Asus Sabertooth 990FX R2.0 emitting a beep at post

MOBO: above (BIOS version 1503)
CPU: AMD FX8350
GPU: EVGA GTX 670 4GB 2-way SLI
Memory: 32 GB 4x8 Corsair XMS3
Case: Cooler Master HAF 932
PSU: Corsair AX1200i

I get a single beep while booting my computer. This happens every single time I boot up; it happens before I post; there are no problems that I can detect with the system. Maybe it's supposed to do this. I don't honestly know. If anybody knows the deal, help would be greatly appreciated.

    One beep post is to let you know the mb is posting fine.if the speaker not on the mb but plugged in you can unplug it or check in the bios to see if there a silence post option.
  2. This is usually an indicator that something is not present or ready. For example, a lot of CPU coolers don't spin up to full speed on a cold start and the BIOS require a minimum of 800 or 1000 rpm to be considered a minimum speed. These numbers are derived from stock coolers which typically spin very fast, where most after market cooler spin much slower. I have ASUS's AI suite installed on my M5A99x and it usually warns me that my MB is -128C and my fan is too slow, but then five seconds later it re-reads the data and the warnings go away. I wouldn't worry about. If you restart your machine after it is fully warmed up does it still beep? I couldn't find it, but somewhere there is table telling you what 1,2,3, or 4 beeps means.

    Thank you very much. It isn't a huge deal. The fans I put in are almost louder than the beep, but I always wondered about it.
  4. guys i have the same motherboard and i wanted to ask.
    Mine wont always beeps at normal boot.
    It beeps ONLY when i unplug the power.
    In normal boot there is no beep.
    Is something wrong with my hardware? cause i changed the speaker and its the same.
    Or it is the motherboards function its only beeps just once to show you thats everything ok ?

    I also removed all the hardware ( except gpu and hdd-ssd ) to see if the problem continue but with no clues same issue.
