Predator POs-655 High Pitch Warning Sound, I Think ... I'd Like to Know Why

Greeting,

My new Predator POs-655 makes a very high pitch sound that I interpret to be a warning. It "screams" when, I believe, it is under stress. Specifically, when I run Flight Simulator 2024 in VR mode. I know that is a big draw, but I'd like to know how to prevent the sound and possible damage.

The moment I get out of a flight, the sound stops. I have heard this sound briefly a couple of other times in other situations.

Is my assumption that this is a warning correct? What can I do to prevent problems, etc?

Thank you in advance for reading this.

    Not likely a warning, though it might be the fans are running really fast when under high loads. Can you take a look at the fan speed to see what it is when the issue occurs?

    I will do that for sure next time I crank it up. You may very well be right. At this point, I think the fans are fine. Specifically, which I did not mention, is that it only happens when in Microsoft Flight Simulator 2024 in VR. And only when it seems like there is a lot of "computer work" going on, like processing for the VR flight components. I had a long phone conversation with a Predator tech and he said that this appears to be unique in their experience. But, some of the things that he said about the nature of that sound causes me to think it is a memory issue. I am going to add memory and we will see what happens. I will post news after the changes. Thanks for you comment, it is appeciated.

    What happens when you mute the speakers? If it were an issue with actual sound being generated in a bogus way that might point more toward software than hardware. The tech might have been confusing what you are hearing with the constant beep that is generated when you first try turning a system on with bad memory installed. That would be more obvious though, since the system wouldn't boot…

    Good question, billsey! In fact the sound does not come from the speakers. It is an extended beep that is, indeed, normally caused when there is bad memory on start up. I guess you could call it a "machine beep." The tech said that the extended beep would normally happen at start up and the monitor would be black, at best. In short, a failure to start.

    What is interesting is that this does not happen in Halo, Guardians of the Galaxy, Doom, Eleven Table Tennis VR or the kayak VR game I have, but can't remember the name of. It occurs during MSFS 2024 when certain things happen such as during the generation of scenery and flight configurations. My thinking is that the MSFS 2024 is so heavy on memory that the screech is a warning that all heck in the memory department is breaking loose.

    Not a very technical description, but I bet you get the idea.

    That sure sounds like it's an issue with the MSFS software itself, and not a hardware event. Though I can't image what they might be doing that causes a noise that's not coming from the speakers…

    I agree, but I will know more in a few days. I have memory on the way and we shall see what we shall see. I will report back then.

    This article at the following link is interesting because, in this case, it features an image of a little speaker that makes the beeps inside the computer -

    I recall in early computers the beep-speaker was more traditional looking, sort of what you'd see in a little transistor radio, but this tiny thing is rather, well, "different".

    That's a piezoelectric speaker and really only suitable for doing a beep. It's totally separate from the speakers the OS uses and only active during POST.
