XPS 15 9570 Owners Thread

The XPS 9570 is full of bugs. Maybe they solved only one important bug but the other 100 are unsolved. I suggest to read the previuos posts with the list of bugs. The Dell customer care is a joke, they only suggest or try to uninstall and reinstall drivers to solve the issues. IMO the bios in this Laptop is very bad (see the issue with fans control) and also very slow... For now I suggest to buy other.

 

Well the battery is a strong point for the XPS. It's also the size of a 14" laptop which is nice.

The 1050ti is orders of magnitude faster than an MX150.

 

The UX392 doesn't have TB3 afaik if you're planning on using an external GPU for it

 

I saw a Reddit post today. It made me question my mind but also broke my heart.

Topic was: " XPS 9570 Overheats when asleep"

"I close the lid (and have the action set to sleep) then I throw the laptop in my bag. When I go to take it out its always very hot. I open the lid and it turns on and takes me to the login screen

It seems to be sleeping fine but overheating for some reason."

Answer by Dell Customer Support:



I feel empty now inside.

 

Oops you are right…

 

New BIOS out, reddit says it does nothing. lol

https://www.dell.com/support/home/a...d&oscode=wt64a&productcode=xps-15-9570-laptop

Fixes:
- Fixes the BIOS recovery function issues.

Enhancements:
- Replaces Absolute Software service from Computrace to Absolute Persistence Module service.
- This update integrates the BIOSConnect feature into Dell SupportAssist OS Recovery. This feature connects the system to the Dell image server to download and recover the operating system.

MY RECOVERY IS A WIN10 USB YOU NITWITS FIX SOMETHING. The fan curve. 74 degrees. I don't even expect S3 or DPC latency but just the fans and/or the temp limits shirley that isn't that hard to fix???? LOL

Updated | The Dell XPS 15 9570's DPC latency issues are more complicated than the company first thought Notebookcheck.net | Feb 26, 2019

Almost four months on since Dell announced that it would soon fix the DPC latency issues that have caused audio problems for some XPS 15 9570 laptops, Frank Azor has conceded that there is no end in sight for beleaguered owners. While he claims that Dell is making progress, he still cannot give a timeline for when the company hopes to release a fix.

Maybe a reason they haven't trown out a refresh of the XPS model this year? If they had, the owners of current models would then feel screwed.

 

@Papusan No. Only reason is 1650(ti) isnt out yet, nor are 9th gen Intel CPUs (I wonder, if it's true the 9750H will have 8 cores, how that should work... mostly throttle under the 8750H). Thats the only reason. Also the new OLED display option has to be ready for it. I think 9570 owners are doomed. After about 1 year, Dell in general wont fix anything major anymore on a product of theirs, wont provide any updated drivers anymore, expect for security updates, that Ive seen for the 9550 an 9560 too. Someone should sue them, and then when the 9580 is out, owners of a 9570 should get an option to replace for a 9580 for free. Would be hilarious if the 9580 had S3 support again.

 

If they wanted... And many brand continue push out 8th gen cpu's for new models.
Frank Azor from Dell confirmed and disappointed: XPS 15 without RTX 2060

 

@ Papusan Not sure what you want to tell me with that? And? Of course it wont have a xx60? Just idiots every year think it would have a xx60. Of course it wont and cant have one. The 50er are the only option for it from a cost and thermal point of view.

 

Most likely 8 cores without HT.

Edit.
Rumors... https://www.notebookcheck.net/Detai...9-9980HK-to-be-the-flagship-SKU.409696.0.html

Yeah, 10W higher TDP will make the model perform worse. Is the 1050Ti Max-Q 75W design? If so, 5W less than the weakest variant of xx60. But a much larger die is easier to cool .

 

What is this about the 'report that modded drivers solves tge dpc latency', surely this is not the case. Or is it? It's been a while since I tried Kevin's driver, but I would be surprised if it should fix the issue, since the issue doesn't seem to be routed in the realtek driver at all (dpc is the same with no driver installed and audio interface disabled).

 

On the 9550 & 9560, completely deleting the nVidia drivers SOMETIMES improved DPC latency significantly. Sometimes it did not matter.

Disabling c-states in BIOS toggle sometimes helped. Of course, with disabled c-states, the geniuses at Dell chose to cap max CPU speeds.

The persistent Waves audio is buggy and should be removed in all cases (if possible lol).

Somehow Dell (or M$ or someone else) more or less sorted DPC latency by accident on the 9550; well, good enough for me for now. That seemed to be dumb luck. Especially as the XPS and CPUs are essentially similar for three generations whilst Dell still struggles to get to the bottom of DPC latency issues of the 9570.

If Dell had spent a bit more time beta testing the original 9550 platform before release, I feel the 9570 would not have these issues and would be a much better laptop.

Maybe Dell will redesign the XPS from a clean sheet when Intel releases a major upgrade to mobile chips, hopefully with the 9590, but I'm not so bullish.

 

Interesting to hear that about the 9550 (Can you post a latencymon screenshot?)

From my DPC latency experience on the 9570:

Comepletely deleting the Nvidia drivers makes no difference.

Disabling C-states makes no difference.

Disabling and uninstalling realtek soundcard and drivers, no difference.

Install/uninstall Waves Audio, no difference.

Either way, if it only work sometimes, it's not good enough.

 

I had this issue with my 9550 and I honestly have forgotten how I got it resolved. Bios update or power plan settings fixed it.
I would go back to my apartment and the laptop would be all fans blazing and

Waiting to see what the 9580 will be like, if it's another no then I'll be gladly keeping my 9560 for yet another year

Photo below is a year old (probably with nVidia drivers uninstalled, waves uninstalled, antivirus disabled, wireless off. Maybe c-states disabled but can't remember).

The nVidia and waves stuff keeps self-installing and I am tired of constantly uninstalling so latencymon results are probably a bit worse today .

 

@pascaladjaero Those are two totally different not related issues. S3 (9550, 9560) wake up problems from sleep can be fixed easily in a few minutes via proper powercfg config, removing all wake up timers and wake up devices, most people just down know how to do that. Modern standby (9570) problems cant easily be fixed, or even configured (all powercfg settings are redundant, thx MS).

@ pressing deactivating c-states, Nvidia dGPU, wifi, AV, ect totally drives buying a Windows laptop (especially this one) for music production ad absurdum.

There was actually a workaround for the DPC latency spikes you could do with Windows 7 (or even 8) by switching from ACPI to old power management, and that resulted in amazing low DPC values. I have an older Acer laptop with Windows 7 for that and music production actually, where I have a MIDI keyboard connected to it.

 

What was that ACPI trick in Window$ 7?

In Window$ 10, this guy claims that after deleting Intel dynamic platform and thermal frame work driver, he can turn off ACPI battery

He seems to have gotten excellent DPC latency results following his steps on a Dell G5, albeit the laptop is rather crippled now.

 

@pressing In Windows XP and 7 you could switch from ACPI to APM (old power management), by going into device manager clicking on "Computer" => "ACPI based PC" and chose the old APM driver ("Standard PC"). It was a bit "risky" (could lead to frozen system or BSOD during boot), because if you do this and reboot, Windows will rewire ALL devices again (finding them one by one via PnP) by routing them differently internally (IRQs were now halfed and shared differently (best if one device has one IRQ) than compared to ACPI). By doing this, you would have amazing low DPC actually. This mostly wont work anymore with Windows 10 obviously, I just looked and Windows 10 doesnt even have a APM driver anymore build into it. So Windows XP with this "trick" was kinda the best Windows OS for music production. You had like half the DPC compared to ACPI and no spike whatsoever.

 

Well, that's still nothing compared with what Bagdad Bob (Frank Azor) has claimed over the years. These days I just assume the opposite of what he is saying.

Another disappointed owner checking in. Unless they fix these issues in reasonable time I will definitely not buy another Dell, regardless what kind of device it is.

I've never upgraded my BIOS, because I read about the throttle downgrade before I continued. I am currently at 1.3.0 and wondering if I should upgrade or not.

I currently have these issues on 1.3.0, and is using Windows with all the Dell bloat apps installed (I plan to do a Windows reset)

• Laptop becomes completely unresponsive a few seconds at random times combined with coil noise at the same time. This occurs perhaps once every one or two hours.
• Coil noise sometimes occurs without making it unresponsive
• Fan noise and heat (undervolting helped somewhat)
• Suspects the laptop doesn't go to sleep properly, I hadn't used it in a few days and put it away in a bag, I found it warm and discovered it was on. I must test more though to make sure.
• Audio device has disappeared after resuming after sleep, has happened maybe 5-10 times.
• While connected to a 4k Samsung TV via HDMI, audio switches on and off every 5 seconds. Also a bit unstable signal as the screen kind of disconnects sometimes. I must investigate if the cable is the issue.

This is the current temp limits:




I've know the temp limit was previously 78, and mine is 75. I have an relatively old BIOS, I thought mine was 78 until today. Which bios has 78?

And would an upgrade fix some of the issues?

 

Mine, BIOS 1.2.2:


But dGPU throttling anyway, even with temperature max 70C.
My dGPU core speed is around 1550 Mhz without UV.
With UV, 0.897 dGPU keeps rock solid performance on 1830 Mhz (with little OC).

 

@Original Poster Welcome to the awesome world of the 9570. Youre doomed with 1.3.0. The last one with 78°C was 1.2.x, and you cant revert back from 1.3.0. So you can upgrade to 1.6.0 anyway. I dont recommend anything >1.6.0 because of the fan changes, or you will hate this laptop even more.

 

You can go back from 1.3.0 and 1.3.1 to 1.2.2.
"Since 1.4.1 has Boot Guard updated, once updating to 1.4.1 or later BIOS, system can't roll back to the BIOS earlier than 1.4.1."

 

@custom90gt Oh... I thought that was in the same version. Well than he could try rerolling to 1.2.2 or 1.2.1, if he's unhappy with the 75°C throttle. However... this is all just a mess. There is not really one bios I would wish to use or advice to use. Every single one has a major flaw. And now stuck with 1.6.0... I doubt they will ever change the fan policy back. I kinda think of getting rid of the 9570 somehow and then maybe hope for a 9580.

I actually found out, that the fan triggers under Windows happen about 30-50% less with the old non DCH version of the Intel driver. Happen still for right clicks on EXE files, task manager and so on, but not for video opening and GUIs scrolls.

 

Interesting about the non DCH version being less prone to causing fan triggers.

You're absolutely right and Dell's 9570 bios is a total mess. I sent 3 back to Dell because they refuse to change the throttle set point. I was hoping that the very threat of me sending 3 back would help but they didn't bat an eye at that, lol. I loved a lot of things about the XPS (screen, battery life, and tweaked performance of the cpu) but also hated a few things.

 

@custom90gt It is not the fan triggers, but the older non DCH version seems to trigger less dGPU polls. I actually have HwInfo run next to using Windows, and have the dGPU temperatur graph open all the time for monitoring short dGPU polls. Everytime there is a short dGPU poll (which should never ever happen of course), there is a reading spike, and then it looks something like this:


Clicking around, right clicks on exe, opening task manager, opening a video with MPC, opening Edge, using Chrome in a fast way tabbing around ect. Then it kinda looks like that, with the newer DCH Intel driver. Every short spike triggers a fan with bios =>1.7.0 guranteed for 9 seconds, even the poll was just a few hundred ms and temp were like 38-44°C.

Switched back to the non DCH driver, version 6287, and the dGPU polls happen way less, about maybe 40% in total.

 

Was it on, or just sleeping in the modern hot way?
If Modern Sleep... Unfortunately it doesn't appear to be bag-safe. You can look up the registry hack to disable Connected Standby to get S3 sleep back if it works for you. Or you can use Hibernate instead.
If on... Check if it is configured to switchover to Hibernate after a preset time (Hibernate After in advanced power profile settings), or due to battery charge level threshold. The switchover might fail, resulting in wake instead. See Event log etc.

 

Disappointed but not surprised to see that this laptop is still a nightmare. FFS, Dell.

I mentioned Dell and the XPS for one of the points this video I did yesterday:

 

I just received my new dell xps 9570. Wow, the bios is so unbeliavable, so many options. But Windows 10 is just terrible on it, ugly and i’v got this 3DMark score straight out of the box,


I will try to install and hack drivers for Windows 7 for to terminate Windows 10 problems, hope I will manage. Otherwise it will be shame to sell this beautiful laptop.

 

@Atom Ant ...

 

Just noticed this poping up but havn't seen anyone here mention it?

Dell XPS15 9570, 1.8.1 System BIOS

 

It has been mentioned. Not much new.

 

News on DPC issues from Frank: https://twitter.com/AzorFrank/status/1102923067540598784

To early to get ones hopes up?

 

I believe it when I test it.

 

Is xps 9750 capable of playing 4K Netflix?
Win10 1809 with HEVC codec installed,
Netflix Ultra HD plan, playback settings on high.
Still i cant watch 4k content on Netflix app or Edge.

 

Don't waste your time because once you install Windows 7, you won't get any updates whatsoever when the OS detects that you have an 8th gen CPU. even if you have an older 7th gen CPU, you still won't get any updates, a silly move from MS, but its a reality, unfortunately, that's even if you manage to get all drivers working in Windows 7.

 

XPS DPC latency questionnaire from Dell posted at Reddit
https://www.reddit.com/r/Dell/comments/ay0ows/hi_my_name_is_nelson_mak_and_i_work_at_dell_as_a/

 

That would work until 2020, however I am ok without filthy updates. The bad thing is, that it is not booting windows 7 installer from pendrive, a blue screen error prevents to install. I will try a workaround, but I need to wait for a component.

 

Yes, please fill it out!

 

Guys,

I just purchased a 9570 with the 8750H, 16 GB RAM, 512 GB SSD, 1050ti, and FHD Screen. I purchased it open-box from Best Buy with a 14 day no questions asked return policy. $1200 after tax.

I've noticed in my two hours of using it:

-Fans spin on and spin off every 10 seconds from 0 to max RPM
-Fan noise sounds like it's vibrating
-Just a tiny, tiny bit of light bleeding in the bottom left of the screen
-The battery max capacity is 95% of the originally designed battery capacity

It seems as though whoever returned this laptop used it for two days in February and returned it, from the battery diagnostic I ran.

I updated the BIOS and everything, still no go.

Return it? Is this how all these laptops are?

 

I would try bios 1.6, I think that's the one with better fan profiles. The battery capacity is often weird on the XPS. I've had brand new ones that say 10% wear.

 

@ TSE There is a default wear level of 10% set in bios, you can disable it if you want to, but I wouldnt advice. The fans are terrbiel since bios 1.7.0 and Dell has no intention so far to fix/revert it, so unfortunatly, 1.6.0 mostly will be the last ever usable bios for the 9570, read about it here, and also make a ticket at Dell about it. If they lie to you as usual "were sorry to hear, we never heared about it or have no tickets about it", threat them with the source and tell them if they lie to you again, you will request a full money back.

But even with 1.6.0 the fan profile is bad because it is triggered by both SSD and PCH temperatures, which the fans cant cool. So you have to thermal pad these. Then also short turbo boost jumps of the CPU can trigger the fans for no reason randomly. A solution to this, next to padding the SSD and PCH is, to disable turbo or cap frequencies to around 3.2 or 3.3 under Windows and undervolt.

https://www.reddit.com/r/Dell/comments/akngpy/incompetent_dell_devs_answer_to_bios_170_fan/

 

The rattling fan is a reason to return. You will need to rma to get that fixed.

 

After wiping my hard drive & reinstalling Windows completely, the issues were essentially eliminated. The only thing left is the "coil whine" - as long as it doesn't cause longterm problems, I think I'll keep it. I'm falling in love with this computer's size, weight, and battery life. Even the 1080p screen is really, really nice.

The only thing I'm a little concerned about now is the thermals - I ran cinebench and even after undervolting, the processor is getting to 95 degrees celsius. Thinking about repasting and installing some thermal pads in it following this guide:

What do you guys think? Thanks for the help so far.

 

A question about graphics drivers: Do you guys use the intel UHD and Nvidia drivers from dell or the ones from Intel and Nvidia? I myself have been running the non-dell ones for a long time without any issues, but I'm wondering if I'm missing out on something (performance, optimization, battery life etc.)

There is a new Nvidia driver out from dell along with a "Nvidia Graphics application", whatever that might be.

 

For Intel I use the driver from Dell because every time I install the last driver from Intel then Windows Update downgrades it to Microsoft version...
For Nvidia 1050TI I use the last version from Nvidia (DCH version).

 

Why the DCH version, if I may ask?
