i7 3770k Overclock limit? - Page 4

post #31 of 43
I have yet to see a 3770K that won't run at least 4.3Ghz on stock voltage, and many will get to 4.5Ghz without any increase.

I would really suggest that you give it a try, and if voltage scares you (it shouldn't, but I understand that it is intimidating), set it to stock. Then just turn off turbo and set all cores to 4Ghz. Boot into Windows, run Prime95 for an hour with RealTemp open (only use one monitoring program at a time, ever!), and watch your highest temps after an hour. Then reboot into BIOS, up it to 4.1, and do the same Prime95 + RealTemp for an hour. Keep doingthis until yyou either can't POST or Prime95 fails or your temps exceed 90C. (Prime95 gives you temps a solid 20-30C higher than anything you will see in real world use). Once you get to where it's unstable/failed, go into the BIOS and knock the multiplier down one to your last stable clock. Then run P95 for 8, 12, or 24hrs (depending on your definition of "stable", but I have always been fine with 4hrs; not once has an overclock passed 4hr but failed 24hr for me). If it's stable after that, and the max temps aren't higher than 90C, you have a good overclock.

Also, I don't know what Thermal Paste you are using, but I highly recommend Prolimatech PK1 or PK3. You should see 4-8C lower temps than any average paste (Arctic Silver, Ceramique, etc). Switching the fan on your cooler to one with high static pressure, and using 2 fans instead of one, can net another 3-6C or maybe even more. Improving case airflow with high static pressure fans can improve temps anywhere from a couple degrees to more than 15!

Im using the cooling paste wich came with my scythe katana, so what i got to do is just change the multiplier to 4Ghz and do nothing with the volts and see if the temps are still okay? And then repeat that with 4.1 GHZ?

A Youtube video told you that you get 60+ FPS? What about your actual gaming experience? CPU overclocking will affect many aspects of your game. Take for example Starcraft 2. Because it has to create a large number of NPC's on the screen at one time, it requires a lot of computing power. At 3.9 Ghz, the game runs fine, but will begin to chug when too many units are on the screen. At 4.5 Ghz, this is erased because the processor is able to load more and load more efficiently because it's working harder and faster. Guild Wars 2 is another great example. Same thing, decent FPS throughout at 3.9, but the main cities suffer greatly. 4.5 Ghz helps exponentially.

Crysis 3 is quite dependent on GPU, sure, but a healthy OC will give an extra boost in performance. Some games more than others, but most games will see some slight benefit.

Yup, but its not so hard right to OC my CPU to 4,5?

Or am i getting lower then 60 with 3,9 GHZ in Battlefield 3 for example?

Edit: Could i use this tutorial? http://www.youtube.com/watch?v=20rCMNzkwJo or is this mostly for the people with water coolers?

Ohh no clock speed limits dictated by your cooling. Volts are all different depending on chip

Ooh ok, but if i do this tutorial; http://www.youtube.com/watch?v=20rCMNzkwJ

I dont need to change it manually right? But should it go to far because i have a normal cooler?

Start slow. 44X multi and set vcore manually to 1.25v and test for stability
