Two beeps at post




I am new to CD Freaks and after searching the forums I haven’t found anything that seems to be my issue exactly so I’ll ask (hopefully not a duplicate thread)

Bought a new PC (parts)

MSI K9N SLI-F nForce 570LT Socket AM2+ Motherboard
AMD Athlon 64 X2 5000+ (Black)
OCZ SLI 4096MB PC6400 DDR2 800MHz (2x2048MB)
EVGA GeForce 9800 GTX 512MB PCIe

put together with existing IDE HDD and IDE DVD+/- Burner
existing 350w PSU

I got two beeps at post, after post computer gives standard
“your computer wasn’t shut down properly” then computer restarts when loading OS (it seems)

1st thought was PSU due to low wattage for new components
so I bought a new Corsair 750w PSU

hooked it up and I still get same thing
during post it’s recognizing the correct CPU and all 4 gigs test out
although I have tried testing each stick alone just in case

I’m leaning towards a bad mobo? any ideas?

thanks in advance


If you have AMI bios, two beeps suggests a memory problem.


Thanks for the reply,

The BIOS on this board is AMI

Two beeps is certain to be memory? I thought it was general hardware failure
but that’s why I’m here, I haven’t built a PC in 5 years so i’m a little rusty


Well, this is taken from the AMI bios error code page:

“2 Short Beeps Your computer has memory problems. First check video. If video is working, you’ll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM’s. Reseat them and reboot. If this doesn’t do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You’ll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard.”


Nice find, thanks!

I will check memory again, and swap in memory from another comp to test
as per your post if that doesn’t work I will call MSI for warranty support on mobo
