  • OPUS keeps Rebooting my system

    Okay, here is the system currently:

    ASUS P4P800-MX motherboard 3.0 GHz P4 1G Ram
    60G 7200 RPM HDD
    USB Keyboard
    DLink Wireless PCI Card

    The problem. The OPUS will shut down and restart the computer every few minutes.

    What I've tried

    I changed the Pentium 4 processor out for a Celeron 2.4 ghz. That was to ensure it wasn't me pulling too much power.
    I placed a BIG Desktop FAN Pointing directly at the OPUS board with the cover off (to ensure it wasn't a heat problem).
    I've checked the ASUS Probe Application and it's showing all temps on the board are very well under their limits. Voltages? Well, 12v is about 12.5v then rest seem a tad high but they work.

    Now I am powering the OPUS with a 430W ATX Power Supply. But the LCD is not loosing power, only the OPUS so it doesn't seem like it's the ATX Power supply.

    It's still happening. It will just reboot the PC. Now when it comes back on, the computer doesn't say anything about scanning the hard drive, which is kinda odd??

    Yes, I have advanced power management enabled in the bios. hibernation is disabled for now. Power management in windows XP is set to never sleep or shut down anything (not even a screen saver or turn off the monitor). It also doesn't seem like it's a problem with APM because it's happened while I was using the computer.

    I'm not sure what's going on here. Any help would be appriciated.

    You still might be drawing too much off the 12V line. It is the most common problem with random reboots. Have a look at the users manual, I think the limit on the 12V line is 6.5A peak. I had to underclock my athlon XP1600+ so that it wouldn't reboot by itself. Do you have a 2.5" Laptop drive or usb drive you could try? The reason for this is that they only use 5V.
    Never let the truth get in the way of a good story

      Yep, too much draw. You are going to have to underclock your CPU (you shouldn't have to do it as much as Meddler did, that is low!). Do you have the 4 pin adapter going into your MB too?

        Dude, that is WAY too much power draw for the Opus

          I should have said, the drive is a laptop drive.

          I put in a celeron processor trying to lower the power requirements. There is no way to underclock my processor on the board I'm using.

          This is driving me batty, it's a damn $200 power supply!

            Okay, why the HELL does the OPUS come with a P4 connector if you can't use the thing with a P4 board!!!!!

            And yes, I checked my power requirements here:

            I'm at 120 Watts. This is really not making me happy. I think I'm gunna have to call OPUS and find out what the hell is going on!

              well I am running a P4 2.2, 256MB DDR, 120gb 3.5 HD,5.25 CDRW, PCI WiFi, OEM GPS, lilliput and a XMDirect all off of my OPUS 150 with no problems at all.

              have you had this in the car or are you only running it from inside the house?


              edit: oh yeah and my board is a ASUS P4BGL-MX which is a pretty standard mATX board

                I've got it hooked up to the 12v output of a 430W ATX Power supply.

                  I had a ton of trouble running my opus from a ATX supply, I ended up using a 20A power supply from a car radio display. It's the only thing I could get that would keep it running correctly while in the house.

                    Well, I put a meter on the 12v from he ATX supply and it's at 10.3v under load. So that looks to be the problem. Which is good cuz I didn't want to have this thing go south. I'll be picking up my Yellow Top from my car at the dealer this week, so I'll try it from there, or posibly from my other car this evening.

                    Thanks for the tip.

                        That is the fault of you MB not your Opus. You don't always need it.

                          Okay, I just bought this

                          http://cgi.ebay.com/ws/eBayISAPI.dll...tem=5775631414

                          It's got 22A continous and is adjustable. So it should more than handle the carputer needs. It's also got a built in AMP meter, so I'll know if I'm over powering.

                              I was ready to tell you that it was your ATX power supply as I read down the posts. I had the exact same problem and it drove me nuts. The voltage drop would put the Opus below the voltage it needed to see to stay running so it would shut down to "save your battery" or so it thinks. Glad you found the solution.
