eGPU Powerthrottle 2080Ti

Hey Guys,

my egpu throttles around 170-190W, the tpd only shows 50-60% power, but throttles power,
i cant find a solution for this.
Firestrike Extreme went from 14500 to 12000
Gpuscore.
and timespy from 9600 to 7500,

The Gpu has 250-290W for about a second then throttles to 170-190W

Power slider in afterburner is at 111% LN2 Bios, egpu is an Razer Core X, notebook is an early 19 Stealth 8565u with modded Bios 4,1GHz allcore (860cinebench 15)

i really dont know whats the Problem, maybe someone has an idea,

thanks a lot

 

Try reseating the card and the power supply cables to the card. Sounds like it could be a power delivery issue but it's hard to tell.

Also make sure you don't have your power limit set below 100% for some reason in any software that manages the GPU.

 

yeah i also tought about this because i use a 8pin to 2x8pin splitter cable and i heard the lightning Z only uses power from the 8pins and not the pcie slot, ill buy a decent psu and try it.

thanks

 

Had this problem before with a Titan X Pascal not utilizing beyond 50-60% of TDP. Issue was accompanied by maximum fan spin on the eGPU at all times. Problem solved by disabling the dGPU via Device Manager followed by a reboot.

 

update: new PSU same story, intel UHD is disabled since the beginning.

damn im freaking out xD, in GPU Z the intel device is showing disabled or not... maybe there is the problem

 

With 2080ti in alienware amplifier we score 32-38000 gpu Points in fire strike. What is your gpu score? or over 11000 in time spy with 9900k

 

yeah this was before throtteling

so with locked 8565u completely fine, now CPU score is higher but gpu score only 8,5k

firestrike gpu only 26k, but without the powerlimit it will be over 30k for sure

edit:
its a windows issue, when you 3D mark is in background when starting the benchmark its fine only in foreground about 30% slower same with furemark ... damn windows

 

update: same score internal and external Monitor, maybe its my new LG C9

 

Not the Intel-integrated graphic, I'm talking about the dedicated 2060. Disable that in device manager while you have your Razer Core X plugged in, then do a restart.

See attached. I had to disable both dGPU cards in order to force the Nvidia driver to start taking the Titan X Pascal more seriously.

 

i only have the Intel igpu and the coreX, i think im not able to disable the device because in gpuZ there is always a coreclock and memclock showing even the igpu is disabled in device manager

 

Do you have any management software installed for the 2080Ti? What brand is it?

 

only Afterburner, its a LightningZ from MSI

 

Check the power limit in afterburner make sure it isn't set incorrectly. You could also try reverting everything to defaults.

 

powerslider is at max 111% but it has only an effect below 60%, from 60-111% all the same, gpuZ shows only 50-70% under full load,
when the app(3Dmark, futmark) is in background its higher and i got about 20% more fps

 

Make sure vsync/gsync are forced off for the benchmarks in nvidia control panel.

 

That is pretty odd. Can you take a screenshot of your Device Manager with the Display Adapters section expanded?

 

Yeah ill make a ss , found out that the performance is same internal & external display, i think there is my performance loss

*gsync and vsync on/off makes no difference

 

Connect the monitor directly to the eGPU to do any benchmarking. There can be a loss of performance if you are running the benchmarks on the laptop's screen as it has to loop back.

yep i know this, monitor is directly on the eGPU but it makes no difference in benchmarks
maybe its an IntelHD620 bug, when i disable the intel GPU it shows me core frequenzy and usage in GPU Z even if its disabled

 

It shouldn't matter but do you have the latest intel graphics drivers installed?

 

maybe there is some issue with, windows installs a driver from 2018 first, when i want to update via Intel it shows that i have to get the driver from razer, driver from razer is from April 19, and the newest is Nov 19 but i have to install manually via device Manager idk wich driver is the right one

 

i tried the gpu on my desktop, the problem appears its a bad thermalpaste application from MSI side, i only had LM at home but results are really impressive
