Hey dudes, I need some help here. I posted in the main Intel forums, but no reply. Could just be a slow day. Anyway, I'll copy and paste my post, and maybe someone can help.

I have begun overclocking this machine, and I believe there is much more I can do to get cooler temps/higher clock. I initially left things on auto and changed my multiplier to 45, and everything went peachy. Ran Prime95 for an hour and max core temps were 87c (high mostly because of ambients, but I hear fine for stress testing). What I found odd were my voltages, they topped out around 1.4v! Now I know that's high for a moderate OC of 4.5. I tried setting my offset to -0.020 just as a starting point, and the system wouldn't post. I went back and set it to auto, but just changed the offset sign from + to -, and it still wouldn't post. I find this odd my offset won't work as a negative at all.

I tried last night to follow the overclocking guide for ASUS motherboards on here, but using those settings I got the same voltages, but MUCH higher temps. Within a minute of Prime95 I was hitting 100c and I immediately shut it down and reverted to my last known good settings. I assume the higher temps were from changing my phase control settings. I know I have adequate cooling, my case and heatsink are amongst the best for air cooling, so what gives? Any input is appreciated. Warning: Spoiler! (Click to show)

Most things in BIOS are set to auto.
Turbo ratio is set to manual @ 45
Internal PLL overvoltage is disabled
Memory is at stock 1600, but command rate is at 1
CPU PLL voltage is at 1.7000
CPU fixed frequency is at 350
CPU C1E is enabled
CPU C3 report is disabled
CPU C6 report is disabled
Package C state report is disabled
BIOS is up to date.

TL;DR:



Sorry if your temps got worse.

Let me try to help you and usually this place is slow until weekends. Anyway, try doing this, set everything to how it was set in the guide and put CPU PLL Voltage to 1.6000.
Change turbo to 42 and use offset voltage AUTO.
Boot and test prime95 when running that and I can see what's going on.

Will do, I'll be back with the results ASAP.

Okay I set the PLL to 1.6000 and everything else according to the guide, and @ 4.2 my max temps for a 12 min run of Prime95 are:

Core 1: 71c
Core 2: 76c
Core 3: 74c
Core 4: 74c

The voltage maxed out at 1.264 but stayed at 1.256 for the majority of the test. Seems high to me, what do you think?

Yea it's meant to be high right now. Your aiming for 4.5 right?

Oh okay. Yeah 4.5 or higher without going over 89c while stress testing.

some details
i7 3770k oc @4.4ghz (100*44)
mobo asus p8z77-V.


have been able to run stable @4.4ghz-1.25V fixed for some time now.
so this is the max V i want to have when under load.

first try with offset turned on
on startup 1.465V
prime 1.376V
idle 1.192V @1.6ghz

how can i get
on startup and prime 1.250V @4.4ghz
idle +-1V @1.6 ghz or what is a better alternative.

is there a fixed V i can use to make offset adjustments?

95C is fine when stress-testing. Just don't run it at 90C+ 24/7. Ok so make vcore manual 1.25 and put ratio at 45. Up the vcore until you boot up. When you can boot up, run Prime95 for 10minutes, if you can run it, drop voltage 1 notch until you fail. After that, push it back up 2 notches and try to run prime95 for 12 hours or how many you need to deem stability. If you fail, up it by 1 notch. This will allow you to get the lowest possible vcore.

What is your VID? Install CoreTemp and tell me if you don't know already.

After that will we be revisiting offset? I like the idea of my CPU throttling back when I'm just watching a movie or surfing.

Yea we will be revisiting offset definitely, just post back when you finish finding a good voltage and you are confident enough that it's stable. Remember stability is a state of mind and only you can judge if it's stable.

have installed care temp.
have now a vid of 0.9857V in no load

have made some changes at Voffset. +0.055
now at asus sensor recorder with prime running 1.228V
while on coretemp i read vid 1.2510V
on cpu-z 1.224V
