LLC effect maybe.

Cant see his rig but LLC settings does that.

Kitty - LLC at high would have 0.025 Volts difference from Bios to Windows.

Giga UD3, overshoot.

Quite normal.

most FX (piledriver) cpus stop measuring temps accurately under 35C. once the cpu falls bellow that temp threshold the most common piledriver behavior is for the temps to get too low for reality. As 35C is plenty cool enough it doesn't really matter in the end.

Next, even when a piledriver is reporting its temps accurately, accurate is a "relative" term. You see, piledriver cpus, like all amd cpus since the phenom II don't actually have a "real" thermometer on the cpu. It uses some mathematical algorithm to estimate the chip temp. furthermore, on piledriver that correctly reported temp is pretty reliably -10C cooler then the reported socket temp on a motherboard.

now this is where it gets confusing because you'll see things about safe cpu temps. Typically those temps are given as core temps (65C) and socket temps (73C), generally at 65C reported core temps your cpu will start to throttle itself IF you left that option turned on in the bios. Meanwhile your motherboard typically will start to throttle your cpu when the socket temp hits around 73C (regardless what the bios is set to do).

since the socket temp often lags behind the "cpu" temps, usually taking 30-60 seconds to catch up and stabilize, there still is plenty of value in keeping an eye on core temps. Assuming your piledriver reports it's core temps accurately anyway. not all of them do. If your chip doesn't then you'll have to rely on the socket temps to guide you.


EXTRANEOUS AND UNIMPORTANT INFORMATION:
To further complicate things, people like to analyze what the piledriver package/core temp is really reporting. Because of the higher socket temps it's assumed that the core temp doesn't really refer to core temp but rather the SURFACE temp of the cpu heat spreader.

This is great information which will help new comers to this club, can I use this information and credit you as I'm putting a OC guide together for the FX chips? I'll be asking around for information around summer time (when I have more free time) and then hopefully we can put it on page one of this club etc.

All I managed to find about it is this:

"Starting with the Phenoms, AMD's digital sensor no longer reports an absolute temperature value anymore, but a reading with a certain offset, which is unknown. It is estimated that this offset is between 10 - 20c."

Hope it helps.

It isn't down to you what people do in their personal life, sorry but saying things like that is really absurd. Are you going to stop me swearing in real life because it's against your own moral position? The answer is no.

@3DVu

Talking about RMA's through overclocking and voiding your warrenty is against the forum T&C so I'd be careful if I was you, you might end up getting a warning or infraction which may lead to a ban. It's frowned upon here so be wary.

Yeah I found that too, a lot of people find that the temps can be way off like you said, it's really confusing and temps are relative to what we need to know in order to push our chips further. Temp is relative to stability and voltages you see due to voltage leaking from the silicone within the CPU, that's why sometimes you can see some people have low voltages compared to your own if they have better cooling but obviously there is the luck of the silicone lottery too.

I honestly just use core temp as a comparison for the socket temp, an algorithm is absolutely inaccurate. I hope they also fix this with Zen.

It isn't "absolutely" inaccurate thought I understand why you would believe this as I have done in the past, I use a combination of both socket temps and core temps to work out what is happening, also with HWinfo64 I use the graphs to help see where my temps are sitting properly as the min and max reading used to throw me way off base with temp spikes etc.

You could also use a second monitor and dedicate it to HWMonitor, CPU-Z, GPU-Z or whatever you use.

When I benchmark and/or game, I usually dedicate my second monitor to HWMonitor and GPU-Z to see the GPU load
