With only 3 options it wont take long to determine LLC stability. I would personally start at Level 1 and check. If it's unstable then bump it to Level 2. I'm guessing it'll need level 2 but it's just a guess. Since there's no need to push additional voltage where it's not needed start with 1 though.
What board and CPU do you have?
Also... Read this thread. Nearly identical board. The BIOS will likely be the same or damn near.
Nah its ok i can overclock it to x57 BUT when i did it PC will freeeeze on starting windows or in windows it self this happen when i choose more then x44 nvm i ll make some picture and i ll try disable those C1/3, speedstep, CL6 when i ll come to home
P.S.: Why Windows Task manager showing me 4,9Ghz and other programs like CPU-Z showing me 4.3 ?
1. Player, I'm not sure why CPU-Z is showing the variable multiplier if you have turbo disabled but I would trust the actual clock displayed. i.e. 4.5Ghz or 4.6Ghz. We generally consider 1.35v safe so long as you have adequate cooling of the CPU so just monitor your temps regularly. Remember when summer comes for your area you may experience higher temps and might need to drop this OC down a touch.
2. I've never heard of Dynamic Vcore either so I did a quick search her and came up with this. TL;DR : Looks like it might be Offset Vcore
3. I would enable LLC. It doesn't increase temps very much but will allow the board to feed increased voltages if necessary.
4. More Stable? In my opinion you are either stable or you are not. But the answer to your question is yes more voltage and more cooling. However you are approaching that higher than recommended voltage point. I personally would not go above 1.35v unless I was on a custom water loop or better. JMO
5. Overclocking your ram is a whole other adventure. I would recommend making sure this OC is completely stable before proceeding to OCing the ram. Also I would start a new thread for that. This isn't the thread for that.
6. Frequency isn't what kills CPU's. Heat does. So long as you keep your CPU cool and not to overvolted you will be fine to run it 25/7 at these settings. Naturally all electronics have a life span but from what we've seen mild to moderate OCing doesn't shorten the life span. Heavy to extreme overclocking, well, that's a different story.
You're very welcome Player! This community has taught us all so much that it feels good to contribute and give back when we are able. Best of luck and feel free to start up a thread with some results. We may be able to fine tune your OC even more.
If windows is freezing up on you then either your OC is not stable or your Windows is corrupt. It's most likely your OC.
The Ninja4 is a good cooler and should be plenty for this OC.
You should set your ram to 1333 until you get your system stable and then work it up to 1866. The 1333 and 1600 max you are talking about does not include overclocking ability. You should be able to get to 1866 with no trouble but for gaming purposes (assuming thats what this rig is for) 1600 is more than enough with the i5-2500k.
All right thanks ill try down rate mine Rams and i ll see but still dont UNDERSTAND why pc will freeze should i increase Vcore?
Dynamic VID setting allows the Vcore to work dynamically using the CPU VID, so the voltage does not have to be fixed at maximum all the time, the Vcore will go up and down according to CPU load, multiplier, temp.What is meaning Dynamic Vcore(Dvid) on my motherboard?
