2600k & LLC

[BioVirus87]

Guys i need your help, why is it if i set the line load calibration to ultra high on my Asus p8p67/2600k set up i require a cpu voltage of 1.41v to be stable @ 4.8 (which underload drops to 1.392v)
but when i set it to extreme i can set cpu voltage in the bios to 1.375 (which underload increases to 1.392)????? can i have peoples opinions on what would be the prefured setting ultra/extreme

it seems that my cpu requires 1.392v underload to be stable @4.8 which in my bios is set to 1.41v using ultra high LLC is there any advatagesin just using the high LLC setting

It just changes the amount it adjusts it by under load

Same on the UD7 on the highest setting it ups the vcore so i use the 2nd highest.

I have mine set so that its at 1.41v at desktop and then it drops to 1.38v underload.

1.38v is what i need to be stable at 3.8Ghz

If i were to use the setting that ups the vcore then i would need to be at less than 1.38v at desktop so that when it goes up it didnt go higher than 1.38v.

Problem there is when idles its only getting say 1.37v so isnt stable.
End result can be prime stable for many hours only to crash when at idle

Was the same on my ramapge formula 775 board too.

Does seem a very big drop on mine...maybe a bios issue that will get changed next update.

Better to have a high voltage on cpu when its idle than high when its flat out...thats my take on it anyway...i am sure others will see it differently

Would prefer to set it at 1.38v and for it to stay at that underload but thats just the way it is.

Sorry for the thread hijack


I thought the idle crashes and hangs were due to the cold boot problem so to speak, the proccessor would reach a low temp at idle then just freeze.

please correct me if i'm wrong as i've only just started reading up on them

and do you think i would notice a big difference in gaming moving from a 3.8ghz 955 BE to a i7 2600k at around 4.2 Ghz
