G5 diag led 'errb' still lit after replacing HW

This is in the wrong thread, you have a Mac Pro, not a PowerMac G5

 

If the ErrB light is always on, does the same ErrB light come on after swapping the processors? I suspect that you may have tried it, but you should try that again, just as a final test.
You have already tried a different logic board.
Did you try swapping positions with the RAM riser cards?
After all that, if the ErrB light still stares at you - try a different power supply.

 

My first thoughts also, but then maybe it is something like this, after all it does say "G5"

 

But then again, why is it on a Mac website?

 

Maybe because it has a PPC CPU and this is a PPC forum, same reason there is PPC game machines discussed on this forum.
Hell, what do I know?

 

Haha but his original post says chime, so I'm guessing it's a mac

 

So maybe the original poster will step in here and put us straight, is it a PowerMac or a Mac Pro you are trouble shooting?

 

Haha I really don't mean to be rude by replying like this, but in the original post he wants us to email him. Sorry if I am sounding rude!

 

The OP mentioned "quad-cores Xeons", so that aught to have answered your question already. Probably the case similarity with the G5 and Mac Pro is what prompted them to assume what they have is an "early 2008 G5".

 

Seems strange to me.

 

Could be the memory riser card. Tried swapping them over?
