2600k won't boot past 4.4ghz...?

post #1 of 31
Thread Starter 
OK so I'm no noob to overclocking, I've taken a 2500k to 5.2ghz on air before.....but this 2600k seems to be fighting me.

Anything past the 44 multi, it will post fine but just get stuck with a cursor blinking at the top left of the screen.

I've been running 4.4ghz at 1.325v as the daily OC for awhile now. VTT is at 1.3v (ram at 1600mhz 6-7-6), and PLL I've tried anywhere from 1.7 to 1.9v with no difference.

I have C1E, Cstate, and speedstep all disabled.

Do I have like the worst clocking 2600k on the planet? I've tried up to 1.4v Vcore for 4.5ghz. And I'm running a megahalems so temps aren't an issue either.

Motherboard is an ASRock extreme6 smile.gif

did you say you put 1.7v into your CPU?

try enabling internal pll overvoltage. also, make sure your powerphases and all that stuff is set to extreme (if your bios has that) also, make sure llc is enabled.

reason your computer posts just fine then freezes at windows login, is because the overclocked turbo multiplier doesnt kick in until windows starts to load. Up until post your running on stock multi.

Why do you need 1.325v just for 4.4 ghz? Is that your load voltage or your bios set voltage? Do you even know what vcore you're getting at full load?

If that's your load voltage, your cpu probably is a bad clocker and needs Internal PLL Overvoltage on for 4.5 ghz or higher. (this has absolutely nothing to do with the PLL voltage, btw)

PLL voltage... but that still goes through your CPU, aye?

True, but 1.7v for pll is nowhere near harmfull.

I did try the PLL overvoltage enabled, didn't help. LLC is enabled.

It's not on the stock multi at POST, I have the post screen disabled and it'll show the CPU at 4500mhz in the POST screen.

Well it's set to 1.31v with LLC it goes to ~1.325v under full load stress test in CPUz. Yeah I need this much voltage, at 1.30 I got a BSOD after 1/2 hour of stress.

Tried enabled PLL overvoltage as I mentioned above.

1.7v is undervolting the PLL. 1.8v is normal.

Wow, I know you aren't new to overclocking so I would have to guess that may just be the worst 2600k on the planet... The blinking cursor usually means it just won't go higher on the multi.
Can the mobo pump enough voltage to kill it & get a better replacement?

lol.

It only goes up to 1.52v, with LLC I guess that'll be 1.53-54v so that'd be no. I could run it without the heatsink...haha. No I wouldn't do that anyway lol.

I guess I'll pump the voltage higher and see if it'll go more. Thats ridiculous! Maybe I'll try turning HT off as well.
