Overclocking - what am I doing wrong?

[Tan3l6]

Just got a new Z490 mobo yesterday  (Asus TUF GAMING Z490-PLUS ).But no luck getting it to oc. 

-0.100V  and it won't boot

+0,100V and it's an oven, look at the pic. What am i doing wrong?

So it either won't boot (not stable ) or it's 180+ watts, reported by HWiNFO64

What cooler are you using?

It can handle 190W for a few seconds. 

I watched Tech YES City video about this board, but there the overclocked to 5Ghz took only about 140W. Also they didn't show the full OC instruction.

Well, Voltage is the number one driver for power usage, and you are overclocked to 4.9 AC. This could very well be luck of the draw. You might be able to get things stable at a lower voltage by using a set voltage rather than offset. If you are using static, then you're kinda backed into a corner here, and will have to deal with the power usage. 4.9, 6C, 12T, 180 W isn't too far from reality.

(Comet Lake really isn't much different than Coffee Lake.)

Well, I got it to work at 4,8Ghz all core at about 175 watts @ small data set with OCCT.

Temps reach about 80C but that's expected.

 

Edit: untrue, still freezes.

But still one problem remains - at random time system freezes. Sound plays on a bit longer, but everything but mouse freezes.

Motherboard problem probably?

 

Or i can only run everything at default settings. Disappointing...

Not going to make another topic...

Likely just general instability, which is also the cause of the random freezing's. Sometimes a reboot solves it, if you've chosen to "shutdown" instead. Windows 10 doesn't shut down properly anymore.

I got rid of stability issues with lower LLC and higher voltage. Before I assumed LLC should be on recommended level, but is actaully not good. (recommended is level 4 of 7 but stability is with level 1 or 2)

Also, I booted to my secondary, official 10 build and all seems to be shown fine in CPU-Z and task manager.

I guess the blank CPU and RAM info in 10 insider build is just a problem with that build...

Reboot, nor BIOS defaults didn't help.
