Bios overclock profiles is safe?

[exdhawk]

Hi,

 

i have a i7 6700k and a gigabyte gaming 3 mobo, in bios > cpu upgrade i can choose a 4.6 ghz profile for overclock, is safe to use it for gaming and everyday use?

 

thanks.

 

ps: forgive my english.

The preset overclocks probably use more core voltage than they need to, so that they are more stable on a higher percentage of CPUs. You're probably better off doing it yourself and aiming for something more more conservative than 4.6Ghz to begin with.

thanks for reply, manually i get 4.5 using 1.315 vcore, less than that windows crash in stress test (it's good?), 4.6 i dont try yet.

You want to make sure that your temps don't go above 90 in your stress tests and that you can at least do prime95 for 6 hours. Some people will tell you differently but you have to consider how long you will be putting your CPU under load and test within those limits. If you're folding 24/7 then a lower OC with a slightly higher voltage and temps that don't exceed 80 would be ideal. If you're gaming you can allow it to push into the 90s in a stress test (AVX and AVX2 are not used in games yet and the prime test in the newest version simulates something like 115% workload) because the most you'll see in a SUPER stressful gaming session will likely be around 10-20C below that. If you're encoding video with say Handbrake which uses AVX instructions you want to consider keeping your prime95 temps around 80 max as well since rendering can take a long time and you dont want to put undue stress on your cpu.

 

And keep in mind that the 100mhz overclock you're looking at with potentially an extra 0.1v will NOT gain you ANY noticeable margins in either gaming, encoding, or general use. strictly ePeen.

 

What kind of cooling are you using? And what are your load temps? Just out of curiosity.

 

And yes as MAtt100HP has said, the stock settings are a safe bet calculated from testing thousands of processors (I heard that number somewhere, maybe JayzTwoCents) and finding the lowest common denominator for voltage and temps. They also assume you have some sort of aftermarket cooler so don't go running these types of voltages on stock cooler otherwise you'll experience severe throttling and unsafe temps.

 

Good luck and happy overclocking!

thanks for the reply, I'm using a corsair h100, my temps are 21~24 in idle and 51~56 in full load in 4.5 ghz, i use intel extreme and asus realbench to stress, i go stay in 4.5 for now.
