Prime95 Warning - Voltage

Greetings,

Brand new to the world of overclocking and have a question. I ran Prime 95 overnight and got a warning. It said "Voltage Warning 3.3! System was still running and it did not appear there was an error in the testing regime.

What did this error mean?

Thanks,
john

PS I was running an i5 2500k at 4.8 Ghz - temperatures were 77-80 degrees C.
I have a H100i liquid cooler installed. I can supply more info if needed.

More about prime95 warning voltage
  1. There is a 3,3V Rail which comes from the PSU. What is the exact power supply you have and other hardware?
  2. I have a Seagate 660w
    GTX680
    8g Corsair Vengence Ram
    ASUS P8Z77 V Pro mobo I believe
    ASUS Xonar STX Essence sound card
  3. I guess you mean Seasonic, not Seagate ;) Anyway the power supply is fine and powerful enough, but it doesn't exclude the possibility of a faulty rail. Did Prime show you the warning or an other software?
  4. Ya - Seasonic - sorry about that. Nope, no other warning. I back down the overclock a bit to 4.6 and it's running at about 70c.
  5. Well I don't think you will notice a difference between 4,6 and 4,8 GHz, but the temperature difference is quite high. You could test the rail with a multimeter to be really sure, but I don't think it's necessary. Just watch your system for a while and it should be fine.
  6. Thank you for taking the time to provide some input.
  7. OK, so I ran this all while I was at work. Came home had another error like the last one but this one was Vnode or Vmode .0348 or something like that. It appears in the lower right corner and does not appear to be part of Prime95. In fact Prime95 was happily running along with no errors.

    So I ask again, why am i getting this error?

    Well it would be helpful to know which program is causing the messages. Could it be you have the Asus AI suite running? I've read it can cause warnings because it's buggy. Also it could be too low voltage, what Vcore did you set in BIOS?

    Every PC behaves differently when it has low CPU voltage, mine worked fine, Prime went fine too, but the BIOS was freezing when I got from 4,1 to 4,2 GHz, so I had to add much more voltage. Thus a low Vcore could cause the errors, but not necessarily.

    You should play something for and look how your PC behaves and try different load tests, like Intel burn test. While it could be Primestable for many hours your PC could fail in a game.
  9. I noticed I was getting graphical artifacts in BF3. Colored digitization and black polygons. Alos noted a red monitor read on the motherboard but it said "-1 Celsius" I wonder if the motherboard could be getting to hot? It's an ASUS P8Z77- V Pro.

    I do have AI Suite and I used it to Overclock. Maybe the settings it is providing aren't right some how for my system. Perhaps i should do a manual OC.

    And thank you again for posting and trying to help. I really appreciate it. I know I will get it right at some point and learning is part of the process.
  10. Interesting - I went back and check the system. Warnings are coming from ASUS Ai2. Error message i just got - "CPU at minus 60 degrees Celsius". Ya, right. Looks like I will deleting the software and going for manual OC.

    You should always do a manual OC in Bios, it's much safer, especially at higher clock rates, the auto functions can make some bad settings. Also it's not difficult, if you haven't done OC yet, there are many manuals.

    Either you have overclocked your GPU or the auto OC raised the base clock, which is also linked with the PCI express clock, so it overclocked your GPU, too. One of the disadvantages of auto OC.

    Seems more like a bug to me. Or was it different before the OC?

    Found out problem is with AI Suite2. Last night it was telling me motherboard temp was -60 Celsius - burrrrrrr. I am going to have to do a manual overclock. Thanks for all your help.
