Hello guys,

i did some overclocking last night with my 7940x on a Strix x299 gaming e

this was my OC settings:
- adaptive volt 1.229v with negativ offset: -0.32v
- loadline call lvl 2
- OC by each core
- 2 cores: 4,6ghz
-12 cores: 4,5ghz
- all the volts in the "each core menu on auto"

ran prime 95, after 6 min the pc turned off (no bluescreen)
i did not see any cores over 85c

now the pc turns on for 2 sec and back off, HELP plz

(power cord has been out for 10hours, no change)

MB has no reset bios button on the back

is it the little round silver thingy right? (have to take gpus out and shit .. damn)

that puts bios back to default?

 

.. im like.. 1.229v with minus 30 cant kill a cpu... 

maybe my mistake was leaving the core volt auto iin the by specific core meny...?? even i had put the adaptiv ting to 1.229 in the other meny??

 

could that have fried it? killed it...?

easier to find the clear CMOS pins and short them. you wouldn't have to take out the gpu and battery for that.

Remove the motherboard CMOS battery for 15 mins and then re-insert it.

15 minutes is a bit too much, aint it? it usually is enough to plug out the psu cable, press the power button to make sure there is no rest elctricity in the system, take out the battery, wait around a minute and plug everything back in. I dont see any advantage and disadvantage in waiting 15 minutes rather than 1, except that you are wasting time

No, some boards require that much time for it to clear fully.
Do that and provided you didn't kill anything it should start working again at least.

 

Also make sure you power off or unplug the PSU from the wall, if it's still getting power it won't clear.

Unplug or switch off the PSU first, then remove the battery and leave it out for the suggested time.
Reinstall the battery first, then plug it back up to the wall or switch it back on in that order and start the system.

That's because those aren't the pins you short.
Those should be right next to the battery in most cases with a "CMOS" label. There should be three pins total at that spot all in a row, no more. However if you remove the battery shorting pins isn't required since all you're doing is disconnecting the battery anyway via a jumper when you short the pins.

Just remove the battery as I had indicated above and it should either clear or show itself having a real problem.

I'm glad you got it working again - That's what counts.
