Hello Everyone, I have this setup :
ASUS ROG STRIX Z370-G Gaming LGA 1151 Motherboard ( bios latest v0805)
Intel Core i7 8700k Coffee Lake Cpu
ZOTAC NVIDIA Geforce GTX 1080Ti AMP! Extreme Core Edition 11GB GDDR5X
Team Force Group Nighthawk RGB 16 GB 8gbx2 3200Mhz DDR4 Memory
Cooler Master MasterAir Maker 8 Cpu Cooler
I want to know the best settings for my bios . i want to use my cpu on 4.7ghz and my ram on 3200mhz.
i turned on xmp and clicked on no after it and applied intel default settings and then set the cpu ratio to sync all cores and 47 and didn't do anything else.
is this a good settings for what i want to achieve ? (4.7ghz cpu stock speed) and using balanced power mode in windows to minimize the clock speed when idle or lower loads.
my use is 2560*1440p 144hz gaming.
should i manually add a voltage or any other settings ? i checked my voltage on aida64 stress test and it goes to 1.340 with the current settings i mentioned.
Thanks !

It does not sound like it was because of the CPU voltage or the overclock, but that does not mean it was not. Whenever you adjust the voltage or clockspeed, weird things can happen. It comes with the territory. If you can run Aida 64 for 30 min, it is sounds stable enough for twitch. Could be the GPU or any other number of things.

For stability, I have found that running a bench on Cinebench R15 is a very fast way to test stability and heat. If your system can complete a Cinebench R15, it is 95% stable. Especially for gaming. So I usually don't do long stress test for my rigs. But I am also kinda lazy. lol

You can set the v-core to auto, but it will put more volts than necessary. More volts makes more heat. More heat is bad...

For the RAM, all you have to do is enable XMP.

For the CPU, you want to change your CPU frequency multiplier to 47. That will clock your CPU at 4.7ghz. 1.34 volts is high for a 4.7ghz overclock. Your vcore is either set to auto or did a "one button" OC in the bios. So change your frequency multipler to 47 and change your v-core to 1.28 volts. See if your rig will boot. If it boots then run a stress test and see if it crashes. If it crashes, up the voltage and if it is stable, then you are good or you can try and drop the voltage to 1.27 and try again until it wont boot or it crashes.

During the stress test watch your temps. I like to have my average load temps stay below 80C for daily use.

Here is a good video on overclocking.

Thanks For the help !
i used the same settings and 1.210 v-core and i ran aida 64 for 30 min and it was fine 2 hours later i was watching twitch and not under heavy load suddenly my mouse and keyboard went unresponsive (lights turned off) and my screen froze and after 10 seconds my pc restarted without any blue screen. is that for the cpu voltage ? and what happens if i set the v-core to auto ? is it bad for the cpu to run at high voltages ? thx !
