r/Undervolting

Hi, I have a problem. I’m running an i7-14700K on a Gigabyte Z790 Aorus Elite AX with an Arctic Liquid Freezer III 360 with new thermal paste.

Ever since updating the BIOS to version FM, the CPU has been running way too hot. With the latest version, FO, it’s running slightly better, but under load it still hits at least 85–90°C. I’m not familiar with undervolting and need some help getting my system to run cooler.

It didn't work with YouTube videos. With the settings out of the videos my system ran hotter then before.

I’d really appreciate any help with this.

I got a dell g15 5530 , i5 13450 HX.

I have done nearly everything but still im not able to get that "FIVR CONTROL"

VBS disabled (from BIOS)

Overclocking lock disabled (from grub shell)

Overvolt protection disabled (from grub shell)

Memory integrity off

Still im not able to undervolt man , what am i missing?

When undervolting RTX 50 series, any gpu probably, the sustained effective clocks are lower than the nominal clock set in Afterburner. To my understanding the effective clock delta is decided by gpu temps and load scale/type (PT, RT, light load etc)

Questions:

1. Is it worth it or even possible to tune for a 0 clock delta by tuning to a lower value

2. Is there a definitive chip specific frequency at which the bulk of the performance is ensured for Blackwell

3. Is it better to tune for a frequency while under the heaviest possible load and therefore be prepared for the worst case scenario?

My profiles are as follows

Stock 1070mV @ 3150

885mV @ 2820

925mV @ 2917

965mV @ 3022

1005mV @ 3150

1050mV @ 3217

Under heavy pt loads, effective clocks are 50-150mhz lower, with the delta being larger at lower voltages

I have a 5070 and generally just wanna walk through on what to expect and what under clocking would entail I really just want lower temps when gaming as 70c is ok but freaks me out

Hey everyone,

​Wanted to quickly share my setup and check if I missed anything regarding stability or hidden caveats.

​The Initial Issues:

​Crazy high stock voltages: My ASUS B760-PRIME PLUS board was pumping 1.50V+ VID out of the box, leading to high temps and potential degradation risks.

​IA CEP Performance Loss: Lowering IA AC Load Line to 0.50 triggered IA CEP (Current Excursion Protection) clock stretching. The CPU looked like it was running at full clock, but my Cinebench R23 score crashed to ~11,800 pts.

​How I fixed it:

​Returned IA AC / DC Load Line back to Auto (so IA CEP stops choking performance).

​Set IA VR Voltage Limit to 1400 (hard cap to prevent spikes above 1.40V).

​Applied a negative offset via Adaptive/Offset Mode: -0.050V (CPU Core Voltage Offset).

​Set power limits (PL1 / PL2) to 180W / 200W.

​Current Stats (Air Cooled):

​Cinebench R23: ~25,500 pts

​Temps: Max 81–82°C in R23 loop (~70°C avg), around 60–63°C in CS2.

​Voltages: Max Core VIDs capped strictly at 1.393V under load.

​Question:

Is using IA VR Voltage Limit (1400) combined with a -0.050V Offset (while keeping AC/DC LL on Auto) the standard workaround for un-disableable IA CEP on ASUS boards, or is there any hidden instability/latency issue with this approach? And overall is there something that I didn't do or do wrong?

​Thanks!

As sad as it is i do play roblox with a decent pc but i feel like my pc gets too hot when im playing with half graphics my specs are as listed

Processor Intel(R) Core(TM) i7-10700K CPU @ 3.80GHz (3.79 GHz)

Installed RAM 32.0 GB

System type 64-bit operating system, x64-based processor

Nvidia RTX 3080

My average temps are around 50 C but i feel like they should be lower or something ive done some minor underclocking already with my curves being at 1900-850, if i shouldnt underclock more then id appreciate some tips to keep my room cool during this summer heat with my room being 80 and my ac being at 69-70

Just bought myself a pc specialist recoil 16 amd with a 5090 and a ryzen 9 9955hx3d and i really need help for the cpu temps and im really scared of undervolting,will undervolting cause damage that will render the pc unusable and could void the warranty?

Hello, I have 9070xt pulse and I tried doing some undervolting. I started with -40mv and -10PL, which was stable in benchmarks and gave around the same result as stock, but with 10% less power used. I was playing cs2 and I got blackscreen and notification that GPU drivers crashed so I changed it to -35mv, got blackscreen, and again and again. It finally seems stable at -20mv and -8PL. I feel like something is really wrong, because I see that everyone has at least -60mv with 9070xt pulse. I know it is possible to get unlucky and the GPU could not handle UV well, but come on, -20mv is way too bad. Is there any BIOS setting or something that's not letting me do the undervolt? I hope you can help me!

P.S. I have i5 14600kf undervolted to -70mv, but it has been stable for a month now and I don't think that CPU would crash the GPU drivers. Maybe I'm wrong, that's why I'm here.

i have a ryzen 7 3700x, i used offset -50mv and it seems like the CPU still spikes to 1.5v in single threaded tasks, and even with or without the undervolt it seems like it never hits the 4.4ghz and stops at 4.150 or 4.175ghz

yo guys i bought msi crosshair a16hx
gpu: rtx 5070 8gb laptop
cpu: 7945hx

the laptop sometimes would reach thermal throttle, it would boost to 150% fan speed immediately and dramatically drop fps for 4-5 seconds with maybe a screen blink (maybe after like 7-8 minutes of 95-100% gpu load in CS2). I didnt even know i should put bottle caps under it, i did put 2 bottle caps under back side, but gpu still goes up to ~82 celsius rather quick and as i understand what happens when it reaches 86 or so BIOS says wtf are you doing and does this scary thing to save the gpu from damage, so ~82 degrees seems dangerously close. i would love for the card to run less hot without degrading performance so undervolting seemed like the obvious thing i should do. but the problem is that i have no clue how to do it. and since changing voltage doesnt sound like a very safe thing to do i dont wanna risk it, so i want help from you guys.

how do i undervolt it properly? i tried asking ai around about it and it suggested this:

ai suggestion

heres how original graph looked

original graph

it would be lovely if i could make this card run cooler, maybe faster, and less demanding on the battery, but i need someone's help with this as i dont wanna cook a new laptop and dont have a full picture of how it works yet really. after this i could look into cpu undervolting too, but for now id like to stop the gpu from this scary throttle (is it even normal?)
