2 - 2670's arrived this afternoon and doh!

Supermicro x9drg-qf bios 3.0 (new enough to support v2)

I was stoked. I've been running a borrowed single Cpu waiting for these.

I swapped in the first Cpu into CPU1
Woo hoo! Everything checked out in bios.

I plugged in the second Cpu.. shit, ****. No little green power light, no ipmi, no post, fan spins, fan stops.

Tried putting the 2nd Cpu int CPU1. Works like a dream... So both CPUs are good. All my RAM works in CPU1.

Tried with and without RAM on CPU2.
No nothing....

Am I missing a jumper/bios/ipmi setting or is it likely I have a dud board?

thanks as always... soon to be swapping to my 4rth board on this build.

 

[Diavuno]

every supermicro I've owned you just drop in a second chip+mem and it's good.

 

[RobertFontaine]

Yup, that's what I suspected. Now I have to return this board and shop for another. .. I hope number 4 is luckier.

This board was local and the seller has been good so the return likely won't be entirely painful but it's going to suck going through the weeks of shopping, shipping, and testing again

 

[Patrick]

Do you see any bent pins?

 

[RobertFontaine]

Pins are perfect

 

[TType85]

Stupid question, did you have the 2nd 8pin power plugged in on the board?

 

[RobertFontaine]

Not a stupid question at all. This board won't post even CPU1 without all four power connections plugged in.

So yes.. I just finished acquiring psu that has all the connectors to support this board.

That's 2-8 pins, 1 - 4 pin, and the 24 pin connecter

The behavior you describe is almost always bent pins on the CPU2 socket. I'd pull CPU2 and inspect the socket really, really carefully - with a magnifying glass at least and preferably a jewelers loupe if you can get one. Straighten any bent ones very carefully.

 

[RobertFontaine]

I have a 5x loop and a 30x hand held and I will look again with my loop but I have looked twice. The CPU2 socket looks pretty enough that it may never have been used... checking a third time now.

 

[RobertFontaine]

Pins in both sockets are perfect.

This whole used business of motherboards is a big waste of time. I feel your pain and I'm going through it myself. Personally I don't think I'd do it again. My current board is at SM repairs so hoping that it comes back in great shape.

 

[RobertFontaine]

In most case the markdown on a used motherboard is significant (not in the case of the sm x9's which are selling at almost retail). I did get an excellent price on my non-working motherboard from a local seller but I learned that you need to ask the right questions and buy from someone that has purchased off-lease equipment, has the ability to fully test, and is not motivated to sell garbage.

Lesson learned. I wouldn't give up on off lease equipment for a home lab. The price differential is so high that in many cases it is not possible to purchase equivalent hardware new. I also like the idea of not sending the equipment to the landfill. Reuse is a lot better than recycle.

Still I am feeling a bit cursed at the moment. I need hardware that I can swap on fleabay for other hardware and the next stop for this motherboard is the recycler despite it's ability to run 1 CPU. It's got no resale value.

 

[Davewolfs]

I suggest sending the board to SM to fix. The labor warranty on this board is 3 years. So highly possibly the repair will be cheap.

Turn around times 5-10 business days but you get a working board back.

 

[RobertFontaine]

I am still hoping to return this board to the person I purchased it from. This is not a new board and almost certainly not under warranty so free labour seems unlikely. Paying for an hour of a technician's time, plus shipping both ways makes little sense.
