BIOS reset when active XMP

[Zach_01]

I used SOC VOLTAGE = 1.100

Then I suggest that you either raise SoC voltage to 1.15V or reduce cLDO VDDP to 1.050V

Did you confirm the actual values with any software?
RyzenMaster show these and HWiNFO (main page)

oh boy you educated yourself about this topic !
i did not help ya-you helped yourself with a little push in the right direction.

your are the men !

I put the SOC voltage 1.15.
Do I want to reduce the dram voltage to 1.35v.

if its stable then yes-your motherborad seems to overvolt quite a bit

The only problem I have today is when I turn off the PC, most of the time it takes a long time to shut down, between 1 and 2 minutes.
Does this have anything to do with memory frequencies and timings?

 

[basco]

normally not-do ya have some usb sticks or other connected?

ya could try to disconnect everything ya dont need and test

Did you try to lower the cLDO VDDP to 1050mV and keep SoC to 1.100V?
Same on the DRAM voltage. Less voltage is always better for any chip/component as long as it is working in stability. "Try and error" is the only way to determine voltage levels.

As for the long shut down time...
Did only do this after you increase SoC voltage to 1.15V? If yes, then you know the drill.
It also could be some software doing this.

Whats you memory factory specs, and what settings are you running them now? (speed, voltage, primary timings and CR)

And I have constantly attached on a back usb port a flash drive that contains Win10 installation files, some board BIOS profiles, some BIOS (bin/rom) files, and some pictures from BIOS captured screens.
It does not slowing down shut down or boot.

I breadboard the system first.

Then change the battery and clear cmos, then i try different ram, after that if it doesnt change I send board back for new one.

I go lower the cLDO VDDP to 1050mV and keep SoC to 1.100V.

No, It takes time to shut down with soc voltage 1.1.

I have nothing connected

 

[maxfly]

you most likely need to tweak your voltage or timings to get rid of the slow shut down. how did it do with the increased memory voltage before? once youve settled on a solid oc make sure you test with memtest86 etc... its not uncommon to have an oc seem stable until you stress the system.

Hey @Master_Cyber !

I am having exactly the same issue with the same MB (B540M Steel Legend), however different CPU and memory. I am using a Ryzen 7 3800X and 2x8gb Corsair RBG PRO 3600mhz with XMP enabled (18-22-22-42 @ 1.35v).

Pretty much same deal, I activate XMP and use it for mainly gaming for around 3-4 days, then BIOS just resets randomly...

Have you solved this completely? Any additional tips here from anyone?

Thanks!

I put all this information manually.
I used the DRAM Calculator.

I think the big secret is CAD_BUS, DATA_BUS and SOC_Voltage.

Solved my problem, since February I no longer have the bios reset.
