hi clockers, i'm new in over clock then i need some hints for making my system stable

Bert2 · Oct 8, 2016

i have
Intel i7 4790k 4Ghz Processor
Z97 Gigabyte HD3 Rev 2.1 Motherboard
Crucial Ballistix 16GB DD3 + GSkill Triden X 8GB DDR3
= 24 gb DDR3 Memory
Samsung 850 Evo 250GB SSD
Gigabyte GTX 780 3gb Windforce overclocked GPU
Corsair CX600 PowerSupply
Intel Liquid CPU cooler 120mm by Asetek

here is my stability test hope you will not scold me or get annoyed with the temps

First: why are you overclocking? What are you trying to get out of it? Is this for daily use, for speeding up heavy crunching programs, or for bragging rights?

Second: realize each CPU will have its own limitations. Just because others might be able to hit 4.6 on a 4790K doesn't mean yours can. My review unit topped out at 4.55 GHz @ 1.28V.

Third: your mboard can be a limiting factor too. Even a great CPU won't overclock as well on a mediocre board.

Hi red. Thanks for the response. I use it for rendering 2k-4k videos. And some mid heavy multitasking. I'm a bit curious in overlooking when it seems it comes with the box of my processor. my motherboard is a bit friendly because it has some features on easy tuning, fan system tuning and vtuner for graphics card. To wrap up what should be the base vcore voltage for 4.6ghz overclock?

One thing you need to understand is that a 4790K is already a factory overclocked 4770K ( same silicon, slightly better power circuits ). So, it's already using 4.0 as a base clock and 4.4 as a turbo clock. All this means you're generally not going to get a whole lot more out of it. Best you can usually expect is to get the chip to stay around or maybe a little above, its turbo frequency.

Now, I can't tell you what voltage your particular chip would need to be stable at 4.6 GHz. As I said, they're all slightly different. I think going above 1.3V puts excessive wear on the chip and don't go above 1.28V on my own 4790K. If you want to take it as high as reasonable, set the VCore at 1.28V and the multiplier at 45 and see what happens.

If you're doing this movie processing professionally, understand there's a reason professional studios don't use OC'd hardware, apart from losing warranties. OCing can lead to funny things at time, usually slight computational errors in rounding. This can mean things like glitches and artifacts in the final product.

Thanks mate. I'll try this settings. I usually do my clocking settings on my motherboard app or XTU. Should it be better on bios?

RedJaron · Oct 10, 2016

I typically do mine from the BIOS, though you can do either. Some OS apps like Intel XTU let you do dynamic programmable settings based on which application you're using, much like a programmable mouse's buttons can switch function whether you're in Excel, a web browser, or a game. This can be handy if you want to push the CPU harder in certain tasks. It's quite common for CPUs to be stable at faster clocks as long as the load isn't too heavy ( so you can be perfectly stable at 4.6 while gaming even if you can't do Prime95 AVX at that speed ). The downside is you have another process active in the background.

I don't bother doing that since I don't think it's worth pushing my CPU to an inch of its life ( my 2600K can get up to 4.8 GHz, but I leave it at 4.0 since the extra power draw, heat, and fan noise aren't worth it to me ).

Thank you but I can't do mine on bios. I should do pgup/pgdwn/+/- to configure it I can't double click or enter the cpu core and vcore voltages and if I use those + and - I just get crashes which leads me to use softwares. I am running at 4.6ghz now at 1.305v with 70sh degrees peak heat at 25 idle. Very much appreciated for the help of Internet. , :-D does my 2 different kind of ram affects the overclock?
