Continued from the "AMD new horizon event" thread.

Please discuss and post any new information here regarding the upcoming AMD Ryzen CPUs and AM4 motherboards.

Thanks

i doubt your memory will boot up @3200 - because that's not official supportet

^^yeah its probably good for a kaby lake build.

Hmm where are you people getting this info from?
The AM4 Motherboards fully support pretty much any DDR4 speeds out there. It depends on Motherboard model really. Doesn't matter what CPU you use.

Boot up + OC does not matter. Only matters is if you want to install RAM that clearly is not supported by the Motherboard. Thats all you have to worry about.

Intel all do the same thing. So does basically every system.
Ahh lets see, install some 1866 RAM in my 990FX, ahh yes, boots up as 1333... yea no crap.
Enable XMP; done. Now all the spec'd settings are applied and active. WOW that was really hard wasn't it.

Dual Channel - Dual Rank - 4 DIMM: 1866
Dual Channel - Single Rank - 4 DIMM: 2133
Dual Channel - Dual Rank - 2 DIMM: 2400
Dual Channel - Single Rank - 2 DIMM: 2667

i don't want a board + memory that isn't booting at all. maybe you can just get a single DIMM working, boot up and then adjust the timings to get the board working with all 4 DIMMS at high speed.
imho we have to wait for BIOS updates and/or already tested RAM

[Squirrell]

Intel mobos reboot retrying with different memory settings until something works. But maybe not if you set XMP and don't leave the memory speed on auto. AMD mobos would almost certainly do the same thing I reckon.

AUTO is for default/first boot, or changing of RAM.
Once you POST, you enable XMP; it can't get any simpler.
Folks used to Laptops or PreBuilds simply do not understand any of this though.

Overall, you are mistaken with the RAM limits; SPD or Boot has nothing to do with supported.
The default will occur on boot; that is normal for ANY PC out there. You simply change it!

Just watched some well known folks on YouTube do some Ryzen builds; using 3000 and 3200 RAM, not problem; even with 4x 8GB installed

I'm doing a build later today, so I'll see how it goes.
I am seeing that all the ASUS offers for AM4 are buggy at the moment, they need BIOS fixes.
So glad I went with ASRock X370 Taichi

For the ones that i have watched none of them reached 3000Mhz they said it simply didnt boot. The closest to 3000 was around 2900 mark from gamers nexus i belive. Its probably something to be fixed later on but thats what it is right now.

[wah007]

@Bad-motha didn't you say you were going to wait a few weeks/months to buy it lol.

It's hard to resist

What Motherboard and RAM?
From what I saw, yes ASUS boards having this issue, could only do around 2666

This leaves Ryzen buyers in the unfortunate situation of trying to navigate something of a minefield when putting together their new systems. To play it safe, we'd recommend you stick with 16GB dual channel kits that don't run higher than 2666MHz or dual channel 32GB kits that don't exceed 2400MHz. Higher speed memory can and will cause boot-up issues.

Memory compatibility could also be a major hurdle to overcome since right now. It is both confusing and frustrating. For example I tried two different quad channel 1.35V 64GB DDR4-3200 kits and the system flat out refused to POST on two 370X motherboards from ASUS and Aorus. Even ASUS’ otherwise-flawless MemOK! feature failed to save the day. These hiccups may point towards some basic teething issues for a brand new platform or they could herald a very prickly situation for end users who are trying to piece together an AM4-based system. Either way, right now the best thing to do is stick to memory that features a JEDEC-approved frequency of 2666MHz or less.

Yep all asus boards im not sure about the others but as i said probably something to be fixed soon.

now what?

Yea the ASUS boards are flawed; we know this; they just need a BIOS update.

The ASUS Prime however, which is the cheapest ASUS X370 right now; had no issues that I saw; ran 2x 8GB 3666 @ 3200 (this was the max allowed right now; due to lack of bios refining and profiles to date) and also a 3000 kit, which did ok, but ran at 2933. Now this was simply due to the fact that it's taking Intel XMP profiles and translating it over to what is suitable; so yes there can be some issues there. All this needs is further BIOS tests and updates from the Board makers.

But you are stating it flat out wont work, which is just wrong.

And if you go out and buy say 3200 RAM and for the time being it has to run slower, so what. That will get addressed later.

[GTsimms]

I had issues with Corsair 3200 lpx 2x16 GB running over 2933 on ASUS Prime Z270 A (not on QVL list.) Which was also an issue at the corsair forums with Z170 reaching 3000 with the 2x8 kit. It posted fine with Gskill Trident Z 3200 quad 32 gb 14--14-14-34 at XMP 3200 on the Z270 on QVL list. So, if I can get it to 2933 on the ASUS Prime X370 Pro. I will be happy.

Yea at this point the issues for everything Ryzen is obvious; they rushed everything.
Even the Motherboard makers are saying they were sorely rushed and barely had time to get the BIOS out.

I could go into alot more; but I won't
Just sit this Ryzen idea on the shelf until we get the go-ahead from the Motherboard makers; cause that is a major part here and nothing is going to work properly/accurately if the BIOS is having issues.

[Black Mambo № 5]

There is like a gazillion RAM modules out there, its very hard for mobo manufacturers to test all those for compatibility, especially when you consider they got the micro-code 3 weeks before release, not even a month. Skylake, Haswell-E & Broadwell-E faced LITERALLY THE SAME issues with regards to mem-compatibility! :)

So far from what I've read in reviews & user experiences:

-- Gigabyte, AsRock = best compatibility, least issues. People hitting 3000MHz+ on their RAM in 2xDIMM config. (No idea about 4xDIMM).

-- ASUS, MSI = worst compatibility, lots of issues. People barely hitting 2933MHz on their RAM in 2xDIMM config. (No idea about 4xDIMM).

That doesn't mean ASUS MSI boards are dud, it simply means Gigabyte & AsRock pushed out BIOS updates that address memory compatibility issues much faster. Give it a week or two and it should normalize for every vendor. Becasue right now its all over the place!
Personally I was disappointed in MSI, coz I was eyeing the Xpower Titanium broad but at least I can wait until R% & R3 launch, by then the issues should be sorted out.

BTW, guys its probably and outlier, but this guy got his memory roasted by enabling XMP:

I'd say proceed with caution with memory OC'ing right now.

Edit = typos.

[GTsimms]

They need to look at and if memory is on QVL list this extends to Z170 and Z270 http://forum.corsair.com/v3/showthread.php?t=149795
