i had a little look at the novice guide to overclocking and i was baffled.

any one able to give me a hand? should all be here tomorrow and built asap. im guessing all these changes are done in the BIOS settings like they were of old times or are they done with an app in windows now?

whats a good place to start etc on volts and what am i aiming for with my setup?

any help greatly appreciated

Use BIOS.

Leave RAM at the default speed and voltage the motherboard sets for it, to begin with (probably be 1.5v and 1600MHz).

Set Vcore to 1.25v.

Set CPU multiplier to 44. Tick All Cores if you see that option.

Save/exit.

Do a few restarts (three for example). If all good, change multiplier to 45. Rinse and repeat, upping multiplier by one each time.

When you bluescreen, reduce multiplier by one, and begin testing with Cinebench and Asus RealBench and Intel Xtreme Tuning Utility. Also Firestrike and Unigine Valley/Heaven to test the stability of the system with GPU under load. Avoid using other stress tests/benchmarks unless you are guaranteed that they won't overvolt what you've set.

Any problems with BIOS not posting (rare if you're only increasing multiplier by one at a time) = Clear CMOS.

Use a program like HWINFO64 (works fine for me but may not work for everyone) to monitor temps and voltages. You don't want to see CPU temps higher than 75C really, for a permanent O/C. If you see them creep into the 90C range, stop immediately.

That'll give you an idea of how good a clocker it is. After that, you can mess around with more things if needed - set XMP for your RAM, try increasing voltage/multiplier on the Cache/Ring, and perhaps you're willing to go beyond 1.25v. Isn't considered safe to exceed around 1.3v without custom water cooling.

That's how I pretty much start things off. I haven't used a Gigabyte mobo in a few years though, so perhaps I'm missing a trick.

A good chip will reach 4.6-4.8GHz on 1.25v or less.
 
cheers Danny much appreciated.

potential stupid question of the day. im guessing the first thing i wanna do before i start doing what you mentioned is get windows in stalled and all up and working? or would you do 3 reboots bit first then install all the windows and drivers?

just install windows with stock , so everything on auto
 
By "do a few restarts" he means check you can boot into the operating system without crashing, so yes, you'd install Windows first and check everything is working as expected before starting.
 
Put the pictures in spoiler tags, my poor screen :p

That looks about right to be honest.

Also your RAM is 2400mhz so the XMP profile will be set to this, the faster the better.

Do a bit testing, play some games, run realbench and then if it seems stable, then up the multiplier until you get a crash then drop it down or up the vcore :)
 
Select this.

And it will bring up this. It takes time, I still don't understand it to be honest mate!

haha cheers :)

ill get some pics up in a min. i see my board has overclocked it to 4.4ghz 44 cores standard. really not sure what to do next :S

was fun trying to fit a triton watercooler in to the midi case. OC told me it would fit but dont know what planet they are on as it doesnt and it offset now hopefully it will be ok
 
here is my realbench score not sure if this is any good



here are my temps during the realbench run



that good bad ok etc room for improvement?

OK PC is up and running looked at BIOS and I'm super confused now got 4.4 out of the box

This picture shows that the 3rd and 4th core are on 4.3 and 4.2 Turbo, respectively. Which is standard for 4790K's.

You can start by changing the four Turbo ratios there to 45. Or, just change the CPU Clock Ratio on the following screen, to 45:

Up to you.

You can leave Vcore on 1.208v default if you like. But you won't get too far unless it's a gem of a chip. Well actually, if Vcore is on Auto, then it will rise automatically (up to a certain point) as you increase the clock speed.

The Asus RealBench scores are what would be expected. And the temps are very good.

Yes, it is normal to enter a value of 1.25v and the real value turns out to be 1.26v.

If you want HWINFO64 sensor icons in your notifications tray, as on the bottom-right of my desktop (the coloured squares with numbers):

Let me know. Can take more pics to explain.
