Phenom 2 X3 720 - 18 °C diff btw 0.99.5.20 and .26

Post by epinephrine »

Hi,
I'm not sure if it actually is or was a bug, but CoreTemp 0.99.5.27 shows 18 °C less than 0.99.5.20 does (both 64bit) on my Phenom II X3 720 BE. I'm using a Gigabyte GA-MA790XT-UD4P Mainboard, newest BIOS ver. F5. Two of the attached screenshots were taken while prime95 was torturing my box ;) Oh, and I'm using Win 7 RC and a Scythe Ninja 2 CPU Cooler with Coollaboratory Liquid Pro.

Of course, I'd really prefer to believe the newer version .27 of CoreTemp, which also shows the same values as HWTemp (version 1.06.0 is used here) and Everest for the cores (even if they show three distinct but (of course, because there is only one sensor) identical temperatures for every core).
But on the other hand it seems, to me at least, to be more logical that the actual core-temperature is higher than the one the mainboard is reporting (here HWMonitor was used to obtain a value of 54 °C). And even more confusing is the temperature reported for the idle cores: 21 °C ?! That's just about my room temperature... impossible, isn't it? And look (screenshot) at the temperatures reported after resuming from standby - 18 °C min in CoreTemp, 32 °C min from Mainboard (HWMonitor).

Hmm, weird...

Sebastian

The only thing I can think of is that you may have set a 18C offset in Core Temp's options. Because there were no changes to the code for temperature reading in Phenoms between the two versions.

And regarding the low ambient it's because the Phenoms report CPU temps that are not "absolute" but they are with a certain - unknown offset, some people say that it's around 15-20C, differing between CPUs.

how embarassing ;) I really set an offset of 18C in .20 . For any reason I didn't check in the .20 ver, only in .27 . BUT there must have been a reason for that I earlier set an offset of 18C... AMD doesn't say anything about that offset thing?
At least I was in the golden middle between your 15 to 20 with my 18 :wink:

This means I definitely need to set an offset of about 18C, right?

Yes, they give no details. My guess it changes with different CPUs.

18C looks about right.
