I have completed what is only my second overclock. I have my i7-2600k to 4.5Ghz @1.28v and it has passed 8Hrs. on Prime95 with the 'max' temps at 62 - 66 - 70 - 65. Browsing through the forums i notice that some overclocks are the same ghz as mine but with higher vcores and some are clocked higher but with lower vcores than mine and using 'Per Core(cannot adjust in os)' and OFF-SET mode enabled. Is there a guide similar to the the guide that i used by Clunk, which is great for guys like me that are not yet that ecperienced with ocing, because the lower i can get my voltages (and remain stable) the lower my temps right?

Your max temperatures are quite low... so why change anything?

Yeah I don't think you'll get any lower voltage than that. The lowest I was able to get mine was at 1.3 an it turned out to be unstable when I stress tested it for longer than I initially did (now I am at 1.33 ht on). Even if you have hyperthreading off, 1.28 is really low.

Thanks for your reply guys. I hear you but i would still like to know what the benifits are of overclocking using ,Per Core (cannot adjust in os)' and off-set mode.Regards,

I don't know the argument on per core, but as for offset, I personally use it because my motherboard has vdroop issues. Using offset, the vdroop is a little less (I don't know why) on my model of motherboard. Other people use it because I think it works better if you plan on using the c1 and EIST capabilities of the CPU.

I was able to use these setting from an overclock.net forum entry on bios settings- people were posting what worked for them:I like these settings, as they give me a Vcore that occasionally goes to 1.42v during heavy loading, but then will drop to 1.000v at idle when I'm not using heavy programming. I see it as better than keeping your vcore at 1.4 volts all the time. Of course, this is my first overclocking experience, so take this advice with a grain of salt!4.8Ghz Settings - 1.000v idle - 32 degrees/ 1.344 - 1.368v Max Load - 80 degrees (Prime 2hrs Stable)AI Overclock Tuner: ManualBLCK Freq: 100.00Turbo Ratio: Enabled (All Cores)By All Cores: 48Internal PLL OverVoltage: EnabledMem Freq: (AS PER YOUR RAM)EPU Power Saving: DisabledLoad-Line Calibration: HighVRM Freq: Manual Set to 350Phase Control: ExtremeDuty Contorl: ExtremeCPU Current Capability: 100%CPU OverVoltage: Offset ModeCPU Offset: + 0.060DRAM Voltage: (AS PER YOUR RAM)VCCSA Voltage: Auto VCCIO Voltage: Auto CPU PLLVoltage: Auto PCH Voltage: AutoCPU Spread Spectrum: DisabledCPU Ratio: AutoIntel Adaptive Thermal Monitor: EnabledIntel Virtualization: DisabledIntel SpeedStep: EnabledTurbo Mode: EnabledCPU C1E, C3, C6: Enabled

What is your offset voltage?

What is your offset voltage?

I am using manual voltage (set at 1.28v) not offset mode. This is my question. If i were to use offset mode, what are the advantages and how do you overclock using this method?By the way, i have since dropped my oc to 4.4ghz. (at same vcore) dont,t ask me why but FSX seems to run that bit smoother without any loss in FPS.Regards,

I was wondering because I can't decide to run my set up between offset mode or manual voltage, when i run my voltage with a .060 offset my voltage is idling at 1.4 volts at 4.3 GHz which is too high for that frequency so i was running mine on 1.28 but at 4.1 GHz so is 1.28 on manual stable for you for an extended period of time on P95? As to the advantages of the offset mode I am not completely sure of as I am not the overclocking expert but it gives your a range of voltage above the requested Vcore so if your requested Vcore is at 1.36 volts per say then with a .040 volt offset your cpu can reach up to 1.4 volts when needed ( correct me if I'm wrong anyone, because I'm not completely sure) I don't like using this because my cpu end up idling at 1.4 volts and raises temperatures, so I was using manual mode. I don't know how you can setup your cpu to idle at 1.000v and gain as the work increases because mine idles at 1.28 volts and decreases while under stress, I know the decrease is supposed to happen but I would like to idle my cpu at a lower vcore

so is 1.28 on manual stable for you for an extended period of time on P95?

Yes. As per my original post at the start of this thread, i achieved a 4.5ghz oc @ 1.28v and it ran with no errors on Prime95 for 8hrs. with MAX temps at 62 - 66 - 70 - 65 After this as seems to be the advice of the more experienced than me, i decided to reserve judgement untill several hours on FSX with all the goodies installed. When i first started, FSX still didn't seem to be as smooth as i expected so i dropped to 4.4ghz and left it at 1.28v and for some reason that seemed to be the sweet spot for my particular rig. I have now been flying for over a week several hours a day learning the ropes on my new PMDG MD-11 with no crashes or BSODs. So i figure with that level of a/c + REX2 + UT2 + UTX + FTX-PNW i should be ok. Also on manual i dont seem to see high voltage spikes so i might just quit while i,m ahead and forget the offset mode method at least until i know a little bit more about what i am doing when it comes to overclocking.
