My assumption is that this temperature doesn't properly utilize the Tj,max offset.
Can i give you a dump from HWinfo or do something so we can check it maybe?

I'm afraid that won't help to determine which of those values is really correct.

IS CPU Package power a better read to determine CPU power draw or would IA Cores Power be better?

Yes, the "CPU Package Power" should be the total CPU power consumption. IA Cores Power accounts only for the x86 cores, so "CPU Package Power" ~ "IA Cores Power" + "IGPU power" + SA/uncore + all the other components in CPU.
But note, that those values do not work properly in case SVID is disabled (used commonly when OCing >125 MHz BCLK).

So CPU Package Power would be good in determining how well the CPU cooler is doing by cooling the watts the CPU is pulling? I would imagine this wouldn't take into consideration total system consumption when looking at just CPU stress due to additional power draw from the memory and actual motherboard?

I need a kill-a-watt meter...

"CPU Package Power" accounts only for CPU power - more precisely it's the current drawn by the CPU multiplied by actual voltage.
I don't think this is a good indicator of cooling, CPU Core/Package temperatures are the ideal indicator for that. Though as a secondary indicator to assess how much power (under a given load) is being cooled it might be useful.

I am a little confused I am fairly new to Intel but I noticed there is not actual turbo settings for the clock. I thought that with intel you set a main core clock and a turbo core clock if turbo is on. On this motherboard if i set turbo to off the core remains at stock 4.0ghz. If turbo is on then whatever I set all cores (or single cores) to is what it sets to. Sometimes however it will boost up to 4.9+ghz and I also see the bus clock jump to as high as 102.3 which of course increases clock of ram which always is reflected but it does not always reflect the bus clock increase in the CPU clocks as shown here at 101.3 bus is what it went to which it reflects the jump in the ram and pci-e clock but not in the uncore or the core:



I am not sure why it bumps it up or how to control turbo? Little confused and wondering if this is normal? Any help appreciated smile.gif. (build in signature, Intel overclocker)

Hey Martin, I'm facing something similar, meaning (anyway) I'd like to ask why my Bus + PCIe Clocks often derive from 100 MHz. I've explicitly set them at 100, in the BIOS. Screenshot taken a couple of hours ago. And of course, CPU Spread Spectrum is disabled. IF this is a software inaccuracy, please explain why it cannot get fixed (because I assume that if it could get easily fixed you would have already done so).

I'm also aware that disabling Periodic Polling would result in reading the Bus Clock only once and thus always keep it at 100 MHz. What I would like to know though is IF my BCLK + PCIe does actually fluctuate or not... Can you answer this for the i7-4790K?

Thank you.

PS: IF it helps, I'm telling you that in the screenshot my system is running a per-core OC.

On all CPUs before Skylake, the BCLK is measured using software methods - there's no dedicated hardware logic that would measure it independent and then read by software. So it can happen that occasionally this measurement doesn't read precise data. This is because Windows is a multitasking system and if some other applications take a lot of resources this can have influence on HWiNFO relying on precise timing while measuring this clock.
This is different with Skylake, which finally allows hardware-assisted much more precise reading of BCLK (independent of other software).

Thank you, Martin!

So, what I understand for my i7-4790K is that Intel is not providing an appropriate method for accurate BCLK detection / measurement and so it is not HWiNFO's fault for what we (occasionally) observe. I also perceive that if BCLK is explicitly set to 100 MHz in the BIOS, this "glitch" can be easily ignored and, IF inconvenient, Periodic Polling can be always disabled.

Keep up the good work! thumb.gif
