Note that he is talking about bclk OC and the max supported is still 2666MHz. What we need to see is if they can go above that at any point with 2x16GB. Ofc you can go with 4x8GB if that works for you and 32GB is all you'll need from it.
An asus employee said this recently, but I can't tell what board(s) he was referring to:

DigitalFoundry 1800X Review
Wichard!!! DDR4-3200! Frametimes!
The 7700K has frametimes all over the place depending on the game. I can understand why so many Ryzen users say "it feels so smooth".
Not sure the frame times are terrible, but in games where the 1800X and 7700K are putting out the same FPS, the 1800X frame time graph looks homogeneous.Isn't that the downside to hyperthreading? Higher framerates in games that use more threads, at the cost of terrible frametimes. Wonder how the 7600k fares.
Wait wait wait, FlareX uses BCLK for setting up 3200Mhz, doesn't it? And that board does not have bclk gen. So he for all intents and purposes did not even use the fastest setup. Whatever.DigitalFoundry 1800X Review

Yes. 5 years ago. But I buy hardware for 2017, not 2012.Isn't that the downside to hyperthreading? Higher framerates in games that use more threads, at the cost of terrible frametimes.
No, i mean that it means they are using 3200 multiplier instead of what G.Skill validated their sticks with (lower multiplier+BCLK increase). So it actually has worse subtimings than your run of the mill 3200 stick.Well yes. Without upping the BCLK it doesn't up the interconnect frequency, does it?
Modern HT does not use static partitioning of resources either, Ryzen does for few queues.There is no reason you should disable HT anymore like 5 years ago.
Not on MSVC software, tbh.
False dichotomy.
MSVC is kind of the whole compiler world in gamedev, ain't it.Like MSVC would be the whole world. Software is little bit broader term egt: Kaby Lake / Windows 7.
Agree with that and especially with MS being ass for decades now, but my point was that gamedev isn't the whole world and AMD is now targeting very many more segments with Zen architecture. There is always some optimizations depending on which hardware you build, test etc. the software. We will see some changes in MS scheduler, maybe different power saving schemes, more sophisticated thread scaling than just dummy video encoding and similar because of a new player/architecture available. From bigger perspective thanks to AMD there will be now more computing power available on the market than before. How to utilize that I call optimizing, some could say that it's normal development with slightly changed direction. From business perspective it's always hard to break in to a monopoly market. Intel is no exception, they have the resources and I'm pretty sure they have used their leverage whenever they have been able to do that.MSVC is kind of the whole compiler world in gamedev, ain't it.
Also Kaby Lake/Win7 relationship is more of a MS being asses.
Thats some surprising and interesting ram and os results.DigitalFoundry 1800X Review

Making judgement on thermal output based on temps? Come on.

My 1800x@4.0 with 5 case fans loads (without much of a video load) @229, so I can believe the 242, which is only 13 watts higher.Despite your tone, you raise an interesting question. Empirical data rules the day.
I hooked up my Kill-a-Watt, and based on the current power draw readings, I estimate that my EVGA P2 750W is sitting in one of the worst parts of its efficiency curve, giving it about an 88% efficiency. I tested two settings, comparing the package power readings of HWiNFO64 to the readings on the Kill-a-Watt adjusted for PSU efficiency. Bear in mind that board + VRMs will account for some discrepancy. I ran y-cruncher since it pushes hardware pretty damn hard.
3.6 GHz, max fans, no power saving, 1.35v vCore/DDR4-2133, 1.2v vDIMM:
Package Power @ load: ~95W
Package Power @ idle: ~17W
Kill-a-Watt @ load: ~229W
Kill-a-Watt @ idle: ~114W
Same as above but 4 GHz/DDR4-3200, 1.4v vDIMM
Package Power @ load: ~125W
Package Power @ idle: ~24W
Kill-a-Watt @ load: ~242W
Kill-a-Watt @ idle: ~110W (?!??!)
The suggested jump in package power @ load from 3.6 GHz to 4 GHz was ~30W, but the Kill-a-Watt showed a difference of only 18W between the two settings. The Tctl delta was ~20C (max Tctl @ 4 GHz was 86C, max @ 3.6 GHz was around 65C).
So I don't know what to make of that. Something is fishy here.
Also, HWiNFO64 records a CPU temp from the motherboard. According to that sensor, the chip never went past 42.5C @ 4 GHz. Even given the 20C offset for Tctl, that's a sizeable difference in readings between Tctl and the board's CPU temp sensor.
edit: Also, my Kill-a-Watt is reading insanely low power usage for the clockspeed and workload involved. y-cruncher is (for Ryzen) an AVX workload that pegs all cores, hard. It has produced the highest Tctl values of any program I've run to date on this admittedly-young system. Can it really only be using a total system power of 242W? The package power readings seem to be too high for the overclocked system . . .
Framerate =/= Frame time.
How do these chips fold/crunch (i.e. Boinc, etc)?
Can a 4GHz OC produce error free results 24/7 for months on end? (I guess long term is unknown yet since it hasn't been out that long)
Well, for at least 24 hours, thats all the longer I have had it up. It will be doing that 24/7/365 indefinitely, so ask me again in a few months.How do these chips fold/crunch (i.e. Boinc, etc)?

Edit: and mine is running 4.0 ghz on all cores, 24/7,
I haven't done any endurance testing yet. But I have done some HPC-style work with y-cruncher. It uses AVX, and I found that I had to up my LLC level to get it stable in AVX workloads running. Ditto for the latest Prime95.
Level 1 is boosting it to 1.4v @ full load. Level 3 held it at 1.35v. That's for 4 GHz, mind you.
Yes its an 1800x, I am on a cheap motherboard ($89) and the final build will be on a $200 one, so I haven;t done my sig yet. But 4.0 in this cheap mobo is pretty awesome ! And at least 2933 on the memory as well.Is your CPU an 1800x or another 8 core? Your sig doesn't currently show Ryzen anything.
