Accurate Voltage/Temp Monitoring

post #1 of 5
Thread Starter 
Hey, I read a post somewhere around here the other day that seemed to indicate that CPU-Z v1.56 doesn't report VCore correctly for Sandy Bridge. Is this correct? If so, what does report it correctly? At load, mine is currently reading around 1.32v. Relevant settings for sig rig are: Offset (-0.015v), Additional Turbo Voltage (+0.040), Internal PLL Overvoltage (Enabled), Load-line Calibration (High - 50%). Both HWMonitor and SpeedFan generally agree with CPU-Z.

Also, I've noticed that when I sit in the UEFI (1305), it reports (idle?) temps as around 45C! RealTemp/CoreTemp/HWMonitor say ~33C. Who is right?

I do not have ASUS's AI Suite II because it absolutely refuses to install. And, before you ask: Yes, I have run the patch file. Twice.

I managed to get AI Suite II installed and here is my current situation.

Current Settings
CPU Voltage: 1.23 (Manual)
Load-line Calibration: High (50%)

Readings under Prime95 Blend
CPU-Z 1.57: 1.192-1.208v
HWMonitor 1.17.0: 1.20v
AI Suite : 1.20v
RealTemp 3.67: 1.3361v (is VID different than VCore?)
CoreTemp 0.99.8: 1.3361v (also VID)
HWiNFO32 3.71-1190: 1.3361v ("CPU Current")

Who do I trust? Normally I'd go with CPU-Z/AI Suite, but they are both showing lower than expected voltage even though LLC is enabled.

Software is almost always a little bit off when compared to measuring with a multimeter, usually pretty close but there can be exceptions.
I had a classified x58 board that would set 1.66Vdimm in BIOS, software would show it at 1.648V in windows, but when measured with a dmm 1.69V. On the same board the VTT voltage would read a couple hundred mV higher in software than what was shown in bios or measured with dmm, actual voltage was very close to what was set in bios.

yea software is never 100% especially for the PSU.

my X58 GB boards are almost dead on, but for P67 they are dead off. it is scary, people are seeing 1.53v when its actually 1.57v

It's odd, because with 1.23v manual and high LLC, I'd think it would run around ~1.28v. Instead, CPU-Z (et. al.) reports 1.192-1.208v under load and 1.248-1.240 at idle. I even saw it jump to like 1.256v at idle once. Why are my idle volts higher?
