Supermicro X9DRL-3F does not turn on with 2 processors

[Marcos Sachi]

Hi folks.

Me again with a question regarding Supermicro X9DRL-3F. I just bought a 2nd processor to install on my MB, but when are both installed the motherboard doesn't turn on, I see the leds on it, but nothing else. When testing each processor individually it works as a charm, doesn't matter if I use CPU1 or CPU1 on the motherboard.

The processors in question is an Intel Xeon E5-2603V2. Is there any jumper to change or any firmware update I should do before installing a 2nd processor? I thought could be my PSU, but I have one Corsair CP-9020091-UK RM650X 650 that is suppose to support this configuration.

Any advise?

Thank you in advance.

Are both CPUs the same stepping?

I believe the answer is no.

That would be my guess as to why.

Hmm..Understood.

To get both working then the Part Number should be the same? For example in my case then I'd need 2 processors with part number = SR0LB.

Thank you.

Yup match SR0LB. And the ES (Engineering Sample) chip could have any number of other issues since it is not a production chip (or it could be fine).
