Undervolt your Ryzen 7 3700X for more FPS and Lower Temperature!

Those Ryzen 3000 CPUs can be quite a bit power hungry if you let them behave like they want to, which is why today we're setting this R7 3700X to be more performing in multithread AND more power efficient, with lower temps and stopping it from overheating. The only downside is losing a bit of single core performance, but it's negligible in the real world!

This also works for the following models of AMD Ryzen 7: 3800X 3800XT

-0.05 worked like a charm. -0.075 crashed my PC. My CPU freq went up by 100 Mhz while maintaining the same temperatures. Thank you very much, really appreciate this video!

I don't speak English, I'm using a translator. Thanks to your video, I managed to reduce the temperature by approximately 15 degrees. Thank you.

Hello, I am writing this through a translator. Thank you very much for clearly explaining, the settings applied well to the Ryzen 7 3800X, the temperatures dropped by about 11 degrees in AIDA, they were 78 to 67-69, and the overall performance and stability became a little better. Thank you very much again for your video, it helped a lot.

[ianferreiraian]

It worked great for me. More than 10 degrees Celsius less.Thank you so much!

[farmingnodak]

Dude you're awesome... I've been re-tinkering with some cpus and gpus and been coming across your videos often 😂 A lot of good starting points to work with and able to tweak from there.

Thanks heaps for the tips, you are straight up the best

[Babsi]

clear, simple and straight to the point <3

My man, this is great!!! It worked like a charm!!! Grazie!!!!

[ariyanab]

Hello, my temperature did not change and I did everything correctly and saved

[brbbst]

On Gigabyte x570 Aorus Elite those settings are alot more complex.

[chrisb]

Can you do one for the Ryzen 7 2700X please!

[pitzuki]

I wached this video a couple of times and i was not sure to do it. I just did, i will updste to see how ir performs.

[iamec]

Hey, I do not have any settings lik the vddcr cpu voltage setting in my bios. Why?

[david_schuster]

Great videos man. I'm new with undervolting so your channel has been very helpful. I have this same CPU and with the settings you're sharing I get some random restarts... They're not often but still... What can I do to make the system a bit more stable? Thanks!

[tanjem]

I now understand why motherboard manufacturer set the vcore voltage to around 1.4 v..it is for the boosting of the cpu ..to its value set in the box.. for some cpu, if the voltage is set too low, it will become unstable as the cpu boost itself .. and if the voltage is set too low.. then more current is needed to sustain the boost . .. and hence more current will also heat up your cpu .. so .. in my conclusion, for ryzen 3700x .. it is better to set the voltage to 1.3 to 1.35 range for long term operations .. you notice that it still boost to 1.4v when the cpu needs to draws more power ..This is normal actually and nothing to alarm.. as long as it is not run for long hours.

Can i apply this settings with stock cooler (Wraith prism??

[gamertechlive]

I followed this guide a year ago however not all ryzen 3700x will be stable at -0.075V offset.
Mine is stable in prime95 & OCCT Small FFT + AIDA64 24 hours test each.
However its unstable in idle it causes code 19 error in the event viewer PC restart when idle yep only in idle state and fully stable underload = not stable.
I find out that at stock the highest offset i can set is -0.066V which fixed the code 19 error/random restart in the windows event viewer.
Now i applied PBO manual x2 scaler, +200hz auto OC & manual value 300-230-230 for power limit and 120 thermal limit.
What happen is since the power limit is now gone and the 3700x can use the max power it is allowed the offset -0.066V is no longer stable and need to tune it down to -0.054V to become fully stable.
Now i tweak the system again to gain a lil bit more performance by disabling C-state + AMD cool & quiet (cpu power saving modes) & pref core (ryzen 3000 better to turn off while its better to turn on this on ryzen 5000).
I also disabled SMT to gain more perf on games that don't use HT (specially in Online MMORPG games are not optimized for HT).
Disabling SMT reduce temp which mean I can increase the offset value since its no longer using the additional thread.
I increase offset value to -0.090V (best sweet spot for me -0.0096V is stable but find out that single core & multi core performance drop).
Set Bclock to 100Mhz.
CPU's IF is also OCed due to RAM manual OC of 3733Mhz 98% manually tuned RAM past all RAM stability apps yep ALL for 24hrs -48hrs++ each test (to much work last year took me 6 months to stabilize GDM Off 1T w/ the tightest primary, secondary & tertiary timings).
Oh... i don't advice the Vcore offset, if this is ryzen 5000 yep you can do that for 3200Mhz XMP even on manually tuned RAM OC you can get away with 1.1V or even 1.05V for good binned ryzen 5000.
I'm currently at Soc Voltage 1.190 V. for my RAM OC if i reduce it this will produce error in 1 or 2 Ram stability app, well 1.2V is safe for ryzen 3000, If i remember correctly 1.25V for ryzen 5000 when pushing above 1:1 ratio 4000MT/s OC

I want this set up and play Red alert all day.

[mujahidhasan]

sorry for my broken English, I hope you are well my brother, I have a stock cooler And my room temperature is around 28 to 32. can I use your bios setting??
if I do will I lose performance in game??
or my PC will crash??
because I have a stock cooler that's why I'm worried.
