Supermicro H11DSI-NT motherboard behaves strangely in idle (throttling)

[aeugene1977]

Hello. The almost new H11DSI-NT behaves very strangely: when turned on first time in idle mode (Windows 11 Pro), everything seems to be fine, but after a reboot it spins up the processor coolers almost to full capacity and three memory sticks have an increased temperature, although the system is not loaded. Or another option: after the first reboot, for some reason the processor reduces the frequency to 0.4-0.5 Hz, and after the second reboot - as indicated above. The HWINFO64 program shows throttling (see screenshots). Tested with different processors and memory. I flashed the BIOS and BMC on the motherboard to the latest version, but it doesn't help. What could be the reason?

turn on in idle mode means what ? never heared about windows idle more.

Idle means that no resource-intensive applications are running, the processor load is a few percent.

S3/S4 is not supported. if you can sleep the behave can be similar like you have,

I don’t understand what this has to do with it. I have a similar board H11DSi and there are no such problems. And I also had several of the same boards, this is the first time I have encountered this behavior.

aah ok. maybe your FANs are running too low RPM ?

on the first HWinfo screenshot i see ext. PROCHOT red ( and strange language setting )
you have bad motherboard or some overheating.

Fans are OK

This is Russian language

check in BMCWebGUI(IPMI) for critical sensors

check in BMCWebGUI(IPMI) for critical sensors

IPMI shows the same values as HWINFO64.
Is any sensor damaged?
I also wanted to clarify, are all these VRM sensors located in one place on the motherboard, under one cooling radiator, which is located between the processors?

of course not. i see DIMM(B1,C1,D1) temps over 72C, maybe they engage PROCHOT thottling but not sure.
check IPMI log(s) area for critical envents.

Do you know where I can find the layout of the elements on this motherboard? I want to know where the VRM elements and their sensors are physically located. For some reason, the VRMP1EFGH and VRMP2ABCD sensors are heated significantly more than the other two.

 

[RolloZ170]

RAM tempsensor is in SPD (located on the DIMM)
check IPMI logs for critcal events.

Not RAM itself, but VRMP1EFGH and VRMP2ABCD

Not RAM itself, but VRMP1EFGH and VRMP2ABCD

but 3x RAM is 72C/75C/72C
check IPMI logs for critcal events.

but check first IPMI logs for reason of PRCHOT triggering.

Thanks for the advice, but where can I see these IPMI logs?

in the BMCWebGUI.
read manuals ?
