change system agent volts? where is my vccio?

post #1 of 4
Thread Starter 
i have a GA-z68x-ud4-b3 and while reading something online:
http://www.bit-tech.net/hardware/cpu...ore-i5-2500k/2

i came across some interesting info. in the how to guides ive read it says not to touch your system agent voltage. on the above guide it says you can adjust it. any thoughts?

also i cant seem to find vccio in my bios. heres some shot s of it:

It's right there in your last pic. QPI/VTT is VCCIO. Some manufactures aren't calling it VCCIO. On my board it's VCCSA/IO

Just keep under 1.200v for 24/7

You have changed the value already anyways.

VCCIO is the QPI/VTT I beileve and SA voltage doesn't really have to altered. Have a little READ at sin's guide.

Hope that helps



Quote:
VCCSA: More commonly known as System Agent Voltage. Intel’s maximum System Agent Voltage (Vccsa) is 0.971v and minimum is 0.879v. Stock is 0.925v. System Agent Voltage should NOT be touched, it is supposed to be a fixed voltage, and it powers many things that the VCC does not power. One of the most important is the Power Control Unit (PCU) which controls internal power allocation of the processor. This voltage is to be generated by a separate VRM than used for SVID. So on the P67A-UD7 this voltage is generated by a two phase buck analogue PWM, with 4 phases, this voltage and the VTT (Vccio) come from the same VRM(not surprisingly voltage read points are right next to each other as well).
source sin's guide.
