Adding 3rd CPU to ML 570 G3


OK, what is the correct order of processors when expanding this box?

I started with 2 in scoket 1 & 2 and went to add a third.

When I installed the 3rd processor & vrm in the processor 3 socket, the machine would not init and displayed an error code r1.

Thinking the new cpu was defective, I swapped new with #2 processor & vrm.

OK so far.

If I populate socket 1 3 and 4 the machine boots and runs properly.

Any ideas eventually I'd like at add a 4th

thanks

Hello Todd,

the correct sequence of populating CPUs in ML570G3 is 1, 2, 4, 3 ... the behaviour you describe is correct ...

Sounds strange, but that's how the system board is designed ...

Are you sure about this order?

When I swapped processors to fill sockets 1,2 & 4 the system shows a red led in the front and a n6 error on the display.

currently it only boots with 1 & 2 or 1,3 & 4 populated.


I don't have the 4th processor to test a 4 cpu config.

But if there is a m/b failure I need to determine this asap so I can return the systenm as defective.

Hi Todd, strange, but 1, 2, 4, 3 order is written in support documentation with exclamation at the front of the sentence ... but it may be wrong, I don't have 570G3 to test that ... Radek
