Can anyone help me achieve a stable oc of 4.4 from my setup please?

Maybe its just the fact my BIOS isn't up to scratch yet, but I thought 4.4 would be quite easy.

Setup is:

Gigabyte P67-UD3 (F6c BIOS)
i2500k (Titan Fenrir /w Akasa Venom Fan)
2x2GB Corsair XMS3 1600
Hiper 580w PSU
460GTX

Things I've already done:

bclk manual 100

I've tried to research as much as possible about the BIOS options on these P67's but because Asus name things differently to Gigabyte i'm getting slightly confused.


LLC is load line calibration right? Auto/Enable/Disable?
PLL Overvolt? Is this the same a vdroop? Auto/Enable/Disable?

RAM mode? Standard/Turbo/Extreme?

vcore of ? for a 4.4Ghz i2500k?

Sorry about all the noob questions, i'm trying my best to learn on my own lol
 
Not a stress you are in the right place.


First thing you do is reset your BIOS to system defaults.

Then set your multi to 44
Leave all else on auto
Boot into OS and report back here.

Nothing else should be needed at all.

Also please specify exactly which UD3 board you are using. I say this because the UD3 latest offical BIOS is f6a
 
Motherboard is a UD3, the F6a bios gave me problems been too sensative, it kept flashing the BIOS back to F4 because of cold boot problems....

The F6a BIOS is from the website that gets bios files before they go live on manufactorers website.

I can boot into windows at 4.4Ghz easily, just fails Prime95 with BSOD after 4-5mins.

Cheers
 
There are no n00b questions only n00b answers. We are all learning about clocking the P67 so do not stress.

LLC is load line calibration right? Auto/Enable/Disable? LLC set to 1 for hectic overclocking. Not needed for what you want to do. Set to auto.
PLL Overvolt? Is this the same a vdroop? Auto/Enable/Disable? This option allows the power user to get the extreme max out of their CPU. Not really needed for 4.4GHz leave on auto.

RAM mode? Standard/Turbo/Extreme? You can set this to what ever you like once you have your basic overclock sorted. All it does is tighten the sub timings of your ram. And is ram dependant. Maybe your ram can handle extreme maybe not. But most of the time you will not even notice the difference.

vcore of ? for a 4.4Ghz i2500k? All auto for now and once you have it sorted then go into your BIOS and see what the board is setting on auto. Slowly decrease the vcore in small increments and run your stability test. Once your test fails bump up the vcore one or two notches. That should be your best vcore. But about 1.240 is normally good to go.

Cold boot problems? What cold boot problems?

This chap has posted a good guide to walk folks through he whole process.

Cold boot problems i'm having;

It takes a while sometimes to get into my BIOS. My USB keyboard sometimes doesnt fire up during POST so hitting delete does nothing, if I press restart my computer sometimes restarts itself like 2 or 3 times.....and if that happens the BIOS wants to flash back to the backup.

I've flashed my F6c to current and backup BIOS now, seems to have calmed things down :D

I'll do what you said and report back :)

What about the C1E and EIST? Just set them all to Auto?
 
Just leave them be. They make zero difference to your overclock on this chipset at 4.4GHz.


Re Coldboot - that sort of means something else to me, your understanding of it is spot on. But for me it means a coldboot bug when your system is sub zero. :D

The USB keyboard thing does happen I have read on other forum, do you have a SSD hard drive or maybe set your drives to ACHI? A PS2 connector is handy :)
 
Right assuming all was on auto you will need to change your vcore up by two notches.

Do that and then run again.
 
Is it right that my vcore in Hardware Monitor is 1.32v at idle and then goes to 1.25v under full load using Prime95?
