Use this form to post:

Motherboard: [Value]
BIOS Version: [Value]
CPU: [Value]
RAM Speed: [Value]
RAM Slots Taken: [Value]
RAM Size: [Value]

Spread Spectrum: [Value]
Multiplier: [Value]
BCLK: [Value]
Core Current Limit / Primary Plane Current Limit: [value]
- for a i5-2500k:
- 112A for 4100MHz
- 125A for 4500MHz
Please set Core Current Limit or Primary Plane Current Limit. This helps a lot with stability!!! First set your desired multiplier and start from 100A for example or lower. If you see that in IBT you are not reaching your multiplier you have set, raise it by 5A until you have reached your multiplier. Setting this to 300 required my computer 1.36v to be stable. Setting it to 125 required only 1.31v for my setup. For Ivy Bridge you might want lower values. In my opinion it's there for a reason. To prevent crazy current spikes for example. So use it.
Fixed/Offset: [Value]
Voltage: [Value] (Fill in here the offset or fixed voltage)
Turboboost Additional Voltage: [Value]
Load Line Calibration: [1/2/3/4/5]
CPU PLL Overvoltage: [Auto/Enabled/Disabled]
CPU PLL Voltage: [Value]
VTT: [Value]
C1E: [Value]
C3: [Value]
C6: [Value]
C-State Package: [Value]

Requirements
- System did not crash for one week or longer during normal usage or idle. This is to prevent idle BSODs in your overclock.
Prime95 27.7 or later BLEND up to 90-95% of RAM
- 18 hours of 15min / FFT gold standard
- 12 hours of 10min / FFT minimum
This is the most important part. to test.

- LinX (Intel burntest) is superior to Prime95 small FFT for determining CPU core logic stability.
Must run with the IBT thread count set equal to the physical core count of the CPU.
HT slows it down and reduces the ability to determine stability. Set to 4 threads on a 2600K.
Set memory to "All".
Stability Criterion: Must pass 5 cycles minimum, passing 20 cycles is preferred (considered gold standard)
Prime95 large FFT is superior to LinX for determining L3$/IMC stability.
Must use large FFT, blend is insufficient. <- reports indicate this is false for AMD stability tests, see post #4
HT is ok for this test.
Stability Criterion: Must pass 2 hours minimum, passing 12 hours is preferred (considered gold standard)
HCI memtest is superior to LinX, Prime (large or small), and memtest86+ for determining memory stability.
Launch one instance per thread supported by CPU (8 instances of HCI memtest for 2600K)
Set each HCI instance to use an appropriate fraction of the memory...16GB on a 2600K means each HCI instance (there will be 8 instances) are to use 2048 MB.
Stability Criterion: Must pass 200% coverage minimum, passing 1000% coverage is preferred (considered gold standard)

Please don't chit chat here. I am going to make a spreadsheet and upload the results. So I could make nice BIOS templates.

Why
To prevent newbie questions. They can easily start using these templates or aim for them. By this spreadsheet it is also easy to see what others are having.

My OC is apparently unstable, can I take it back?
Yes you can, edit the spreadsheet, find your line, and delete it. The last column contains your user name

Contributions or suggestions
Feel free to add more columns or make request to add more things. I hope to make a great overclocking experience and prevent questions like why is my overclock not working.

Feel free to add your OC to the spreadsheet below... MAke sure to post your OC in this thread also

hi there.. lets do this

Motherboard: Z77 Extreme6
BIOS Version: 1.50
CPU: 2500K

Spread Spectrum: Disabled
Multiplier: 45 ( Per core! 45 45 45 45 )
BCLK: 100.0
Fixed/Offset: Offset
Voltage: +0.015
Turboboost Additional Voltage: turbo disabled
Load Line Calibration: 2
CPU PLL Overvoltage: disabled
CPU PLL Voltage: 1.832
VTT: 1.094
C1E: enabled
C3: disabled
C6: disabled
C-State Package: disabled


my first stable setting.. brainwashed for over a week to find them
i also use prime95 64bit v27.7

with some older versions i got always an error after 30mins with customblend 1344/1344 and 80% of ram

Voila added to the list! wink.gif

Added a link and allowed everyone to edit the spreadsheet.

My overclock is also coming. I have 1.32v for 4.5GHz using LLC3 -0,025v offset

For 4600mhz i need at least 1.36v so I skipped going so far.

updated first post with extra requirements like RAM.

If you feel other options are missing for the template let me know

Good idea! i will add mine soon! Do u want the highest Ghz or my daily?
Bedankt! wink.gif

i guess it´s about the daily..
but u can also add the benching / suicide value biggrin.gif

Suicide without effort, im aiming for 5.5 but its not booting for now.

2500K 5.4ghz:

Suicides count, but they must be 24/7 stable. Your rig must be stable for one week without even one BSOD. Also it must be tested under Linx, IBT, Prime95



Updated first thread again with extra guideline requirements for testing stability that should work.

I am finally stable at 1.33v 4.5ghz using offset and llc3 biggrin.gif Still I have to test 7 more days tongue.gif
