AMD - Zen chitchat

That seems a little high, maybe 3-5 degrees more than I would expect. Nothing to be too concerned about (After all it works like an electric heater in the winter right?) I wonder what thermal compound you used? You could perhaps have another stab at that with something different. However, having typed that, 1.375v on a 7nm chip seems a fair chunk of electrons to be throwing at it. It's just possible you ended up with a Ryzen that's on the hot side of normal.

Take the side panel off and see what the max gaming temp is and report back if you don't mind. I have a 1700 and even at 4ghz and 1.38v it wouldn't probably hit 77c gaming with an NH-D15. The D15 should be max 1-2 degrees cooler than your already excellent NH-U12A unit (I looked it up). I would expect, with both my CPU fans fitted, 72-4 degrees. I have neither gamed nor overclocked in some months though so I can't be sure, and we haven't accounted for ambient.

The 580 should produce less heat than my Vega too. I think there may be room for improvement in your 77 degrees.

My GPU actually runs cooler than my CPU when gaming! My RX 580 usually sits at around 70C when gaming.

I'm using the Noctua NT-H1 thermal paste that came with the cooler. I usually use Arctic MX-4 but I doubt there's much difference between the two. My case also has 3 x 120mm Cougar intake fans and another 120mm as an exhaust (I did have two exhaust fans, but one failed recently).

Have a look in your BIOS and make sure your voltages are set to 'normal' not 'auto'. Auto settings tend to whack up the voltages.

I'll double check, but I don't recall seeing a normal option in the voltage menus. I left it all on auto as I'm pretty sure the other option was manual. I'm now waiting for Asrock to hurry up and release the latest BIOS with AGESA 1.0.0.4 update (Asrock have always been a little slow).

The performance of my Ryzen 5 3600 is great for the money, but I'm still a bit unsure about the voltage and temps... They always seem a bit too high, especially seeing as it's a 65W chip and at the lower end of the Ryzen 3000 series.

Voltages reach 1.450V when the cores hit 4.2GHz, and the voltages usually hover around 1.375V under load when all cores are being used (usually at 4.05GHz with all cores in use). I'm seeing temps of around 77C when gaming and that's also with a Noctua NH-U12A cooler which is one of the best, if not the best air cooler out there! Case cooling is also good. The motherboard I'm using is the Asrock X470 Taichi with the latest BIOS available (3.60).

VRM temps, chipset temps, drive temps, GPU temps and RAM temps are all fine. Even the side panel of the case gets pretty warm behind the CPU area after a bit of gaming (currently playing The Outer Worlds).

There was a fair amount of confusion about this around launch. Basically, if your BIOS settings are sane, it's likely normal and/or some software isn't taking the readings properly. More information here: https://www.reddit.com/r/Amd/comment...3rd_gen_ryzen/

77C does seem a tad high for load temperatures though, assuming it's a correct reading. Did you have a previous CPU to compare? If the heatsink is pulling in warm GPU air in a poorly-ventilated case for example, it would be hard to get decent temps regardless. Also make sure PBO (precision boost overdrive) is disabled in BIOS as it's effectively an overclock.

I don't know the ASRock specifics, it could be manual (and then just leave it at the default value).

No "effective" about it, that is an overclock setting and IIRC invalidates the CPU warranty by enabling it.

My 3D printer has a Noctua fan on the hotend, they are getting an infamous reputation for being whisper quiet but not actually doing the job of cooling the heatbreak. It could be you simply need more rpm on that fan in the profile.

The Noctua fans spin up to near their limit when the CPU starts getting toasty (I think the max is 2000rpm for these fans). I didn't know about PBO invalidating the warranty. Asrock have the PBO setting as "auto" by default so I'm not 100% sure if it's being used or not.

It shouldn't be on. Precision Boost is a performance setting that should be on. Precision Boost Overdrive is an overclock setting that wacks the heat right up for minimal performance gain. The two seem to get commonly confused, which given the naming isn't surprising really

Is Zen3 going to be compatible with AM4 Mboards?

It's likely to be on AM4 socket (for the consumer chips), but whether *all* previous AM4 mobos are supported we don't know yet.

Two big things here:
1) AMD is still making 2XXX ryzen chips, and until recently was still making 1XXX parts
2) They're now selling rebranded 2600s as 1600s, for 1600 money. That's a tough value offer for any modern chip to beat

Yeah I just watched that.

I wonder if this is one of the AMD pro parts that they promised 5 year availability for, in which case re-marking a 2600 as 1600 is a tad naughty.

But still, that's cracking value if you can find one. I just had a look and could only find 1600 AE parts in the UK.

Amazon have been selling the AF in the uk for a while, I'd post a link but I don't think I'm allowed cos affiliate links and all. Just look at the product details section (been on sale since september appatently). Does this mean the zen 14nm line is dead? does this also mean that mobile chips are going to share the same series name as well (...soon?)?

Interesting, I could only find:

http://amazon.co.uk/AMD-Ryzen-1600-D...dp/B06XNRQHG4/

which claims to be YD1600BBAEBOX (not YD1600BBAFBOX)

But yes, it sounds like 14nm parts are no longer made, but this is new 12nm silicon. Maybe AMD had some 12nm wafer starts to use up, maybe they had a warehouse full of 2600 parts and decided to remark them to justify a lower price. Who knows.


Edit: Found one...

http://amazon.co.uk/AMD-CPU-RYZEN-16...dp/B07XTQZJ28/

but that's more expensive than a 2600X let alone a 2600 so I'm not so tempted

https://www.amazon.co.uk/AMD-CPU-RYZ.../dp/B07XTQZJ28 Here you go. Abet without a lower price than 2600's

lol, both dug it out at the same time.

Noticed it wasn't in the top selling list though, which is amazingly AMD dominated these days.

Good leak.
The top 65W 8C/16T APU should be quiet interesting, but I also guess it will demand a very high price as it's the first time AMD have had such a high end APU.
Will be interesting to see how the monolith compares to 3800X when matched to fast DDR4 as the laptop APUs really don't have much tweakabilty.
However, that's the second one of his videos I've watch and I really don't get that Igor guy, or his website.
