Official MSI P7N Diamond (780i) Discussion/Review/Overclock/Guide/BIOS Thread

[x-built-Stan]

I'm editing this post to clarify the beep codes. When you boot there are two series of beep codes with a slight delay between them. The first is the boot beep code - see table below. The second is the number of USB devices plugged into teh motherboard directly. So if you get 1 long <pause> 2 short you have an OK POST with 2 USB devices plugged into the motherboard. Note that plugging multiple devices into a monitor or USB hub and them plugging the monitor or hub into the motherboard only counts a sone device - 1 short beep. If you are concerned or confused, unplug all USB devices and boot to get the 'true' sequence.

Overspeed,

Here are thge AMI beep codes. Note that the 1 long is a good POST.

AMI BIOS Beep Codes:

1 short DRAM refresh failure The programmable interrupt timer or programmable interrupt controller has probably failed
2 short Memory parity error A memory parity error has occurred in the first 64K of RAM. The RAM IC is probably bad
3 short Base 64K memory failure A memory failure has occurred in the first 64K of RAM. The RAM IC is probably bad
4 short System timer failure The system clock/timer IC has failed or there is a memory error in the first bank of memory
5 short Processor error The system CPU has failed
6 short Gate A20 failure The keyboard controller IC has failed, which is not allowing Gate A20 to switch the processor to protected mode. Replace the keyboard controller
7 short Virtual mode processor exception error The CPU has generated an exception error because of a fault in the CPU or motherboard circuitry
8 short Display memory read/write error The system video adapter is missing or defective
9 short ROM checksum error The contents of the system BIOS ROM does not match the expected checksum value. The BIOS ROM is probably defective and should be replaced
10 short CMOS shutdown register read/write error The shutdown for the CMOS has failed
11 short Cache error The L2 cache is faulty
1 long, 2 short Failure in video system An error was encountered in the video BIOS ROM, or a horizontal retrace failure has been encountered
1 long, 3 short Memory test failure A fault has been detected in memory above 64KB
1 long, 8 short Display test failure The video adapter is either missing or defective
2 short POST Failure One of the hardware testa have failed
1 long POST has passed all tests
