Latency problems after upgrade to version 1803
Hi,
After the upgrade last spring to version 1803 my PC began to experience latency issues. Audio popping, lagging & stuttering. I have since installed many different OS’s (Linux too) on this old Dell Studio desktop (x58 chipset, i7-950, SSD) & can verify the problem started with 1803. I am currently on 1709 & the PC is running great. I have deferred feature updates for 365 days & found the WU mini tool, much thanks to the folks who post here.
Support for version 1709 runs thru spring of 2019. Hoping I can resolve this before then.
Here’s some of Latencymon while on version 1803. USBPORT.SYS & STORPORT.SYS look like the culprits:
Code:CONCLUSION _________________________________________________________________________________________________________ Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. 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 0:41:34 (h:mm:ss) on all processors.

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: acrord32.exe Total number of hard pagefaults 13403 Hard pagefault count of hardest hit process: 2381 Number of processes hit: 59
I installed 1803 again (1809 first, just in case the latency issue had been fixed) & then installed the Intel chipset drivers: INF Update Utility - Primarily for Intel® 6, 5, 4, 3, 900 Series Chipsets. Received message stating install successful but still the latency issues persist.
Honestly have no idea what I’m doing here & hoping someone can point me in the right direction. Southbridge on X58 is ICH10R, where I’m assuming the problem resides. Did Intel/Microsoft finally drop support in 1803?
Found year old threads regarding RST ICH10R driver & BSOD on the Intel forums. No BSOD here & those posts occurred in the Creators Update, or the one I’m on now.
Way back when adding the SSD (Win7) I removed RST (or Matrix Storage Manager), seems it wasn’t necessary. Did just install them on both versions 1803 & 1809 tho, made no difference regarding latency. Don’t think those threads apply to me…
Am I not understanding the drivers at fault?
Hey, thanks for any help
