On idle it is .72v smile.gif No its not my final Oc but I thought I would take it steady in overclocking as I do not have the money to buy new parts if i stuff something up

If that is the case with the vdrop as an adaptive setting then it has to be set to auto on gigabyte boards, no adaptive mode in there bios

Just make sure to have windows run balanced power settings also or the power states will be a bit off with the vcore.

Yeah I changed that to balanced mode:)

So with those pictures I just shown, they will be safe to use as an everyday machine for gaming, bench marking and rendering?

You're completely safe. You're not even remotely close to frying your chip. Haswells seem a bit hardy IMO based on the limited info so far (due to the fact they are still new.) I whacked mine with 99C (on accident) and 1.5v+ (on purpose) and I'm still standing and it's business as usual. Not saying those are safe settings, but it takes a lot to kill a CPU as a  general rule, and if you found a way to kill one via overclocking, you're either really reckless or... well, just reckless as all the info on voltages/temps are availible online.

 

My guidelines are this, as stated in my guide:
<80C: Quit worrying, you're so cold you're on ice.

80-90C: Getting pretty warm here. This is the maximum temperature you should ever reach when you're doing your normal computing acitivties (EG, gaming, encoding, chess, whatever you do in your spare time)

90-95C: This should only be found under synthetic stress tests. Be careful.

95-100C: This is getting dangerous. I advise closing down the stress test right now. Your overclock is thermally limited if you decide to stick to your current stress test. Either delid, get better cooling, or ditch the stress test and go for an easier one.

 

Voltage: [vcore]
1.2 and under: You've got to be paranoid to worry about voltage killing anything at this point.

1.3-1.35:  Stressing on adaptive with synthetics may be dangerous. Apart from that, just watch the temps and you'll be fine. Degredation is too far too to even be worth pondering about on a lazy summer day. Heat is a larger threat here for sure.

1.35-1.45: We're starting to get serious here. If you stress with synthetics and leave the computer you could permenantly botch your chip. So, don't do anything stupid like that, eye those temps, stay frosty my friends. Everybody in this range so far are completely safe, including me.

1.5v and higher: Here I personally feel degradation may be a more prominent hazard in the long terms.

 

Please Note: Vring/CacheRatio voltage ranges are different than Vcore. If you're at say, x47 core and uncore, and you need 1.45v for x47 core, and you try to put 1.45v into Vring, you'll bust your chip. Refer to the original post of this thread. As a general rule stay under 1.3v if you're paranoid, under 1.35v if you like to stretch things a bit.

Disclaimer:

The content above is my opinion based on my experiences only.

 

 

My advice:

You have a lot of headroom to work with. Your chip can go higher. I suggest overclocking to a higher multiplier.

I already overclocked the core, its the first thing i did to test the chip.
Only when entering into 1:1 cache territory i get totally different results, where i need less vcore for the same clock. This is where cpu works the hardedst and every setting comes into play, including vccin;)

Here are some results, still working on 4.6:
Code:
4.3"3.6
VRIn: default
Vcore: 1.115
Ring: auto
Sys agent/analog/digital: auto

4.3"4.3
VRIn: 1.620 (default - 124 bsod)
Vcore: 1.090 (1.115v - 124 bsod)
Ring: 1.150
Sys agent/analog/digital: +0.10, +0, +0.10

==========================================

4.4"3.6
VRIn: default
Vcore: 1.131
Ring: auto
Sys agent/analog/digital: auto

4.4"4:4
VRIn: 1.750
Vcore: 1.116
Ring: 1.150
Sys agent/analog/digital: +0.25, 0, +0.25

===========================================

4.5"3.6
VRIn: default
Vcore: 1.140 <===== the ugly part
Ring: auto
Sys agent/analog/digital: auto


4.5"4.5
VRIn: 1.860
Vcore: 1.117  <===== the beautiful part
Ring: 1.174
Sys agent/analog/digital: +0.025, +0.010, +0.025

Look at 4.5 overclock, i can not run this overclock with the voltage and VCCIN i started with, not if i want to keep 1:1 ratio.
This mega low vcore gets stabilized by high ring and vccin.

Gigabyte boards don't have an adaptive settings. If you set a manual voltage and then enable EIST, C1E and C3 (and you may as well enable C6/7 also) it'll automatically drop the voltage at idle. So it works similarly to adaptive, except it doesn't have the huge voltage spike you sometimes see with adaptive.

Ok, I'm calling stable at 4.5Ghz. Still going to push for higher but 4.5Ghz was the minimum I wanted to get to so this will be my stable fall back settings if I can't go further due to temps.

Username: combatant3219
CPU Model: 4770k
Core Multiplier:45
Vcore: 1.225
Uncore Multiplier: 42
Uncore Voltage: 1.18
VCCin:1.82
Cooling Solution: Corsair H110
Stability Test: Prime 95 (24 Hours), IBT, AIDA64, Cinebench, Handbrake, General Use
Batch Number: L307B246
Ram Speed: 2400Mhz XMP

That's a short test. Run it for a couple of hours.

On another note, ive been messing with my permanent OC
Vcore is at 1.440V, Vcache 1.455V, VRIN at 1.9V, VCCSA at 1.460V, VCCIO at 1.210V
This is with cache at x45 and core x46 and memory 2133.

Overall did 6 hours of prime small FFT and highest temperature i had 82C but blend would freeze on me in a couple of hours or so until i upped VRIN. Overall, AVX stable.
