Questions about AIDA64 CPU usage (Asus Prime Z390-A + i7-9700K)

Recommended Posts

Hi,

I've used Aida64 for the Sensor Panel for many years. But after upgrading my PC*, I've noticed that Aida64 uses a relatively high amount of CPU (often hovering around 5%, sometimes hitting 10+%. Perhaps it always used so much but I've only noticed now.

 

Anyway, the CPU usage seems unrelated to what's actually on the sensor panel: it behaves the same whether it has 0 items on it or 100.  Though it does improve if I set transparency to 0%. And it does dip below 1% if the sensor panel is turned off completely by unchecking "show sensor panel" (as opposed to just hidden by setting all items to "hide"). It also seems to be pretty much unaffected by whether the polling rate is 100ms or 2000ms. 

 

So I have 2 questions:

 

1. Are there certain settings I can change in Aida64 that would reduce CPU usage? I only use the sensor panel and logitech g510s lcd panel (I don't even use the main aida64 window). So I'd be happy to disable anything that doesn't relate to those. Could I disable something in the stability section perhaps? 

2. Is the 5-10% cpu usage actually a problem if I don't max out my CPU to 100%?  I'm a photoshop power-user, which frequently works my CPU and RAM hard, but it usually only maxes out one or two cores (my CPU has 8 physical cores). My understanding is that, in theory at least, if Photoshop maxes out, say, cores 1 and 2, then the CPU will just shift Aida64's workload to core 3, and Photoshop's performance would remain unharmed. Is this how it works in reality?

 

Thanks

1) It would be best to first check what might cause the high CPU usage.  Try to right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> Sensor Profiling Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post. You may need to enable status bar in AIDA64 / main menu / View first.

Also right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> Embedded Controller Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post.

Generally speaking, certain Asus motherboards could operate with a very high EC (Embedded Controller) latency that would cause AIDA64 sensor module to load the CPU for several milliseconds.  You can check if your motherboard is affected by that anomaly by disabling EC support in AIDA64 / main menu / File / Preferences / Stability.  Make sure to restart AIDA64 after altering that option.  Also note that by disabling EC support you will lose a few sensor readings like CPU OPT fan RPM.

2) It's not really a huge issue, especially if you almost never max out the CPU usage across all cores.  If you only load the first 2 or 3 CPU cores using Photoshop, Windows will automatically switch AIDA64 to use one of the other cores to update the sensor readings and the SensorPanel.

Thanks for your attention, Fiery. Here's the Sensor ProfilingDump. Looks like GPU and LM78 are the main culprits?

Asus motherboards could operate with a very high EC (Embedded Controller) latency that would cause AIDA64 sensor module to load the CPU for several milliseconds.  You can check if your motherboard is affected by that anomaly by disabling EC support in AIDA64 / main menu / File / Preferences / Stability.  Make sure to restart AIDA64 after altering that option.  Also note that by disabling EC support you will lose a few sensor readings like CPU OPT fan RPM.

Yep, that seems to have done the trick! :) As soon as I disable that option (even before restarting Aida), the CPU usage goes way down. It now hovers at <1% and very occasionally peaks at ~1.5%. 

When I rerun the Sensor Profiling Dump, GPUSensorInfo is still high, but LM78 is now about 50 times lower (0.148 instead of 7.9). 

My sensor panel did have CPU Opt RPM on it, which has now stopped working as you said (it's no big deal). I can't see any other changes in the sensor panel. Can I assume that, apart from CPU Opt RPM, disabling EC support will have negligible impact for me in AIDA64? 

Also, is this high EC latency something that I should be concerned about? Is it likely to impact my general PC performance? Is it a sign of a faulty motherboard?

Apart from losing a few sensor readings, you don't lose any functionality in AIDA64 by disabling EC support.

EC latency is only a problem if you're running a software that polls EC registers.  And those are typically hardware monitoring tools like HWiNFO, HWMonitor, SIV, SpeedFan, etc.  Other kind of software would never go as deep as to talk to the EC, since they have no information to gather from the EC at all.
