[SOLVED] I overclocked my cpu to 5Ghz but now i cant ..

[encise]

Hello, when i was using my MSI Z370 Mortar , i overclocked my i7-8700k to 5Ghz ( 1.350v ) , it was stable, but now when i bought my new Z390 Aorus Pro , i tried to overclock it to 5ghz but i couldn't, when i stress my cpu my pc crash with a blue screen says that " your pc ran into a problem etc .., same thing with 4.9, 4.8 with 1.350 only was stable for me, what's the reason, here is what i changed in bios:

Did you reinstall Windows after changing motherboards?

But my z370 Mortar was a normal one, and my new z390 aours designed for +5ghz , ( As they announce )

 

[WildCard999]

Increase the voltage 0.05V at a time until stable, max 1.4V vcore.

I did 5Ghz with 1.4V vcore, and still crashing with that blue screen after using Aida 64 to stress CPU .

TBH I'd go back to the MSI and return the Gigabyte.

Could it be mobos are different?

Why? i spent much money in this mobo

Well either return it or RMA the board with Gigabyte. If the BIOS is updated, temps/voltages are good and it's still not stable despite being on a "better" board I wouldn't bother keeping it. Maybe there's a hardware issue with the board and if so that's only something Gigabyte can fix.

Did you make sure you connected the 8-pin CPU connector on the motherboard?

Because the other board performed what you asked of it.

I'm not sure someone build my pc, but i guess yes he did

These must be connected to the PSU to overclock that CPU, both the 4-pin and 8-pin.

Holy crap , there is only the 8-pin connected, the 4-pins is not connected, can i connect it by my self?, and how can i get this 4-pin cable?

 

[WildCard999]

Check your PSU cables, there should be that 4-pin connection labeled for CPU or says ATX. Whoever put the system together probably doesn't have it connected to the PSU so it's probably in the box. It's pretty easy to connect so you should be able to do it yourself.

It may look like that 8-pin connection but be setup as two 4-pin connections.

Okay so now i should get a 4-pin connector from the box, and connect it from PSU to the top left 4-pin cpu connector? , i'm not sure if there is a free space in the PSU to connect more cables tbh, i mean can't i just find a 8+4 pin connectors and connect them instead of the current 8pin? or there is no 8+4 pin , i'm not sure

Your PSU should have a 4 pin connector. Just line up the connector, you'll see a clip and something for the clip to snap onto on the outside of the connector. It will only fit one way.
If you have doubts take a picture and we will tell you if it is lined up correctly.

Take a pic of the cable you think it is and post both ends to us here, this will help greatly. If there's writing on the ends be sure to show those as well.

Look at the pictures above^ , there is no 4-pin connectors, i tried to find one but i couldn't, there is only 6+2 or 8,

 

[WildCard999]

Pull off that 8-pin as it may be a 2x4-pin. If so connect that to the 4-pin and use a 6+2 for the 8-pin.

I just found a 2x4 pin connector, i connect the 8 pin in PSU and the other side wich is 4+4-pin in the mobo ( i connect the first 4 pin cable in the 4-pin connector on mobo , and left the other one ( 4-pin ) as is )
Here where i connect the 8pin in PSU:

And i tried to overclock still didn't work

That's a great question..... I realized a few weeks ago one of the two cpu plugs on my pc weren't properly plugged in.... You don't necessarily realize until you start trying to push voltage through the cpu and get failures that that was the problem the whole time.......
