Headache Overclocking 3930K with Noctua DH-D14 + Asrock Extreme6 - Page 2

post #11 of 13
Thread Starter 
Okay looks like the computer froze about 6 hours into the test.

I woke up and it appears the computer frooze 30 minutes before I woke up.
I am not sure if it was frozen. I opened my monitor screen and it detected no input. I have a led keyboard and attempted to light it up using the function key on the keyboard and it wouldn't light up. However, once I used the power button on the keyboard, a event was loggest saying kernal power failed at the exact time I turned it off. Furthermore, prime95's last log was 30 minutes before I woke up where as for 6 previous hours it would make a log entry every 6-10 minutes.

So not sure...

Any help is greatly appriciated as I am at 4.2Ghz at good temps but still can't get a good OC.

Please help!

Okay this should be the last post from me. As no one was giving me pointers, i've been trying out heaps and heaps of settings.

It either got too hot or was at good temps but wanted more Vcore or it frooze (all at 4.2Ghz).

Then I tried:

Vcore: Auto
4.2Ghz
Everything else on Auto
LLC: Level 5

Short power limit: 300
Long power limit: 300
Core current limit: 300

C3/C6/C1E/Speedstep : All enabled.

This lasted 10 hours of Blend without a problem. Max temps a little high at 77 degrees.
I am not sure why I couldn't get a fixed Vcore working.

I will be trying power settings of all: 250

If that doesn't work, I will just be using this.

Also going to look into more case fans (got 3 at the moment, going to get 3 more or maybe 4 more).

First of all i agree with Kope about the air cooler not being up to some of the higher overclocks. Water would be.
Also i`m currently running an Asrock z68 gen3 fatality with a 2600k at 4.7ghz, 100% stable since the cpu`s first appeared way back. My 1st mobo ran this too but was an Asus with the sata bug. Got rma`d for the Asrock!
Forgive me if i seem to be over simplifying things, as i don`t know you or your knowledge so i`m trying to explain as best as i can. I`m no expert by any means but have overclocked since early 2000s, with pent4 and everything else since.

Your cpu may require higher voltage to sit at idle. Imagine a voltage scale that goes from 0 volts to 2 volts and your cpu at idle will require one voltage to be stable and at load requires a higher voltage to be stable. Now imagine a small window you are looking through at that voltage list. In it you will see a max and a minimum. Move that window up and the lower volts and max volts will also go up. This would be raising the offset.
Now if your cpu runs stable for endless hours at lets say 1.35 volts when loaded (look through that window) then unloaded it will drop to the lower voltage in the window. This lower voltage may not be enough to sustain the cpu at idle and it can blue screen, even if when loaded it is 100%, 24/7 good. The only answer i know is to move that window of voltage up. Sure it will raise the loaded voltage higher than is really needed but that isn`t the problem when idle is blue screening. It is also raising the lower limit and this is what your fixing at this stage. Keep raising offset until its stable when loaded AND idle.
LLC or loadline calibration has some effect on this as it controls voltage droop and makes it less strict or more strict. This setting has to be played with and making voltages more strict (higher LLC) does not always make things more stable. This is my experience.
Also i hear from people about degradation of cpu`s due to high volts being used. I do not know if this is true or not, but i do know that a lot of people mistake what they thought was a stable overclock (but really wasn`t) and think their cpu is degrading. They just didn`t have it 100% right before, when they thought it was. I have seen pc`s run a month then blue screen, all because their initial voltage window was just on the brink of being high enough.
My advice is... Find a loaded offset voltage that is 100% stable when running prime (with temps being a point to watch when deciding whats a good limit).
Let your pc idle and do basic stuff like watch youtube, browse etc. I found watching youtube videos was a good way to test the fluctuating lower volts and would blue screen the pc if at all unstable in idle situations.
Try LLC on its 2nd lowest setting and its 2nd highest setting. The extremes didnt seem to play nice with my cpu. This will throw in a variable that will make testing a longer process.
btw i wouldnt bother with the Asrock tuning thing. I didnt and just went into the bios to do the settings. It didnt seem stable to me and just made me think it may have been contributing to blue screens. All i used was Realtemp and cpu-z, prime95.
Anyone, feel free to correct me if i am wrong in any way here. I welcome any info from more knowledgeable people!
My settings are below. I`m sure some are not necessary for the overclock but this is what they are at with me. They may be of help and may not but are from a genuinely stable pc at 4.7ghz.

Speedstep: Enabled
All C states: Disabled
Thermal throttling: Enabled
Deep Sx: Disabled
____________________
power saving mode: Disabled
Core voltage: Offset
Offset voltage: +0.100 (this was stable slightly lower but was bumped one notch after)
LLC: level 3
Dram: 1.5
PCH: Auto
CPU PLL: Auto
VTT: Auto
VCCSA: Auto
__________
short power: 200
Long power: 180
Additional turbo voltage: 0.004 (lowest)
Internal PLL: Disabled
