Mini ITX PC - Undervolt for BETTER temps & performance

[@DaveBenchmarks]

I did something similar to my 4060 LP. 900mv +255 +500mhz on memory Temps dropped around 15c in a 30c degree room One tip for AM5 users on a budget A620 board. Since these processors tend to run to TJMax and AMD states it is normal, if you are not comfortable with the temps, you can go into bios and change the TJMax to the degree of your choice. Here are my results: TJ MAX 80C - maintains 76C CPU-Z stress test score 5500 TJ MAX 70C - maintains 70C CPU-Z stress test score 5450 TJ MAX 60C - maintains 60C CPU-Z stress test score 5250 The TJ MAX value to score ratio will depend on the cooling potential of the cooler. It is worth trying out on your 5600, hopefully you get even better results!

Undervolt is great, summer incoming so i dropped the voltage down 0.15mV on my RTX2080, around 50w less powerdraw, -600rpm on the fans and still 10-15c drop in both gpu and hotspot temp. The preformance drop is there but you can only see it in a benchmark.

[@JammyMunkyTech]

Perfect for summer 😎

[@dixonmak]

Fantastic info on undervolt the cpu & gpu. Thanks. I was wondering if you will do another undervolt lesson on Intel cpu. Cheers!

[@qwsedxrfctgvhj-gh4lz]

do the undervolting applications have to be opened or running in the background the whole time for them to take effect?

[@JammyMunkyTech]

Yes, but you configure it in the bios so you don’t have to use the apps

[@denisnatera3633]

Def better temps is the way to go nice video bro!

[@JammyMunkyTech]

👊

[@zt2533]

Finally someone with the same setup as me T_T may I ask why didn't you undervolt your cpu in bios?

[@JammyMunkyTech]

I use editing software that might need the extra cpu performance so I just found it quicker to turn off the undervolt in ryzen master if I needed to

[@Raven_614]

​@@JammyMunkyTech just use pbo. No loss in performance (slight gain in most cases) and lower temps and lower power draw for pretty much all tasks

[@JammyMunkyTech]

I'm planning to build a similar pc, but since your video doesn’t show any gameplay footage with the fan noise. I’m considering replacing the CPU cooler with either the Be Quiet Pure Rock LP or the Noctua NH-L9a-AM5 let me know which one of these Cpu cooler is the quietest. My goal is to minimize noise or make the PC as silent as possible

[@dukejukem8843]

Just found your channel. Awesome video. I have a question in relation to undervolting. Is there a "standard" on how to start the process? I usually see people, including yourself setting a curve in afterburner and also boosting the memory clock. I never quite understood how people determined that aside from lowering the voltage, that overclocking the vram would also yield gains. I've always been too intimidated by the afterburner curve graph as I don't fully understand it so I've always just lowered my voltage in combination with clock speeds on my own or else I'd follow someones settings from reddit. CPU undervolting has never been an issue for me. I'd just lower some things in bios and everything was either fine in cinebench or it wasn't. Just curious if there's a "best" way to go about the starting process of undervolting a gpu, aside from just lowering the voltage and firing up superposition?

[@JammyMunkyTech]

I start the process by running a benchmark on the card for 5-10 mins. Find out what the core clock and voltage stabilises at. Note down the figures and use them as a starting point in afterburner. i.e. My GPU was stable at 2535mhz at around 1000mV Whilst running a benchmark, in increments decrease voltage until it crashes, then go back to the voltages previously before the crash and run that for a few minutes. If stabilised then great. Boosting core and memory clock is the same, you'd want to increase increments, bear in mind boosting these would require more voltage, meaning increased temps. It's all trial and error until you find a good balance But like you said, it helps to find out or try settings other people used for the same card but saying that, your particular card can perform differently for what ever reason. So it's best to finding by going through the process.

[@richardfarmer6570]

I did the same when undervolting my GPU, best temps with a small performance hit.

[@JammyMunkyTech]

What card did you undervolt? Before and after temps?

[@richardfarmer6570]

Noctua just released their home series fans, including one for devices. Should be able to put two on top of this case wonder if it would help the temps?

[@JammyMunkyTech]

Yeah I was just looking at that, I might have to try it out

[@mauricedave74]

What fans are those? I have the same case. I wanted to add fans in this case too.

[@klayf_]

@@JammyMunkyTech if you try it, could you please post an update video, I'm curious about how loud the pc will be while Idle or playing video game

[@fishberk]

I'm putting together a build similar to yours for my mother, mainly for work, streaming, and browsing. I'm planning to use a CPU with integrated graphics to keep the temperatures manageable and since she doesn't game, an extra GPU isn't necessary. Initially, I considered the Deepcool CH160 case, but I'm wondering if I can go even smaller. What are your thoughts on this plan?

[@JammyMunkyTech]

A small and thin case would be ideal since you don't need a GPU. I would say go for a case like the one in this video or even smaller

[@fishberk]

@@JammyMunkyTech Thank u. Appreciate your help!

I will love to build this pc i normaly play on ps5 but this looks amaising . Can this pc dongaming and streame at the same time ????

It’s probably possible at low settings, but I would have to test it to find out

Is there space for 1 or 2 Noctua 40mm fans inside? Above the gpu and/or the other side?

I'll give it a try at some point

[@jovieasyrof2017]

beautiful PC, nice undervolting and such an awesome video

[@JammyMunkyTech]

Thank you 🙌

[@gamist8166]

What should i look for to undervolt best? Is it quality power stages on mobo? I prefer losing no or minimal gaming performance, and just wanna keep things as cool as can be for mini itx with high end parts

[@JammyMunkyTech]

Run a gpu benchmark, note down the stable frequency, then decrease voltage in increments whilst running a benchmark. If it crashes, then go back to either the previous voltage when it was last stable or the one before that.

[@patchi8332]

Is undervolting something that's needs to be done everytime you turn on your unit or is it saved and you just have to do it once?

[@JammyMunkyTech]

It’s saved, it’ll load every time the pc is turned on if you set msi afterburner to open on startup

[@patchi8332]

@@JammyMunkyTech as for the cpu also right?

[@MATIvmr]

Can you not slap 1 fan on each side and two at the top?

[@JammyMunkyTech]

sure if you want, on the outside I suppose

[@MATIvmr]

@@JammyMunkyTech yessir that’s the plan although I got a question 🙋‍♂️ if I use a fan splitter to use normal pc case fans instead of USB, will I be able to use them as normal and will need a controller or will they be controlled from bios/ working automatically accordingly to the needs ex temp inside etc? I know it’s dumb question 😂

[@TheCentipede_21]

Can't you use external coolers that are used on gaming phones?

[@JammyMunkyTech]

Could be a good idea 👍

How much does it cost you to?

[@user-mm6hz2wl3g]

I did this same build with your video, except the power supply is a fsp flexguru pro 500w and my gpu is a pny rtx 3060 xrl8. Different ram,mb and ssd, but it is not so important. In my case, what parameters could I use for my 3060? Thanks

[@JammyMunkyTech]

Run a benchmark on your card for 5mins. Find out what the core clock and voltage stabilises at. Note down the figures and use them as a starting point in afterburner. i.e. My GPU was stable at 2535mhz at around 1000mV Whilst running a benchmark, in increments decrease voltage until it crashes, then go back to the voltages previously before the crash and run that for a few minutes. If stabilised then great. e.g. My GPU at 2535mhz was stable at 900mV Or you can try this: kzbin.info/www/bejne/nXmbqmltYpyBeKcsi=ZQXHy8tNpNe8IP2V However is it best to run your own benchmark as every 3060 card may vary in performance.

[@mauricedave74]

This works in all 4060 right? i have almost the same build as you. 4060 and R5 5600. Edit: Just found out that my motherboard doesn't support overclocking. so i cant undervolt my R5 5600.

[@JammyMunkyTech]

Yeah works with a 4060, you wouldn’t want to overclock it anyway in this case, it would get too hot. Undervolt is better for it

[@JammyMunkyTech]

I've never tried an app from amd, so have no idea if you can undervolt. The plastic smell though, are you sure there isn't any plastic wrapping inside the pc case?

[@30shellsk79]

Undervolt only if your cpu throttles or is near throttling otherwise you can lose more than twice the amount of performance without the undervolt.
