Question What's the maximum ram speed supported by my MOBO?

i7 8700

I wanna upgrade my 2133mhz 16gb ram to a higher speed and sell my old ram.

1 friend told me to buy a 3000mhz kit and enable XMP and it will work. the other said that the limit of the mobo is 2666mhz.



The mobo says it only supports ups to 2666mhz, but the other friend said that the whole point of XMP is to support higher speeds and 3000mhz will work with XMP.

which one is correct?

2666mhz is the limit for ram on your motherboard/cpu combination.

B360 chipset does not support ram OC. Z chipset boards like Z370, Z390 would support ram overclocking.

He said that that's the point of XMP. if i enable XMP it will support it.
I don't know what's the difference maybe because my MOBO supports XMP it will work?

Even with XMP - 2666mhz will still be the limit.
You can use 3000mhz ram, but it will run at 2666mhz (if that wasn't clear).

So why does my mobo supports XMP if it can't go past the maximum speed anyway?
Just trying to understand how things work

Ok - 3rd time...
2666mhz is ram limit on your board/cpu combo.
Going past 2666mhz requires ram overclocking. Your board doesn't support it.

XMP is just presets of ram config. If your board supports xmp, that just means, it can read those presets.
But it can not operate ram in those presets, because of lack of support for ram OC.

I hope, this clears it. Because I don't think, I can explain any better.

Ok. so I was going to buy this:
Corsair DDR 4 16G(8GX2) 3000 CL16


but this
HyperX Predator Black 16GB 2666MHz DDR4 CL13


should run better then on my setup. right? they both cost the same

Differences minimal.
Corsair ram at 2666mhz most likely would run with CL14.

Make sure, you get a kit with 2 modules (not single 16GB module). 2 modules are required for activating dual channel mode.
