Unstable SM X10SDV-12C-LNF4+

[obaltus]

Good morning,


I recently acquired an X10SDV-12C motherboard. Unfortunately, during testing, I noticed that it tended to turn it off for no obvious reason after a while of activity.
I first believed in a CPU overheating problem, so I added a fan to the existing heatsink while the CPU temperature fluctuates between 49°c and 56°c. But the problem still occurs. So I turned to the power supply which I suspected was not powerful enough or defective, but after trying different models, the problem still occurs. I also tried different types of memory, but nothing changed.
I have also tried different BIOS versions, without success.

Do you have an idea?

Thanks.

Are you using a samsung ssd by any chance?

Hello,

Thanks for your message. No, just an USB stick with memtest86+ installed.

Hi,
Best if you get a laser gun

and measure temps around your ram, chips, any of the chokers, and caps. As long as components are under 75'C it should be fine.
Next thing is to check your PSU - best to try with another one, and see if you still have this issue.

By the way what chassis are you using?
And what psu?
Do you use the 4 pin cpu or the molex connector?
Is anything else connected?

Thanks for your help, I will try measuring the temperature of the different MB components.That's a good advice. I'll keep you posted.

Right now, it is outside the chassis, on the bench. It is connected via the 4 pin cpu power hooked to a 12V 120 W PSU
There is only an USB thumb disk drive, VGA and USB keyboard connected.
