Hello, i bought new hardware and since then i have some freezes (micro lags) and found out that the storport.sys is making it difficult for me to handle it
My Specs
MSI B550 Tomahawk
G.Skill Trident Z RGB F4-4000C18D 32GB (2x16)
Ryzen 7 5800x 8 Core
Samsung 980 NVMe M.2 1 TB PCIe
RTX 4070 Super
i alread y checked if RAID is on, but its not and i reinstalled different windows versions, but it still remains and i reinstalled all drivers and checked for updates.
Here is what LatencyMon says:
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 2:28:48 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.
Highest measured interrupt to process latency (µs): 924,30
Average measured interrupt to process latency (µs): 10,307569
Highest measured interrupt to DPC latency (µs): 917,60
Average measured interrupt to DPC latency (µs): 6,495560

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: explorer.exe
Total number of hard pagefaults 61495
Hard pagefault count of hardest hit process: 48439
Number of processes hit: 74

Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Reviewing system event logs and crash dumps can provide information on any errors or warnings related to the storport.sys driver that may be contributing to latency. Otherwise, you'll still need to contact MSI for further analysis and troubleshooting.
Okay, is there also a way to figure out why the storport.sys is making the latency so high? just wondering to know if there is any way
Then contact MSI. There probably aren't any other settings in Windows that are related to your issue. Additionally, you mentioned that you have reinstalled Windows multiple times; therefore, Windows cannot be the issue each time.
Hallo, thanks for your Feedback sadly i didnt enabled any CPU throttling and AMD Cool N Quiet is disabled, also in the Power options is high Performance enabled.
Right now i only have a Samsung M2 ssd installed on my motherboard so no SATA connections.
with friendly regards Nico Koss
Hello, Nico Koss
Welcome to Microsoft Community.
High DPC (Deferred Procedure Call) latency can indeed cause the issues you're experiencing. The storport.sys driver is related to storage port I/O, and high latency in this driver can lead to system freezes and audio glitches.
As suggested by LatencyMon, disable any CPU throttling settings in the BIOS. This includes settings like AMD Cool N Quiet and Intel Speed Step. These settings can sometimes interfere with real-time performance. Back up your important files in advance, just in case.
You can also check SATA Ports. Some users reported that moving their SSD to different SATA ports on their motherboard helped reduce latency. If you have other drives connected, try disconnecting them and see if the issue persists.
In addition, high-performance power plans can sometimes help reduce latency issues. Go to Control Panel (You can search it in Start menu) > Power Options and select a high-performance plan.
If the problem persists, consider reaching out to MSI support for further assistance:
