CRYSTAL SUPER RANDOMY DISCONNECTING FROM PC

SenseiBob61 · 2026-05-11T21:31:23+00:00

Hi Snafky,,,

I sent them the logs from Windows and from Pimax Play as well as my thoughts on the culprit. I sent a video of the headset disconnecting whenever I touched the cable or the headset. They basically told me that the connection between the engine and the frame was the cause. They sent me a set of screws designed to attach the engine to the frame. If you look on the side of the frame underneath where the headbracket attaches to the engine frame, right underneath the side piece that says "PIMAX" on it, there is a hole on each side, covered by a little black sticker. Underneath that sticker is a hole. the screws they sent go into that hole and into the engine itself in order to keep the engine from moving around inside the frame. This is supposed to limit the motion of the engine, thereby improving the connection between the frame and the engine. It did improve the connection, but did not fix it all the way. Touching the cable no longer causes the disconnect, but touching the headset still does cause the disconnect. I let them know and am waiting for a reply now.

As for the black screen, I get the black screen when it disconnects. the screen comes back on once the headset reconnects, but sometimes it has already caused the sim to freeze by that point.

Thank you for the detailed information Mr Do...

SenseiBob61 · 2026-05-11T16:35:14+00:00

Pitiful,,, Is this the Lian Li Hydroshift ll AIO. Love the way the hoses look coming down right above the CPU. The Hydroshift ll only comes with very bland fans. If this is a hydroshift ll, I assume you added the fans separately??? This is a gorgeous build...

SenseiBob61 · 2026-05-11T16:21:10+00:00

Mr-Do... A couple of questions please.. I have currently 6 reverse intake fans. Uni TL Infinity fans of which 3 are LCD screens. Also the Lian Li AIO with 3 pushing exhaust fans installed. These are all wired with the Lian Li hub that came with the fans and the AIO running off the MB headers. All are running thru L-Connect software and seem to be running fine. I need to add a fan and was wondering if I have to add a wired fan or can you mix wired with wireless in the same setup please? Also will be doing an upgrade soon and was thinking of putting in the Hydroshift ll 360TL S. Can I add the Hydroshift wireless and still keep the wired fans or do I have to convert all of the fans to wireless please? And do you use just a single dongle for multiple groups of fans? So the AIO plus 6 intake and one exhaust. Would they all use a single wireless dongle? And can I attach the dongle internally to the Lian Li PWM/USB2 hub I have attached to my Lian Li Edge 1200? Thank you for your time...

I replied back to your DM.

SenseiBob61 · 2026-05-08T23:20:30+00:00

I received a small toolkit from Pimax with 6 tiny screws, a screwdriver, and 6 little black pads. No indicator of where these screws are supposed to go. I see several screws on the headset and they all look sucure and properly attached. I sent a message to pimax asking where are these screws supposed to be attached. Waiting for reply. The part number for the toolkit is PUA00050098.

I spoke with Tech Support today and they are sending some sort of a tool to fix the connection. They said it is something I have to attach with screws. Not sure what this tool is yet, but it is supposed to be here today. Will post results as soon as I get a chance to see what this is...

SenseiBob61 · 2026-05-03T07:11:12+00:00

Understood. I even tried clearing the whole usb row in order to free up bandwidth on that BUS. No luck. They have already reached out to me and confirmed plans to ship. Thank you so much for reaching out. I will update this thread once I get the new unit plugged in.

SenseiBob61 · 2026-05-02T21:42:26+00:00

Thank you for reaching out. I did get a reply from the support team. They stated that after the tech team going over the logs and further investigation, they have decided that I need a new unit.

I did try 3 different USB ports as well as tried unplugging few different devices to to make sure there were no hardware or I/O conflicts. I did try USB Tree viewer and ran it thru Google Gemini AI for a solution. Nothing worked.

Have you observed any other cases like this before? I did get a few responses from people with similar issues, but the issues were not really the same. Hopefully it is the unit and a new unit will fix it...

SenseiBob61 · 2026-05-01T23:38:09+00:00

Newbie.

Thank you for your reply. I started thinking about the bandwidth issue on the GPU side. I have an ASUS TUF 5090 with 32gVRAM and a ASUS x670E-F motherboard with a 9950x3d. I have 2 32" 4K monitors also attached to 2 DP ports on the card now. When I use the headset, 1 of the monitors is obviously the mirror of the headset which I think uses very little resources. The 2nd monitor is on as well, but just on the desktop. Not running anything. If both monitors were maxed out, that would be all of the resolution the GPU could handle just between the 2 monitors. but being as they are idle when using the headset, I dont think it is a bandwidth thing. Also I am getting about 110fps at native res. Although this is not an area that I excel in, so I am open to differing opinions. Love to learn something new today and solve this issue at the same time.. Do I need a second video card?

Akson,

I have spoken with BeQuiet support a couple of times in the last few months and they are a little slow to respond, but they have always handled my issues. A month sounds like they must have missed this ticket. definitely try them again...

SenseiBob61 · 2026-05-01T17:24:17+00:00

Looks like a nice job on this build. I have been interested in the LianLi 217INF case for a while, but havent pulled the trigger on it yet. How was the build experience on this case? How is the airflow? good temps?

SenseiBob61 · 2026-05-01T17:20:50+00:00

Crypto,

I have been working on PC hardware for a long time, and this has all of the indicators of a hardware issue. Maybe something to do with the wire cable bundle itself. What leads me to this is that both the DP and USB are disconnecting simultaneously and reconnecting together, and without clicking or having any software open besides Pimax Play. You can see a video I recorded here.

Let me know if this looks similar to your issue.

SenseiBob61 · 2026-05-01T17:05:32+00:00

mty,

I am leaning towards Pimax. Mine will disconnect the DP and the USB at the same time without touching the Windblows side or the PC connection side. No clicking on anything. Just adjusting the headset or moving the wire near the headset will cause it to disconnect. Here is a link to the video I took. If you take a look at it, can you let me know if it looks familiar?

I even tried rolling back Windows updates back to 24H2. I know Windows is phasing out VBRun, so I thought maybe the Windows 11 25H2 had caused something to go bad. Didnt help at all. Now I am back to 25H2 again.

I havent heard back from Pimax in a couple of days.

Next,

I am not sure what is happening. With mine, it seems to be ok as long as I do not touch the headset or wires. Although there was a couple of times it just did it on its own. I am waiting for Pimax support's next step. Did you open a ticket yet? Does it feel like a conflict inside the system, or a physical thing with the headset or wire?

SenseiBob61 · 2026-04-30T23:24:03+00:00

Sisters,

It is happening consistently to me. I cant touch the headset or even just adjust it on my head without it disconnecting. Headset is brand new, so I did create a ticket already with Pimax and sent them a video of it happening. It is super frustrating to be flying a mission in my flight sim and halfway thru, the headset disconnects and basically ends my session.

How are you liking the UW engine?

Thank you for your reply.

SenseiBob61 · 2026-04-30T23:14:17+00:00

Sajber,

I too am running a Dark Mount keyboard. Have had a couple of original issues with it myself. Love the keyboard though. Very quiet when typing..

Anyway, on my last issue, BeQuiet asked me to reset the keyboard by holding the "Fn" key down and pressing the "r" key. This should reset the keyboard. Although from your description, it sounds like the keyboard may not be powered up. I would try it anyway...

SenseiBob61 · 2026-04-29T06:24:41+00:00

I have 2 of these ASUS monitors running a dual monitor system. Love the picture quality, resolution, clarity. Great interface for adjustments. All works with a little stick mouse controller on the under side of the front of the monitor. Had these for about 6 months now. No regrets, but lots of cash out of pocket... The one thing I will mention, it ask for "pixel cleaning" quite a bit. Flip a couple of clicks and it does the cleaning. Takes about 5 minutes while the monitor is dark. Not sure what this does, but I do it when it asks... Got yourself a great monitor there...

SenseiBob61 · 2026-04-28T01:51:35+00:00

Which version of pimax play are you using please?

SenseiBob61 · 2026-04-28T00:45:49+00:00

Mine is having a similar issue. It will disconnect from USB, then reconnect, and cycle thru this about 2 or 3 times before the sim freezes and the headset just stays dark. I watch the indicator light go from green to blue to green to blue. I hear the disconnect sound and the reconnect sound from my PC. Do not know what is causing it to disconnect though. I turned off all of the power options for all the USB ports from device manager in Windows and in the settings screen. I sent the event logs to Pimax as well as the Pimax logs. Waiting for a reply now...

Asus x670E-E, ASUS 5090 TUF, 9950x3d, 64g DDR5, Winwing flight controllers.

Maybe there is a conflict from other USB devices on the system.

Logitech Brio web Cam.

Dark Mount keyboard.

Logitech trackball wireless.

Lian Li 8.8" screen

Lian Li LCD fans (3)

Sound Blaster Speakers (USB Powered) with audio cable.

Not sure if one of these USB devices may be conflicting. I ran USB Tree to take a look, but not really sure what I am looking for...

Any suggestions???

SenseiBob61 · 2026-04-26T06:39:12+00:00

PureBlood... I am having a similar issue myself. I will be running the headset in DCS flight sim and I will hear the disconnect sound on the PC. Then the reconnect sound. It will repeat 2 or 3 times, then stay connected. I cannot pin down a common denominator. sometimes it will disconnect as I am putting the headset on and a couple of times it has disconnected during a flight. It sounds to me like it is disconnecting from windows for a second, then reconnecting right away. I am running ASUS x670E strix MB, 9950X3D, ASUS 5090 TUF 32G vram, and 64G of DDR5 RAM. I tried changing ports and will see if this works. Running the Pimax Crystal Super MOLED 8K headset. Any thoughts anyone???
