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

Ha :p Thermalright are sending me the AM4 upgrade for free along with a couple of fans that I've paid for. I have a feeling that some of the parts weren't quite right. The AM3 holes on the backplate didn't match up with the holes on the top mounting plate for example. So I'll see if it's any better when the parts turn up.
I'd really like LGM to work. It could be perfect in terms of performance, general dimensions, looks and value. Please let us know on here how you get on with the new kit (and @me if you remember to!)
 
To be honest what is really needed is a reviewer with a good clocking chip testing in various motherboards, in order to see if any of them bottleneck that CPU. If not, then it doesn't matter which board you buy, from an overclocking perspective anyway. RAM testing would need to be done too though.

I will try this kinda thing next week. I did something similar for z270.

Memory issues are bios related. Cpu microcode and such.
 
I caved in :( Bought the gigabyte gaming 3 along with 1700 to go with some 16gb corsair lpx 3000mhz ram I bought previously.

should make for an interesting weekend though. Already ran some tests on my current setup for comparisons. will report here with findings.
 
what does it mean when it says 6+4 or 7+1, ignoring the quality of the components, how could that impact overclocking? At the moment im looking at b350 boards as i have no use for multi gpu setups and to pair it with a 1700 fror my 1440p ultrawide. From the looks of it, at higher refresh rates, more performance would come from higher clocked, ram. So how would the VRM's affect the ability to both overclock the cpu and ram, as it seems that people are struggling to run their ram at their rated speeds. Which boards would be good to look at? Gigabyte and AsRock would be my preferred choices, but is it too early to pick one, or should i wait to see how bios updates and the windows 10 updates to progress? at the moment im running an i5 2500k with a gtx1070, but am looking at ryzen to last me at least 4 years, but dont want to pay over 200 just for a motherboard. Thats what put me off x99.

There are some teething issues because is something brand new. But I believe those who have the B350 Tomahawk are pretty impressed with the capabilities of the mobo, and that it can overclock nicely.

Also you will find all Ryzen motherboards are advertised X+4. The 4 VRMs are needed for powering the SOC inside the CPU.

The first number is usually the power phases for the CPU. The second usually those for memory (if they have a dedicated power circuit), but can sometimes include other on board components as well. It just means they are separate from the CPU.
 
What went wrong with it?

The R9 290X launched with a rushed out cooler,and one or two issues,but if AMD had held back the launch a bit longer to refine things and launch with aftermarkt coolers,the impression of the R9 290 series would have been better - I knew so many who ended up thinking it was hot and throttling and they were mostly not enthusiasts on forums,but gamers and I needed to explain to them it that the third party models were better.

Nvidia actually sent cards to reviewers to highlight "the issues" with the card especially on quieter settings - reviewers actually mention Nvidia sending them cards.

Look at the R9 390 series - virtually the same cards,yet have a far better impression.

It's great that ryzen wasn't delayed, people who don't mind testing, tweaking etc have some fun and those who like everything more stable can wait (like they would've anyway if it was delayed).

There is nothing wrong for consumers that it was released when it was. Everyone is aware it's new, it requires updates, support from everyone around so buyers know what they are getting. You'd prefer it was released 1-2 months later? just buy it in 1-2 months when it's more stable, what's the problem? That you can see all the testing, all the bugs that wouldn't have been found otherwise? or are you worried about financial state of AMD?

Because its the same with some of their other launches - enthusiasts will tweak,etc and ATM I have less techy friends of mine who think Intel is still better for gaming and Ryzen has bugs,going by the launch reviews. Then you need to keep explaining to them,give it some time,a month or two so don't judge it fully yet.

Its like with my mate who wants an R7 1700 for non-gaming use,after I told him about Ryzen before - he sees all these "issues" with the motherboards and just wants a stable build and this is why I am trawling through forums to make a list. It worries me,because even when some reviewers like JayzTwoCents basically said Ryzen CPUs are decent,but he cannot recommend it yet and then points to the motherboards,its not great PR for AMD especially considering people like him have like a million subscribers.

Its like on the graphics side - most of the time they compete really well with Nvidia even several times at the high end and then find some way to give room for their competitors,and all of us know in a few months that many of the AMD cards mature,and show decent improvement. Then you get people still buying Nvidia,so in the end its just this own goal mentality which I get annoyed about with AMD.

I mean the motherboards are not even available in quantity for a number of models,and BIOSes are not entirely there yet - so even the blasted launch reviews are probably not even going to be that accurate I think even in a month.

If they launched in a few weeks time,they could have had at least some of the Windows updates in place,more time for motherboards with more refined BIOSes,etc.

I mean if you listen to what AMD said within a day of the launch,they apparently were aware of the fact some of these fixes were incoming.

Remember I was the one who found that comment about the first Windows updates being released with the R5 1600X launch.

Plus that is another thing - launching the R5 and R7 together with the Windows updates would have been a 1,2 punch to Intel.

TBH I don't know why AMD don't design their own reference boards for launch or they should at least work with Asus/Gigabyte etc more before launch to iron out the bugs, in the end it's their reputation on the line and all of these issues are going to stick to the Ryzen brand.
 
Just booted my 1700 + Gigabyte Gaming 3 up. I always hate that nervy first time you press the power button.

Will post some comparisons between my old 2500K at 4.2ghz and this.
 
Just slapped the 1800X @ 4.0GHz @ 1.425v with Level 3 LLC. Run Realbench a few times fine, running Prime95 now. I'll start lowering the voltage.

Best way to put these chips through testing?

Hit 74c in CPUI HWMonitor and 73c in the ASUS software, though not at the same time.. The temperatures seem to be a bit odd, not sure what software to use or if it detects it properly.
 
What clocks are people settling on?

3.6ghz is stable for me with 1.150v bios (1.096v min under load).

3.7ghz requires 1.2125v bios (1.176v min under load).

That seems pretty efficient. I don't have the cooling yet to go for max clocks. But it seems silly to go for 4ghz at 1.4v+ for 24x7 setting?

I've settled at 3.6 as well. I have the cooling for 4ghz but I personally feel it's a lot of extra voltage for not a lot of gain

It's just a shame that you lose single/dual core boost which is probably still fine under the lower voltages.

That is exactly what you get with the 1700X/1800X I guess.

If you have the time, would you be able to do a thirty minute run of realbench stress test for 16 (assuming have thirty) and let me know how it goes.

I just need to figure out if I need to send all this Ryzen rubbish back, or stop running that test.

3.7ghz @ 1.2125 is the max you got? Try to push it, because newer bios versions on most boards allow better overclocks at lower power.
Last week, many needed 1.3+ for 3.7Ghz.
So you only have to try.
AMDMatt pushed his 1700 @ 4Ghz with 1.35v on the Crosshair Hero with the latest BIOS.

Still on stock cooler. Waiting for Gaming 5 motherboard to arrive and then I'll get a UH14S.
 
The stock cooler is a 95W cooler, nothing to snort at.
Given that 4Ghz @1.35 is around ~100W, and given how low your voltage if try to see how far you can push it at 1.3v.

True I'll try it in a bit.

Anyone else confirm what their stock clocks are on the Tomahawk?

I'm getting 3.2ghz (cpu-z and and hwmon) for the r7 1700 which doesn't make sense. 3.75ghz single core boost.

Also noticed it uses upto 1.336v under single core boost.
