overclock i7 3770k to 4.5 ghz

[Jorgen12315]

ok, so im new to overclocking an want to overclock a i7 3770k prossesor.
I have tried on my own to overclock this chip, but i guess im doing something wrong, because i can get the cpu stable at 4.5 ghz but then i have to set vcore to auto or then i have to have 1.310 vcore set to manual. but then my cpu is getting over 90 celsius/ degrees under 10 min of stress testing with prime 95. so i need some help, what settings i have to change in my bios.
my computer speccs:
i7 3770k
GA-Z77X-UD3H
cosair rm 750w
12gb ddr3 1333mhz
kuhler h2O 620 water cooler

or it just means that 4.5 is too much for your chip, you needn't have done anything wrong.

seems bad to not even get 4.5 out of this chip

Make sure your using Prime95 version 26.6.

If you are and are still getting those temps then 4.5 is probably not achievable, try a lower clock speed.

why does that seem bad? It was the generation after sandy, which could do 4.6-4.8, BUT was soldered, ivy was the first of the non-soldered, 4.5 is a stretch from what I recall, I got my 3570k to 4.3 I could have done 4.4, but I wouldn't have expected to have hit 4.5.

My i7-3770K sits just fine at 4.9GHz 1.32v.
My i5-3570k won't go past 4.3GHz no matter what settings or voltage, but runs happily at 4.3GHz at 1.114v.

Welcome to the cpu lottery, not all cpus will OC to the same limits.

The Antec kuhlor 620 is a 120mm rad, roughly 150w capable. Your i7 is 77w TDP that's at normal average usage. Prime95 is a torture test and will run cpus at 100% which is Peak power, not TDP. With an i5, peak power is about 1.5x TDP, but an i7 with hyperthreading is around 2x TDP. So you are using a cpu that'll hit at stock levels @150w under p95. Add in any OC and expect that to go 150w+, beyond your coolers capability to stay @70°C ish.

In short, p95 will see 90's under OC on an i7 with that cooler.

where you guys recommend to start, like what voltage should i start at, to try reach 4.3 ghz?
is it any settings that i should turn on/off or is it just changing the volatge, and cock speed?

 

[Karadjgne]

Start with Google, Asus ROG forums etc. Stock Voltages on those Ivy can generally be around 1.2v-1.25v, yet with a mild OC like 4.3GHz,you'll stand a good chance of making that smaller. So just throwing numbers at the voltage is going to do nothing.
Read everything on OC of the 3770k, your motherboard, OC in general. Read questions on forums, Google anything you don't understand the meaning of and what it does.

Do all that before even opening your bios.

 

[Jorgen12315]

ok, so i finished cinebench r15 with a overclock at 4.5 ghz stable at 1.310 volts, i got 814 in score, but it's still some high volatges

 

[Karadjgne]

At 4.5GHz you shouldn't be much, if any over 1.2v. I'd suggest you look into things such as LLC, turning off any eco settings like cpu-phases etc. Can also set c-states disabled etc.

 

[Jorgen12315]

what is llc and what can i do with it? where to i find "eco settings" and stuff like that?

 

[Karadjgne]

In the bios. As I said earlier, go read! Asus ROG forums is packed with posts of ppl who OC, it's what they live for. Almost guaranteed you'll find something about your mobo, bios, capabilities. If not, the OC theory is the same, no matter what brand mobo, just the names of some settings might change.

Overclocking is a hobby, but it's one of those hobbies where it's basically essential to read up on what is what and does what.

LLC is Line-Load Calibration, it's essential for setting stability of the cpu when you start messing with vcore voltages.

Set your bios back to factory defaults (usually F5). Then reboot. Then go Read about OC. Reviews are fine, if a little lacking, but posts, posted pictures of bios settings, Googled setting names and what they do, is far more important.

If you can hit 4.5GHz being clueless about OC, you could probably hit 4.8GHz with the same temps, stability and voltages after getting a clue. But you'll only get a clue, by Reading.

Let me say it again. Slowly... Go Read!

 

[13thmonkey]

Have you researched how to OC at all? There are some very good guides out there, and questions like what is LLC is are probably in the second paragraph. Research first, do later.

The problem is how much have we forgotten to tell you, or are taking it as read that you already know? Missing something like that could kill your PC, because we forgot something in a response to a post, that's why the guides exist, so you can read, internalise, and then understand what is important. Ask qualifying questions by all means, but you need that base level of understanding first.
