New to haswell and gigabyte z97 overclocking lots of questions

Cant find a beginners guide on here that tells you about the basics of what to turn off or on or what does what on the Z97 gigabytes.

so confused by this bios haven't upgraded since 1156

#1 what the hell is performance upgrade ?
#2 what is cpu base clock and what should it be ?
#3 what is cpu upgrade ?
#4 what is cpu clock ratio (confused as there's another on another bios page which I'll get to).
#5 proc graphics clock 1100 ? is that correct if not what should that be set to ?

like below why is there another cpu ratio on another page is it the same thing as cpu clock ratio in above pic ?
what is uncore ratio ?

#5 how to set the cpu vcore to say 1.3v the voltage doesn't change on screen when you change the voltage what + would make it 1.3 vcore ?
And I presume turbo is maximum load line calibration ?

why does it say my ram is set to 1.5 volts when it's set to 1.65 by xmp ? should I be changing this value to 1.65v ?

so basically which of these settings should I use to say set a g3258 to 4.5ghz
cpu clock ratio or uncore ratio ?

Thanks for heads up I know overclocking basics I just don't know haswell.
I know socket 775 1156 etc just not sandybridge or haswell

I've set vring to 1.200 and vcore to 1.3 thus far

First thing to do before messing around is to get the latest BIOS on it.

I will try and answer some more in the morning, unless I'm beaten to it.

cheers, it came with the F5 bios guess i'll stick to that seeing as the newer 2 don't add anything other than new ssd tech
 
I can honestly say that I am in the same boat as the OP, so many functions to change. It was so easy on my other build 3770k and gigabyte board, just changed multi to x45 and upped the volts slightly and was stable as can be.

Now with this board I'm totally lost.
 
Haswell is simple once you get your head round it. It can be clocked in threes stages as a platform. First being cpu multiplier, ie 45x base clock of 100 mhz, this sorts out cpu clock speed. Ram is set separately, doesnt effect core clock. Next stage is uncore/cache clock, good for benching. Voltage for this is known as vring on gigabyte boards, cache voltage on asus boards. The other part haswell is very good for overclocking is on the memory front.
 
Think I kinda get it now you have to match the Vring ratio with the cpu ratio so both at 45x for example meaning 1:1 ratio being ideal ?
with the lowest voltages possible on vcore Vccin and Vring ? but with vring matching the cpu vcore voltage ? or ideally lowering the Vring voltage from cpu voltage ?
 
On haswell depending on your motherboard vendor, settings can be confusing. Below is for gigabyte and asus boards.

Vcore is universal on either vendor

VRIN, is cpu input voltage on gigabyte boards. On asus boards it is known as VCCIN or cpu input voltage. On asus boards you just have to tweak eventual voltage. Eventual voltage should be a mimium of 0.5v higher than cpu vcore. ie in my case, 1.300 vcore for 4.7ghz on 47 x 100 base clock = 1.800 on input voltage.

VRING, uncore or cache setting as asus call it. At default on a 4790k it is 4000mhz, this is overclocked by upping the clock and usinf VRING or cache voltage to help stabilise. In an ideal scenario, you want your cache/uncore to match the cpu multiplier, but this may need more volts. Cache clock can be grand several degrees below cpu multi, ie 47x cpu, 44x cache.
 
Off if using a proper card.

Did you want a solid overclock? i.e one that stays at whatever you set 100% of the time and doesnt throttle back and reduce Vcore when idle?
 
I'm just figuring out you cant do that on haswell and Z97 with manually set voltage (need to do adaptive voltage ?) it clocks down to 799mhz but the volts never clock down unless coretemp cpu-z reports the vcore wrong ? I do have all power saving enabled but turbo off
 
Instead of setting a Vcore for your overclock, leave Vcore on NORMAL, set offset (the option underneath) to what you want to ADD onto the stock vcore.

So if its stock 1.25Vcore at stock and the CPU needs 1.35V for say 4.5GHZ, then set offset to +0.1V

1.25+0.1 = 1.35

A bit like,

http://forums.overclockers.co.uk/showthread.php?p=27354803#post27354803

But your settings and voltage needed will be different etc.
 
Ive set +0.200 on both cpu vcore and Vring at +0.200 so both are at 1.3 volts.

seems me doing an offset of 0.85 on mine would = 1.185 volts ? hows that then ? to get to 1.3 i need to add +0.200 ?

Voltage still doesn't clock down only the multiplier and clock speed does.

Voltage remains 1.292 solid in latest cpuz and coretemp :confused:

nevermind it was delayed now the voltage is downclocking nice one
I notice in your mini guide you have cpu set to 40 but Uncore set to 45 and don't match uncore voltage to cpu voltage ? I thought they were meant to match ?

Like for 4.5 ghz at say 1.3 volts I set

45 cpu ratio
45uncore
+0.200mv offset vcore
+0.200 Vring = same 1.3 volts

Yes as you need to use the offset option for it to reduce the voltage at idle.

Setting Vcore to +.2 will "hard" set it to that value.

So put Vcore to NORMAL and apply offset of .2

.2 ? or 0.200mv ? or you saying .2 is a shortcut for 0.200 ?
this is like spinal tap when they cant find the stage door
 
.2 is the same as 0.200

its the same value, just a different way of writing it down.

P.S in my guide I have set the turboboost values to 45X each.

So when underload it Turbos upto 4.5GHz

does turboboost need to be on then ? I have mine set to disabled ? I am throttling down correctly with turbo boost off
