XPS 13/15 9530, 9550, 9630 can only reach Thunderbolt 2 speeds over Thunderbolt 3 port.

Q: XPS 13/15 9530, 9550, 9630 can only reach Thunderbolt 2 speeds over Thunderbolt 3 port.

I myself own an XPS 15 9550 and noticed that I was not getting the full Thunderbolt 3 speedover it's Thunderbolt 3 port. I expected speeds around 2700MB/s, because of the overhead withthe theoretical gross speed of 3870MB/s, but I only ever got 1400MB/s out of it.
I did some digging and found out that none of the XPS notebooks with Thunderbolt 3 are evenable to achieve the full TB3 speeds, because they are only connected with two PCI Express lanes (x2.3).You can read more about this on the following links:Dell Subreddit PostChipset Digging on Forum

Thunderbolt 3 and the promised speeds were the MAIN REASON I even bought this notebook.I feel very cheated here.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


Because I didn't liked USB 3.0 ethernet chipsets and USB-based ethernet cannot bear some network-intensive tasks, I wanted to use PCIe-based Thunderbolt ethernet controller on my XPS 15 9550. As there is no Thunderbolt 3 "PCIe" ethernet adapter (except docks), I chose to buy Apple Thunderbolt 3 to 2 adapter and Thunderbolt 2-based ethernet adapter.
I plugged it into the XPS 15 9550 (tested with BIOS 1.1.19, 1.2.14, 1.2.16 and latest Thunderbolt firmware with NVM version 16), and the PCIe device did not pop up. Instead, only USB billboard device is appearing saying that "Alternate Mode configuration not attempted". Both Windows 10 and Ubuntu 16.10 failed to detect the device. I moved this configuration to MSI GS63 laptop, and it detected ethernet controller successfully (that laptop utilizing NVM firmware version 18).
It seems that other vendors are affected with lower NVM firmware version involving setup with Thunderbolt adapter: see the case of Lenovo too. Do you have planned Thunderbolt NVM firmware update for XPS 15 9550? Looks like XPS 13 9360 is using newer Thunderbolt NVM firmware version, though.

I'm having issues getting the TB16 to work with the XPS 15 9550. I successfully installed all the drivers in the proper order as documented prior to plugging in the TB16 for the first time.

I've verified that I indeed do have a Thundrerbolt port - there is a Thunderbolt symbol next to the USB-C port.
When I do plug in the TB16 the power button on it will power the system off/on.
I've used a usb-c to Displayport adapter and a usb-c to usb 3.0 adapter with a flash drive. Both worked successfully so the basic functionality of the usb-c port is working.

When I plug in the TB16 I never got an authentication window pop-up. In the Thunderbolt software it shows no attached devices.

The details setting in the Thunderbolt software looks fine, it appears to have the proper driver and firmware levels.

When I check the Thunderbolt driver it says that 'the hardware device is not connected to the computer'.
I'm at a loss - everything looks good except for the fact that nothing happens when I plugin the TB16. I'm wondering if there's a hardware problem with the Thunderbolt controller itself? I'd appreciate any help that anyone can give me.

A:XPS 15 9550 - Thunderbolt port not working - TB16

You might open the Thunderbolt software and set it to allow all devices.  I reset my system and redid the TB16 and it shows the cable and dock as approved devices.
It was not hard for me.  The thunderbolt controller is on the computer.  You show some correct info for that controller, although since I have a 9365, that specific info may be different, but you do show a different controller generation..

There have been several reports of the Thunderbolt 3 port on the XPS 15 9550 (and 13 9350) being configured to a PCI 2x port instead of the more usual PCI 4X port. Users have been reporting speeds of up to 16 Gbps, only half of the advertised speed (40 Gbps) which should be 32 Gbps (with overheads) for data.
The result is significantly TB reduced performance to comparable machines, especially when using an external GPU set up.
If this is not hardwarematically configured as such, it may be possible this could be fixed with a firmware update. Will this be coming?

I recently purchased an XPS 15 9550 with i7, 16 GB RAM, 256 GB SSD, and GTX 960m dGPU that I have connected to a 27-inch QNIX qx2710 2560x1440p external monitor. I have this connected through a Cable Matters USB-C/Thunderbolt 3 to DVI-D adapter and cable.
The monitor and everything seem to work fine at 60hz, except for every time I unplug, turn on, or restart the monitor/computer the first five or ten minutes of use is plagued with constant screen flickering and flashing. After ~five minutes the monitor seems to stabilize and will only rarely have a single screen flicker. 
I have read other forum threads describing similar issues with different monitors/cable setups and that there is likely an issue between the wifi card and thunderbolt port. The common recommendation is to turn down the wifi output percent to 75%, however the Killer wifi card on this computer does not have an option under advanced settings to turn down the power output. Has anyone had any luck doing this on a recently purchased XPS 15 with the Killer wifi card?
The cables and adapters are new and the BIOS and all drivers are up to date. Other than the wifi issue, does anyone have suggestions or solutions to this screen flickering problem?

On the XPS 15 9550, can an external monitor with Displayport inputs be connect directly into the laptop's USB-C Thunderbolt output using a straight miniDisplayport-to-Displayport cable?  Similarly, can a miniDisplayPort to VGA adapter cable be plugged directly into the USB-C Thunderbolt port to drive older monitors/projectors? Or is the TB15 Dock mandatory in order to get the computer talking to  external video devices through its Thunderbolt port output?

Dell just release a new Thunderbolt firmware ,A07
I installed it, and it seems to have destroyed my external HDMI port.
I tested it with different monitors and cables.
On some monitors the colors are inverted (white goes black). Some monitors don't display anything.

I hope the upgrade caused no hardware defect to the HDMI port.
Unfortunately I cannot find the old Thunderbolt firmware to got back.


A:XPS 9550: Latest Thunderbolt firmware upgrade destroys HDMI port

Same. Installed the new firmware successfully, restarted and now my HDMI port is more or less dead. The Laptop still detects the external monitor but it won't output anything.
Tried reinstalling the Intel HD Graphics driver, changing resolution, different cable, different monitor... nothing helps.

Downloaded the newest Thunderbolt driver this morning. It MAYBE fixed the occasional outage problem that many are having with Thunderbolt/USB-C port adapters - jury is still out on that.
Here is what it DID NOT FIX: The fan speed. No matter what I plug in to that port, the fan revs up and stays up. 
I disconnect all USB-C adapters and revert to my USB 3.0 equivalents and everything works fine. I have a 3.0 LAN/Gigabit port and a Plugable 3.0 to HDMI adapter that are working great with no fan revving.
The minute I use my USB-C versions, that fan gets spinning. Why? Watching my Task Manager, I can see 1-4% CPU, 20% Memory, 1-7% disk. There is NO REASON for that fan to be running.
Until Dell and Intel get that Thunderbolt port dialed in, I'm staying on good ol' USB 3.0. At one level, that is frustrating as I bought the XPS 15 partly because of the promise of the "One port to rule them all."

A:Dell XPS 15 9550 Thunderbolt and Fan Speed

I agree 100%. Bottom line is that ThunderBolt 3, at least in the XPS 15 9550 implementation, is not ready for prime time.
Right now I am running with my XPS 15 closed using an external monitor connected to the integrated HDMI port, a USB 3 adapter into which I have plugged my gigabit ethernet, my usb keyboard, and my integrated monitor webcam. I also have my wireless mouse dongle connected to one of the integrated laptop usb ports and have my power adapter connected. Fan is completely silent and everything works perfectly. I should be able to connect all of that thru the TB15 dock using the single Thunderbolt 3 connection to the XPS 15 9550 with exactly the same results. Unfortunately with the current state of drivers I cannot.
I bought my TB15 dock directly from Dell. Their can't be that many of us. You would think Dell would make the effort to make sure that all of us that did would be communicated to and taken care of...apparently not.

I have the XPS 15 9550. I bought a startech thunderbolt 3 dock. It was completely dead - no sign from the laptop when I plugged it in. They replaced it. The new one worked fine for a day. Then it too was dead - no sign that it's connected. It seems unlikely I had 2 dead models. Any ideas whether there is something on the PC that could cause this? BIOS is updated, as is thunderbolt firmware & drivers.

I am trying to use a 3rd party external GPU enclosure that attaches via thunderbolt, and when attached, I got the message pop-up that external GPU support was not enabled by the vendor, and as such the device will likely not work? Has Dell locked the Latitude 7480 down to no external GPU support?

A:Latitude 7480 - Thunderbolt 3 - Thunderbolt software say external GPU support not enabled?

Probably.  I read somewhere that since Dell is pushing their Alienware external GPU stuff that uses a proprietary connection, they never enabled external GPU support via Thunderbolt.

After the time spent with Dell Support doing diagnostics and updating video drivers to those official Dell drivers on the support page, my new XPS 15 9550 with 4K touch display continues to struggle when using external monitors. I have two (2) Dell U2515H monitors.
I have updated ALL of the drivers and BIOS to the very latest files available on the Dell support page, including the newest Thunderbolt 3 driver.
When the laptop is NOT connected to any external monitors, I am NOT experiencing any trouble.
When the laptop is connected to ONE external monitor via the onboard HDMI port, I am NOT experiencing any trouble.
Trouble begins with the addition of ANY external monitor via the USB-C/Thunderbolt 3 port.
I have experimented with the following three adapters, all producing the same result:

Dell USB-C to HDMI (2.0), part number 047KD7
Dell USB-C Port DA200, part number 5KMR3 REVA00
Cable Matters USB-C to DisplayPort
First, regardless of which adapter. my laptop ramps up the fan for as long as the adapter is present.

Second, although the monitor works with any of the adapters at the proper resolution, all of the screens will go black about every 10-20 minutes and the displays will seem to resize and reset. In this process, about half of the time, the windows open on the monitor connected to the USB-C/Thunderbolt 3 port will either minimize or relocate to the primary display (the laptop screen). However, the laptop itself doesn't freeze. I tried running a YouTube video t... Read more

A:Trouble with XPS 15 9550, USB-C/Thunderbolt 3, and external monitors

This is apparently a problem with the Thunderbolt 3 driver/firmware and/or the Intel 530 graphics drivers. I see very similar issues using Dells new TB15 Thunderbolt 3 Dock. Normally when I'm in my home office I use my 9550 with the lid closed using an external monitor connected to the HDMI port. All works perfectly. When I try to use the Dell Thunderbolt 3 Dock and connect my external display to its HDMI port it is unstable. Sometimes the external screen goes blank for a few seconds. When the system wakes up from sleep or I reboot it it does not come up on the external display but I have to open the laptop and switch back to the external monitor. Basically it is unusable. Still waiting for Dell to fix the issues.

There is an issue with the update for the tunderbolt firmware when updating through the system update utility. This is a known issue that the Engineering department has been working on. The only known resolution to this issue so far has been to replace the system board. Im sorry for the inconvenience this is causing. If the device is still under warranty i would speak with the support center to have a tech install a new board.

I'm trying to use the Dell XPS 15 9550 with Windows 10, and I connected two external monitors, one to HDMI, one to Thunderbolt.
Only the one connected to Thunderbolt works, the other doesn't, it simply says no signal.
The cables and the port itself definitely work, if I switch to Ubuntu, both screens work.
On Windows, only the Thunderbolt works, even if I connect only one screen, the HDMI output doesn't work. I tried all combination of screens and cables, and in all combinations it is always the Thunderbolt output that works.
I'm on the latest updates with Windows 10. Latest NVidia drivers. Tried the latest Intel graphics drivers from the Dell site, also the latest ones from the Intel site.
One extra information: some forums suggested checking the NVidia Control Panel, but there I only have the "3D Settings" node in the tree, nothing else.
(I've googled a lot and read all the forum threads I could find, but nothing worked.)

I just bought a Dell TB16 USB-C/Thunderbolt 3 dock for my Dell XPS 9550. I updated the BIOS and drivers for both units using Dell Command Update, but now every time I boot up my computer I get a message stating "your PC may need updates for the Thunderbolt 3 port to function properly. For more information go to thunderbolttechnology.net/updates". That link, in turn, refers me to the Dell page that tells me to do the updates I've already done.
It's annoying to get this message even though everything appears to be up to date. Anyone run into this and have a solution?

I have been experiencing issues with my USB keyboard on my XPS15 9550 w/TB16 Dock when the Logitech G610 USB keyboard is plugged into TB16 USB 2.0 port in the back.
The keyboard will hang, accepting no input. or may hang on a certain letter, thus producing an "aaaaaaaa" across the screen until the keyboard "comes back".
Keyboard seems to work fine while plugged directly into the XPS15 rather than the TB16.
I also have an external USB drive for backups that I use connected to the TB16, although seems to be functioning fine. I have not had a backup fail, so, I assume it is working fine.
I have tried downloading all of the drivers, and re-installing them in the proper order according to the documentation while disconnected from the TB16, and then connecting to the dock.

Is anyone else experiencing a similar issue?  Is it the dock or the 9550?

A:USB Keyboard Hangs/Quits working on XPS15 9550 and Thunderbolt Dock TB16 . W10Pro x64

If you happen to run Citrix Receiver, make sure you're running at least version 4.9, since earlier versions are known to cause USB issues with the TB16, although that typically presents as the USB ports not working at all.  If not, then there was also an issue with intermittent USB device disconnects that was eventually solved through a combination of drivers and firmware, so when you say you've downloaded all of the drivers, please confirm that includes:
- Thunderbolt firmware
- Thunderbolt software
- ASMedia USB Host Controller driver

I have a HP ZBook 15 G3 Mobile Workstation (Engery Star)- Product Number - V2W12UT#ABA. It has 2 USB Type C Thunderbolt Enabled Ports.   Not quite what it is used for.  Can you use a thunderbolt adapter for an Ethernet cable which uses Giga Power and a HDMI Cable, etc.  Basically the thunderbolt adapter would have more than one port.  Am i understanding this correctly?  If so, what product do you recommend?

Again, I have that same laptop and I happen to have in my bag a thunderbolt/USB-C to HDMI adapter and one that has a gigabit ethernet and 3 x USB 3.0 ports. HP also makes a Zbook dock I am using which has a DP and an HDMI, VGA, gigabit ethernet, a few USB 3.0 and a couple extra USB-C ports.  P/N P5Q58UT#ABA There are lots of adapters with multiple functions. Thunderbolt can allow some really amazing number of additional devices to be connected through one port like I believe 4 x 4K monitors.

I'm thinking of getting a P70, I see it has 4 USB 3 ports and 2 Thunderbolt 3 ports.  My questions are: 1: Is each of the USB 3 ports connected to their own controller so that each port is capable of it's maximum bandwidth?  Or are all four ports connected to the same controller so that the data bandwidth is divided among the four ports? 2: Similar Thunderbolt 3 port question.  Is each of the two Thunderbolt 3 ports connected to it's own controller?  Or is the bandwidth shared between the two ports? I'm planning on using the USB 3 ports (maybe Thunderbolt 3 also) with a high end, high data rate USB 3 camera that, according to the specs, can use up 95% of the USB 3 bandwidth.  If I were to use two cameras at the same time, it would not work if all four ports are connected to the same controller/bus and sharing the bandwidth.  I have read that laptops usually share all USB ports on the same controller.  I'm hopeing it will be different with the P70, being a "professional" workstation class product. Thanks

I'm using the thunderbolt port for a single connection to a Dell usb-c dock (power in, KVM out, speakers, network, etc.).  The 720 charges real slow and the battery status message (in Lenovo Settings app) states that the "AC adapter cannot provide enough power for normal operation of your computer".  The Dell usb-c docks are powered with a 180w power supply that provides 60w of power to the computer, which is more than the 45w power supply that comes with the 720.  I have tried 3 different Dell docks, including a Dell thunderbolt 3 dock with a 240w power supply. I have to believe this is an issue with the Thunderbolt 3 driver on the 720 or something BIOS related.  BTW, the 720 has Windows 10 pro loaded (updated from the home version loaded by default) and Bitlocker enabled.  Don't think these changes have anything to do with the issue. I purchased Lenovo's thinkpad usb-c dock (which states that it's universal) and hope it charges the 720.

Hello, Notebook is super noisy and dock wire is way too short to put it somewhere far away. I though may be it's possible just pluging power into notebook and connect docking station via Thunderbolt only but not sure if it will work and if docking station in fact needs external power which thunderbold cable will not be able to provide.

Also, what ports does it have? If thunderbolt 3 port or USB 3.1 ports are not there, can I use some adapter which connects between USB 3.0 and Thunderbolt 3/ USB 3.1 ports?

As the title suggests, is it possible I can charge my Acer VN7-592G through its Thunderbolt port? As far as I know, Thunderbolt 3 allows a maximum power input of 100 watts, whereas the charging adapter for the respective device inputs 135 watts. Nevertheless, is it still possible to charge the laptop through the Thunderbolt 3 port using a high powered USB power bank? I recently purchased this laptop and discovered a dirty little secret Acer included was that once the battery reaches 41% the CPU throttles itself to 0.78 mHz which makes the system very unstable. (Bear in mind, battery saver was off, and CPU was set to High Performance, and 100% max load). I realize the charging process will be very slow, but will the device still charge? I need to know this ASAP because if it doesn't, and the CPU throttling issue still occurs, I will sell the notebook on Kijji, and purchase the Dell Inspiron 15 7559 that has a larger battery, same processor, and doesn't undervolt the CPU when you have 41% battery still remaining. Being charged $1,400 for a laptop that throttles its CPU down to the speed of a primitive Pentium 3 when the battery has sufficient charge is a total rip off.

I received my X1 Carbon 5th Gen just a few weeks ago. Today, a thunderbolt 3 port next to an LED suddenly died and seems to no longer accept any devices. I tried 4K monitor and some other USB devices thourgh a USB type C hub connected to the port, but nothing worked. I tried with Windows 10 and Ubuntu 17.04, the port no longer works with any operating systems. Interestingly, Windows 10 now thinks it's connected to AC power even when nothing is actually connected to the Thunderbolt 3 ports. Therefore I strongly suspect this is a hardware issue. Does anyone have a similar problem?

Hello - I wish to connect my 24" Dell monitor (it has every port imaginable) to my Lenovo Yoga 720 WITHOUT using the Thunderbolt port. Is this possible? I am a Jazz musician and I with to use the external display for (1) reading complicatedf [e.g., classical piano] sheet music and (2) for use with DAWs (digital audio workstations, such as Abelton, Pro Tools, etc., where there is LOTS of info crammed in tight and a large monitor is needed). My Yoga's TB port is used for a 500 gig Samsung external hard drive.  The Samsung houses my music programs (e.g., the DAWs, Ivory piano, Easy Drummer, etc.), and I placed them there for the fast speed (this really helps eliminate the latency on the pianos).  I don't need fast speed with the monitor; my prior Lenovo G780 worked just fine with my 24" Dell monitor; the G780 had an HDMI port. I don't find a "TB dock" that has (1) HDMI, display port, etc. AND (2) another TB port.  Does such a thing exist? I've tried the crappy "USB montitors."  They (1) suck and (2) are not 24". Am I screwed here? Thanks, - Jeff Newton (Jazz saxophonist and pianist)

Thinkpad X1 Extreme Platform Specifications:https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20X1%20Extreme/ThinkPad_X1_Extreme_Platfo... On the above link, Lenove states this device only supports [email protected] on DP output of Thunderbolt 3 port, which indicates each Thunderbolt 3 port of this device supports only 2 PCI-E lanes. But on the other hand, there are some articles claims that X1 Extreme supports 4 PCI-E lanes on each Thunderbolt 3 port. Which is true?

Would like to connect my HP27Q (5K, dual display port) monitor to the new Apple products using Thunderbolt 3. There are several Thunderbolt 3 hubs that provide dual display ports but they only work with Windows. I do know that I can go with an Apple machine that provides dual Thunderbolt 2 ports such as recent iMacs and Mac Pros but that isn't a desirable solution. Any ideas?

Hi,I am trying to hook 2 Dell U2417H monitors via the W541 Thunderbolt/mDP port. I am chaining the 2nd monitor from the 1st using its DP output port. The MST is only enabled on the first monitor as instructed. My laptop has integrated NVIDIA K1100M video card which is capable of daisy chaining.https://www.nvidia.com/content/PDF/line_card/6660-nv-prographicssolutions-linecard-july13-final-lr.p... I cannot extend to the 2nd monitor as it does not detect any signal. I know that my 2nd monitor do work. There seem to be no option to turn on/off MST from my laptop. I don't see where the problem can be. Can someone help? Thanks

I am on a laptop with a gtx 765m. I am trying to connect a thunderbolt port to a display port monitor. My understanding is that thunderbolt is backwards compatible with display port. But, for the life of me I can not get it to work.

I am using a minidisplay port -> display port cord.

I have ended up hooking the monitor up with an hdmi cord for now. FYI the monitor is a 2560x1440 monitor if that matters.
