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

Looks like DPD will come just as I need to leave the house to go install my old streaming 6700k setup in a friends PC.

Ah well, I'll most likely post my temps and stuff Sunday night.

I agree on that. Especially those using the Asus CH6 Hero show completely different perf compared to Gigabyte motherboards, and the difference is big.
(pointing at Joker's video at 1080p with the GTX1080 also).

Also we do not know how many of them had patched with the CH6 Hero with last weekends BIOS, which resolved many issues.

And we have just B350 Tomahawk, for less than half the money the CH6 Hero not only overclocking better, not only supporting better ram timings and speeds, but requiring less power to overclock the CPUs!!!! Even with the stock Wraith cooler, or just simply the Notcua NH-U12S

Looks like time to completely ignore the reviewers and wait for the guys at overclockers to post their result.

71 c totally fine push it further.

How high can the temps on these safely go?

 

[Scramz]

71 c totally fine push it further.

Roger, I try now.

Ok this just got very interesting https://www.facebook.com/theoverclo...46028454.301569.72682703453/10155035829263454

Some games like threads more than Mhz.

 

[8 Pack]

Ofcourse which reviewer can beat the Pack.. Makes sense to wait for me/ us. They are all wanting to be first no matter what level of testing they find acceptable to themselves. I am sure Twst has tested more than any reviewer the last few weeks for example.

Well that's a Prime B350-A matx board ordered for delivery tomorrow and another crosshair on back order for a few weeks time hopefully it will work this time

 

[harney]

So here is my Cinebench results:

R7 1700
MSI B350 Tomahank
16GB Crucial 2400Mhz DDR4
Notcua NH-U12S
EDIT: BIOS V1.0
Power = Performance mode but sure no different with balance.

3.6 @ 1.104v

Spoiler: 3.6 @ 1.104v

3.7Ghz @ 1.176v

Spoiler: 3.7Ghz @ 1.176v

3.8Ghz @ 1.224v

Spoiler: 3.8Ghz @ 1.224v

3.9Ghz @ 1.304v

Spoiler: 3.9Ghz @ 1.304v

4Ghz nees over 1.4v and the heat output rockets at 1.4v so on air I am not pushing that. Topped at 71c but I am not sure what these CPU's can take and wouldn't want to brick it.

Just to add, 3.65Ghz @ Stock volts Real Bench H254 5 runs with ease.

Spoiler: 3.65Ghz @ Stock

What should I bench now?

Thx do you have a laser temp gun scrams if so would love to know the temp of the cpu vrms while on load...

 

[Davedree]

i think once he has install the os on the tv should be fine once it boots into windows but yeah strange one not to see the bios / post

£250 board and no dual bios, terrible.

Man, I'm so darn conservative compared to you all. I could hit 4.3Ghz on my 5820K, but didn't like it touching over 70 degrees under 100%.
So settled at 4Ghz, with it peaking at a max of 60 degrees with 1-2 cores.

The guy has stated that he patched his Asus CH6 Hero with the last BIOS, which includes the last microcode (CPU firmware upgrade) by AMD.
And the performance boost was big, compared to the initial review he did, even if still using the same 2133 memory. That microcode resolved an issue between the CPU and the IMC.

In addition, running Windows on balanced mode prevents Ryzen from switching clockspeeds and voltages any faster than 30ms.
If the windows are set on High performance, it allows it do go into 1ms, full speed, switching. Imagine how faster the CPU->GPU communication is when the entire CPU is allowed to be 30 TIMES more responsive with boosting?

Which shows, all issues are software related.

Your not going to get any disagreement from me I might change it to the gigabyte board I have always used asus though

Glad to hear this ....This M$ power management has always been an issue for any cpu speed-stepping ect great for power saving but usually creates high DPC ...

Lets hope M$ refine it better for th Ryzen chips

Agree that is terrible

 

[Hotwired]

Looking forward to the reviews when all the bugs are fixed.

 

[LtMatt]

Not sure if someone has already posted this, but 1700 Ryzen delivering a much smoother gaming experience than the 7700K @5Ghz.

Amd rushed to get their Avfs setup, like we all agree, they should have delayed a couple of months to get everything setup, tested and qualified. Considering they had this syatem in carrizo and bristol ridge the performance plan bug should have been spotted. Now you may think i'm over critical but look at the bugs, look at the lack of motherboards, look at thr bios patches, no hdmi2 on the boards. It's a last minute rush job.

On a positive note, scramz is having a cracking time

 

[Ade74]

I have not used the stock cooler. I would prob add 5-10c on this cooler for them. Temps are really good, 50s and 60s.

Please can you say which cooler are you using? Also which memory?

I think he mentioned a few pages back, Noctua U12S
