Hello, I purchased a kit of 16gb G. Skill Ripjaws V Series ddr4 rated at 2400 Mhz ram speed. Windows and bios is only showing 2133Mhz. How to I get this to run at 2400MHz? I've heard of XMP profiles but not to sure how to set it up. Also, if I change my ram speed do I need to change its voltage as well? Not sure how to do that either within my asrock bios. Will there even be a benefit too? I've read that if you up your memory speed your cas latency speeds will be slower. Is that true? Would a faster case latency speed be more beneficial than ram speed? Thanks.

Yes, it is supported but it does not mean it will boot up at that value.

All DDR4 will boot up as DDR4-2133. If your motherboard and CPU can support higher, enable XMP or manually set it. If you use a certified motherboard, XMP should work flawlessly. Once XMP is enabled, the motherboard can detect the performance values of the RAM (DDR4-2400) and automatically set/run them for you.

I have a core i5 7500 which supports ram speeds up to 2400MHz. For some reason, it defaulted to 2133MHz.

Well I see this.

It should default.
Are you seeing these speeds in the bios or through a program? Try CPUz.
Sometimes the bios shows something different.

The BIOS, task manager, and cpuz are all showing 2133 MHz.
