Wondering what people's all core overclock temps are, mine averaged 75c in gaming while being at 4425mhz. Kinda think that sucks, granted I only have a XE 240 cooling the CPU, but expected more. Maybe the Aqua is just mediocre and see if some sucker on the bay will want it, or perhaps i'm just expecting too much.
 
i have a 3900x at 4.4ghz under a 360mm ek custom solution and my load temps are around 75 degrees, tbh i can push 4.45ghz but temps do go past 80 so for so little clock gain its not worth it, most 3900x under all core clocks top out at around 4.3-4.4ghz so what you and i are running is pretty much what is to be expected from that silicone.

Ok, fair enough. I'm at 1.31, an extra 25mhz needs 1.4+, very strange.

i run just over 1.31-1.325v but going to said 4450mhz all core needs upwards of 1.4v which makes temps go nuts, running my cpu at default i can see 6-8 cores go upto 4575mhz and the rest settle back at 4300mhz, just the way the silicone is made i guess, still all cores and threads at 4.4ghz is really going some :)
 
yeah you could add anotehr rad on that and you'd find that the CPU temp won't go down that much and voltage is the killer. It's like me on my old stuff here... so go from 4.4ghz (1.260v) to 4.6ghz requires 1.365v and that adds around 9C to the max temps... all for 200mhz... but those temps seem fine to me mate... wouldn't worry about it those chips are tough to control, think if you had intel 12 core, you'd be seeing a lot higher than that lol. AMD do imho have a problem with overvolting though especially on auto, them things love to throw 1.4v and beware as there are now reports coming through of degradation of the chips running constant 1.4v or above so... just something to keep in mind.
 
I run a 3900x at stock auto volts in the bios. Custom loop with sufficient cooling. Asus X470 Pro with the latest bios update. Ryzen balanced power plan.

Bios seems to set the voltage to 1.4v even though its on auto.

Temps seem fine with it idle at 30, 35c. Idle voltage does drop into the 0.1, 1.1,1.2 ranges.

Gaming temps (Modern Warfare Multi and Warzone) are around 60c. All the cores seem to max out at about 4.2 GHz to 4.3ghz and the voltage reads 1.38v to 1.39v odd spike to 1.4v. I sometimes see 5 or 6 cores boost to 4.5, 4.6ghz but voltage still at around 1.4v

After reading about chip degradation, question is, is this still safe?

My voltage is rather low, not particularly concerned about degradation. Although, rather weird how AMD allows auto that high.

safe 3rd gen ryzen voltages are around 1.3-1.35v ideally, the auto voltage is far too much for any of the 3rd gen line up and for the extra 100 or so mhz more you get the extra voltage and heat really isnt worth it in the long run, going back to voltages if you try and run the lowest you can get under auto or overclocked conditions, there was a statment/tweet from amd that was circiling around the web that the lowest you go is 1.28v and even then that may be too low and cause degredation or damage of the chip's.

if you want to play it safe don't go below 1.3v and at the upper limit around 1.325v but every cpu is diffrent so you may need more but try not to go below 1.3v and stay as far away from 1.4v as you can, most cpu's in the 3rd gen line up 3600 - 3900x should hit around 4.3ghz all core at around 1.325v, the newer xt and 3100 - 3300x can push more volts and speed as the core layout and quality is better, as with everything overclocking wise have a play and see what your silicone can do :)

Thanks for the reply. Yeah ive just seen a video posted by Jayztwocents saying leaving it at the stock, auto, default voltage is fine and it wont damage the CPU.

Great thanks. I had a play around at 1.25v just to see where my minimum is at and low and behold I get and additional 200 points on cinebench all core sitting at 4.1ghz. 7100 at stock volts and around 7300 at 1.25v. Thats the only change ive made in the bios everything else is auto.

I'll have a play at 1.3v now and see where im at.

What are everyone's reported voltage during gaming then?

Cinebench undervolts the core voltage even at 1.25v for me too 1.187v all cores at 4.1ghz and passes it fine multiple times.

under heavy load and during gaming my core voltage never drops below 1.3v as i've set a high load line calibration setting of 5 on my asus mobo, at stock speed i can hit around 7100 points on r20, but oh my how things improve under a all core 4.4ghz @1.325v, my r20 scores push nearly 7800 overall.

regarding voltages if you have the cores set to auto then i think a low voltage should be ok, just dont smash a high all core overclock with little to no voltage as thats were the troubles are likley to start, same too for too many volts.

your cinebench score shows a all core clock around 4.1ghz sustained which wont require much voltage to hit, the problem is when your cores ramp up to close to advertised 4.6ghz thats when the voltages will spike up to 1.5v which is needed to sustain that clock, but thanks to temp's increasing the cpu downclocks and reduces voltages and heat.

if you increase your voltages to 1.3 then your all core overclock should be around 4.3ghz all core perhaps 4.4ghz if your lucky, you have around 10 degrees to play with before it starts to get uncomfortable for the cpu (70-75 degrees max)

have a play and see what your chip can do (unleash the beast) XD
 
Thanks again @wookiee87

I tried the voltage at 1.3v and noticed much improved temps and some consistent all core clocks stabilising at 4.1 - 4.2Ghz R20 scores around 7200. Tested @ 1.325 volts I wasn't see much difference.

I tested 1.3v out on MW and it was stable and performance was fine I was seeing 4.2Ghz great temps in the 50s and no stability issues.

Everyone seems to saying to leave the thing on Auto and let it do its thing. This morning I set my OC on ram and decided just to test the auto voltage with a 0.1 offset.

My Asus X470 board applies a 1.48v core as auto but in Windows and in R20 full load it does under volt as required using the balanced power plan. Ive uninstalled Ryzen Master for this test.

This is my MW load screen which pins the GPU at 100% and uses the CPU cores as required, there isn't 100% load on all cores.

SVI2 Vcore average is 1.38v - CPU temp 63c - Water temp 39c (warm day today) 70ish watts CPU package power.

What are we saying then is this safe enough to use gaming roughly 3-4hrs every other day?

the voltage for that clock is a tad bit high, for around 4.2-4.3ghz all core you should be aiming for around 1.3v ish, amd's software always compinsates and pushes far too much voltage.
your screenshot above shows around half your chip running below spec (3.4ghz) and although good enough for gaming if that happens in benchmarking programs or multi media applications you'll notice it feels slow.

running out of the box the performance is very good anyway, its just the auto voltage is bad, i've had 4.4ghz applied since i got my chip and had a steady 1.325v applied too and have had no problems what so ever, if your not going to aplly a all core overclock then back down the voltages closer to 1.3v and leave the multiplier on auto, that way the cpu will ramp up close to 4.6ghz as and when and should maintain 4.2-4.3ghz on most cores as the load increases.

the 3900x is good temp wise up to around 76 degrees, after that it gets a bit iffy really (my chip does anyay)

also why is you chipset running at 6 million degrees???? XD
 
Again thanks so much for the reply @wookiee87

Ah yeah nice eagle eye there mind you that figure does stick out a mile....it was bugged out as soon as I updated the AGESA 1.0.0.3 to support Ryzen 3000 (ASUS X470 Pro) need to fire off a few emails to ASUS about that as they were working completely fine before the update. Currently the Chipset and board VRM temps are broke. Kind of handy for me as the VRM are water cooled too via Monoblock

I think I might just do that then and lower the voltage to around 1.3v as you say and leave the core clock on auto.

Temps and speed from my chip seems to be much better. I'll have a play with this and see how I go.

Sorry @random_matt for jumping in on your post its got me tinkering.

I don't normally mess around with all these settings but I really want this chip to last me a long time maybe 6 years plus and not start to give up as its only a year or so old. :)
