Strange offset voltage depth, huge negative value needed. NO extra LLC

post #1 of 15
Thread Starter 
Ok so I have had quit a bit of time to play with my settings.My LLC is set to standard on my board and that means no intenes load line. Back to the offset question. I still after disabling LLC or using standard voltage with no offset, its almost 1.4. I believe its 1.375 or something like this. That is way to high for a 42x multiplier on water. So generally I would start with off set using negative. Why does my chip require so much negative offset to get to a lower voltage. I have to use like a high negative value just to get to 1.25. At 1.25 i ran prime and was stable with a -25 offset. My understanding is this affects idle and load. This compared to what I have read and seen is insane. I'm not understanding why my voltage is so freaking high on a 2500k on water. Basically at a 42x multiplier it think's i need a ridiculous amount of voltage on auto. Anyway this seems abnormal to compared results with others. Most end up having to increase offset not take away. I want and have tested 4.2 at 1.25 stable 8 hours prime. how can i do this while achieving power saving, or what you would call green overclocking? What I have done is set LLC to standard voltage to normal which unlock offset options. Loaded into windows and looked at load. It was ridiculously high on voltage. So at this point kept subtracting offset until I loaded into windows and got the vcore where i wanted at load which is around 1.25 -1.28. I did run prime95 stable all night. and don't seem to have lockups at idle, pc does wake up from sleep. I do not understand though why I need such a huge negative offset to get to what should be a normal voltage.

What does RealTemp or CoreTemp report for the VID under load? It sounds like the offset is not working correctly, because a -0.25V offset would push the idle voltage so low the system would almost surely crash. Can you post a screenshot of RealTemp (with the VID showing) and CPU-Z while idle and under load?

I assure you it is working and I understand how it works. CPUID or cpu-z reports voltage at 1.28 which is where i want it, however at load with no offset it is extremely high around 1.4 volts, it requires a lot of negative offset to get to where i need it. I may have made a mistake on the negative offset it might only be about negative 10 - 15 I just cant remember atm because i'm not in front of my pc but that is still a bit high for what I have.

I just know that something isn't right because most tutorials and reviews state increases by only about positive 0.05 volts which only really brings there vid to about 1.3 or high 1.2's, mine is definitely way different requires negative to get way down and no LLC. If i set voltage to auto it puts way to much on the cpu, whether is auto or offset the offset on my board uses auto voltage and offsets value added or subtracted from that. That is my issue is my damn auto voltage is ridiculously high.

Here are what my settings are at the moment. I have a vid under load Intel burn test with 1.28 and a offset of negative 0.010. Temps on load are low 50 like 51 and 52 @ 42 multiplier. Does any of this sound accurate or normal? This is with standard LLC meaning it isn't being pushed or on.

A VID of 1.28V @ 4.2 sounds about right. So you put in a negative offset of -0.01 and you are still getting 1.4V under load? Sounds like the offset isn't taking - you should be seeing something around 1.25V or so (due to Vdroop) under load with those settings. All the boards are different when it comes to LLC, where some have Auto as off and some have Auto as maximum, plus all the different names - I would just set something in the middle of the allowable range and see how that affects things. You don't really want it all the way off.

no that is at load im not getting 1.4 i only get that with no offset and auto voltage

Well, Auto is known for often giving too much voltage, especially once you get above 4.4~4.5, so that's not really unusual. What voltage do you get with the -0.01 offset - that sounds like a good setting, with what are probably good volts, and good temps, so I would just use that.

voltage is at about 1.28
