confused about my 3800x

[aleda]

So i just got a 3800x installed first ryzen 

 

here is a screenshot havent been able to get super great cinebench r15/20 results but the undervolt is stupid low if i bump it up to say 1.35v it hits 80c no problem I have a h115i platinum for a cooler.

because smaller node (7nm) means all the heat (tho less of it) is cramped into a smaller volume, making the CPU harder to cool

It hits 80C in aida64 or in cinebench?

I don't understand what you mean by "undervolt". That is the stock voltage for the CPU (the one in your picture).

If you increase the voltage beyond stock to achieve better overclocking, the temperature will naturally increase.

before i adjusted the voltage my stock was 1.424

That's insane for these chips. Bear in mind that the default behavior is to adjust voltage and clocks according to boost states, so you may see a high voltage, but when only one core is boosting. However, you should see more reasonable voltages when all cores are loaded (and clocks adjust downwards wrt the one-core boost clock).

 

Check the profiles that come with Ryzen Master for your CPU, there you will see what a "fixed" stock voltage would be for your CPU.

For the TR 1920X, it certainly is 1.225v or 1.215 (but without setting it manually or through the profiles, it also swings around from less than 1v to 1.4x).

I mean over 5 in cinebench is pretty good. Well on my r7 3700x oc to 4.5ghz i can get similar score to yours. And with 360mm radiator i hit 85c. BTW you should use ryzen master to create new profile and manually put your coreclokc to advertised boot or 0.1ghz more. And then make sure that your voltage is not more than 1.4.

ignore reported voltage in stock condition because it has NO relations to all-core overclocks voltage, with all-core overclocks stick to 1.325 volts if you want a safe rating you can set and forget.  1.325v will also likely run cooler then stock, with about 6-8% performance improvement in multi-threaded applications (about same as stock in single core) but that is my experience and ive seen mixed results so far as thermals and power consumption for running 1.325v all-core OC, may be mobo dependant.

I get less or same power consumption and notable drop in thermals with overclock and 1.325v, meanwhile on a GODLIKE motherboard, with their own BIOS config GamersNexus somehow gets basically same improvements (6-8%) but creates a nuclear inferno inside their CPU and draws 1.5x power rather then reduced temps and same or less power consumption.  Bless steve but sometimes i worry about him.

for stock configurations during turbo, no it isn't.  For sustained load (5+ minutes) yes it could be, but we're talking to a guy who just got the chip and i doubt if he ran with stock configuration for long period of time it would maintain that, nearly all Ryzen 3000 hit these voltages briefly during onset of a load.  Even if it did maintain said voltage its likely not same as seeing or running this with static overclock given how Ryzen 3000 works.
