Is under volting your CPU and GPU (by insane amounts) just going to be the new norm?

[R3L3NTL3SS]

People are under volting the Ryzen 7950X by crazy ass amounts and losing little to zero performance and reducing temps by literally 30+ fking degrees celcius.

What the fk are they cranking so much voltage into them for? Purely reliability and to guarantee it hits advertised clocks? It seems apparent that they don't need even remotely that much power to perform. It's definitely not a matter of getting a "golden chip" either because basically everyone who has done it is seeing success with it.

People are suspecting RTX4000 will be a similar situation too. Even RTX3000 cards have great success with some mild under volting.

Imaging taking the time to post in a thread about things you supposedly don't worry or care about.

Lmao what a fking loser.

[OptimusTrajan]

You will generally lose performance with undervolting, but it will use less power and create less heat. Just depends on what you care about.

[freeburn]

I put 6 fans on my cpu radiator and mounted it in the back drawing cold air thru my cpu never seen above 60 since I set it up like that

I ain't scared of no heat

Its actually a bit of fun. To reach the most optimal voltage-sucking setting while reaching the highest clock speeds and most ideal temps. Its a nice challenge always.

I had the 9900K running at 5.2Ghz (If I recall correctly) 100% all cores. The voltage it sucked and cooling it required was nuts. Not most ideal, 5GHz OC was where it was best.

very good times it was

Most gaming PC's are setup as total overkill these days, heat production has gotten out of hand.

With the 7950 people are getting temps into the 60's with no loss and into the 50's with as little as 5% loss.

For those not aware, that's from the 95C that AMD has them set to immediately jump to under full load. Reductions in temps that extreme from simple under volting while losing literally no-very little performance are absolutely unheard of and basically ground breaking lol.

Interesting. All I've heard is der bauer delidded one and got 20c cooler temps.

[Barteh]

How do I get this to work on my laptop? I actually have serious overheating issues with my laptop CPU where my keyboard fuks up after I have it on for 2-3 hours and types letters twice.

I googled and the first 3-4 results all said "ryzens' can't be undervolted". I can turn on "quiet mode" as a setting but just hugely underclocks the whole thing instead of letting me tweak it.

Why would they not be able to be under volted? lol
I even have my 5600X under volted. Lost zero performance and dropped temps considerably. (Not that they were horrible before, but no reason to feed more power than what's necessary.)

You do it in your BIOS. Go a little at a time and run something like cinebench until it crashes then add a bit back.

No idea why they wouldn't be able to be undervolted. Maybe just some idiots on reddit who had no clue what they're talking about. Anyway, I've done overclocking before adjusting the voltages and clock speeds, but I'd prefer a simpler and quicker solution for now instead of trying to find an optimal setup.

Do you think using some software like Ryzen Controller, setting a max CPU temperature and calling it a day is a safe fix? Again, I'm not looking for the optimal setup atm I just want the keyboard chatter to go away because I have to do a lot of writing for work and it pisses me off greatly.

I know you can do it in the BIOS but give Ryzen Master (Official AMD Processor Software) a look: https://www.amd.com/en/technologies/ryzen-master

Which laptop/CPU do you have brah

I've got a Lenovo Legion 5 with a Ryzene 7 5800H CPU.

Trying to mess around with this software atm:

https://ryzencontroller.com/

Might give the official one you linked to a try.

Edit:



So much for that.

[rocketfish]

I haven't done so, but people have been undervolting AMD cpu and gpu's for a very very long time now. Sometimes they get faster results in those benchmark scores cause less thermal throttling.

I'm not 100% sure but I think i read somewhere that the reason is because silicone is different for every chip so the voltage is like a one size fits all for everyone.

You're not running that ryzen auto OC thing? I forget what it's called.

Never heard any anyone undervolting a 5600x. It uses so little power the possible instability isn't even worth it.

Yes, the standard speed and voltage is what's safe for everything. Most of the time, for a given product stack, lower end models are the same as higher end models but with more failures, so they laser off the bad components and sell them as that lower product. For example a 3080 is a 3090 that had more shaders fails (could be any number down to the specified spec) that are then lasered off to that default spec. It's called the silicon lottery. Some chips OC better than others.

Undervolting can increase performance sometimes due to a lower temp that then allows the boost clocks to go higher due to the increased thermal headroom.

[MiamiLife305]

Yes it is

[OptimusTrajan]

Yes it is

Just do it in bios?

Bios is always better than in your OS.

1.3-1.4 is what a 5600X usually runs at under load.
I’m all the way down to 1.2 still hitting advertised clock speeds and 100% stability. This system has never, ever crashed on me under a CPU load of any kind.

Edit: I don’t use any software to set voltages, etc, only to monitor.
BIOS is the best place to set clock speeds, adjust voltages, etc.

It's hitting 4.8 at 1.2v?

[R3L3NTL3SS]

It's hitting 4.8 at 1.2v?

4.6. 5600X boost is not 4.8. Many are hitting 4.6 at less than that too.

[Barteh]

Bummer. Have you gotten Ryzen Controller working?

Could try this random YouTube video I got working.
[youtube]muYHGjSS7Ls[/outube]

Ryzen Controller keeps the temps down but the options are kind of limited/vague so I'm probably not getting optimal performance. I tried to change some chit in the BIOS but my BIOS is extremely limited and doesn't seem to have any clock speed and voltage options. So I'll stick to Ryzen Controller for now and when I want to do some serious gaming I'll just turn it off.

[nkiritsis13]

The concern/inconvenience I've read regarding undervolting GPUs is bugs, crashes, and/or general instability with games, but how does it fare with undervolting the CPU?

And how's the 7000 series looking? I'm sitting here on the sidelines readying a build and debating on whether I should jump on it over committing to a 5900x.

With the 7950 people are getting temps into the 60's with no loss and into the 50's with as little as 5% loss.

That really is downright mental.

Is it easily replicable? I'm not familiar with AMD's software or undervolting, but it would be smart to add an easy, automatic mode similar to overclocking if one doesn't exist already.

It took me a moment to imagine how that would look, but what brand of cooler do you have? And how's the support with all of that hanging off the CPU?

[Visel]

My 5900x and RTX 3090 actually stay very cool. But I've got a good case, rearranged the fans multiple times to improve airflow, got a good AIO liquid cooler (H150i 360mm), and my PSU is a titanium so it generates zero heat. Therefore no, I don't undervolt.

I do have a gaming laptop where I basically need to undervolt depending on the game and what settings/FPS I want. And even after getting an external fan pad, custom thermal paste and pad solutions, and undervolting, it still throttles due to the temperatures lol (just not as often).

[OptimusTrajan]

4.6. 5600X boost is not 4.8. Many are hitting 4.6 at less than that too.

My 5600x boosts to 4.8 with PBO.

I looked into it, the potential instability isn't worth the miniscule power savings to me.

It's a lian li 011 Evo case and a corsair h150i cooler. 3 fans on front of it and 3 on back sucking air in from the back of the case. I have a 5950x and it never goes above 60 with the fans all set to 1000rpm. Pretty quiet too. It's the 3 fans mounted on the back of the case. The 011 dynamic Evo is a 10/10 case.

How are your GPU temps?

My EVGA 3080 12gb always hit the stock thermal limit of 83 whenever I play any modern game at 4k. Even undervolting to .925-.95 still goes to 83 and I notice the clocks drop to under 2000mhz because of the heat

Ive been thinking I should get a case that can add fans to the bottom and directly cool the GPU

3080ti and i have the fans set to keep it around 80 under load, if I run it manually I turn the fans up to about 90 percent and the gpu will stay around 75-80, a little lower if I crank all the case fans up to assist.

Running on stock clocks


Idk I think it's fine probably. I have a 1080ti in a micro build underneath mine and that bad boy has been running at mid 80s for like 4 years no problem. That case has like zero airflow

I undervolt my 3080 to 925mv @ 2025mhz and I actually get more average fps than when I just overclock and my card never goes over 50c.

3080 is designed to go as far as it can until it hits either thermal or temp limit. By default the 3080 will go to 83c, this can be changed in PX1 or afterburner.

Your card is operating as normal. Boost clock is 1800mhz. It will boost beyond that if power and temps allow. Stock 1965 to 1995 is normal.

You can increase the power limit from 380 to 400 and/or overclock it to go beyond that. My EVGA 3080 10gb does 2070 at 400w depending on the game.

Okay, that makes way more sense because of how the 011 Evo case is shaped versus the traditional tower setup.
