Just get this TODAY. If you have a good motherboard, like the Taichi, it should work just fine.

Watch out he is talking 32GB not 16GB so there are more limitations.

Well, the only thing I read so far, was 2 sticks. 4 is a problem with high speed. I could be wrong, but nobody has said that yet that I have seen.

We did on the previous page but lets recap.
Ryzen prefers single sided and 16GB modules are DS so 2x16GB support is poor , even poorer than 4x8GB for now.

Hmm, maybe the ~4GHz ceiling is quite tightly connected to the GF's FinFET 14nm process as the upcoming Power9 has also 4GHz upper limit.

Well, I guess that we need somebody to try it on a Taichi, and let us know.

OK, I saw IEC on the previous page said he was already doing 2800 on 2x16, and ASUS said it was easier than 4x anything, so maybe he just needs to try 3200 ? or after the next bios update ? but what motherboard does he have ? The Taichi (from what I have read) is still the king, just impossible to get.

 

[KompuKare]

From what i remember, the performance does indeed drop with HT enabled, and not something that is specific to Ryzen.

Hardware.fr already covered this in their review
http://www.hardware.fr/articles/956-7/impact-smt-ht.html

So the answer is yes for game (they also did apps where both Intel and AMD only gained from HT/SMT), but Ryzen suffers more. The worst title for Ryzen was BF1 where it lost nearly 14%, while for the Intel the worst was Watchdogs 2 with a ~7% difference.

Just get this TODAY. If you have a good motherboard, like the Taichi, it should work just fine.

My main issue is that I don't want to spend $350 on RAM that might not be supported down the road at it's advertised speeds. I wish the Flare-X was just available already...

For 32GB I can go 2X 16 and roll the dice with double sided DIMMs being supported at higher frequencies sometime in the future and keep an open upgrade path to 64GB, OR I can get 4X8GB single sided DIMMs and run them at higher frequencies, but I've read the Ryzen memory controller isn't that strong so it might be slower than 2X16GB. The only situation I am aware of that has no problems is 2X8 GB, single sided DIMM Samsung B's. Theoretically I should be able to just buy another pair and get what I want, but it doesn't seem to work that way. Sorry if I am confusing anything, but this whole RAM thing has been holding me back for a while now.

I don't have any mobo at the moment - I was going to buy a cheaper one until I found out that only a handful of boards have external bclck generators (Asus CH6, Gigabyte Gaming K7, Taichi, Fatality Pro, and Gigabyte Gaming K5 (coming soon)). So it looks like I will be buying one of the flagship boards, probably the CH6 or K7 because AS ROCK is hard to get in Canada.

Thanks for everyone's help!

I disputed the Asus claim a few posts down.
The listed support so far is very limited for more than 2x8GB.
Ofc that is today and remains to be seen how things evolve

You got the 4 modules being slower bit wrong.
It's slower as in support for higher speeds is more limited but in this case so is 2x16GB.
4x8GB or 2x16GB at same clocks and timings are not gonna perform differently.
So keep an eye on support lists and get what fits your needs . Just in case, check if listed support is with bclk OC or not, better to be sure than sorry.
Ofc what mobo you get matters too so that's also a gamble early on.
The clock generator seems to only matter for bclk OC but it's unclear how wise it is to go that way so unless you are sure that's what you want, figure it out before rolling the dice.

Thanks for your reply.

So what happens if I find a 2X8 set that works at, say, 3200, CL14, 1T, and then I just buy two dual-channel kits of the same for 32GB? Will it fail to work until I scale back the performance? Ryzen doesn't do quad channel obviously but sees two, dual-channel setups, correct?

Sorry I am used to just buying fast RAM, setting an XMP profile and calling it a day. I appreciate all the help.

Having to relax settings a bit with more modules is pretty normal but it's worse with Ryzen at this point.
So yeah if you would buy another kit, you would have to clock all down quite a bit, unless support gets better.
Excluding bclk OC,maybe going that route could help but that's less than ideal.
As mentioned on the previous page, for the C6H Asus does list support for two 4x8GB CL16 kits but don't know if with bclk OC or not.
AMD promised that update in May so maybe it gets better then but i can't say how much better.Remains to be seen what mobos get that support, i suspect not all.

I've seen contradictory information on that in the OCN thread. I *had* a ASUS C6H which I have now confirmed is bricked (since the B350 replacement + everything else works). I think I could probably have gotten 3200 dual rank dual channel with BCLK OC, but who knows. I'm going to wait out the teething issues on RAM for the time being and build my system using a B350 motherboard I have on the way. Down the line I might replace with a X370 board depending on how things develop.

Then again, I might not, considering I can get similar OCs/performance on a $79.99 board with CL15 DDR4-2400 auto-XMP versus the $255 C6H + DDR4-3400 it replaced...

No idea about long-term longevity or stability at those clocks on a budget mobo. It's going to house a 1700 optimized for efficiency so I doubt it will matter.

 

[Puffnstuff]

They already DO run that way. I am at 2933 cl14, and there are at least 2 others here running 3200 cl14 on an 1800x@4 ghx

There's too much sorcery and pixie dust involved right to get it running consistently which is why I no longer am an early adopter of new platforms. I'll let you boys be the beta testers for everyone and later on I'll slip in after things have settled down.

Right, i thought i remembered seeing that somewhere but wasn't positive. So then we can say that intel has issues with their version of SMT (in games also). 6.5% in Watch Dogs. Is it OK to lose performance as long as you don't lose as much as the other guy?

Jeessh, I bought the memory (I have linked to many time before) I have a $89 motherboard I have linked to, I go into Ryzen master software, and tell it to run 1467, and 14,14,14,34 and apply. Thats not too hard for anybody to do I don't think..

With a 1T command rate?

Looks like the first of the game patches with Ryzen tweaks are starting to hit. Unknown yet what performance uplifts are in store:

Dota 2 Update - March 20th, 2017
- Fixed the display of particles in the portrait window.
- Fixed Shadow Fiend's Demon Eater (Arcana) steaming while in the river.
- Fixed Juggernaut's Bladeform Legacy - Origins style hero icons for pre-game and the courier button.
- Improved threading configuration for AMD Ryzen processors.
- Workshop: Increased head slot minimum budget for several heroes.

The perf increase for Dota2 should be huge. It was one of the games that was far, far below expected, similar to Doom, Watchdogs 2, and Deus Ex.

The correct comparison is with SMT enabled and core parking disabled for Ryzen, Hardware.fr state in this article that balanced power management and core parking are driver disabled in W10 for Intel CPUs...

Dans le doute, nous avons réalisé une installation "fraîche" de Windows 10 Anniversary Update sur les deux plateformes, et nous confirmons : sur Ryzen, le Core Parking est réglé à 10%, et sur un 6900K à 100%.

Il semble probable que Microsoft ait désactivé le Core Parking sur les dernières générations de processeurs Intel et qu'il n'ait pas encore fait cette modification pour le tout nouveau Ryzen.

Google translated :

In case of doubt, we realized a "fresh" installation of Windows 10 Anniversary Update on both platforms, and we confirm: on Ryzen, the Core Parking is set to 10%, and on a 6900K to 100%.

It seems likely Microsoft has deactivated the Core Parking on the latest generation of Intel processors and has not yet made this change for the brand new Ryzen.

 

[Markfw]

With a 1T command rate?

Yes, 1T. Mine is on my $89 motherboard at 2933. I still have not tried 3200, but the others I saw said they had no problem @ 3200.

Oh, and thats @100% load for 2 days now. (WCG distributed computing)

Appears to be Windows https://www.reddit.com/r/Amd/commen...ave_partially_solved/?st=j0i8fg64&sh=62e903c3
We do need folks with Ryzen to verify this.

Well.
Ran windows 10 update, nothing specific for Ryzen appeared.
Other than the cumulative update for Windows 10 (KB4015438) to bring it to 14393.969, there was nothing.
KB4015438 also appeared for for my AM3+ / FM2 PCs, so don't know how to get the "Ryzen Mar 16 update"

That cant be a very difficult patch for microsoft to implement, what is the hold up? Come on MS get the damn lead out.

 

[alexruiz]

That's likely the right one

I don't think it is.
It appeared also on my FM2 / AM3+ PCs, so not exclusive for Ryzen.

On the other thread, "Ryzen technical" the guys were talking about KB4013429. That one is not in the update history of my AM3 / FM2 PCs, so that might be.

 

[Markfw]

Download that patch directly here: https://www.windowslatest.com/2017/03/15/direct-download-links-kb3213986-2/

The number looks funny one the link, but open the page and look.
