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

As i was first to report on this AMD need to address the issue of ensuring hdmi 2 ports are used on boards, specifically itx boards. I'm seeing hdmi 1 on boards so far and this is unacceptable when future apu's are going to be used.

The biostar itx board only has a 4 pin atx power connector, this isn't good news for current capability.
So i'm hoping manufacturers don't skimp in the areas that matter to me. Luckily i'm on a 4770k itx so i'm not missing out on anything, but i really want an r5 and itx under the tv.

Thats good and well but if you have a chip like mine where 3.9 requires 1.4v then you are going to need a good board. I wouldn't like to see the vrm heat at 1.4v on a low end b350 like the gigabyte AB350 gaming.

Well yes, fair enough. My approach would be different though as I wouldn't aiming for max. Rather I'd try to run the max I can with a set voltage. Something like the max I can take it at 1.2V for example even if that means 3.8GHz.

I would aim for higher speeds and something from the board manufacturers QVL.
2400 is gimping ryzen. Whilst 32gb cannot hit higher speeds yet there is every chance it will and you will be stuck at 2400. What will be your uses for this?

Normal desktop work , surfing ,Encoding and ripping and running virtual machines anything up to 4/5 at a time using windows 10 on them .

I really wish DigitalFoundry would expand their gaming suite. Battlefield 1, Doom, Civ 6, Watchdogs 2, F1, Mafia 3, and more newer games would really help shed light on performance as well.

I still wonder what's going on with Farcry and TombRaider though. Must be an engine limitation or something, because they really dislikes Ryzen.

Faster ram should help with the encoding as this speeds up the ccx interconnects. Just a though as you don't want to be rebuying ram down the road

I glad we're getting M.2 on the back, Whether I go Intewl or Ryzen as I suspect I will I want to go ITX.

Nah thats fair enough and thanks for pointing out so what should i be looking at something like 3000MHz or 3200MHz ?

I'd go with what you can afford really. 3200mhz seems to be the sweet spot but people are reporting massive increases with 3600 (assuming you can get that working)
If it was me I'd go with whatever the fastest stuff is on the motherboards QVL.
 
Is anyone running a Ryzen 1700/1700X/1800X with a 1080 or 1080Ti (Gaming Res - 3440x1440 Ideally) who streams? If so what is the CPU useage?

As i've been pulling some stats on my 6850K, as when using battlefield 1 or Battleground when streaming to (Via OBS using H.264) Twitch / YouTube my CPU usage seems to average around 50/60% useage with a few odd peaks around 80%. However, the 6850K has a 4300 Mhz overclock applied.

Thank you I'll take a look at them .

So even though most of the boards say DDR4 Memory Technology - 4 x DDR4 DIMM Slots - Supports DDR4 2667/2400/2133

Buy higher and try and get it to work or set it to run at 2667 ?

That is AMD's spec. Many have 3200 running now. Although the board plays a big part in this, I imagine others will catchup soon.

I just don't find reviewers who use old out of date games credible. why would you not do Doom and BF1? they are by far the most popular games of the day.

ppl get 3600mhz with timing tweaking, and Adata twitted a while back that they had OC sticks running at 4200mhz.
timings doesn't seem to matter as much as the speed when it comes to infinity fabric performance, we still need some extensive testing to get to the bottom of it, or wait for naples to be released at which point AMD will probably drop documentation for the infinity fabric.

I looked that adata reference up and it was 4222mhz, and that was 2 years ago for their xpg memory. Would be nice if we could get closer to that by now.
