What do you guys think? This is on an ASUS P8Z77-V Pro. I'd really like the ASUS readings to be true

I have the same ASUS program on my motherboard.

It's uninstalled now, readings are wrong. Go with RealTemp temps, I had the same discrepancy.

The RealTemp readings are probably true, though there's really no way to be sure. The only truly accurate number you're going to be able to pull is deltaT, which is fine as tells you how far you are from overheating anyhow.

When I tested this, I noticed every other program I installed matched except with the case of the ASUS one.

Check your idle temps in the BIOS, they will even disagree with ASUS probe.

Distance to Tjmax is ALL that matters. Realtemp is reading that from the CPU.

The actual temperature is just calculated from Distance to Tjmax, so you can just use that.

Tjmax for IVB is 105, be sure Real temp has that setting correct and those will be the correct temperatures.

RealTemp is set correctly at 105C. Bummer, I had 5+GHz on my mind when I saw those temps.

They are reading different sensors.

Realtemp and Coretemp read both tjmax and distance to tjmax directly from MSR on cpu, and will give accurate core temperature since calibrated at intel (though may be less accurate at low end since calibrated at high temps), and core sensors are located in hot spots.

The CPU temperature/sensor is not core temperature/sensor. CPU sensor is located between cores, away from hot spots, and is more of a general cpu temperature. It may be accurate, or not, as there should always be a significant gradient (especially on these) from core hot spot (core sensors) to between cores sensors (cpu). However cpu sensor is NOT calibrated by intel, it is calibrated by your bios, and is subject to all sorts of error. CPU temps should always be significantly below hot spot (core temp) sensors.

Just a side note ... is your cooler OK? The first thing that struck me was that your temps looked high to me.

What are your ambient temps and what is your cooler? I am still in the process of tweaking etc, but my 3770K @ 4.3 (1.15V) running at 100% load never got over 52C in 10 minutes with ambient temps around 20C and a H80 for a cooler.

Ambient temps were mid 70s Im running a Hyper 212 Evo

Wow those temps are high for only 4.2ghz. I should have kept my 2700k

Ouch....Looks like air cooling IB's with HT enabled is gonna be fun.

Was the temp from LinX or IBT?
