I want the single threaded performance for the needs of DX11 titles and that was usually needed on 1 core. My guess is the game that i usually play - WoW got a new game patch and that could have resulted in more threads being spread equally across the cores thus the system OC's the 4 cores as it needs. I will check some other games tonight to see how they behave.

Just dropping this here:
If the chip runs hot with fixed Voltage, it will also run hot with Turbo Boost ON when the chip goes into berserk mode. Especially when you said 4.6 is already too hot for your liking yet, you are gunning for 4.8.

Are you really getting that? IMO it should at least be marginally stable at 4.8 fixed and runs within the thermal bounds or you will simply push it to fail, throttle, and cause you issues.

You first need to dial in the max clocks that your chip can handle in a fixed clock and Voltages before doing an adaptive Turbo Boost mode. Why?

Simply put it, there is a big chance the CPU will turbo at the max clock if it is stable and within thermals wiyh a heavy threaded load. And there, your system will give out better performance even in single threaded apps due to the fact that each instruction can be executed once and not repeatedly due to innate error correction.

Errrm. We feast in stable overclock proofs rather than max verification shizzle! biggrin.gif

Most of us need to back down the max clocks a bit during certain times of the year. Nothing to be ashamed of.

i know, but booting with 1.432v is not bad i think, but indeed i did a step down

Booting is one thing. These chips are not like other CPUs that the Voltage needed between a Validation run is not too far away from being stable. thumb.gif

I could cool my 1.5 V 5 GHz 8320 and 290X with only 360 mm rad space smile.gif

I think his psu would poop itself at 5 ghz on the cpu and pulling a 390x with any kind of load.

This looks pretty promising. Zen vs broadwell E in blender both at 3.0G Zen comes out on top barely

Having APM on at all tanks multicore horribly. A static overclock, by contrast, beats a much higher APM-on overclock (4.4 static beating 4.7 APM handily — probably even 4.0 beats 4.7 APM-on).

I tried everything. Mild turbo overclock. Big jump for the turbo. Disabling cores. One integer core per module. Etc. etc. The TDP problem was unavoidable and disabling things tanks multicore, too. If you're running a 220W TDP or something then that's a different story, I guess.

APM is worthless, its like the power limit on newer GPUs. You can do overclocking with turbo/c-states without it on the right motherboard.

Good to see , thanks for sharing that

EDIT: the only downside is , i probably wont be able to afford it....lol
