Lost my OC'ing virginity to my i5-2500k! Stability help needed

post #1 of 17
Thread Starter 
I need some help getting my system stable, check this post for more info.

So yea, I guess the title says it all kinda Bought new PC parts like a week ago, got them on Friday and have been stabilizing and oc'ing ever since! Here's the result (might not be 100% accurate since I just ran Prime95 just to make the screenshot):

When it comes to STI, sleeping with one CPU, is sleeping with many.

Have not! I did have help from a friend though, does this make it a threesome?

Apparently it's not 100% stable yet though. Ran 11 hour stresstest over night with 0 errors in Prime95, but now that I'm actually on the PC again it's locked up twice so far..so I upped the voltage a tad bit. Hoping that'll help.

I seem to be having issues stabilizing my system >.< Last night I had Prime95 running for a good 11 hours on these settings without any errors:

CPU Voltage: 1.18v
DDR Voltage: 1.5v
VCCSA Voltage: 0.95000v
VCCIO Voltage: 1.05000v
CPU PLL Voltage: 1.85000v
PCH Voltage: 1.05v
Load-Line: High

After I woke up I just turned off the stresstest, rebooted just to be sure, and then just went ahead with what I usually do. Play games/browse interwebs/msn. PC locked up twice while doing that (within like an hour or so) so I decided to pump up the CPU Voltage to 1.185v, and that seemed to work fine all day until just now. PC locked up AGAIN.

I'm quite clueless as to what to do now. I just upped the CPU Voltage to 1.19 now, DDR Voltage to 1.55 and CPU PLL Voltage to 1.90000.

I'm somewhat concerned about my vcore as I don't really know what the limit is I should be going for before really damaging my cpu (now or over time). Currently the vcore with the settings I have them on right now is Min: 1.34v and Max: 1.38v.

Any tips/hints/tricks?

what mobo? are you OC'ing using turbo? i.e. your cpu should be downclocking while idle

Fill out your system specs if you don't mind. It will make it 200% easier to help you out



Also, intel has said that the Max vcore is 1.52v, so you have some room to add if necessary.

I also put my vcore on auto as I was having issues with the vcore not going up after the chip would idle... at 4.5ghz my core is usually 1.38v or something around there. I'll check when I get home from work though.

Using the ASUS P8P67 motherboard. And yes, It clocks down to 1.6GHz while idle.

Working on filling that out right now.

-Edit-
I'd also like to know what temperatures are acceptable and at what temperatures I should start being careful etc.

Enable PLL overvoltage if you want to go for 4.8 or above, at 4.5 I would leave it on Auto.
LLC to ultra high to ensure you get the voltage you select
Extreme Phase Control to make sure the board delivers the juice under load
Extreme duty control on 4.8 or up, T. Probe for 4.5
Manual mode for voltage try 1.2 and work your way up from there.

I'd also put the rest of your voltages at Auto for now, no need to start changing things just for the sake of changing things.

Everything else should be fine at auto. If you BSOD write down the STOP code and put it here. From what I remember, 101 and 124 = MOAR VOLTS!

As to your temperature questions, that comes down to how willing you are to fry your components. The TJ Max of the chip is 100C, but I'm sure serious degredation would happen as you approach that temp. I always go with 72C as my max in a 24/7 rig on air. No, I have no explanation for that temperature, it's just my designated "max safe".

Edit: I'm a bit surprised at your 61C reading in that screenshot after that little of stress testing with your cooler. Are you sure you didn't put on too much TIM when applying it?

As I said, that screenshot is quite inaccurate due to me just launching Prime95 (only 2 tests have passed on that screenshot). Lemme upload a new screenshot for ya.
