Anybody familiar enough with these boards know what he 0V6_VTT0123, 0V6_VTT4567, 1V2_VDDQ0123, and 1V8_PCP voltages represent? I’ve opened a ticket with ASRock, but I’m curious if anyone else has seen this.
I had my machine working well in the lab. When I moved it to my newly-finished server room, it won’t boot. After removing everything, it still won’t POST. The BMC boots fine, but there’s no messages on the consoles. I haven’t pulled the CPU yet, but I’ve pulled all but one stick of RAM. (The inventory shows two installed in A1 and E1, which, combined with the voltage warnings, has me worried that something got shorted during the short walk from the lab to the server room…)
‘PCP’ is the processor core, meaning that if it’s low I suspect the CPU isn’t seated properly, or is faulty.
I think VTT and VDDQ are related to DRAM.
When you installed the CPU, did you use a torque screwdriver? I’ve found it’s really necessary to use one otherwise you’re not likely to tighten the screws enough, leading to the CPU not making sufficient contact with the pads. I wonder if moving it could have jostled it loose?
When I was working with it in the lab, it sat on the floor or sideways on a shelf. After hauling it to the shop where I built a server room, when it’s racked up, it doesn’t boot.
Brought it in the house, reseated the CPU, and it came up. Racked it up in a little rack on my desk, and it has the same issue. I’ve monkeyed around with it now for a few hours, realizing that the case is probably tweaking the motherboard just enough.
I’ve bottomed out all four (five?) star screws on the mount, so it may that it’s too tight. I’ve had that be a thing before on some Mac Xeon’s after an upgrade.
Turns out there was a standoff on the case that I didn’t see that doesn’t have a matching hole on the motherboard. The manual points this out, and sure enough, I hadn’t removed it.
My machine is back in service and ready to go into production as a host for a few MikroTik CHR’s.
