Question I have a new X10 UP motherboard and when I boot up, the system gives 4 short beep code. What does that mean? I only see 1 short beep and 5 short beep in the manual. Answer It means you are using Non-ECC memory in the system. The system only accepts ECC memory. We will add this beep code to our manual in a later revision. Was this FAQ helpful?
