Any Pros That Can Help Me Get Stable? i7 2600K OC

post #1 of 8
Thread Starter 
Hey guys,

I am trying really hard to get a stable overclock on my system but have had no luck so far. I am not overly experience but I have a decent amount of knowledge into overclocking just not advanced settings.

Bios Settings:

Bios Settings

Main-

BIOS Version - 1502 x64
Build Date - 03/02/2011
EC Version - MBECE - 0018
ME Version - 7.0.4.1197
South Bridge Stepping - B3 Stepping

CPU Information-

Intel Core i7 2600k p 3.4GHZ
Speed - 3432

Memory Information

Total Memory - 8192
Speed - 1600

AI Tweaker-

Target CPU Turbo Mode Speed: 4600MHZ
Target DRAM Speed: 1600MHZ

AI Overclock Tuner - Manual
BCLK/PEG Frequency - 100
Turbo Ratio - BY ALL CORES
By Call Cores - 44
Internal PLL Overvoltage - Enabled
Memory Frequency - DDR3-1600
EPU Power Saving Mode - Disabled

DRAM Timing Control -

Primary Timings: 7 - 8 - 7 - 24 - 2T

CPU Power Management-

CPU Ratio - AUTO
Enchanced Intel Speedstep Technology: Enabled
Turbo Mode: Enabled

Digi+VRM-

Load Line Calibration: Auto
VRM Frequency: Auto
Phase Control: Extreme
Duty Control: Extreme
CPU Current Capability: 100%

CPU Voltage- Manual Mode

CPU Manual Voltage - 1.35V
Dram Voltage - 1.6V

Advanced-

CPU Configuration-

CPU Ratio - Auto
Intel Adaptive Thermal Monitor - Enabled
Hyper Threading - Enabled
Active Processor Cores - All
Limit CPUID Maximum - Disabled
Execute Disable Bit - Enabled
Intel Virtualization Technology - Disabled
Enchanced Intel Speedstep Technology - Enabled
Turbo Mode- Enabled

What I Have Tried:

I started with the above Digi+VRM settings and started with a voltage of 1.28V. I posted but BSOD within 20 seconds of Linx/IBT.

I have been slowly increasing the voltage bit by bit and I am now up to 1.35V and I just BSOD a minute ago.

I really don't want to back my OC off too much as I feel that I should be able to hit 4.6GHZ easily. However, maybe my chip just cant sustain that frequency.

My temps are around 74.6Degrees average at load on Linx.

My main concerns are the advanced Digi+VRM settings and mostly Load Line Calibration. Under load in CPU-Z I am getting roughly 1.336V when running benchmarks.

Any other settings that seem out of wack let me know. I would really appreciate some help getting this stable!

BSOD Error code is 124 which afaik is Vcore.

Your settings look fine. You might want to change VRM Frequency: Auto to 300 or 350, but I leave mine on auto for 4.7. Also, Internal PLL Overvoltage probably doesn't need to enabled for 4.6, but I don't think it will make a difference.

Need some help with where to go!

Seems like you have some vdroop. Set your VDroop settings so you have the least VDroop, and aim for 1.38 under load, that's what my CPU takes at 4.6GHz.

Just keep upping voltage. Not all can do 4.6 @ 1.35. I need 1.385 for 4.7.

Question:

I BSOD at this voltage running LINX but I am having the same problem as before. When I am browsing or just doing every day tasks my computer freezes.

I am trying to diagnose WHY it is freezing so here are some details of what happens...

a) I hear an almost faint power down noise inside the case when it happens

b) If I am browsing the internet for example I can still move my mouse but all pages freeze and everything becomes unclickable. I usually cant Cntrl Alt Delete as it does nothing until the freeze ends but if I am able to press Cntrl Alt Delete it just says on a blue screen "preparing security options"

c) Freeze generally lasts 30-70 seconds then goes back to normal. No other issues other than the freeze...

Can this noise and everything else be caused by an undervolted overclock?

Do I continue to upvolt?

Either lower the frequency or increase the vcore bro.

Why dont you make sure 4.5 is stable at the voltage you have it set at.

Pll overvoltage is usually only needed to boot into windows.

If you can load windows with it off, it shouldnt cause stability problems running stress tests.

When I try to run 4.7, I definity need pll overvoltage on, although sometimes it can load windows at 4.7 with it off, it pretty random. I suspect at 4.8 it would never load with it off.
