Yep and it was unstable at 3.9 even upto 1.45v
I have another than can do 3.9 at 1.4v

This is the silicon lottery, and I lost. The good news is the difference between 3.9 to 4.0 is minuscule and at that speed and voltage the heat output rises significantly it just isn't worth it in my opinion.

read a bit more of the thread now and yeah.... is starting to look like 3.8/9 might be a more realistic target.
Is the 1700X likely to go higher, easier? (I'd assume yes. Edit - seems not though, hmmm).

Just wondering what this will give me over the current [email protected], pretty much only for gaming.I can see it being a *bit* of a wash, maybe better minimum frames (which would be enough of a bonus tbh).
The bios on this board goes up to NVMe boot with a PCIe card so... I'm not really missing much I'd be after otherwise. Just a bit of an upgrade itch after sitting on this so long

Isn't 90c the limit? At 77 running avx for 8 hours if perfectly fine I'd say.
To the guys running loads of 40 degrees I'd say check your sensemi skew settings. My cpu also lies to me when this is on auto. It also thinks my cpu idles at 9 degrees in a 25 degree ambient.
When I disable this I'd idles around about 30 and hits highs of around 55-60.

Ryzen Master should report the correct temp without the need for any temp skews in the bios. Max recommended temp is 75c for all processors. Throttling won't occur until around 95c.

Corsair H110i.

When i bump voltage from 1.35v (3.9ghz) to 1.40v (4ghz) i gain about 20c on my load temps upto 65-70c on my custom watercooled loop. What are you cooling with?

I believe he is using a corsair 240 AIO
Which is what I have and I'm using 1.35v and i hit 55-60 on the silent profile. With fans on max its around 50-52.
1.45v and I'm into the 80's.
I think people have the sensemi set to the incorrectly if they are seen temps like 40 degrees under load.

I'm using default bios settings so no skew settings AFAIK.

My temps dropped after i reseated the aio and made sure it was nice and tight.

I also now feel heat coming from the radiator whereas before it felt like cold air, i guess its's doing a better job of dissipating heat now.

I guess i got Load line calibration at 3 so the voltage doesn't drop under load, im "happy" with 3.9ghz anyway. Would be nice to have 4.5-5ghz but hopefully Zen+ gets us there

Same, i'm sat at 3.9, would have been nice to get that nice 4.0, but in real world the difference is minimal at best. I'll wait for Zen+ and hope for 4.5+ being common.

Haha yeah, I think you're about right, you'll also potentially see another slight boost if you run other stuff at the same time as gaming (background tasks). Games like Fallout will also likely benefit from the DDR4 as it benefits a lot from higher speed memory although that is a rarity.

I'm on a [email protected] so in a very similar boat to you

As an aside though the Ryzen should use less power and run cooler than a cranked Sandy

Working my way out of the bootloop mess, 90% there I think. Only seen one in the last couple of days.

1700 @ 3.925 @ normal + 0.1875v LLC auto for 1.415v in the BIOS. This reports as 1.375v idle and 1.325v load under realbench.

Is that a particularly bad drop/droop? Seems it

The above with RAM at 3333 14-14-14-28 1.38v SOC at 1.175v is memtest stable for 2 hours and realbench for 1 hour.

I'm quite happy but a bit miffed at the voltage situation - do people when they say 1.45 volts is ok mean the BIOS setting or the actual load reported from the chip? My problem is id probably need 1.55v to see 1.4v under load!

AndreiD · 29 Jun 2017 at 16:31

You can set LLC to medium/3 if the vdroop is too much.
AMD recommends a maximum of 1.425V for 24/7 overclocking, so go with that. 1.45v might be in 'iffy' territory and lead to your chip degrading in the long term.

I run mine at 3.6Ghz at 1.15v seems that seems to be a sweet spot.

Ste · 29 Jun 2017 at 19:06

Ok have tried that. I can get 4ghz stable with

LLC3
BIOS voltage 1.5
Reported voltage after drop 1.45
Reported voltage under real bench 1.385

Does the 1.5v matter if it's not even getting that? I think I'd be ok with 1.45 idle as it's not doing anything and load temps are 65c max.

Thanks

AndreiD · 29 Jun 2017 at 19:11

I think you might have misunderstood me, and 1.5V is way too high! Lower it and don't go past 1.425V in the BIOS, it's the AMD recommended max, better safe than sorry.

Up to 1.55v is okay if you can keep temps nice and low with high end water cooling. Otherwise I'd stick to 1.45v or lower to avoid possible degradation of your chip.

That's my point - is it 1.5v just because the BIOS says so? The chip never reports receiving more than 1.45v and that's under no load, so temps are under 40. Under realbench it's at 1.4v and 65c on a 360mm AIO.

Sounds like you have Vdroop. Use HWINFO to monitor voltage applied. LLC can help reduce Vdroop.

AndreiD · 29 Jun 2017 at 19:43

According to AMD's Head of Global Technical Marketing, Robert Hallock, you're not supposed to go past 1.425v.

Quote: "[...] if you're going to overclock your CPU, try not to go higher than 1.425 volts, you are risking the long term lifetime of your processor by going higher than that"

Even if you have the most amazing custom water cooling, too high voltage will over time liquefy the transistors inside the chip, degrading it.

All of my measurements were from HWINFO. The probe that measures the voltage regulator (as fed from the VRMs to the CPU) - this is the one reporting 1.45 idle and 1.4 load. That is vdroop I think - voltage going down under load. I have curtailed this a bit with LLC 3/medium but still quite severe. Didn't want to go to 4/high really.

The phenomena of setting one thing in the BIOS and getting something else from the sensors is probably what is referred to as vdrop - also known as a crap motherboard / VRMs. Probably

In any event I'll probably drop to 3.9 but I'm not convinced the value set in the BIOS is of any relevance, rather what is measured coming out of the VRMs is what matters. Not that it's a huge issue either way when the CPU is such good value...

Awahwah · 29 Jun 2017 at 21:56

Reading through the OC attempts on here again makes me feel that my compromise is good.

3.825Ghz (love that you can do that) @ 1.325v via the Asus Zen tool, HWINFO reporting 1.286v load. Thoughts guys?

Edit: to add, that is 4hrs Adid64 tested and gaming (various) tested for I don't know how many hours - don't want to admit.

Edit2: Temps never go above 56' as reported via HW.

I have the same. Seems perfectly normal, vdroop is high on ryzen.

Seem's fine, I'm running 1.437v-1.512v. Full load is around 1.45v and light load idle goes up to around 1.48v-1.5v. Temperatures around 55-65c when gaming with my fans running silently.

I use LLC2.

Any advice on what to tweak to try and get memory stable.

I can boot to windows fine with DOCP 1, set to 3200. All seems good but benchmarking/testing gives errors.

What CPU frequency/bios settings are you using?

I would manually configure everything yourself, start at the beginning and use HCI to verify memory stability.
