Is your system showing that Dynamic Boost 2.0 is available?  Mine is not.

 

i am also showing dynamic boost in system info (i am with with latest NVidia game ready drivers, that was also listed with Dells signed driver before i changed)

 

 

BTW i have to eat some of my words back, still with Dell's default paste  

500 point higher than my best dGpu score with LM TIM
https://www.3dmark.com/spy/33797525

 

in MSI Afterburner i did not overvolt dGpu memory clock,
only core clock to +275MHz,
 

new cpu FIVR undervolt also changed a bit 
CPU Core           -122.1  (effective -125mV) with  IccMax 185.00
CPU P Cache     -122.1  (effective -125mV) with  IccMax 185.00
CPU E Cache     -97.7    (effective -100mV)

Cache Ratio       8/36 Min/Max 

Turbo Group      all cores set to 4.7MHz

 

only thing missing for me to be happy with the system is a way to peg fans manually to max speed,
and regain the missing 30w TGP, which i have a growing suspicion Dell copied/carrying over default limits from the 7670 dgpu with 125w TGP to the 7770 with 150w TGP, 

[MyPC8MyBrain]

this is quite odd,
ive learned that having iGpu active as in "Hybrid Mode" Enabled is drawing 60w overall at idle, this raises system temps idle at about 6c-7c, switching "Hybrid Mode" off as in working directly with dGpu 100% actually lowers systems overall wattage to 35w draw at idle with 6c-7c lower system temps,
 

isn't that suppose to be the other way around and the whole point behind having iGpu with dGpu? 

[Aaron44126]

dGPU stays on when it shouldn’t. I’ve posted about it lots before. With hybrid graphics on, try just disabling and then enabling the dGPU in Device Manager and see if that fixes power draw and temps. I have this scripted to happen 2 minutes after I log in to fix Optimus.

 

The dGPU might be on even if the NVIDIA status icon thing is showing gray/off. An easy way to check is with Dell Fan Management. If it is showing a temperature for the dGPU, it is on. If it is off, it will show “—“.

i've read that and was unable to replicate here,
hybrid mode on with dGpu Enabled in device manager i am seeing 60-65w total system power at idle,
hybrid mode on with dGpu disabled in device manager i am seeing 40-45w total system power at idle,

hybrid mode off i am seeing 35-37w total system power at idle,

(with all 4 M.2 slots occupied, cool in bios and power saver in windows, 4K, 2xSoDimm)

If the setup_var changes are done to allow undervolting, does that mean the laptop is again vulnerable to Plundervolt?

 

Do the changes stick after a BIOS update?

You need dGPU enabled in device manager to get the power savings.  Doing the disable/enable just kicks it into powering off properly when it is stuck on.

Yes and yes.

bit confused, which condition did i miss?
i described every possible condition and values associated,

When you see the system drawing too much power with Optimus on, disable and then re-enable the dGPU in Device Manager and see if the situation improves.  Doing this action kicks the dGPU into properly powering off.  (It will not fully power off if it is left in the "disabled" state.)

no Optimus for me here

(right above 150 W line, Advanced Optimus = No)

hmm... i did just that!

hybrid mode on with dGpu disabled in device manager i am seeing 40-45w total system power draw at idle,
hybrid mode on with dGpu ReEnabled in device manager i am seeing 60-65w total system power draw at idle,

hybrid mode off i am seeing 35-37w total system power draw at idle,

 

what do you see in HWiNFo64 "total system power" at idle with your current settings?

[Aaron44126]

22W, sometimes spiking up to around 35W.

This is with hybrid graphics on but also I am accessing the system remotely so the screen is off.  (I'll check again when I am sitting in front of the system later.)

 

Also note down in the GPU section I can see GPU Power = 0W.

when hybrid is on i also have most of dGpu values at 0 until an app is using it,

very interesting, how is the screen stays off?

if i close the lid the screen shuts off and makes some application not run properly when i remote in,
it also reverts to full 4k with no scaling and the native screen preference module is none responsive if the lid is closed (maybe its just the software used to remote in, my go to is Dameware, you prob using RDP?),

 

[Aaron44126]

Having the screen on adds about 8W, I am seeing 30-32W power use ("idle" but plenty of apps running) and occasional spikes up to around 45W.

You are right, the lid is shut and I am using RDP which adds a virtual GPU & monitor.

[MyPC8MyBrain]

crisis averted, found the culprit!
i applied the wrong NVidia driver tweak,

word of advice if you use NVCleanstall or manual tweaks
avoid "Disable NVIDIA HD Audio device sleep timer" tweak,

 

 

my total system power now makes sense,
with Hybrid on total system power is 11w with Hybrid off total system power is 17w,

Hello,

 

I'm using Precision 7670 with RTX A3000 12GB.

 

But cannot reach to showing TDP. even CPU limited to 45w.

 

Attached hwinfo visuals taken by after 15-20 mins Superposition benchmark. This is same for gaming too.

 

I need your supports & suggestions.

 

Thanks in advance.

 

And below from GPUZ with another Superposition benchamarked.

we are all experiencing the same issue, each with his specific dGpu and its TGP,
my 3080Ti with TGP of 150w will not use more than 120w (about 20-25% cap from declared TGP),

Thanks for answer, old 7760 with a3000(6gb) is more capable, cooler and quieter, so I'll keep using until new serie's problem got fixed.

 

Btw, applied your suggestions related with ia/dc and undervolting.

 

Cpu side is really powerful but the problem is heat management.

the problem is heat management

100% that still remains an issue for me and every 7X70 owner too,
our joined efforts here help mitigate the heat problem, but far from being able to solve the problem,

i requested from Dell to provide some form of manual fan control to further help with heat issue, I doubt we will see such solution anytime soon, even a simple one like i requested just a toggle that spins fans at 100% until unchecked, no need for fancy fan curve editing etc.,

the way i manage is by running cool power plan in bios and power saver in windows (with S3 re-enabled)
you will see few posts back a PowerShell script i posted that helps switching between "operation modes", for none demanding tasks like browsing internet reading emails or watching 100 YouTube videos simultaneously above cool/power saver combo provides more than enough power while keeping the system very cool,

for performance oriented tasks (for me its executing heavy code workload on dGpu) i use the script to switch modes, if power saver is on it will switch to performance in bios and ultra performance in windows, in 3 seconds I am ready to push heavy workload with all the power available, next time the script runs if performance mode is on it will switch back to power saver mode,

 

 

[developer]

I've made profiles on TS, if I have light workload, I'm disabling turbo, otherwise it is boosting max x42 with TDP 75-90W.

 

But still I'm not happy to hear fan noise. Even in quite mode still kicking after a while.

 

Maybe this is normal but previous gen working very silent even in cool power plan and still providing enough power on dGPU side.

 

Of course 12th gen CPU power is amazing if you can ready to take off noise.

[developer]

I have not so much knowledge and maybe my opinion is not right or not applicable.

 

Is there any option to flash bios of another brand's gpu bios? do you think this will solve?

i tried, it didn't work!

[Mark_Eu]

7770/i9-12950hx/A4500/64GB RAM - without any chanages, out of the box condition.
I will update my bios from 1.7.1 to 1.8.0 in a next days.
Is there any information, or data what i can look out, in HWiNFO64 before/after?
Someone said ac/dc loadline values fixed, i will check this.

[MyPC8MyBrain]

anyone else seeing this odd behavior from Task Manager?

this happens with both OEM image the system arrived with and after a fresh install,
there's an unwelcome delay when task manager starts with a strange black background seen in the video below,
(it is almost mission impossible to search and find useful info on google now days,
every keyword pulls sup mountain of unrelated rubbish articles)

 

 

 

for the time being brought back good old friend i missed,
simple, clean, with no nonsense fluff that occupies half the screen's real-estate,

 

[MyPC8MyBrain]

here is the last response I received from Dell's army of incompetent agents 

after requesting for investigation for the limit on the dGpu
as well as requesting a solution for the overheat in the form of rudimentary fan switch,
after being forwarded from one agent to another over and over below is their final copout,

 

 

 

 

here is a small find i didn't want to report before i heard back from Dell,

someone here is manipulating not telling the truth and its not one of us.

 

 

 

@Dell-Mano_G these are your people?
every Pro Support agent parlayed responsibility until they for the 1000'th time offer me to return it instead of resolving the issue at hand, who's returning me my time and efforts spent on this nonsense? how dare your people try to sale a bug car under false pretense that its a race car?

 

basic economics dictates you can charge on what you can deliver not what you pretend to deliver, 
you cant fully utilize a $2200 sku you don't get to charge $2200 without delivering as advertised.

@MyPC8MyBrain

This GPU limitation on the 2022 Precision 7000 is somewhat obscure.

 

As far as I know, the 2021 RTX has Dynamic Boost up to 15W and this has been increased to up to 25W in the 2022 releases (3080Ti included).

 

The Nvidia control panel reports the maximum TGP of 150W (base TGP + Dynamic Boost) so the base TGP should be at least 125W.

 

@Dell-Mano_G

 

Could you comment on the limitations reported by several owners?

that is starlight up lies from both their engineering and sales department,

engineering responded that due to power limitation they dGpu cannot work at full capacity to its already capped 150w, who's fault is that? why didn't they give it the right power supply to use its 150w dGpu limit? and why they continue to advertise this false information? 
 

either way after informing set engineer that i purchased a 330w power supply followed by removing PL4 limit to allow dGpu to have its full power to run freely that didn't do anything to regain dGpu advertised capacity, not even limiting the cpu to max 30w made a difference to allow dGpu to run at full capacity, the system run with max 160w utilization including dGpu at 115w leaving dGpu extra 80w to himself and still no cigar!

bottom line they had no leg to stand on facing unrefutable facts so they default to further wasting my time, even though i stated it is not just effecting me but an entire community who purchased these,

 

these agents count on us being absolute ignorant for buying Pro support package,
not realizing its the only way to buy physical damage insurance, they assume we are all technical idiots and should accept these lame made up excuses or give up at some point facing an army of support people offering exchange as an easy way to resolve their ticket instead of actually resolving technical issues they caused.
