Ram not hitting rated frequency

[IronCanuck]

I've just built a new pc. The ram is rated at 3600mhz however it's only achieving 1300mhz. I've enabled xmp so I'm not sure where the issue lies. The parts in question are as follows:

Ram: Corsair vengeance RGB Pro 3600mhz

MOBO: asrock x570 pro4

CPU: Ryzen 7 3700x

 

Any and all help appreciated.

Try enabling XMP and save and exit BIOS. 

Don't touch your keyboard and just let it sit, as it needs to train the memory.

 

Have you tried doing this already?

is your ram in slots 2 and 4?

Yes however I can try it again. Do I need to set the frequency as 3600 or leave it on auto?

That's correct, I followed the motherboard manufacturers guidance.

A set of memory has an XMP profile built in, so auto might just work.

But basically you turn on XMP, save & exit BIOS and just don't touch it, until you boot into Windows. Sometimes it needs to 'train' the memory.

 

Although to be honest, I have heard about people not reaching full speeds with Corsair memory on AMD systems.

I've done this and is boosted the frequency from 1300 to just under 1800, still a fast cry from 3600 though.

In short: If something like CPU-Z or Task Manager show 1800Mhz, it's running at 3600Mhz.

 

In long: Your memory runs at 1800Mhz, which is (millions) of ticks per second. Per tick it can do two transfers (which is why it is called DDR = Double Data Rate), so it is running at 3600MT/s (millions of transfers per second). For ease, or because they feel it's fair, manufacturers of memory/motherboards call this 'MT/s' unit 'Mhz', thus you have a 3600Mhz set.

CPU-Z reads it out the right way, thus 1800Mhz, which lines up with the 3600Mhz the manufacturer says.

Thank you so much, this has been very helpful. I did not know this. I appreciate your time and explanation!
