However, I only have a very limited experience with it so far. Previously, I was using the manual mode just so I could get started. However, now I'm using Offset mode so that my idle power (such as right now) is lower as well as my temps. CPU-Z is saying that my vcore at this very second is 1.008V.

So now I strongly prefer Offset Mode. Although, I don't know how to manipulate it that much at all.
When you increase Offset, you add that to the Current VID of the CPU. But the CPU will increase it's VID when you do big speed increases.

My CPU has a VID at 1.2410v for stock speed of 3.3GHz. However, when I overclock it to 4.5GHz, that VID goes up to 1.3410v Vcore. So when I add Offset + 0.020, that gives me about 1.360v + (Goes a little higher, and for the most times at 1.368v when load), which is my current Vcore for 4.5GHz.

Whoa. Now the following is no longer a mystery to me: I'm trying 4.8 GHz right now with the Offset at +0.015 and I haven't even really tested it beyond 30 minutes of Prime95 Blend because I was just doing a quick check (I mean, I'm doing a 12-hour run within the hour), but my system feels rock-solid stable. Like, you know how you can sometimes just tell by the way everything feels when you use it? Yeah, it's like that!

Although again, I'm still going to do a 12-hour run in a little bit here. I just need to get my OCN fix one last time and then go to sleep. Once I head off to sleep, I'm setting it up for a 12-hour run.

I guess now I understand why JJ feels that it's the most efficient way to overclock!


Edit: here are my current settings for 4.8 GHz that only seem stable for right now:


  • Ai Overclock Tuner: Manual
  • BLCK/PCIE Frequency: 100.0
  • Turbo Ratio: By All Cores
  • By All Cores: 48
  • Internal PLL Voltage: Enabled
  • Memory Frequency: DDR3-1866MHz
  • EPU Power Saving Mode: Disabled
  • DRAM Timing Control: 9-11-9-28-1T
  • CPU Power Management: all power-saving features and what-not are fully enabled, such as EIST and the C-states


DIGI+ VRM
  • Load-Line Calibration: Ultra High
  • VRM Frequency: Manual
  • VRM Fixed Frequency Mode: 360
  • Phase Control: Extreme
  • Duty Control: Extreme
  • CPU Current Capability: 140%
  • CPU Voltage: Offset Mode
  • Offset Mode Sign: +
  • CPU Offset Voltage: 0.015V (my full load voltage seems to like 1.368V the most, while sometimes hitting below it at 1.352V, 1.360V, and then above it at 1.376V)
  • DRAM Voltage: 1.5000
  • VCCSA Voltage: Auto
  • VCCIO Voltage: 1.15625V, but it likes to swing between 1.150V and 1.178V. However, it usually hovers most of the time at 1.162V and 1.165V while sometimes hitting 1.171V.
  • CPU PLL Voltage: Auto
  • PCH Voltage: Auto
  • CPU Spread Spectrum: Enabled

System has been up and running for about 2-3 weeks. Since day one, if the system goes to sleep the system appears to resume fine, EXCEPT the video remains dormant...(all three screens are black) The only way past the problem is to force a hard reset, and then the system resumes.
I've tried the following...
  • Via device manager Configured all devices to "wake" the system - no change
  • Installed latest drivers - (now NVIDIA 8.17.12.7533) MOBO BIOS (now 0651), et al... no change.
  • Disabled the Internal PLL overvoltage ...no change.
  • Ran CCLEANER - reinstalled the 275.33 drivers...no change.
  • How can I resolve this problem?

Try to install a older Nvidia Video driver and see if it helps.. Or... try to disable SLI

question for you guys, looking at my signature rig, is it normal for my 2600k to be running at 38-42c idle? my brother has the same setup, but with a 2500k, and his is running at 34-38c. Ambient temp is around 31-34c give or take.

edit: Should I try replacing the TIM with formula 7? (thats what my brother uses)

With that hot ambient temp, it's very normal.

so, should i leave it like that, or try changing TIM (formula 7)? I'm not interested in lapping anything.

I'd say leave it. Your idle temps are only 7-8°C warmer than your ambient. My idle temps are about 10°C warmer than my ambient right now.

Do you guys have the same case, same case fans and even the same CPU cooling? How about the overclock? How similar are your voltages and clocks?

Well, we are both on stock clocks, and he has the stock fans on his H70 (with formula 7) and his case is a CM HAF 922 (lots of airflow). My H70 has to Typhoons AP-31 (5400RPMs with a fan controller running probably at 30%) but my case's air flow is more restricted.

Well check this out:

My i5-2500K is doing it's normal power-saving stuff, so it's using 1.008V, it's at 1.6GHz, and yet my idle temps are about 10°C warmer than my ambient. It's currently about 21.5°C in my room right now. I actually think this is normal.
