I want the palm rest too! I wonder if they will be selling one. I think I read somewhere that the keyboard is ready to accept one.

Yes!! I will now use Full control so I can have my RGB RAM turn off while sleeping!

I am waiting for this one too... With this new driver, I hope that I'll software control will be better on the CPU to have my RAM modules turn off when the computer sleeps...

Mmmm CPU remains above 4.3Ghz, no longer throttles...

Yep 3.20 fixed the issue for me!

Rainbow Channel has been added as a lighting effect for HW Playback for fans and strips. This is the default effect for LL fans that many have asked for Yeah!!

I really think 3.19 should have been pulled at this time. The issue is very difficult to troubleshoot on its own. It's not as simple as iCUE.exe taking all the CPU so it would be easy to identify. Instead it is the high system interrupts causing all sorts of issues. Moreover, if you use LatencyMon or similar tools, you will be mislead by other stuff such as video drivers or HD audio being the culprit... We had an official word from Corsair, but no details or ETA for a fix. More people might be affected, but they might not be reading the forums and still trying to figure out what is going on... At least, if the software is not pulled, there should be a statement/advisory, especially that they seem to have found the root cause at least 12 days ago... 3.18 seems to be a good version for me at least... though I'm waiting for a new version so I can get my profiles back...

That's one of the symptoms, because the CPU is constantly hogged by those interrupts.

It is most likely not the issue discussed in this thread.

You are using iCUE 3.19 right? What Corsair device do you have? Have you looked in Task Manager > Performance tab if you have constant high usage on one of your core while idle? Be sure to show all logical processors in the graph. Typically, system interrupts should normally be between 0-1% while idle.

Check for "System Interrupts" in Task Manager > Details tab. The CPU usage would be around 3-8% depending on the number of cores/thread you have. If you have 12 cores/threads like me, the usage should be hovering around 6%. Also, go under "Performance" tab in Task Manager, right click on the graph and select Change graph to > Logical processors Look for the first core and check if the usage is high 80%+

All previous versions are available to download from Corsair's website. The links are not in the download section. Just replace the version number in the URL: 3.19.120: http://downloads.corsair.com/Files/CUE/iCUESetup_3.19.120_release.msi 3.18.77: http://downloads.corsair.com/Files/CUE/iCUESetup_3.18.77_release.msi 3.17.97: http://downloads.corsair.com/Files/CUE/iCUESetup_3.17.94_release.msi

I didn’t have update KB4512941 installed and it seems to be Cortana or search processes with high CPU usage not hardware interrupts.

Latency Monitor will show you drivers that are taking a long time for execution. This is not always the driver to blame. Currently you are seeing nvidia driver causing latency, but in fact hardware interrupts are causing that latency to other drivers and since the video card is frequently used, you are seeing more latency on the nvidia driver. I had the same observation and I did a huge file transfer over my gigabit network adapter and the driver "to blame" became NDIS. Your Nvidia driver is fine. Issue goes away with iCUE 3.18. Hardware interrupts are very high priority and interrupt the CPU execution thus causing those delays and apparent lag.
