Dell XPS 15 9570 benchmarks + temps

Hello everyone.

My Xps is 8750h 9570.

I want to undervolt dGPU.
I used MSI Afterburner. I found a voltage - 0.900v and 1700mHz.
But when MSI Afterburner is opened, my CPU runs at 2000-3000 mHz. And it has temp 40-45C. When i closed MSI utility CPU runs at 800-1000mHz with 30-35C.
What is my problem?

 

MSI Afterburner tends to keep the CPU awake for some reason. Best option is to just start MSI afterburner whenever you plan on using your dGPU for something. And close it again when you are not using the dGPU. It won't cause 'extra' heat, it just causes higher heat when idling.

 

Thaks a lot!

 

Hy,

I need some advice, because I want to buy a new XPS, but I am worried about the temps and fan noise.
So sadly only the hot 6 Core i7 version available with with 1050ti, but that is super hot for this thin laptop. Is possible to disable few of the cores of that CPU to get cooler temps and higher clock speeds? 3 or 4 Cores would be awesome at 4GHz.

 

TL;DR It should be possible, at least, on a few i7 and i9 models I tried, but it is unknown if it helps to mitigate throttling issues.

I've checked a Precision M5530 with i9-8950HK (sort of, XPS 15 "Pro" version) I had around here and, indeed, it seems to be possible to specify how many cores you want to be enabled.

You can choose between one to six cores, though it doesn't affect the LLC (aka L3) cache size as you can see in Task Manager, so you would still need to undervolt it to some extent.

As you can see, the system just booted into Windows and it runs at 4.8GHz. Actually, I think, it was the first time I saw Thermal Velocity Boost (TVB) in action on this machine.

Anyway, I wasn't sure I have seen this option before, so I decided to check a Precision M3510 with i7-6820HQ. It appears it also has a Multi Core Support option in BIOS where you can choose between one to four cores. Unfortunately, I don't have any XPS around so I cannot tell for sure if this option is available there as well. I also didn't perform any tests so I am not sure if reducing the number of active cores helps with throttling.

 

It does not need option in bios, also possible to disable cores on Windows level. I m unsure how is that working in Windows 10, but in Windows 7 —> run msconfig—>boot tab—>advanced options—>Number of processors. There select 4, than reboot!
If you have 6 Cores laptop, use “just” 4 Cores and your system will become snapiier due to higher clocks and maybe less warm too.

 

But if I recall correctly it is in the bios as well.

 

I noticed when running realbench the temp (next to PKG POWER in throttlestop) fluctuates wildly from 78 degrees to 98 degrees. This immediately changes the power limit from ~56W down to ~30W and clock speed from ~3.6Ghz to ~2.8. However it fluctuates like literally every second, going 2.8 to 3.6 and back, with the temps going 78 to 97 and back every second.

WTF

I've undervolted and that's it, no physical mods or repasting. TBH I read all the articles and I'm still confused at exactly which parts are the VRMs lol.

I checked all the sensors visible in HWINFO and I can't find anything, where do I look to find the culprit? ITs not the CPU temp or the PCH temp or the DIMM temp.

Oh and I get around 5000 worse points when docked with thunderbolt. haha

 

So I’ve got this beautiful laptop and yes the bios really has the option to disable CPU cores. The bios is amazing, so many details, i give five scores at this point for the laptop. So changing 6 CPU cores to 4 Cores seems I ve already higher CPU clocks and less temperature, but further tests will be needed.

 

This weekend I opend my 9570 - I9 for the first time because of loud fans and thermal throttling.

original from Dell, 1.5 years old.
!!! cpu with no paste left



after apply of new paste
now no more TT

then in XTU:
undervolt -100mV
limit to 4,2Ghz @1core and 3,4Ghz @6cores
@Full-6c-load cpu temperatures < 72°C and quiet fans (FEM calculation)
rare fan action while browsing ore standard office work

 

additional information:

HT off
6c: with one of my special FEM software (multicore support) I get about 25% faster calculation results when I deactivate HT Hyper Threading in bios.

with new paste
1c: with one of my special FEM software (single core support ) now I get continuous > 4.4 Ghz for 5h (XTU -100mV without multiplier changes)

I wanted to go with a precision 7540, but now
my 9570 can stay with me longer

 

New bios is out... Version 1.15.0 (14 Jan 2020). Be aware it could potentially come with unwanted behaviour. See the thread... Intel XTU and ThrottleStop no longer working to undervolt Xeon E-2186m after firmware updatee

Please report (post) if you see undervolt no longer working in my thread...
BLACK LIST. Adjustable voltage control/turbo ratio limits are locked out due latest Win Update/Bios

Thanks.

 

Hi,

I own the Dell XPS 15 9570, i7 8750H 32 GB Ram, 1TB Nvme SSD, GTX 1050Ti-MaxQ. I am still fairly new to this stuff, but I noticed that my performance is not as it used to be. The first time I bought it, it crushed games. I don't game much, I mainly play League of Legends and CS:GO. However, I did notice that my fps were dropping every now and then and I started to get annoyed. I've been reading from a lot of forums recently, and I see that people have been suggesting undervolting. I have downloaded throttlestop, msi afterburner and kombustor. Initially, I just followed people's number so I undervolted at -125mV on my core and cache, I tried some other things like undervolting my iGPU. I'm a bit of a perfectionist, but a noob at undervolting. It frustrates me that my laptop is not performing to its maximum potential. Many people suggest different things, some even suggest overclocking teh dGPU which honestly confuses me. I also noticed from a lot of reading that there is a stupid cap on the dGPU's temperature at 74c. I tried to undervolt my dGPU on the MSI afterburner, a flat curve around the base clock. However, after all of this, I still don't know if my undervolt is stable. I am seeing better temperatures, but I would like to ask for help from you guys since this forum seems to have XPS 15 owners still discussing how to mazimize performance in 2020.

TL;DR

I need help with my throttlestop settings and undervolting my dGPU. I want to know how to test for stability, what my speedshift settings should be and what to set my Turbo Boost Power Limit settings.

Some have suggested undervolting CPU which I have done, some overclocking dGPU, some capping the power that goes to the CPU. So, I would like to know what is the best I can do to improve the performance of my laptop and stop it from throttling.

I intend to only adjust settings of my internals and I'm not interested in using thermal pads, or thermal paste, given I don't play very intensive games (League of Legends, CS:GO). I'm also not big on disabling turbo, because I feel like I've been scammed.

Thanks for your time!

 

Hi, I'm very late to the party but I guess I finally found the courage and insight to mod my XPS 15 9570. I've been reading through the forum but for some reason I'm slightly confused. I want to try out the iunlock Mk5 mod done by @custom90gt. But I'm slightly confused while reading for some reason, did @custom90gt cut the stock copper liner and levelled them out as iunlock did in xps 15 9560 or was it just the aluminum heastinks and the thermal pads connecting to the backplate of the case? I would appreciate anyone who could answer this in 2020. I'm bored because of Covid-19 and I thought I'd give it a shot as I have finally gained the courage to open up my laptop.

 

For the last (and best according to my testing) revision I did NOT run the copper sink, I just did the five pictured VRM heatsinks and used thermal pad to connect them to the bottom panel. It's the easiest of all of the revisions.

Here is my poor instructions:
"only the VRM near the first ambient sensor padded (5 total) and their heatsinks sinked to the bottom of the case. Ram with thermal pad to bottom cover and PCH with heatsinks and thermalpad between the sinks and bottom cover."

You can see on the first page which 5 vrms had heatsinks.

 

Ah, I see. Thank you so much. I will work on it once I get the heatsinks delivered. Also, @custom90gt did you use electric tape for the PCH, I'm assuming to ensure a better seal?

Another question. I've seen many people say that connecting thermal pad to the backplate can make heat build up more and make things worse and some are doing this thermal pad bridge instead to their heatsink. Any thoughts? Thank you for your time.

 

Can you please help me on how to pad the menory or what area of the memory needa to be covered ? Thanks

 

Hi abujafar,i am going over these mods now and i am having trouble identifying wich ine si the dimm sensor that throttles when reaching 63 degres. Cous you give me a hand with that ?

Thanks !

 

I used 2mm thermal pad over the ram itself, basically covering each stick. There is also a very small sensor between the two ram modules (if I recall correctly) that you could add a thicker thermal pad to so it doesn't register as much heat. I didn't do this, but other users had success with that.

 

thanks, @custom90gt that was such a fast reply after a long time, I appreciate it a lot!

I believe I removed thermal throttle for my computer ( i use it for c4d and 3d rendering and photoshop and illustrator, but the power throttling is still an issue after I repasted and stacked thermal pads in the same way you did on the first page of this post. have any new improvements been made since then? I read all the pages in this post.

I saw you guys also talking about the new disable and lock turbo power limits option in throttle stop (Screenshot attached), but i didn't understand what this option does, would you mind giving me a hint?

my other checked settings in throttle stop are:

clock modulation: 100%
speed shift - epp: 75
speed step.

all the rest is unchecked, if you can please let me know if this is correct or I am messing stuff up unknowingly, thanks!

 

Power throttle can't be overidden but you can use Intel Power balance setting to shift max power to either CPU or iGPU on-demand. If its a CPU heavy task set CPU to 31 and GPU to 16. You can find it in TPL. In the same window, if you see Clamp option checked off or ticked, un-check that, reboot and try checking if you're getting Power throttle being flashed in HWINFO or in TS.
Also, try using a bigger Dell power brick like 230W and see if you're seeing power throttle when running the same c4d tasks.(Not Sure if Dell removed battery boost tech from XPS or not!)
Also, have you tested the undervolt is stable when CPU and iGPU are stressed to 100% for longer than 15mins and doesn't black screen or reboot due to insufficient voltage?

 

hi! i am not sure what those settings you mention do, the settings are as attached?

in c4d is mostly GPU intensive ( as i use octane render) but sometimes i need the cpu to run simulation and other calculations. so i am not sure if that is what i need?

2) not sure what a power brick is?.

3)it is usually fine and i work on c4d for hs. sometimes i do get a blue screen error tough.

 

The settings look fine.
Do you use nvidia gpu for octane? If you intel iGPU when using on battery its best to set power balance to 50-50% vales like 16 for cpu and gpu.
Usually AC adapter/charger is called a power brick.

 

yes, i have to use the nvidia gpu, is very gpu intensive, i dont use the integrated intel gpu for anything of what i do for work
