*** AMD "Zen" thread (inc AM4/APU discussion) ***

Exactly Sir, which is technically overclocking ;)

It is pretty insane if you think about it.
Consider that many pages back I had posted the power consumption benchmark on handbreak.
A 4.2Ghz 1800X was consuming much less power than a 7700K at 5Ghz or even stock speeds!!!! However the 1800X has twice the grunt computing power to do the task!!!!!!!!
 
No one can deny Ryzen has a massive advantage in power consumption for a serious desktop processor.

Not exactly high on priorities since that's more to do with overhead costs and not raw performance but could mean good things for AMD when it comes to cramming more cores into a CPU and still getting good per core performance.

AMD execs dream of delivering Naples chips to the Google & Facebook datacentres by the truckload

I would love to see ryzen vs intel i7 7700k in gaming benchmarks using crossfire rx 480s/fury X and nvidia sli using 1080 or better while also doing memory overclocks on the ddr4 as ryzen seems to love those. Considering there has been a few screenshots floating around showing 7700k being pushed the near 100% using 1 gpu i wonder how the results would look using 2. ohh and let it be 1080p and 1440p.

Not very good given how naff crossfire and sli support currently is compared to single card.
 
So despite PCper's article on the Windows 10 Scheduler handling Ryzen correctly, they then test it more by trying to make Windows 10 stick to a single CCX.
What do they find? The Scheduler doesn't do what it's told to, and starts putting load on the second CCX when it shouldn't.

Talking from experience or are you repeating what other people claim/repeats? its a genuine question btw and i mean no offense.

I never liked Allyn. The only thing he really seems to know about is storage yet he always has a "professional" opinion about every other sort of tech which often seems way off. Josh Walrath is the guy to listen to if you want to know what is what with AMD in general.

Couple of things:

1. Temperature readings on 0902 and pre 5803. We tweaked it a bit too far and will be reversed in future updates, you can manually go back to stock/5803 behavior by going to Tweaker's paradise and set Sense MI skew = Enabled and Sense MI offset = 272 (0902 setting when overclocked is 283). Reading too low can affect your DRAM stability, so if your system is reading less than 30*C I suggest you set it.

2. DRAM settings, we changed to 2T when 2666 or higher ratio is used because of compability and helping some sticks work on the board. Unfortunately we can't set it dynamically or have an option for it until AMD gives us an update. I think overall it should be better for all, if you want to keep 1T you can use 2400 or lower DRAM Ratio + increase REFCLK (140-145 with 2400 DRAM Ratio is a sweet spot).

3. We're aware fan control has a lot of issues at the moment, I'll let you know when we have a fix for it.

Let me know if there's anything else serious that I missed, you guys are busy

We haven't seen many USB issues when pushing REFCLK except when going 145MHz+, perhaps you could try different USB ports from CPU or Promontory?
2x16GB DS most likely with future BIOS updates.
The source is credible. The option would have been to not have any boards at launch, don't think that would have made anyone happier.

Yup, Windows 10 is scheduling across the CCX's willy nilly. More and more of this coming out all the time. :/
