Asus EZ Tune question

jeffrey_dibartolomeo · Sep 9, 2018

Here is my build:
Asus Prime X470-pro
Ryzen 5 2600, stock cooler
Corsair Vengeance 3000MHz, CL 15
Sapphire Nitro+ RX580

I haven't OCd before, and I got my ram running at 16-17-17-35, while it's supposed to be at 15-17-17-35. After reading, I understand AMD chipsets have issues running at odd latencies, but whatever, the difference between 15 and 16 clock cycles is imperceptible to me.

So I went into the bios EZ tune feature, and the bios would auto OC my cpu 2%. Now I did this just to see what would happen, as the computer is plenty fast for me. Using EZ tune, it raised the cpu ratio from 34 to 35 and left everything else the same (voltages, etc.)

My questions are, will a 100MHz OC really do anything or be noticable, and will it theoretically shorten the lifespan of the processor?

My question is, would you do anything that might benefit from 2.9% boost? Games won't need it. Your GPU would bottleneck it unless you're playing on low res/high FPS setting.

Also, Precision Boost/XMP/whatever should boost up to 3.9GHz. Enable it if you need the extra performance.

will it theoretically shorten the lifespan of the processor?

It will "theoretically" shorten the 10+ lifespan of the CPU which you will outlive. If it gets fried, it was faulty to begin with.

Also, keeping it cooler than 80c with the voltage below 1.400v is considered safe for daily usage by most people.

zebarjadi, thanks for the reply! It's not that I would benefit from a certain boost level as I said in my OP that my computer is plenty fast for my needs, I'm just playing around with OCing using the built in tools and the stock cooler. If AMD markets this as 3.9GHz max boost from the factory, then I want achieve that...because I that's the product I bought, not because I'll necessarily use it. So, under the CMB -> NBIO common options in the bios, I only have a "mode0" setting that I can set to auto/enable/disable. This seems to be a confusing option as I, along with others online, can't seem to find out what this does.

Do you happen to know what mode0 is?

Never heard of it. If it's not included on the manual and no one knows what it does, it's probably not intended for consumers. Motherboards have lots of little known options if you dig deep enough. Mine has 10+ voltages and 30+ RAM timings and I only touched half of them.

PB guide on ASUS.

Also, Ryzen is very picky about BIOS. If it causes problems, you might wanna update it.

thanks for the link, but that one isn't for asus...it's for diy liquid cooling a gpu.

Oops, my bad. I got sidetracked by Jayz exaggerated comment on DIY watercooling. :heink:

Double checked this one. It's Asus.

jeffrey_dibartolomeo · Sep 9, 2018

That's the video I watched earlier. When I go to CMB -> nbio common options, I only have the "mode0" settings. I do not have any of the other settings, and I'm running the most recent bios. I agree with you that there are many settings that 99.99% of us will never touch, but it's a little weird that I only have that one setting in nbio options.

zebarjadi.raouf · Sep 9, 2018

Weird. Maybe Asus changed the location on recent updates. Look around the BIOS especially Advanced + Ai Tweaker.

If you don't find it, leave voltage on auto and manually enter 39. Or use Ryzen Master if you prefer software.

I won't be here for the next 12hours. Plenty of time test and look around. Learn BIOS while you're at it. Makes future builds/upgrades adjustmens much easier.

jeffrey_dibartolomeo · Sep 10, 2018

I've poked around in AI Tweaker, but haven't changed anything other than TPU from "keep current settings" to "TPU I." When I did that, it clocked the cpu at 3.85GHz. But if it's normally clocked at 3.4GHz with a boost clock of 3.9GHz, would manually increasing the ratio to 39 really "overclock" it, since that's the factory boost clock anyway? I was under the impression that AMD's precision boost 2 was dynamic and would constantly update for the current conditions, not something that was determined at boot time. What I've yet to conclude is, do I have to enable precision boost, or is it enabled from the factory, and sensors on the cpu adjust the amount of boost? Or maybe I just have to enable it on certain boards, like the on Asus prime x470 that I have?

One thing I found interesting was went I went to change the TPU settings, the description for TPU I said "for air coolers" and TPU II said "for liquid coolers." I changed it to TPU I since I'm running the stock cooler. And this leads me to believe I've found my answer, which is, if I enable TPU II, it would probably clock to cpu at 3.9GHz. So on my board are the TPU settings a way to enable precision boost while telling the board/cpu what kind of cooling you have?

I know, sorry for the rambling questions. It's just frustrating that AMD hasn't made a uniform setting across MB manufacturers. And this causes a lot of confusion, from what I've gathered.

The settings are uniform across all vendors. The vendors, however, like to do things their way as much as possible. So while the actual function of any given setting is identical, the names are quite often different. Uncore is the same thing as System Agent or VCCSA or even Northbridge voltage for example.

Your cpu has a set of Intel optimized default settings, this is stock and runs when there's no outside influences. This includes a basic 'turbo' function which changes a few settings and opens the multiplier past base speed. Asus goes one step further with TPU (TurboV Processer Unit) which in TPU 1 will bump a small OC by using just the multiplier and in TPU 2 which not only bumps the multiplier, but the BCLK too. Why it's labeled 'aircooler' and 'liquid cooler' I can only speculate based on multiple posts where ppl assume you need liquid cooling for good OC limits and Asus is exploiting that inaccuracy.

It really boils down to usage and attitude. The healthiest way to OC is manually, but includes stuff like totally shutting down any and all EPU/TPU usage and other power saving/bumping stuff like C-states, power phases etc. Then there's the lazy way (which often gets ppl in trouble) using the TPU and OC Genie, TurboV in windows etc. The addition of EPU is a gimmick. It's a way of getting past any Energy restrictions or requirements like what Europe has instituted. Nobody in their right mind would spend extra on a high grade cpu, just to cripple it with upto 80% energy savings and capping the cpu at 40% usage. EPU on a mobo designed for overclocking is, in a word, retarded.

zebarjadi.raouf · Sep 11, 2018

would manually increasing the ratio to 39 really "overclock" it, since that's the factory boost clock anyway?

Techncically yes. Anything above stock setting is overclocking. Most people are afraid/unaware of overclocking, so factory boost helps them.

AMD's precision boost 2 was dynamic and would constantly update for the current conditions, not something that was determined at boot time. What I've yet to conclude is, do I have to enable precision boost, or is it enabled from the factory, and sensors on the cpu adjust the amount of boost? Or maybe I just have to enable it on certain boards, like the on Asus prime x470 that I have?

I'm not sure about AMD but on Intel, it's on by default. Also, it's one time set and forget kind of thing. I usually go over BIOS and adjust everything neededevery time I build a PC for someone.

One thing I found interesting was went I went to change the TPU settings, the description for TPU I said "for air coolers" and TPU II said "for liquid coolers." I changed it to TPU I since I'm running the stock cooler. And this leads me to believe I've found my answer, which is, if I enable TPU II, it would probably clock to cpu at 3.9GHz. So on my board are the TPU settings a way to enable precision boost while telling the board/cpu what kind of cooling you have?

Overclock = more heat.
TPU1 = I have the stock cooler
TPU2 = I have a good cooler
Most people use stock coolers and the stock perform well at.... stock. and most other cheap air coolers are the same. But cheap working liquid coolers perform about decently when compared to air coolers.
Cheap/stock heatsink < cheap AIO liquid cooler = decent air < high-end AIO liquid = high-end air < custom liquid < LN2

I know, sorry for the rambling questions. It's just frustrating that AMD hasn't made a uniform setting across MB manufacturers. And this causes a lot of confusion, from what I've gathered.

The only thing I like about AMD is their cooler. Intel is too ashamed to give coolers to higher-end CPUs.:lol:

But, you're right. Every board has different names for AMD BIOS.

jeffrey_dibartolomeo · Sep 11, 2018

Eternal, thanks for the reply. Essentially, I'm trying to figure out how to "set it and forget it" like you said. I want to make sure it's on and working and not have to deal with it again.

I may play around with upgrading my cooler and going for a better OC, but for right now, the computer does exactly what I need it to.
