Any here do undervolt for GPU and CPU?

[Yongkit]

65c is awesome. Ltr I try uv. What's your core clock?

I limit it at 1935MHz @ 937mV +500 Memory clock.

I enlarged my graph above for better reference.

I just watched this video and looks like CPU undervolt for Ryzen 5600x is not really that worth it.

agreed as 5600x already low power high performance cpu, undervolted does not do justice to this performance chip.

since you have 3600 memory profile, you can try OC it 4 steps above and check the benchmarks again see how it perform, as this is also my memory OC profile with 4 steps above.

then try to play a game, if unstable you can drop 1 step in the memory oc and try again.

Hi guys, I have been watching youtube for undervolting as I changed to ITX case.

For GPU, I'm currently using on RTX 3080 Ventus OC.
0.9mV @ 1935Mhz using MSI afterburner.
Only tested using Unigine Heavan 4.0
Got a score of 6988
Min FPS: 55.3
Max FPS: 550.2
Temp: Max 67 deg (HWMonitor)

Curious what settings u guys have and what software u guys test with?

Do you also undervolt your CPU too?

I uv both my 3700X and RTX3080.

For 3700X, I do not remember the settings but you are using Zen 3 so different.

For RTX 3080, I have a few profiles - all stress tested with Port Royal with 20runs and games such as quake rtx and SOTR.

825mV/1875Mhz

850mV/1920Mhz

893mv/1950Mhz

All with +500 Mem

The strange thing is that there is ONLY a diff of max 3 to 4 FPS loss.

i undervolt my cpu to 1.184 volts.

I enlarged my graph above for better reference.

I UV again. 1948mhz @ 925mv, temps went down to 65c. Looks like I was airflow choked previously. I raised my casing a couple inches more and it got better. 3080 aorus master on nr200p is a bit stupid hahaha

Glad you found the cause of the issue enjoy your new setting and see if it is stable for your fav games

my sensei Proximus just shared his setting too maybe you can try too

Speaking of undervolting gpu, I saw several youtube videos. All like decrease the overall core clock first like 280-300 mhz, then increase back from around ~825 mv. What’s the purpose of decreasing overall clock first?

is to pull down the graph, so the highest number there is lower than your target clock speed.
so when u drag up the point for your voltage/clock, eg 800mv, 1800mhz, it becomes the highest point and every point above that voltage will automatically be set to 1800mhz when u press "apply"
stupid people like me drag each point 1 by 1 before they realise.

senpai.... thank you for kind words.

I just ran mine again using 825mV/1875MHz + 500 Mem, I am only 1 FPS less than you but at at much lower voltage and power. I max out at 60C and total GPU power max at 270W.

The beauty of uv and yet similar performance..

Sensei is always Sensei

I have try few time my GPU is unable to match your setting to go lower than 925mV, anything below 900mV it will crashed before the test/bencemarks completed

currently I am happy with my UV @ 937mV 1935MHz + 500 Mem, since the temp have been lower than 70c during the cyberpunk game @ average 75~85 fps using CinematixEXR_RTX shortcut game play

Undervolt cpu with the saem speed also consider overclock. It's
like feeding you smaller amount of food with same workload, it's a torture of cpu. If wan to save electricity or boost electricity, You can also dowm/upgrade fuse, and there are also high quality fuse for hifi which you can use if you can afford, goggle for hifi fuse.

I beg to differ. Imagine that your CPU only needs 1.29V to be at 4.5GHz but the mobo is giving it at 1.40V.... the CPU will be taking all voltage at the cost of heat......

It is not about saving electricity but efficiencyso that extra power is not turned into heat loss.

You are too modest bro.... The card I have OOTB is power-limited at 320W and it runs likme a hot pan with the default fan curve. The only way out for me is uv.

For your case, it is diff - STRIX is not power limited and I believed that the fans are properly tuned OOTB. You might even consider not to uv to get full potential of the card.

I'm currently running 0.85mV @ 1900Mhz. Does increasing the memory speed make a big difference? But I wanna get lower temp.

actually we dun know if feed the same amount of food to every person (every CPU) is the same. Some dun need to eat so much food to do the same workload. Those extra food u feed, will come out as **** (heat). So less food in = less **** out mah...

Based on my experience, increase mem clk will result in 1 to 3 FPS but in benchmarks such as TSP, a couple of hundred points. So note that depends on the card you have, you might get into instability and need to bump up the voltage. So it is up to individual on whether is it worth to up the volt for 1 to 3 FPS and of cos a slight increase of temp. But the latter can be compensated by fune tuning the fan curve.

The key is not to over do it, for my case, stay below 900 - I will not lose FPS.

I just done a testing for RDR2 @ Highest Setting "Favour Quality" @ 1440p 165Hz

Setting :

Normal GPU Power @ 2010MHz 1243mv 72c

GPU undervolted fixed @ 1935MHz 937mV 68c

not much different in fps but temperature drop 4c, this game is very demanding on GPU power, and i notice the sweet spot for this game constantly GPU @ 1935MHz even without uv.

a perfect undervolt is feeding as much as he needs. stock behaviour is to feed more than needed. if u undervolt too much he cmi will bsod but that doesnt hurt the cpu, cpu is damaged by over voltage, not errors.

 

[tsteo77]

Thanks guys, that i understand on cpu over/under voltage. To Lower it's heat. luckily I don't need to do this because my cpu idle or gaming sit at 48 degree c.

BTW, does anyone try hifi fuse ? Just google hifi fuse. feedbacks ?
