AM4 RAM?

[KSL]

I have a new AM4 Mobo and a Ryzen 1600. Tommorow I'm shopping for RAM and I'm looking at 3000mhz HyperX Predator kit. Many people claim that they have compatibiilty issues with their RAM on the new AM4 platform. What would happen if my RAM turned out to be incompatible? Would it simply be downclocked until the BIOS update? Would my PC even boot at all? Help a noob out, I need to get some RAM tommorow and I don't really know what's my next step. The MOBO is Gigabyte GA-AB350M- Gaming 3.3

It would boot, but you might not be able to reach 3000 MHz.

You can find the supported memory list here: http://www.gigabyte.com/Motherboard/GA-AB350M-Gaming-3-rev-10#support-doc

all DDR4 will work.*

 

 

 

*at 2133 MHz minimum.

To reiterate what @DocSwag said, you could boot, you just won't reach 3k mhz. Tbh it's kind of disappointing the Ryzen release is like this. Nothing's ever perfect when it first comes out, but this was a pretty major issue, and AMD still hasn't fully fixed it.

I think a lot of the reason is that the IMC in Ryzen wasn't actually designed by AMD, but rather they licensed it from a company that starts with an r and is something that "Ramsus" (can't remember the exact name).

Oh, they did? I thought AMD designed all of Ryzen. That's probably it then. Whatever it is, seems like the company AMD licensed the IMC from didn't do such a good job. That's RIP

Nope, just figured it out and Rambus is the company they licensed it from. 

 

I think Ian Cutress from Anandtech and one point said on Twitter that the IMC was licensed, and there are threads out there talking about how it's licensed. AMD probably just didn't have enough People and R&D to develop their own IMC (disadvantages of not being Intel ) so they had to license it.

 

Perhaps with Zen2 we'll see AMD's own IMC (among other improvements. Zen2 sounds exciting as there's a lot of known issues AMD can fix that might boost performance, including the CCX issues).

i donno, it's coming around, B-Die DDR4 is showing serious gains, and hynix chips are now gaining close to rated speeds. This IMC issue is spurring on a lot of competition and furious coding amongst the MB manufactures. It's a good test. I bet it's exciting in the lab.

Ah yeah, rip AMD. They don't have an unlimited budget like Intel, so they have to license stuff. That blows.

 

And hmm sounds exciting! Hopefully it'll fix all the problems Zen has rn.

It's probably a lot more than exciting haha

Buying RAM for Ryzen is utterly annoying. Those that work the best, will cost you over 200€ for 16GB.

And for others you can only pray that they will work.

small price to pay for faster fabric speeds.

But even if they don't work now they should in the near future with some updates right?

Hopefully. Not guaranteed.

We can't be 100% sure about that. And I don't understand exactly how everything works together and why Ryzen prefer B-die over E-die and Hynix memory ... It should be dooable but no1 know for sure.
