Easytune increasing my temperatures

[Barber1996]

After using easytune on my gigabyte z97p-d3 and after resetting to defaults my temperatures are too high with low cpu usage.I've read that easytune causes errors on the cpu.Is there a way to get low temperatures? (Temps right now are about 45-50 celsius while cpu usage is under 20% and without any overclock) Thanks in advance. (CPU is pentium g3258)

Best to OC manually in the BIOS, most of these autotune, auto OC things set voltages higher than needed - which results in more heat

I found that the high temps were because easytune enabled Spectrum Spread, and for some reason that increases idle temps.

I turned mine off under the "BCLK Adaptive Voltage" setting in the UEFI, on my Z270X-Ultra Gaming. I know this is an old question, but I couldn't find the answer anywhere so now I'm posting it everywhere that lead me to eventually find it.

Kirby - can you screenshot this in BIOS and post it? I have a Gaming 3 and don't think I have this available in my BIOS.

It might be named something else. Apparently they like to change the name for it every now and again on gigabyte boards, and some don't have the option atall. I'm pretty new to all this myself so I can't help with too much detail but on the Z270X Ultra Gaming Rev 1.0, F2 BIOS ver., this is the path to BCLK Adaptive Voltage http://imgur.com/a/OmY61

Apparently on some it's found by pressing Ctrl+F1 while on the main BIOS menu for extra options but I can't speak about that from experience.

If your CPU FSB clock doesn't vary more than a few MHz either side of 100MHz or whatever it's supposed to be then Spectrum Spread is probably not enabled as it is, so that's one way of checking at least.

Thanks - I'm curious beacuse I was looking to see if Spread Spectrum was ENABLED or DISABLED in my BIOS but I could not find this setting in the F6 BIOS on the Gaming 3. Thought it might be buried somewhere.

Don't know much about Spread Spectrum but here is what I read:

"The only reason we implemented spread-spectrum was to reduce manufacturing costs. That allowed us to be more competitive and It allowed us to more cheaply meet the technical FCC requirements for "home" and "office" FCC emission rules. The "rule" of the regs if not the "spirit". TEMPEST is a whole other deal.

Anywhere a manufacturer can save a nickel or more in BMC (Base Manufacturing Cost) it's highly desirable (esp when you're talking about millions of units). Spread-spectrum could save multiple BMC dollars per unit, even after factoring in the cost of implementing spread-spectrum control circuitry and firmware.

Spread-spectrum allows manufacturers to continue to have relatively high RF emissions which SUBSTANTIALLY reduces the cost of manufacturing (reduces need for physical shielding, EMI "fingerstock" and "braid", wear-resistant plating and conductive paints (in the case of plastic cases), case fitment tolerances, case vent mesh, wiring shielding, cable RFI ferrite cores (clip-ons or permanent), and so on. If you look at pre-spread-spectrum PCs with plastic cases, you'll find some that used very thick copper and other metal-based painted coatings on the inside surfaces specifically to meet FCC regs...this was very expensive stuff and it required special handling and disposal during manufacturing (also added to the cost).

By simply spreading out the emitted RF energy over a wider frequency range in which peak and mean values were generated manufacturers are able to more easily comply with the RF band-specific FCC regulations."

Stuff

Sounds exactly like what I got from my research. A hack-around half assed method to avoid FCC regulations by spreading out the interference.

Totally unnecessary and counter to a tightly functional system. Lol. Also, unbeknownst to anyone from what I can find on the net, a contributor to high CPU 0% idle temps.
