Upgraded CPUs not posting

24 posts in this topic Last Reply

Recommended Posts

Hi I was trying to upgrade my dual xeon setup with a pair of X5690s but for someone reason it does not post when both cpus are in.

 

If I take one out it posts fine, but both together and nothing. Motherboard has most up to date bios available.

 

If I put the original 2 cpus in it posts fine. 

 

I tested the X5690s individually thinking one might have been dead but this is not the case. What else should I look for?

 

I have reseated memory modules. Swapped CPUs around into opposite socket but same result.

just for check - do you have all three power cords connected to mobo?

Yep all power connected, I have removed one CPU for now and everything running but as soon as I add the 2nd one it will fail to post. Then it doesn't matter what which one I remove. If I put both E5645s back in it works. Also cleared CMOS just incase it was some BIOS issue

how you populate RAM in slots? have your tried with both CPU and just one RAM stick for each? and without any attached devices..

All dimms are in I will try take them out but the fact the 2 old cpus work baffles me

I just noticed only half my memory showing with one cpu. But with one cpu it doesn't matter what socket use will have to pull some sticks out.

This was meant to be my last 2019 upgrade!

Yes, you can use RAM with CPU only.. so, each CPU sees it's own RAM.

and i think, you should write a question to Supermicro support. in my experience they are very responsive and answer question about old tech too..

Iv reached out to Supermicro and submitted a ticket. I can't test anything until the weekend now but im hoping a simple bios fix will the fix rather than having to replace motherboard.

I might put the original cpus you back and just make sure 100% I'm not going mad.

Got a response from Supermicro who have said there's very little they can do as it's an OEM board. But if if each socket works independently it could be a power issue.

I have Supermicro 1200w redundant PSU.

Plan of action remove all but 2 sticks of ram. If still having issue then either sell the x5690 on bay and keep old cpus or buy a different supermicro LGA1366 motherboard (any recommendations?)

Have you some other PSU available, just for a test? simple standard ATX power supply wont work until it have second CPU cable or you have an adapter to switch from GPU cable.

I have pair of Supermicro 800w server PSU which I can swap the 1200w. I will give that a try today but no other spare PSU that I can use.

for just a test use a single one. 800W is plenty..
Changed the PSU, changed ram slots. Got fed up and decided I would go back to the original Xeon E5645 and same issue! It won't post with both!

As it's refurbished server from ebay I don't know if Supermicro will be able to help but now its not a case of faulty cpus

It's something preventing it from posting with processors

did you tried both cpu's with only one RAM stick with each CPU?

and remove all other connected equipment, like PCIe cards, HDDs, .. something weird is going on..

Yep I think the board must be at fault I'm waiting for a reply from Supermicro but not looking good.

As they suggested to reinstall the bios.

Just my luck it didn't work, so now Iv put the 2 E5645 back in and it's working!

Only thing I can think of is the X5690 aren't a matching pair

if model are the same, it should work..

according to your pic from BIOS - why only 20GB of RAM? one stick missing?

Good spot looks like 2 sticks not showing. I will try later.

Unraid now showing 40Gb RAM

try re seating all sticks, if that not work, then try identify faulty ones and simply not use them.

i would go for larger sticks, 8Gb stick costs about 15EUR, 16GB stick about 25EUR on ebay.

see your Mobo manual, i often see that with all RAM Stick populated they work for slower speed. 

you can go for 4x16GB sticks - 2 per cpu.
