I've had my system at default clock speeds since I put my machine together in March and it's been perfectly fine. Since I upgraded to 1080p and frequently fraps while playing wow, I said what the hell.

I overclocked to 4.5 and was just wondering if everything looks fine

idle
vcore = 0.96-1.008
temp = 26-29

load
vcore= max is 1.35
temp= max 48 degrees(I havent bench marked yet but this was while raiding/frapsing)

now 1.35 seems, I would think, to be on the higher side for a 4.5 oc, or am i wrong?

the settings that I changed from default to get my oc were based off a very computer savvy friend who basically has the exact system im running, here is what I changed.

8P67 settings for 4.4-4.5 GHz

AI Overclock Tuner = Manual
BCLK/PEG Frequency = 100
Turbo Ratio = By All Cores
By All Cores (Can Adjust in OS) = 44 or 45
Internal PLL Overvoltage = Enabled
Memory Frequency = DDR3-1600MHz
EPU Power Saving Mode = Disabled

Load-Line Calibration = High
VRM Frequency = Auto
Phase Control = Extreme
Duty Control = Extreme

CPU Voltage = Offset Mode = .030V

I havent messed with the vcore to set what the minimum vcore I can get while it still being stable. I made this thread just to make sure that everything is within safe operating temps/voltage!

Thanks again

Well, I see one bad thing here:
Load-Line Calibration = High
And here's why it's bad. So, I suggest you turn that off, try to keep the speed and vcore the same, and see if you're stable. Even if you have to raise the voltage a little to get stable (you shouldn't), at least you'll know what maximum voltage you're actually giving your processor.

i just built my first sb with a 2500k... everything on auto on the msi p67a-gd53 (let it push the pll if it wants) and just change the multi to 43... runs fine... stuck an old ocz vendetta 90mm hsf on it (man the stock hsf is a pos!) and it runs coooool...

twiddled a bit to get to 4.5, but had to push up all the voltages to get stable so it just didn't seem worth it for 200mhz... the ssd made way more difference than the 200mhz...

well, reading most of the hardf thread they too recommend to either have it on regular and to use offset as turning it off will drop your vcore. 1.36v max seems a little high for a small oc like mine so I might just turn llc off and use the offset to lower it until im comfortable I guess

I just read the article you linked to and I liked what they had to say about going for an "intelligent overclock". Makes a lot of sense to me. I'm no electrical engineer but I'm interpreting what I've read as meaning that if you try to get rid of vdroop by going for high load line calibration, then you are limiting your processor's ability to withstand power/voltage overshoots which could actually lead to frying the cpu in extreme cases?

With my 2600K so far I've only been using the built in easy overclock settings my Asrock Z68 board provides. You just select your overclock from a menu in 200 Mhz increments that go up to 4.8 Ghz. Obviously it's adjusting the multiplier. The problem is that when you select one of their canned options, some of the manual settings, including load line calibration) are no longer visible. I say that's a problem only because now I don't know what it's choosing for me. Hmmmm. I don't mind "auto" settings but I like to know what its doing when I select them.

My internet browser is finely online. I think its complete overkill but fast. I have it setup to run 4.5 with turbo..

have it running Virtu in imode along side a NV 560Ti . It works flawlessly . windows 7 home pre.

Cinebench I score in Cpu 7.12 An AMD 12c/12t @2.62ghz. gets 7.95

I would say thats dam good for a browser 2500K 4 cores against 12 AMD cores


Zalman 9500 As I am printsing CPU is 38c . When benching cinebench about 70c . Other benches maks stay in the 58c to 67c range.
