Thinking About Overclocking

Go to solution Solved by typographie,

I get what you are saying Imakuni, but I am not trying to get insane numbers. Just trying to give my computer a boost.

 

Start small: 4.0–4.2 GHz should basically be a giveaway, unless you already have heat issues at stock for some reason. Such a modest overclock will probably be stable at the stock voltage, and probably won't add noticeably to heat. 500–700 MHz is fairly significant in performance terms, too. You may be happy sticking with that for awhile.

 

If you're not satisfied with that, keep going (one clock ratio, or 100 MHz, at a time) until you start seeing your stability test crash. When you do, bump the voltage up 10–50 mV (0.01–0.05 V) at a time until it stops crashing. If you find it's stable and you haven't hit 1.3 V yet, keep going until you have.

 

Edit: In reference to the post above, yeah, you may find temperatures creep up higher than you'd want at 1.3 V. But you'll probably see the temperatures get too high in advance of that, just keep an eye on it.

I know that I absolutely do not need to but i want to know what kind of numbers I could get.

 

CPU: i5-4690k 3.5GHz

 

CPU Cooler: Hyper Evo 212

 

Mother Board: MSI Z97 MATE

 

Power Supply: EVGA 500 Watt Bronze Certified

 

How many GHz could I get out of my CPU that is safe.

As many as cooling, binning, and your own daring ability allows you. Seriously, there's no "how much can I get", there's only one thing: you push it and it either fails or it doesn't, rinse and repeat with smaller / bigger numbers depending on the initial results.

 

And remember to PROPERLY stress test it.

put it to 1.3V and see how high you can get the multiplier to. Every CPU is different so what you could get for clock could vary. Crashes are to be expected, dont worry. If you think you've got a good overclock get something like AIDA64 and do a multi-hour long stress test.

Could I get link or something to help me stress test my CPU?

Asus Realbench is a decent stress testing program to help determine stability.

 

I think 4690k's generally at least get to 4.5, but many can go higher. 1.3vcore is a good limit for 24/7 overclocking, but you can definitely go higher if you want to find your max OC. It really comes down to temps. As long as you aren't pegged at 89C or above during stress testing, you'll be fine. Try to keep it around 80C under max load.

Then try to boost to whatever you feel like. I, for once, feel that the 1.3v mark people are suggesting is already an insane number (for a Hyper 212 anyway).

Depends a lot on your chip, but not a huge amount with a 212.
