I've never heard of any problems regarding the VCCSA voltage setting, on what information are you basing your warning on? Do you have a link for that?
Intel's spec allows up to 0.971v, so I don't see why you shouldn't increase your setting up to that voltage if all other options like Vcore, VTT or PLL fails. It may help after all (though it probably won't).
Sin even recommends up to 1.1v for VCCSA in his IB guide for air/water cooling, although personally I wouldn't go that high.

Right from Sin0822:

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

That's Sandy Bridge you're referring to, apparently things have changed with Ivy.

No they are the same for both chips.

The range Sin0822 refers to is what Intel will allow, but it should only be changed when using LN2 with advanced users who know what they are doing.

As a general rule, though, my quotes still apply. Vccsa should not be altered.

Is this acceptable? This is a screenshot of IBT but p95 temps are about 65 max. I cannot g3t it stable with less vcore.

Pretty good.

Make sure on any test that you include/use at least half your installed RAM.

In your case, that would be 8GB.

The temps look great! That Raystorm is treating you right. thumb.gif

My main concern is "Is that vcore gonna be too much?" I don't wanna burn up my chip.

Use the limits I provide in the guide.

Thanks, I will definitely stay away from that 1.5
