Need Help with overclocking a Intel Core i9-7940X

Hi

 

I want to overclock my Intel Core i9-7940X. But there is not a lot to be found about this cpu.

I have some Problems with bleu screens when i go above 4.2 ghz.

I think i need a better power supply but i dont know how to check it.

What are save voltages and temperature for this cpu?

 

Asus TUF X299 MARK 2 x299
Intel Core i9-7940X (With Artic Silver 5)
be quiet! Silent Loop 360mm
Corsair Vengeance LPX 16 GB DDR4 DIMM 3000 MHz/15 Zwart (2x8GB)
be quiet! Dark Power Pro 11 750W
SSD 240GB 500/550 Ultra II
250GB Samsung M.2 960 EVO
NVIDIA GTX 1050TI
NVIDIA GTX 1080TI

 

Is delidding worth the performance?

I’m pretty sure LGA2066 CPUs are soldered to the IHS. Correct me if I’m wrong. I know all of LGA2011 was

no. intel cheaped out.

 

OP: delidding will with temps. What temps are you getting?

Do you not see the amount of Delidding posts about 7980xe and such? They used shitty paste on the cpus, and people delid and put LM and got 10-25 Celsius off in temps.

750 watts should be enough power for you to OC.  What Vcore are you using?

These x299 CPUS are POWER hogs.  When overclocking they can easily draw over 300-600 watts alone, the 7980XE can draw 800+ on its own requiring its own powersupply when doing serious overclocking or a $350+ 1200-1600 watt one.

Delidding Helps with temperature issues, it would reduce the amount of heat generated, thus allowing slightly more voltage with adequate cooling.

At the moment i use stock voltages (i tried 2 follow this)

 

But i dont get to start up windows aftre some changes

Bios 42 C

In a game about 60 C

And in a Rendering (Archicad and revit ) above 90 C a

Bump the voltage up just a bit. Avoid 1.4v or higher, especially if you're new to overclocking.

The main problem that i am getting is when i try to get 4.2 Ghz on the cpu with a little extra voltage. I can get into windows but when i try to get a heavy load on the cpu i get a blue screen.

 

Also when i try to start an adobe program on my pc i get a blue screen even with stock settings. I read that this is an abobe problem. (It tries to get too much voltages to the cpu)

 

I dont know if this is a problem with the power suplly.

If you're getting 90C on all cores with a lower voltage, there's no way you're going to be able to give it more voltage with higher clocks and not have it crash.

Yeah. You shouldn’t be pushing your CPU up to those temps in the first place
