Hello,

I've been trying everything to overclock my i5 2500k to 4,5 ghz today. I've looked at several tutorials, and the one on this forum also.

Gigabyte Z68XP-UD3
Intel i5 2500k
CM 212 Hyper Evo + extra fan

I start by setting the multiplier to x45. After that i change the VCore to 1,325.
I set the LLC to lvl 5, so the voltage to the CPU is constant. (I've also tried lvl 4 and 6, but none of those worked either.) I disabled all the powersaving stuff. I didn't touch the bclk, because everybody else doesn't. And i didn't do anything to the chipset voltage either.

As I see it, I've done like everybody else in my position trying to overclock their 2500k, but here's the thing...
My computer automatically restarts after the "loading operating system" message, and never shows the windows logo. Have I done something wrong? (I have, but I need some help pointing out my mistake) :o

Please help
Regards LeGraudal
 
Try more volts I use the same board and my 2500k needs 1.365v to be fully stable at 4.6ghz. Also make sure your memory voltage is set correctly mine autos to 1.5v but needs 1.6v to be stable.

With a hyper I would keep an eye on the temps at 4.5ghz + although its a good cooler something a bit more meaty may be better.

Thanks, will try now and post the results when i'm finished.

EDIT: I tried, but failed again. The BIOS screen shows a clock of 4,5 ghz and it reboots just after the bios message "loading operating system"
What's a safe Max VC? Because i find it strange that i'd have to exceed over 1,35V .

EDIT 2: Should i turn of the Over Current Protector?

If you can control the temp then 1.4v is ok but with a Hyper I would go easy with the volts. Try and find the best stable overclock and tweak from there.

I'm not at my PC but from what I remember I have my Over current set to auto, I also clock mine on the boost clocks and leave the cpu clock at 33x (Stock). My power limits are set to 300 and I use LLC level 6. When I get home later I will check my settings.

How do you clock the boost clocks? what settings are they?
 
I based my overclock on this but tweaked a few settings here and there. If you are on the new Uefi bios you are buggered for overclocking as most of these settings are not available.

Oh my god, are you me?

I have the same CPU, same motherboard too and I can't break 4.4GHz without insane amounts of VCore. I need around 1.35V for 4.4GHz but 1.4V+ to hit 4.5GHz
 
Nope, I can't even get the UEFI without formatting a memory stick (because somehow none of the other methods work).

I'm using the F8 BIOS, and just concluded that my chip sucks.
 
Ahh I have just realised my board is the GA-Z68XP-UD3P. It seems the P makes all the difference and my board is a different one completely.
 
If you have the GA-Z68XP-UD3P try the settings I linked above. I need 1.365v for my cpu to be %100 stable.

Your settings have the multiplier at 33x though. What overclock did you get with those settings?

I need around 1.35V VCore and level 5 LLC to get 4.4GHz and to boot at 4.5GHz need 1.4V and level 6 LLC. Obviously that's not something a Hyper 212+ can handle (although I'm probably going to get a Thermalright Silver Arrow SB-E Extreme soon).
 
I use the boost clocks to overclock. I leave my Multi at 33x at set the 4 boost levels to 46. My CPU still clocks down when not on load but all cores boost to 4.6ghz under load.

INTEL BOOST TECH [ ENABLED ]
RATIO 1 - 4 [ 46 ]

I use 1.365v and LLC level 6. With either a Noctua D14 or H80i the temps remain under 70.c.

Under advanced settings I think there are 4 values you can set. Mine are all set to 46.

Just to check are you using the UEFi bios ? It's the one with mouse control and pretty graphics.

Nah, I'm not using the UEFI, since i'm not able to update my bios for some reason.. Using the @BIOS utility that came with my board though... I'm gonna try to flash the oldfashioned way later today. Sry, my late response. None of the above posts have granted me any luck with the overclocking, since nothing of them has worked.. yet.

EDIT: I was able to update my BIOS to F10 from F8. I got an bios read error every time i tried installing the UEFI version. So i've gotta go with the F10. Going to try OC'ing again now. I'll keep you posted.

I don't think I'd even noticed that you could set the boost levels :o

I have power saving options enabled anyway (they didn't affect my system stability), so my CPU downclocks to 1.6GHz at idle anyway. I'll probably play with the boost functions when my new cooler arrives this week.
