Ryzen max safe voltage

[jjohnthedon1]

So yet another post from me 

sorry new platform lost of questions

 

in stable at 4ghz at 1.417 under full load (not under load idles at 1.439(wtf ?))

 

iv read loads of thing at 1.35 is the limit 

1.45 is the limit 

 

Xfr is pushing some people to 1.51v

 

so am I ok running 1.417/1.439 constant voltage?  Temps top out at 59 degrees under full load

@DocSwag might know.

Lol why me  

 

I recall that the highest you should go is around 1.45v, kinda similar to skylake which is interesting .

 

Though I think closer to 1.4 is better.

 

Most likely though you'll hit a wall around 4 ghz anyways that won't require a whole 1.45v, but who knows.

You seem to bounce around every Ryzen thread. I assumed you would know like @deXxterlab97 knows his 50 Shades of Blue.

1.417 is stable 1.39 is not 

but I'm getting v droop so I have to set it to 1.44 to get 1.417 under load 

are my tempsgood under load ?

1.450 prolly can be a controlled max with air/water cooling. most do recede to 1.375-1.425v, just watch the temperatures if you have a reliable monitoring app. 95° (75° + 20° offset = TctlMAX) on the core seems to the redline, 90° for intense workloads, or 85° for a 24/7 driver. So max recommended TCTL for 1600 is 95, 75° real.

Untill the good old blue smoke appears, then back it off and hope for the best.

1600 doesn't have the 20 degree off set only the x chips and my temps top at 60

Just fixed the vdroop issue so I can run 1.41v idle and under full load now

it flickers up to 1.44 for a split second every now and again but mostly 1.41v now

Not EVERY one...

 

Only the ones that are around while I'm online 

 

To be fair, I'm on pretty much every new builds topic that I see in the recent topics, while I'm online

Is it possible to turn LLC down?

Iv set it to level 3 in the bios now and it stays at 1.417 idle and under load now

with flickers to 1.439 just for s second

That seems to be fine

Current "conventional" wisdom seems to be: do not exceed 1.4v for daily 24/7 usage, or you may see "some loss of component longevity". I couldn't get 4.0 stable @ 1.425 on my 1600, and that's where I drew the line. I'm back around 3.9 @ 1.4v now, and I'm going to see how much I can drop it (though I forgot to test 3.925, 3.95 and 3.975, which I may do if I get bored).

Iv read a lot that 1.45 is the line with good cooling 

I was stable at 1.45 4ghz in everything apart from one program that crashed me in rendering even tho I passed r15 20 times,

 

however at 3.9 I dropped the voltage to 1.33 ate its stable in aida64 8 hours 

and stable in rendering and gaming and temp are 50 max in gaming and rendering now so it was a lot of heat and voltage for pretty much no gain

1.439V shouldn't bother you but what is your Ryzen 7?! I want to know how and with what are you overclocking!

What if I just get my voltage to 1.375V and then Click it to at least 3.8 GHz on your CPU?

When overclocking I monitor performance and power draw at each setting, and stop when diminishing returns kicks in.

Increasing my R7 1700 showed gradual performance increasing from 3.2 to 3.6 GHz, then required increased voltage to get to 3.7 and 3.8, although 3.8 GHz was only showing 1% (margin of error) performance increase over 3.6GHz. I just stuck with 3.8 GHz 1.3V as there was no benefit to me going higher. Different workloads use the processor differently, so assessing the CPU which your workload to make an informed decision is recommended.

 

I would not imagine you would see huge performance differences at 4.0GHz over 3.9Ghz, and if it is more stable, it makes sense to stick with it.

Amazing, and how do you manage to get crosshair? Is it coming with an AC connection?

Well yeh because it's a rj45 clip cat 6 and 7 are rated for longer distance but are the same as cat 5c
