I recently overclocked my i7 3770K to 4.2Ghz, my temperature when not gaming varies from 40°C - 55°C, and when gaming it runs at 55°C - 75°C, I was just curious if these are normal / Ok temperatures, thanks.

Specs:

• Intel i7 3770k @ (OC) 4.20GHz CPU
• Cooler Master Hyper 212 Evo CPU Cooler
• NVIDIA Geforce GTX 770 GPU
• Cooler Master VS Series V750 PSU
• Gigabyte Z77X-D3H Motherboard
• Kingston HyperX 8gb RAM x2

Id stress test it for a minimum of half an hour, I know a lot of people say many hours, overnight, 24 hours. But to be honest. Unless you are handling sensitive to data loss tasks, It's not going to kill you if it crashes once or twice and you make adjustments on the fly.

I say half an hour as I was recently disheartened by one failing a stress test I thought was stable just as i was moving the mouse to close it, and it failed 17 minutes in.

If it fails, chance are you just need to increase the vcore a little, Use something like IXTU and find your voltage under stress at stock settings, then add 0.1 volts for your overclock, and if its still not stable the lazy way is to go up 0.01 volts at a time from that point till its stable, if...

The case is CM Storm Scout 2 Advanced, when I overclocked it the only things I really changed was the CPU PLL from Auto
(default 1.800V) to 1.650V, I changed the Turbo Power Limit (Watts) to 250, core current limit to 250, disabled CPU thermal Monitor, and changed the CPU Clock Ratio to 42 (default 35). Id say my average room temperature is 22°C - 25°C, and about 4 fans in my case. Just curious, by nothing dangerous do you mean nothing like its a bit high but alright, or normal for what I'm doing, thanks for the Help! by the way, I'm new to overclocking so any suggestions would be great.

Actually just a little suprised that its stable without any vcore adjustment I thought 75 was a little high for 4.2 but your board is probably just giving it a little more power than it needs.

But 75 is fine, you only need to be really concerned if its pushing 85 gaming. It starts to throttle soon after that and gets into the danger zone hitting 90+

I assume you ran some form of stress test just to make sure its completely stable?

Yeah I did 1 minute of a stress test, max temp it reached was 80°C, I havent crashed once, and Ive gamed for 1hr+ , computer has been on for about 3 hours no issues, so what do you think I should change in order to make it more stable?

Alright so I stress tested it for 30 minutes, no crashes. The max temperature it reached was 85°C (It fluctuated between 70°C - 80°C majority of the test) is there anything else you recommend I do / change?

btw when gaming I get between 55 - 70 (coretemp said it had a max of 75°C but I think that was just a random jump)

As a thought, try lowering your voltage manually, because while its perfectly safe it shouldn't really push 85c with an evo even. if you've left that to auto it will routinely draw more power than it needs to and generate extra heat.

You in a safe zone temp wise. However You shouldn't need to touch your chip stock PLL at this clocks. Instead try small voltage boost on turbo. But first did you try just changing multiplier without touching anything else? Withnthe decent chip you can get away with 4.2 at stock voltage though. Before I had my water loop in I was running safe @4.2 setting with only +0.005v offset and +0.004v on turbo boost and that was 24h Prime95 blend test stable.

When I overclocked it I just followed this video up to the 7 minute mark: https://www.youtube.com/watch?v=NxCPyF-1tTc

Not so sure about this video. Very basic and hard to understand what he up to lol
Try this http://www.overclock.net/t/1198504/complete-overclocking-guide-sandy-bridge-ivy-bridge-asrock-edition
Very good guide which actually explains why you change and what not just "you can use any voltage you want here..." Haha

Sorry, I should explain better. What I mean is that this guy on YT you watched doesn't tell you how to OC your cpu only giving some guesses on how would his chip work. Btw his cpu pretty bad if he needs 1.350v for stable 4.5GHz. You need a guide which will explain you how to oc your cpu properly. I've got mine running @4.6GHz @1.280V 24/7 stable tested. So as you can see you need to tune your cpu to it's own possibilities not follow some guy "guide" on oc different chip. Also it took me full 3 days to tune/test my cpu to find best setting. Hope that helps.

Thanks for the help, when he said 1.350v for stable 4.5GHz I think he meant a 4.8GHz overclock
