Problem with unstable OC on I5 2500K

post #1 of 12
Thread Starter 
hey everyone, I've already done a thread but was advised to come in the CPU section as it should more people.
Here is the link to the previous thread: http://www.overclock.net/t/1358213/need-help-overclocking-my-rig

Anyway, I've been trying to overclock my I5 2500K after doing a Bios up date, and it keeps being unstable. I'm afraid that my Vcore is starting to be to high.
I've taken a few screen shots of my bios so you guys could see what I've done.

I manage to use HyperPI and intel Burn Test with 30 pass no problem, but I keep crashing under OCCT and prime95.
Also my max temperature under load is 73°C.
Any idea on what I should modify to get a decent stable OC with a lower Vcore?

You can try changing Vdroop Control from Auto to something in the middle of the range (whatever that range is, percent, names, whatever). Also, can you post a screenshot of CPU-Z under load? 1.36V is about right for a 2500K so you might just need a tad more Vcore. You aren't too high at that speed though.

My guess is that Vdroop is bringing your load voltage down too low.

this.. and add also a tad dram voltage so it is just a little over 1.5v, also i know from ramsticks that needed just a little more voltage in some combinations.

Ok so I've jsut changed the Vdrop to low (it was the only available option), and I've changed my Vcore back to 1.355 and just passed the IBT with 30 pass which is a first with the Vcore this low.
My previous "stable" Vcore was 1.375.
Here is the screen shot requested: http://i275.photobucket.com/albums/jj287/curtisslach/cpuzunderload_zps31e00801.png


Going to change the Dram now.
Should I also OC the ram or it's not worth it?

its not worth it, i would only set my blck to 100.01 so it stays always over 4.5ghz ^^
the 0.01 more blck are nothing, but if errors from nowhere occur switch it back biggrin.gif

your OC looks absolutely OK

Looks good. I would just run the RAM at the rated speed (unless you have some of the super easy ot overclock Samsung stuff). There is not much performance benefit to overclocking the RAM.

It' is still crashing, so right now I've upped my Vcore to 1.370V, we'll see if it crashes or not.
I'll give an up date once I manage to get a stable OC under 1.4V.
Thanks for the help

if it still crashes try it with lowering PLL from 1.8 standard to 1.7 or 1.75.
but first enable PLL overvoltage.

Ok final results, I've just done 5hours on OCCT with my Vcore at 1.380V and no crash. I think I can say that my OC is stable now. I'm still going to run prime95 for 12 hours.
What do you think of that Vcore? is it to high or is it just fine?
