Ram speed?

[MrXuha]

Hey everyone,
Built my first PC mid way through last year and had been gifted another stick of ram for Xmas and when checking if it was present in my bios after installing it (which it was) I saw that my ram speed was operating at 2400MHz. I'm currently using (2 x 8GB) Kingston HyperX Fury DDR4 2666MHz CL16 ram and am trying to figure out how to get it to run at 2666MHz as advertised? Have read the motherboard manual and it isn't of any help. If anyone here is familiar with the gigabyte bios and can help me out that would be great. Thanks for the help! 

CPU: i3 8100 (Upgrading to an i5 8400 soon)
MOBO: GIGABYTE AORUS B360 GAMING 3 ATX
RAM: Kingston HyperX Fury (2 x 8GB) DDR4 2666MHz CL16 
GPU: EVGA GeForce GTX 980 
PSU: Corsair RM550

You can either enable XMP profiles and set it to the one that brings it up to DDR4-2667 or just set the speed directly.

That is because your processor supports DDR4 memory only upto 2400MHz, so the system automatically reduces the ram speed to a speed compatible with your processor. Upgrading the processor will help! But there will be no noticeable difference at higher speeds because 2400 MHz is fast enough. Hope I could help!

Check supported ram type at Intel

Thank you @Decimator and @Mira Yurizaki ! I tried to set up the XMP profile but as stated from Decimator my processor can't support memory higher than 2400MHz. Will be looking to upgrade soon though!

I had an i7-6700, which according to Intel only "officially" supported up to DDR4-2133. However, the RAM I used was DDR4-2667 and I was able to set it to that speed. Though my motherboard had an option to  just set the RAM speed which I did.

 

It may not be your processor, but the motherboard.

I can't see that CPU not running 2666CL16.  What @Decimator said is mostly true, but CPU supported doesn't mean it will prevent you from running XMP speeds and it most likely can handle faster speeds.  I would spend some more time on it and bring more information back so folks can help get XMP running.

A locked CPU + a locked chipset means that memory speeds are limited to the official spec. Any XMP profiles that exceed the official spec will be reduced to spec, which is exactly what is happening here.

 

A Z370 board would allow the memory speed to be set to 2666Mhz (or higher since it's not locked).

Welp, I'm the guy that didn't read everything.  B360 is a bummer.
