VCore on my i5-2500k won't raise past 1.256V

[Keudn]

So today I decided to overclock my i5-2500k to squeeze a bit more power of it before I get the money to upgrade. I have an Asus Maximus V Formula mobo and I have got my core clock to 4.5Ghz without touching the voltages. At 4.6 it bluescreens, so I went into the bios and raised the CPU Manual Voltage to 1.310 and ran Prime95 again, still bluescreened. I increased the Voltage to 1.320, same deal at about the same time into the test (1-2 minutes). I currently have the voltage at 1.400 and the CPU PLL Voltage at 1.82500 and it still blue screens. In CPUID HWMonitor the CPU VCORE under my motherboard says the voltage is still at 1.256V, even though in the BIOS I set it to 1.400. Under the CPU itself the VID says it is at 1.366V, higher, but still not the 1.4V I have it at. I dropped my VCore in BIOS back down to 1.300 and CPUID still reads the same thing, 1.256V for the VCORE and 1.366V for the VID. Is there a setting in my BIOS that isn't allowing the VCore to raise even though I have it set too?

open winrar or winzip and use the benchmark. While thats running, check  your hw monitor to see the voltages.

CPU VCORE goes to 1.280V, a bit higher but it still isn't even at the default 1.3V that the VCore should be at stock, and temps are staying under or around 80C during Prime95 (I'm investing in a better cooler soon so I'll have to live with higher temps for a bit)

1,28 is not high at all on sandy, even for stock.

Im running 4.5ghz and my vcore is 1.34. 

Are you using v drop, or fixed voltage?

You need to change the load line calibration to ultra high.

From what I understand 1.3 is stock that the processor should run at without any BIOS changes, but I can't even get it to that right now.

 

I have yet to find where I can switch between v drop and fixed voltage in my BIOS, the closest I can find is switch the CPU Voltage between Manual and Offset, which is currently set to manual and the CPU Manual Voltage is at 1.325

CPU Load-line Calibration is on extreme, ill get pictures of my BIOS and post them in a minute

Uhm 500 frequency on the vrm? What the fuck.. 

- CPU voltage frequency -> auto
​- Cpu power phase control -> auto
- Load line calibration -> ultra high
- VRM Protection treshold -> back to default you turned the overheating protection off you dont want to damage your vrm.
- Xtreme tweaking -> disabled thats just a stupid thing to improve benchmark performance and causes a lot of issues
- Extreme OV -> enabled so you can play with higher clocks etc
- CPU Spread spectrum -> disabled
- PCIe spread spectrum -> disabled

Also you have putted 1.50V behind your memory but you got your memory frequency on auto? Just load an XMP profile out by changing AI overclock tuner from manual to XMP.

Changed settings to what you said, same results

My guess would be that you have a cheap PSU.

Its a corsair TX850M, unless its faulty which it hasn't gave me any problems in a year so.... And my 24pin as well as the 8pin and 4pin are plugged in, so the board is getting plenty of power

Whats your idle clock and vcore? Make a screenshot of cpu-z. Also make one more chance, go to advanced > cpu configuration > disable intel thermal adaptive monitor.

[Keudn]

Heres a screenshot of it while idling, and disabling intel thermal adaptive monitor didn't change anything, VCore is still at 1.256V

[Keudn]

Would a BIOS reflash to the newest version work? I don't want to flash unless I have too, have had some bad experiences with that.....

[Keudn]

Okay, strangely if I disable EIST, C1E, C3, and C6 the idle voltage is 1.312V and when I run Prime95 it drops to 1.256V what the hell is going on???
