ram What ram speed does Ryzen support?

[RandomWS]

Can someone tell me what ram speed does ryzen 7 1700 cpu supports?

I think it's 3400.

But right now 3400 will only work if you are using 2 ram sticks.

If you are using 4 sticks, it will work on 2400MHz, untill they fix that.

 

So you can buy/use 3400MHz, just note that if you will be using all 4 DIM slots, you should downlock to 2400MHz untill BIOS fix comes next month.

Okay, thanks!

How is that possiable? is it the motherboard that is blocking or how do you know what RAM speed is the limit? What speed does the 7700k or the 6700k support?

Not sure about i7 7700k limit, but it does support 3400MHz for sure.

Why is that happening with Ryzen ... no idea. Linus did address that problem in WAN show, and there are few other topic on this forum about that also.

And Ryzen already said that BIOS update will be avaliable in 1-2 months to fix that problem. Don't have any source of that, just read somewhere on this forum.

 

And I'm sure you won't even notice that difference between 2400MHz and 3400MHz. Also keep in mind that when you will lower it from 3400MHz to 2400MHz, you will be able to lower timings also. Lower timing ---> better performance. So overall performance won't be even noticable if you ask me.

Anyhow, that will be fixed soon.

I thought it was 2133 just like Intel?

The worst rumors says x4 2400MHz or 2x 3000MHz...
