vcore vs QPI/VTT voltage?

post #1 of 7
Thread Starter 
hello all, love the site and forums.

i have a question concerning voltages on my computer, which is a z68 chipset gigabyte Z68x-UD3H-B3 to be exact, with a intel i5-2500k.

when i initially started overclocking, i reached 4.4 ghz easily without touching the vcore, while disabling the required features. clocking higher produced unstability in prime95, which i started bumping up the vcore like what i read from guides, but still proved unstable. i noticed in HWMonitor that my CPU Vcore was still saying 1.06 even when it was under 100% load on all cores. after reading a bit last night, i set my Vcore to "normal" and adjusted the QPI/Vtt Voltage to 1.205 and HWMonitor and cpuid now says my vcore is 1.21.

my question now is, before i try any stress testing and possibly hurting my system, is this the correct way to increase the voltage and not using the vcore like it seems so many others have said?

i can post any screenshots or anything you need. if this is something previously covered and ive missed it sorry for the time a link in the right direction would be greatly appreciated.

Justin

+rep thank you ken
edit, well i would give rep to you if i was allowed to yet:P

Alternately, look at this thread OC guide with Gigabyte boards with all the glossary.

http://www.bit-tech.net/hardware/cpus/2011/01/07/how-to-overclock-the-intel-core-i5-2500k/4

Btw, just FYI, the Rep+ button is replaced with the thumb button on the new platform.

unfortunately even with this links, after adjusting the right things in bios will vcore go up to the intended amount on hwmonitor:( is this a sign of a faulty mobo?

i am thinking of reverting back to award f9 bios update, as i read of a possible OC issue, worth a try eh?

Did you overclock your RAM or set the XMP? If so, it will set the QPI/vtt too.

I can confirm it does not change the controller voltage on my z68xp-ud3, Once i realized this and manually changed it myself I stopped having all of the post loop issues that were occurring.
