Sense MI Offset skewed tCTL for me, which in turn skewed SIO CPU Sensor as well, I also played with T_Offset.

Here is screenies zip, only 1 setting played at each time.

V5.50-3130 would be fine for readings.

T_Offset is a pretty straight forward offset, isn't it? So does Sense MI Offset apply some kind of curve, which is responsible for temps to increase slower the higher they get?

No, there's no fixed offset possible (except from AMD side). Both options adjust the scaling (hence skew), different methods with the same end result. I don't recommend using T_Offset, mainly due to worse granularity.
post #9214 of 17092
Why are both applied at the same time then? T_Offset for the big scaling steps and MI Offset for the small ones?

Did you see my earlier power vs. temperature screenshots concerning "fixed" AMD offsets?

I'm am trying out Pstate overclock for the first time and everything is seemly going well except for one thing. In my windows power settings, there is no minimum or maximum processor state. I've manually edited the registry to add the values that can be found everywhere on the internet but it doesn't ever seem to take. I've tried looking in all 4 of my presets to no avail. Interestingly enough, the CPU parked cores option that I added via registry works.

So basically, I have Pstate set but windows is keeping my cores from downclocking and I can't figure it out.

Gotta be something wrong the the tempreporting. Tried all available hardware tools and they have all swown the same.

Up until now i have ben runnning the stock spire cooler and unless i throw 1.5 volts on the cpu, i can't get it warmer than 55c, but the cpu refuses to go over 3650 stable. Found an old terrible aio cooler from Corsair (you know the old thin radiator one, that got recalled i think). Drilled a few holes on a weird backplate so i could fasten the block. Did that and the temps are only 8c cooler on the cpu at the same voltage (1.419, it droops to as low as 1.337, but pretty stable at 1.356). The major difference is the socket temperature and the motherboard temperature in HWinfo. These are MUCH lower than before, without a physical reason really. All of a sudden, i'm looking stable at 3.9 ghz. Not sure what to make out of this really, but a combination of cool cpu socket and the cpu itself is much more important than at least i though.

I would start with good airflow over the whole socket area if you have similar issues as me. Maybe even under the mainboard, but that may show a false positive number i think.

Can't wait to mount the EK hardware as that gotta be a hundred times better than this stinky old AIO.

Turn off Sense Skew in BIOS and check again.

elmor, again thank you for all of your work AND your willingness to share it on this forum. I got my C6H mb with 902 BIOS native and upped it to 1002 release. I "braved" it and upped it to 081 beta and it has run perfectly. Of course having the Gskill FlareX DDR4-3200 ram (2x8) sure helps. I'm solid at 4Ghz and ram at 3200-14-14-14-34-1T.

Awaiting the new official release of the updated BIOS.smile.gif

Look at my screenshot. I'm already using it.
