine.

Hi RCF,
Thanks for your answer.
When I look at the i5's specs it seems to me that 2400 MHz is the speed to go with.

Regarding refresh rate, does that depend on my monitor - for instance the 144 Hz gaming monitors?
Sorry for asking n00b questions.

With a 144 Hz monitor you should try and push for the equilavent amount of FPS in games, meaning 144 FPS. This will be easier to reach when the CPU and RAM are running at decent clock speeds, because high framerates really puts processing speed to the test.

You can basically ignore the i5's specs listing memory speed. It's basically irrelevant when you enable XMP on a Z170/Z270 series motherboard.

Hi again,
OK, and I enable XMP in the BIOS, right?
So to sum it up: You recommend me to go with 2400 MHz or 2666, but _can_ if I want to, go with 3200 MHz without any issues as long as XMP is enabled on the mobo?
