Extremely loud beeping on startup

I was going thru my tech teacher’s back room today and I came across a 2014 Mac Pro. I plugged it in hoping I would have found a hidden gem, but with my luck I got no dice.

As soon as I pressed the power button, there were 5 extremely loud beeps at least 1 second apart that almost made me jump. I unplugged it immediately, and tried again. 5 beeps. I tried the SMC, PRAM and NVRAM resets which all were to no avail.

TL;DR: 5 extremely loud beeps on startup each at least 1 second apart. Tried all the resets. Help!

Here’s another reference: Macintosh Beep Codes

See if you can recover the EFI and SMC firmware using these:

@danj I cannot boot up the machine is therefore I can’t try those two things you mentioned. Replacing the CPU is just simply too expensive, so I think this machine is a brick. Thanks for your helpful input!

It still might be possible!There is a special tool you can use to access the service connector on the base to recover the firmware. I'll need to find it when I go home for lunch.

@ajcooke01 - Here's the info MattCard You'll need to ask for his beta card for the Mac Pro

@danj I think I am going to just call it done. There is water damage to the Logic Board that I just discovered now that is beyond repair. I think I’ll gut it and use it as a ruler holder ;)

Gee! Such a waste ;-{ Even if you got the four core Xeon logic board it's a great system! That's what I use for photo editing.
