Dear Support and fellow Beelink owners/ future owners. I have purchased the SER8 before xmas as there was a nice deal. Took me until January to actually start using it, but I have been doing nothing but troubleshooting since then. I cant listen to a stream or podcast without having these weird latency issues. Also the Bluetooth connection is very poor. I dont need to go far before it just falls out. I have tried everything from updating all the drivers, BIOS, also by turning off every device thats not needed (related to network/ sound etc) to try and rule out anything but so far, nothing has helped. It happens very randomly. I couldnt even use the device to play my music as it randomly glitches. I ve used LatencyMon, recommended by a friend of mine, to figure out the issue. also my network connection is not the issue I have tried to connect by LAN + WiFi but the issue remains. I dont know what to do anymore. Eventually I just gave up , thinking “it was cheap so I get what I pay for”, but in the end with the import tax, it wasnt THAT cheap. I really hope this could find a solution so I have a decent working system Thanks in advance Let me know if any more info is needed Scub

Scubsub Sorry for the trouble. Don’t worry, the PC has one-year warranty. Please send us a picture of SN on the bottom of the PC. Here are the possible solutions : ① Please go to the device manager to check if there is bluetooth driver, if no, please update the driver. After you send us the SN code, we’ll send you the corresponding driver. ② Please clear the CMOS. Please turn off the PC , unplug the power supply, and press the CMOS button (or poke the hole of CMOS with a pin) for about 10 seconds . Next, restart the PC after ten minutes. Here is the tutorial [ https://mega.nz/file/2nIRGaYI#M2aIM2bkOJshrhE8sK8MNiKopfyHlqyjnn86TypZp2w ] or [ https://url.bee-link.cn/5FdW ] ③Please right click the windows–computer management–double click Services–bluetooth–start the service. ④Please right click the windows —setting -troubleshooting —other troubleshooters— bluetooth—run , let the PC diagnose the problem and solve it automatically. ⑤Please go to the windows terminal (admin) > type in : sfc /scannow > then wait until finished. ⑥Please try this software [ https://mega.nz/file/X7hGVZwb#1tA5wEJhxH8BDtKxeB5qS2ZiIEUByAVZoOnzhSf4-Pg ]

Maybe it’s an effect of the problem I’m struggling with: https://bbs.bee-link.com/d/4095-ser8-very-high-power-consumption-idle-in-windows-desktop/11

Serli Hi Serli You might need to update the BIOS. Please send us a picture of SN number and BIOS version . So we would be able to know whether it is latest BIOS and send you files accordingly. Here`s how to check your BIOS version: Prese : Win + R , Type : msinfo32 Send us the screen. or try this https://mega.nz/#F!yuISGa4I!s1bQQajKwnsEdzjqq4nopQ

I must preface this with saying that I am not coming here with a solution unfortunately, but I’m having problems with Beelink’s website to submit something to Support myself, so I could only come here. Sorry for hijacking your post. Anyways, I am also having similar problems with audio latency with my SER8 8745HS. My intentions were to use a dedicated audio interface as I am using this computer for music production and need real time audio recording, so using Bluetooth is not really my main focus. I thought my Focusrite Scarlett solo interface was not working properly (many people said that Focusrite has compatibility issues with Windows 11), and so I just bought a MOTU M4 interface which has been lauded for its low-latency performance but unfortunately, I am still getting terrible and ultimately unusable latency readings in LatencyMon and DPC Latency Checker. I disabled and re-enabled everything in Device Manager one by one with nothing clearly being the source of the problem. I factory reset my computer multiple times, both from system and from the cloud. None of those resets fixed it. Even updated the BIOS (I believe) hoping that would do it, but unfortunately it did not. I used DDU Uninstaller to uninstall the graphics driver and reinstalled them directly from AMD and it only made the problem worse. I feel like I have exhausted almost all common solutions. Here’s the bottom of my SER8 and my BIOS. Any help is appreciated! Thanks in advance.

Logan Hi there Will other devices perform like this ? Please try some solutions here : 1.CLR CMOS First, please unplug the power supply and HDMI cable. Secondly, Please hit the “CLR CMOS” button/hole for about 10 seconds. For some models the CMOS hole could be in the Audio port . Please wait until 10 minutes later (THIS IS VERY IMPORTANT), Then plug the power supply and HDMI cable back in, turn on the PC again, once turn on the PC, you will need more than one minute to wait for the PC to enter the system. See if it works. Please try few more times. 2.Disable Fast Startup In Control Panel, click the Power Options. Select the Choose what the power buttons do. Uncheck the “Turn on fast startup.”, click save changes. 3.Please uncheck the save energy in the device manager—universal serial bus controller–USB hub—properties–power management—uncheck “Allow the computer to turn off the device to save power”

Beelink CS-Ian Chan Beelink CS-Ian Chan Hello there. Thanks for the response. Could you clarify what you mean by other devices? If you mean as in other computers, I have a Lenovo Thinkpad T490s that can handle the workload fine with the MOTU interface and it has inferior specs to the SER8. I did clear the CMOS and unchecked “Allow the computer to turn off this device to save power” on all USB hubs in Device Manager. Still having the same latency issues. I disabled my GPU entirely and that initially seemed to help, but opening my DAW makes it return to skyrocketed latency readings. Below is a full summary of my troubleshooting. BIOS Settings and Hardware Adjustments: • Disabled AMD Radeon 780M integrated GPU in Device Manager and BIOS (to reduce conflicts with DPC latency). • Updated BIOS and checked for chipset/firmware updates. • Set UMA Frame Buffer Size from 4GB to 512MB in BIOS (to reduce strain on system memory). • Disabled unnecessary system devices like High Precision Event Timer (HPET) in Device Manager. • Disabled C-states, iGPU settings, and other CPU power management features in BIOS to prevent CPU sleep states from interfering with latency. • Attempted multiple changes within AMD CBS and USB Configuration settings in BIOS. Device and Driver Configurations: • Uninstalled and reinstalled MOTU drivers. • Uninstalled and disabled Focusrite drivers (even though they were not being used anymore, remnants of these caused latency spikes). • Disabled unused devices in Device Manager, including Realtek and Bluetooth adapters, to see if they were contributing to latency. • Attempted multiple USB configurations for the MOTU interface (USB 2.↉.0, ports directly connected to motherboard). • Checked IRQ conflicts using LatencyMon and DPC Latency Checker to determine which devices might be sharing resources and causing spikes. • Checked for high interrupt handling times in LatencyMon (e.g., ntoskrnl.exe, Wdf01000.sys) and tried adjusting the system to address these. • Attempted disabling NDU (Network Diagnostic Usage) service in the Registry to alleviate network latency. Power Settings Adjustments: • Ensured that Power Plan was set to High Performance to avoid sleep or hibernation modes affecting DPC latency. • Attempted to disable USB Selective Suspend (which was unavailable in the Power Plan menu, but tried registry edits). • Adjusted processor power states and hard disk turn off settings in Power Options, including setting the hard disk turn off to Never and ensuring Minimum Processor State was set to 100%. Monitoring and Testing Latency: • Used LatencyMon to monitor real-time latency with various devices disabled/enabled. • Tried to run DPC Latency Check while minimizing other applications like Microsoft Edge, FL Studio, and other background programs. • Checked DPC Latency with MOTU interface disconnected to see if the system latency was better without the interface, finding that it was still problematic without the drivers installed. • Ran both LatencyMon and DPC Latency Check while testing various changes and configurations. • Noticed that when the AMD Radeon GPU was disabled in Device Manager, latency improved significantly (yellow baseline, with minimal red spikes), but it was still not green and was less than ideal. Results on Seperate Laptop: • When plugged into an another laptop with a lower-end CPU, the MOTU M4 interface worked with minimal latency at 44100khz with 64 buffer size (showing yellow but no audible crackling or glitches). • The Beelink system, despite having a more powerful CPU, still shows issues with DPC latency, especially when the AMD Radeon 780M is enabled. • Tried running FL Studio, where latency improved when AMD Radeon was disabled, but still failed to get consistently good performance in the green zone with the Beelink system. ⸻ Key Issues Identified: 1. Wdf01000.sys and ntoskrnl.exe were consistently reported by LatencyMon as causing significant latency spikes, particularly in idle and low-usage scenarios. 2. Disabling AMD Radeon GPU did improve latency, but it was still in the yellow zone, indicating issues with DPC latency. 3. Driver conflicts and IRQ sharing (specifically for audio coprocessors and high definition audio controllers) seemed to contribute to latency issues. 4. Power management and system optimizations (C-state settings) were adjusted to prevent CPU throttling and improve performance. I personally feel like I have exhausted all troubleshooting avenues. I purchased this less than 2 months ago and it hasn’t been the experience that I was expecting and looking forward to at all. I thought it was my 2nd gen Focusrite interface causing the issues, so I bought the 3rd gen. That didn’t solve it, so I dished out even more money for a more expensive interface. That didn’t solve the issue either. Where can I go from here? Thanks again for the response. I appreciate your willingness to help.

Clean Windows Installation Perform a fresh Windows 11 install ， here is the tutorial https://url.bee-link.cn/74zu 2.Please go to device manager and uninstall the graphic driver , then reinstall the graphic driver https://url.bee-link.cn/1M4S 3.USB Controller Analysis Use USBTreeView to check if the MOTU shares a USB root hub with high-bandwidth devices (e.g., Wi-Fi/Bluetooth). Move the MOTU to a USB 2.0 port (if available) to reduce potential conflicts. 4.Advanced Power/BIOS Tweaks In BIOS: Please change the TDP to 65W , here is the tutorial https://buildin.ai/lizong/5d983adc-ca1e-4638-972a-ce7c708c4199 In Windows: Use TimerTool to force the system timer to 1ms (reduces scheduling latency). Disable HPET via command: cmd bcdedit /deletevalue useplatformclock 5.Kernel-Level Diagnostics Use Windows Performance Analyzer (WPA) to trace DPC/ISR events: Capture a trace during audio workload. Look for drivers (e.g., amdgpio3.sys, Wi-Fi drivers) causing spikes. Check for IRQ conflicts in Device Manager under “Resources by type.”

Beelink CS-George Beelink CS-George Hello I followed the tutorial and did a clean reinstall of Windows 11 from USB drive. I did not have internet connected and disabled automatic drivers update before I connected to internet. AMD Radeon was not visible in Device Manager upon boot so I couldn’t “uninstall” it technically, but I did install it. After, I then checked LatencyMON at this point and my level of latency was surprisingly still reaching into the red zone; (Highest measured interrupt to process latency: 19011.80, and Highest reported DPC routine execution time: 20254.951753) I had not yet installed MOTU drivers or even connected the MOTU interface yet at this point because I didn’t want to introduce any variables, so I skipped step 3 and continued to step 4. I then edited the BIOS and changed TDP to 65W, but just as before Balanced was the only power plan visible in power plan settings and so High Performance was unable to be selected. Also, just as before, many settings for power plan in advanced settings are not visible. (Note: On past installations I downloaded and used the program called Power Settings Explorer to manually make some of the advanced settings visible. It succeeded in making some of those advanced settings visible and tweaking them once visible helped somewhat, but ultimately for audio recording it is still unusable. It failed to allow me to make “USB selective suspend setting” visible, which is something many trouble shooting tutorials online had mentioned.) I attempted to disable HPET through command prompt but got an error; “An error occurred while attempting to delete the specified data element. Element not found.” I went through Device Manager and disabled it there. I then installed the drivers for MOTU and the interface made ultimately no difference on the latency readings. I tried my best to follow step 5 but it’s not exactly apparent to me what needs to be done. If someone from the support team can email me or private message me to get this sorted out, that would be greatly appreciated. Thanks again for your assistance.

Logan Hello Logan, Here are some solutions: ① Please go to AMD website and download the auto-detect program.It will update some chipsets and video drivers automatically. It will identify and install appropriate drivers for their AMD hardware. The program works by scanning the user’s system to detect the installed AMD hardware components, such as graphics cards or processors. It then compares the detected hardware information with a database of AMD drivers and software versions. ②Use USBTreeView to ensure the MOTU interface is on a dedicated USB root hub. If shared with Wi-Fi/Bluetooth, disable those devices in BIOS/UEFI (if possible) or physically disconnect them. USB Power Management: Ensure all USB hubs have “Allow the computer to turn off this device to save power” disabled. Use a registry edit to enforce this globally if necessary. ③Advanced System Tweaks HPET Disablement: Force-disable HPET via Registry: Open Registry Editor (regedit). Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel. Create a DWORD DisableHPET and set it to 1. Reboot. Timer Resolution: Use tools like TimerTool to set system timer resolution to 0.5ms or 1ms for lower latency. ④Boot from a Linux live USB (e.g., Ubuntu Studio) to test audio latency. If the issue disappears, the problem is Windows/driver-specific. Tools like jackd can help measure latency. Have a nice day!

“I’m in exactly the same situation as Logan. I’m using the same model with an Apogee Boom audio interface, and I’ve spent months just trying to debug this. I followed all the instructions provided by the support team, but nothing has worked so far. Have you found a solution?”
