So i recently decided to OC my cpu through the intel XTU program, which works great by the looks of things, except for one thing, it does not seem to save the OC settings after computer restart. I rarely restart my pc, but I did today and noticed that my core clock went back from 4.2 down to 3.6. Another question I have is, do i need to change voltages or does the program do that itself? I tried going for 4.3 and I got the blue screen after I tried to apply it, Im guessing its because the volts were not adjusted by XTU. Any advice on how I should OC my cpu? Should I do it through my bios or XTU? Should I change my RAM speed?
Here is my setup:
i5 3570k
GTX 1070 SC 8GB
16GB DDR3 1333 corsair vengeance
250GB SSD 850 Evo
1TB WD Blue
Z77 Gigabyte MB
RMx 850 Corsair PSU

and my cpu cooler is 212 evo, temps at 4.2 never go above 65C

Also speccy for some reason shows that I have only 667 Mhz speed for my RAM, any ideas why?

Any help would be appreciated.

It all depends on system stability. No overclock is an exact science. Your voltage seems low, does it stay at that under load? For checking if adaptive mode is on there'll be a setting in your BIOS.

And yes definitely stress test. For taht, iXTU can be used, but Prime95 or Unigine are better imo. Stress it for a good few hours to make sure it really is stable.

Your RAM voltage is fine.

Only disable turbo if you encounter instability or crashes. Again, depends what you can get stable with really. Overheating will be your biggest enemy

Never use software to overclock your CPU, always do it in your BIOS. You may need to raise voltage depending on the circumstances. Increasing voltage (to a safe level) can help with system stability.

The reason it resets on reboot is all software OC's are wiped when you reboot, as a safety feature, and you need to save/load the profile each time. iXTU is notoriously unreliable and I wouldn't use that..

RAM in Speccy only display half of the actual RAM, as it's Double Data Rate (DDR) so you have 1333MHz.

Ok, so should i tink with voltages if I am to make it to 4.2 through bios? I also just restarted my pc and the clock speed seems to be at 4.2 for now. Also what are safe voltage levels?

And should I mess with ram speeds at all?

Only raise the voltage if your system becomes unstable. What is it set to? Is it on adaptive mode? Anything up to 1.5v can be considered safeish.

Overclocking RAM along with CPU will put more pressure on the system and make it work harder, so only if its stable. There is no need to though.

Current vcore voltage is at 1.104V and Dram is at 1.512V
Not sure how to check if its on adaptive mode

Also if I do change the core clock to 4.2 from 3.6 should i run any kind of stress tests? If so any particular ones?

Should i also disable turbo mode?

Yes adaptive is on, voltage gets to about 1.250 under full load, temps still don't go above 65C even at full load @ 4.2. So far so good, will run a stress test overnight then, thanks.
