How accurate is CPU-Z Core Voltage reading?
Most everyone seems to list their CPU-Z reported core voltage when they post their stable overclocks and I was just wondering how accurate is that reading compared to the actual you set in the BIOS? On the Asus P6T7 I have I'm using 1.375v on a W3520 with Load Line Calibration disabled and my reported load temp in CPU-Z is 1.304v. Is that close to what it actually is with vDroop since LLC is disabled?
I'm just wondering since it's hard to compare sometimes what the normal voltage is for a given clock when one person lists the voltage reading in CPU-Z as the voltage they use whereas another may list what they actually set in the BIOS.
Its accuracy is hit and miss. In my system for instance my DMM reads 1.224V when set to 1.225V, and CPU-Z reads 1.508V.
Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
Random Tip o' the Whatever
You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.

well I believe its about 3 decimal places
seriously though, it depends on the board your using and the particular voltage setting, the only real way to tell is DMM'in it up
