Do you have your power settings in windows set to balanced? Your multiplier should drop to 16 and idle vcore to 1.00v or lower.

Oh yeah that did the trick! 0.864v in CPU-z at idle.
I dont think I have ever changed that before, it was set to ASrock extreme tuner utility I'm guessing that's standard when installing the software or something.
Anyways it seems to be running smooth far, I turned the fans down to 800RPM when I went to bed and max temp was 71c after running P95 for almost 15 hours, when I run the fans at full speed the temp is in the 50's so I'm definitely confident in running this 24/7.

Thanks for the help Lucky 23! smile.gif

Hey folks,

Need some advice, seems like i am hitting some black hole above 4.5Ghz. My goal is to get 24/7 stable @ 4.8GHz

I am currently rock solid stable @ 4.5Ghz for 2+ years, follow the guide just to make sure most settings where accurate.

Currently running CPU Voltage offset: +0.005v & Turbo voltage: +0.012v I can run 24/7 regular use & gaming at 0.005v Offset & 0.004v Turbo but Prime stable requires 0.012v Turbo.



I will post BIOS screens later when i get home.

Something i don't quite get about Vcore vs VID in HWMonitor. Everywhere i read people say that VID is baked in at the factory and doesn't change but i can see it constantly changing in HWMonitor. VID also seems extremely high @ 1.42v Max. I also read that Vdroop can be calculated based on the difference
between VID and VCORE, but does that mean i need a negative offset? My LLC is set to "Level 3" i believe....

Is VID just something the CPU is requesting based on the Turbo/Boost features being enabled and VCORE is what the CPU actually gets on full load?

As you can see i am a bit confused rolleyes.gif ... CPU boots fine at 4.6GHz, 4.7GHz, 4.8GHz but get a BSOD pretty quick when running prime for ~1minute with 101 error (meaning increase vcore?)

My temps are quite manageable topping out at 62C after hours of Prime95....any suggestions are welcome to try and get this sucker stable at ~4.8Ghz

VID is in fact cooked in by intel, if you are using offset mode, it will fluctuate depending upon your load/multiplier. think of it at a set curve in a graph of multiplier x vcore, and the + offset as moving that curve up and the turbo voltage as only moving the furthest point up.

The higher you go with multiplier, the more VCore you need inbetween each step. For instance, you might only need an addition .030 to get from 4.5 to 4.6, but to get from 4.6 to 4.7 you might need .40 or even more. The scale of voltage needed increases rapidly after 4.5, so if you are getting BSOD with 101...yeah, you need more VCore.

Edit to add: you dont have much headroom. 4.5 @1.300 is not horrible, but you will be pushing the 1.45 range to get it stable at 4.8

Thanks for the quick reply! I think i am starting to understand what you are getting at.

As you can see in my screenshot, my VCORE under load is 1.32V but VID is 1.42V. a difference of ~0.1V seems huge.....should i try setting a negative offset (i.e. -0.090v) or lowering the LLC level?

Someone help me with the Math here:
Voltage offset: +0.005v
Turbo voltage: +0.012v


How does this work out to 1.32V??? Isn't the CPU stock 1.2V? so 1.2 + 0.005 + 0.012 = 1.217V or is the LLC feature driving it up?

Maybe 4.8GHz is out of reach but seeing my temperatures relatively low, so far, i feel pretty comfortable pushing the VCORE to ~1.4V (i just get nervous seeing VID potentially show 1.5v....or is this nothing to worry about?)

Also, The Guide on the 1st page suggests to set:

Long Duration Power Limit: Max
Short Duration Power Limit: Max
Primary Plane Current Limit: Max
Secondary Plane Current Limit: Max

The Max works out to 500, but i see most screenshots have the values set to 250. Should i drop these down?

P.S. This 2500k has already served me well for 2+ years and if i shorten its life a bit with 1.4V, i won't loose sleep over it.

Max the limits, other people are just being lazy. Dont worry about VID, it is just an arbitrary reference point for which we set overclocks. How many volts and what temperature you are comfortable running is all up to you. There is some gray area there, but if you dont mind the trade off of shortening the life span of the chip....run it! I did not own a sandy, but I abuse my ivy with 1.4ish for 5.0.

Ok cool, so i should just keep pushing the Turbo Voltage until i start seeing VCORE jumping above my ~1.4ish V comfort level? I guess i can enable PLL for 4.6+GHz just to see what happens...

Should i not even worry about changing LLC (currently Level 3) and potential negative offset then?

Wondering if I would have any issues with BSODs if my Windows Power Settings were on High Performance instead of Balanced? I never have my computer sleep or do any power-saving since I just have no use for it but wondering if that may be related to the issues I could be having in my rig.

no relation. what is the BSOD code?

Negative offset will affect your idle vcore as well as your loaded vcore, there are a few specific cases where negative offset can be a benefit. In your case, you are going for a higher overclock, so unless you have a real high idle vcore, negative offset is just likely to cause hard to diagnose idle stability issues. As for LLC, moving to LLC2 or LLC1 without touching voltages will increase your vcore, but might be just the bump you need.

There isn't a real BSOD code thanks to Windows 8.1 just having a very vague error of WHEA_UNCORRECTABLE_ERROR. Not much help but tested the CPU, motherboard and all sticks of RAM and none of them are faulty.

Add a little VCore...WHEA is a good sign that your overclock is unstable. But just barely unstable.
