Hello everyone! Id like to start of saying that this is my first time ever trying to overclock and im sorry if there is some obvious stuff that i am missing.

This is my setup:

Intel i7 2700k
Gigabyte GTX 1070 G1 Gaming
16gb DDR3 1333
Corsair TX650
Cooler Master V8 CPU cooler.
500gb Samsung Evo SSD

So i have wanted to overclock for a while now, and i have read some guides so i decided to jump right in. I haven't changed much in my bios, i have just changed the CPU multiplier from 35 to 44. After some reading i tried to run it at 1.25v. After 10 minutes in Prime95 it bluescreened. So i went to 1.30v. Ran Prime95 for 30 minutes and all good. Also ran some benchmark programs (heaven and valley) and it was all good. Also i played Witcher 3 for about 1 hour and everything was good. In Prime 95 at 100% load the temp is about 70C.

So i have some questions about this.

- Is this okey to run in the long run? I am not looking to go super far with my overclock. Just wanted to give my CPU a boost. I am happy with the performance as it sits now.
- I have seen that people recommend running Prime95 for several hours (understandble), but for 24hours? Why? In what scenaro would your CPU be at 100% for that long?

When i play games the CPU sits at about 30-50 percent. Yes, i this setup is for gaming, not much editing or anything else.

Do i need to do any changes or am i good to go here?

Thanks for your help!

The 24 hour test is more of a "peace of mind" deal from what I gathered. Most people usually deem an overclock perfectly stable if it runs OTTC/Prime95 for 4 hours without errors/crashes. My suggestion would be to run Prime95 for four hours, and another stress testing app after that, such as OTTC or Aida64 for another 3-4 hours.

24hrs used to be the standard...sometimes I adhered to it (occasionally, I just ran it for 12hrs) and sometimes, I didn't but that was one of the qualifiers for a stable OC 10yrs ago.

I need to check out what my settings are but I have a 2600k sitting in my other machine that is running at 4.8ghz with a pretty hefty - modifier on offset mode. The 2700k seems to have been binned a little better So i would expect you could easily hit 4.5-4.7ghz on that one.

Actually I was shocked at how much better the temps on my 2600k are at 4.8ghz than my 7700k at stock. My 2600k is back on air cooling with a hyper212 and still hits 62-66c on p95 at 4.8ghz.

Makes me pretty disappointed at intel for no longer soldering on the IHS. Maybe Ryzen launch will force them back into a proper solution for their Die-IHS approach.

Some times Prime95 fails at 10-15 hours. Once I have my finale adjustment and test I let Prime95 run 24 hours.
