It would be cool if someone with more knowledge then me could take a look at my settings and tell me if there's room for optimations. (Pretty sure there is tongue.gif )

I went for 3.80Ghz, cooler is h80i so temps never go above 60c.
MB is P55-UD3L with latest bios version.
Cpu ratio: 20
QPI ratio: x36
(Link speed 6.84Ghz, uncore freq: 3040mhz)
BLCK freq: 190
SPD: 6.0, 8.0 would cause windows not to boot/bluescreen.
(Memory freq: 1140)
Voltage is untouched, all on optimized defaults, pretty sure thats bad but I have no idea what I should go for there.

Hmm,
Vcore is at 1.360V
Dram at: 1.536V
My Bios doesnt show me other voltages, but the default values are:
CPU Vcore: 1.1375V
VTT Volt: 1.1V
PCH Core: 1.05V
CPU PLL: 1.8V
Dram Volt: 1.5V
Dram Term: 0.75V
They are all set to AUTO, so they adjust on their own, without showing me anything. I guess I should change that...

That vCore is way high. try ur settings and bump that v core to 1.275

Alright, I've set all values to their default ones, so they wont adjust on their own. Execpt for CPu vcore, which is at 1.200V for now. Gotta do stability tests.

If 3.8Ghz is stable with only 1.2v, that would be awesome. I think 1.3'ish is the max safe voltage for a long term overclock and 72'ish a max safe temp for lynfields. You may have some decent headroom to go higher.

> Link speed 6.84Ghz

That sounds unecessarily high? If you have heat or stability troubles, maybe look into dialing that down. Cpuz shows my "QPI Link" as 2820 MHz which i'm guessing translates to 5.64GHz as a "Link speed". I've got an asus mobo with the qpi settings left on "default", bclk at 156 and cpu multi of 25.

Already did some stability tests, runs fine so far. Was suprised that it even managed to boot succesful with 1.20v.

I could set QPI ratio to x32, so link speed would be running at 6.08Ghz, cheers for the info. Gonna check it, if it gets unstable.

Heat isn't a problem here, i'm using a h80i (http://www.corsair.com/en/hydro-series-h80i-high-performance-liquid-cpu-cooler), temps wont go above 60c on full load. My pump/fans are in quiet mode so I could change that too if it gets to hot wink.gif

EDIT: The northbridge on my MB is under/between my GPU. It was kinda cold when I touched it but can get quite hot if my GPU runs at full load for some time. So went down to 6.08Ghz for now. As I sometimes end up with longer gaming sessions it might overheat due being so close to my GPU.

1.2 on their own. Execpt for CPu vcore, which is at 1.200V for now. Gotta do stability tests.

Good chip. I know i can get 4.2 but stability testing is the issue. Prime runs 5-10 C hotter than any game. But it means your rock solid. The problem is 80-85 testing for 8 hours is not a good idea. I am probably fine at 4.2GHz 1.3 volts, but because I refuse to "Test" at 80-85C i guess I'll never know if I'm stable. As long as Far Cry 4 never crashes and Valley doesnt crash I'll assume it stable. I wish there was a way to test and avoid the very unrealistically high temps.

Yupp rock solid on 1.20v. Improved the air flow in my case so even at full load it wont go above 50c, the h80i is incredible at cooling combined with this quite low volt.

Also tested 4.02ghz, run well with 1.21875v, but prefered to stay on 3.8ghz.
Does Cpu-Z show the voltage correctly? It shows 1.184v on 3.8ghz and 1.200v on 4.02ghz.

Awesome chip. HWmonitor as well. Its probably fairly accurate. You just have a really good chip. Holy smokes that cooler is over 100 dollars. Guess I wont be getting that.
