Need help. Bios bug or Something else?

I recently faced a weird a** isse in my PC. 

Suddenly I could feel that something was wrong in my PC and that it was having some issue like heating, I could smell the dusty smell when the pcb heats exhausting ffrom the back fan.

Out of curiosity I opened Aida64 sensors tab and saw that my chassis fan speeds had decreased by 300rpm. I rebooted pc and went to reset bios, to my horror I saw that my ram had its voltage auto set to 1.5v out of the blue and freq showing 3200Mhz whereas I just had XMP on at default 3000Mhz 1.35V. 

 

Also my 12V voltage in bios tab was shown as 13V. I was scared shitless and turned off the PC.


I then rebooted the PC to the bios and it took some more time than normal to boot into Bios and I saw that the voltages and ram speed were normal, even the fans had gone upto their original rpm of 1900.
I thought to myself to reset the bios and went on to flash both the main and backup to its previous version i.e I rolled back the Bios.

now I put the system on heavy stress in AIDA64 and measured PSU voltage from a spare molex with a multimeter and it read 12.04v  on the 12v side and 5.07v on the 5v side.

 

So what could the issue have been? PSU body temps near the exhaust grill was approx 42C, measured with an infrared thermometer gun.

Specs are in signature.

Well there's no point to diag while it sounds like you've already taken care of the issue by flashing the bios.

 

A more direct answer would be, sometimes, even in bios, reported readings could be wrong. Might have been something you changed and forgotten about, or least likely some sort of bios corruption. 

 

I'm interested in your thoughts on what happened.

Only thing that I changed in bios is the fan speed to full and ram to xmp. 

Maybe you are right, its not a psu issue bit still I will check ot again for a week or so to see if anything comes up. Because both Bios and Aida64 were reading the high voltage. Either the bios made a sensor go bad or rather the psu pooped out.

I found it interesting the Bios flash seemed to repair the issue. If the PSU is bad or going bad, you'll find out no matter what bios revision is installed. 

 

Thinking the XMP CL 15 latency is something the cpu memory controller might not be completely happy with. You do have the option to loosen it to CL16 instead. Then the memory might not mind doing 3200mt/s?

The memory reading in cpuz and windows task manager was 3000 at xmp cl16. But don't know why the bios bugged out like that. I also think that the sensor on the bios bugged out or rather my mobo is going bad.

Time will tell with more symptoms. 

 

I'm wondering if some automatic overclock thing got triggered either in windows from say Ryzen Master for example, or just in bios looking around. That's known to happen sometimes when there's a lot of settings and may have hit the plus key on a highlighted menu or something silly like that. 

 

Or the bios you have now installed is just better for your hardware. If it works and is working for now, don't try to fix it further.

Facing same issues again. Now checked PSu while the voltage was high and pSU voltage was okay

Maybe try a different PSU if you have one laying around or another working PC?

I am ordering a basic mobo. A320m hdv by asrock. Will test out on that mobo.

Can it run my system properly?

I don't know if the bios shipped to you will be 3000 series ready. 

Please contact the vender with this question.

Should be ok then. It does not feature cpu overclocking however. It's a super basic board.

Yes I just want my pc to run okay and atleast play apex legends lol with not going up into flames. Should have never trusted gigabyte.

I may have managed to solve the issue. I removed the aftermarket cpu cooler, it was exerting a lot of pressure I think and now I am on wraith stealth cooler. 

problem seems to have gone for now.

That is possible. Ive had no post issues from the motherboard bending too much, but that was on the table and not in a case.
