I am running Win 7 Ultimate. I recently reinstalled my OS. Using LatencyMon and DPCLatency checker, I've noticed that these three drivers are causing massive spikes. How do I replace these files with non-problematic files? (Originally, my computer was on Home Prem, I did an anytime upgrade to Ultimate, this time I did a clean install) Thanks.

Please note that the tools you used are not developed from Microsoft. We cannot be assure that the tools are compatible with Windows 7. Therefore the information you got may not be completely correct. To upgrade the drivers you mentioned, please download the latest motherboard and network adapter drivers, also upgrade the BIOS. For more information I suggest you contact the computer manufacturer support.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

I've googled this over and over. Apparently something in Windows 7 is broken with regards to networking. Disable wireless and the problem mostly goes away. My last Windows 7 machine always ran on a wire, so I never saw the issue

This is not an answer. This is a chronic problem with Windows 7. It has been reported all across the Net. I am looking for a solution not for someone to ignore the issue.

LeftisHominid is right... there is lots of talk about this problem and few answers. Many folk seem to move back to XP to avoid it. It is most common with pro-audio USB interfaces. Microsoft don't seem to be able to prioritise it. Is it any wonder that Apple has cleaned up in the pro-audio area - that is certainly where I will be going with my next purchase....sadly...

I have the same issue in Toshiba laptop, Win 7 64, and received these same files as culprits in Latency Monitor, I'm working with Focusrite 18i6 sound interface. I've tried virtually everything,windows update, updated drivers, uninstalled Anti-Virus, ran Malware Scan, Disabled: network adaptors,display drivers, ACPI battery control. Optimized power settings, optimized tcp settings..... Is there anybody running audio correctly with low latency or should we decline and accept the theory that it is a WIN 7 bug???

Dear all, I am also doing home recording with my computer, via firewire and I also see latency spikes. Its for an advanced home user difficult to judge, what is causing issues. Audio clicks and drops were mainly caused on my (high performance system) by non optimal combination of Firewire Card/Chipset, Windows 7 Firewire driver and driver of the audio Interface, but which I could finally solve. My Solution for my system: - 1st I had to buy a new firewire card with recommended chipset of audio interface vendor - Additionally I had to use the Win7 Firewire "legacy" driver -> Then my audio clicks and drops went away. Month later the vendor releases a new version of his Mixer/driver for the audio interface (Saffire mix control). And what shall I tell: - the normal Win7 firewire driver could be chosen (which seems to be more optimized in terms of latency) - under Cubase (with setting "optimize cubase for windows") the firewire latency went down from 200us to even 76-90us on average. Of course Microsoft shall work on optimizing their OS, I want an optimized OS as good base for everything. But all my problems went away in terms of recording, at least on my system, when I optimized things around Mircrosoft. With a Laptop this might be a different issue .. LatencyMon v3.0: CONCLUSION _________________________________________________________________________________________________________ Your system seems to have 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 belonging to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. You may have to disable wireless adapters to get better results.
