AMD FX 8150 Core Performance Boost - Page 2

post #11 of 17
Thread Starter 
That was not the problem. I talked to the amd guys and they said that the turbo boost overclocks all cores to 3.9 and only 4 to 4.2. The only flaw to his story is that with amd overdrive the default core boost is always set to 3.9ghz and that is for 4 cores and i can change it to 4.2 on 4 cores and get an extra 40 points on nova bench benchmark. I dont understand why i cant just set this perminately in the bios. And just to be clear i do have the turbo boost set to 4.2 in the bios.

Is Core Boost/Core Performance Boost enabled in BIOS?

Yes and I have it set to 4.2 ghz

I just don't think you're doing anything the requires it to go to 4.2Ghz. There are two boost modes. It'll boost to 3.9Ghz with all 8 cores. Then 4.2 with 4 cores. It seems like in some tests they simply couldn't get it to Max Turbo Boost. In most cases it's probably not really necessary.

hey, thanks for the link for the unparker:thumb: , i have an fx-8120 and i'm not sure why it's doing what it is, but i used to run it with turbo boost enabled (first boost set to 4.1 ghz and the second boost at 4.3 ghz). so i get into an overclocking mood once in a while so i set my cpu in the bios from 3.1 ghz to 3.4ghz and rasised the voltage a couple of notches. then in overdrive i set my first boost to 4.2 ghz and the second boost to 4.4 ghz. now we know that turbo boost will only overclock four cores, right? , wrong (at least in my case) biggrin.gif ,i ran the unparker to unpark all cores, and it did, now when my turbo boost kicks in it's with all eight cores, and wow , what a difference, and these are now my 24/7 settings, the only thing that i have to do is when my computer starts up, i have to go to overdrive and enable turbo boost and set mt settings. i have checked and double checked that all eight cores are running in task manager, resource monitor, amd overdrive, aida64, i'm sure i could easily bring the speed up, but i settled for these settings because they are not power hungry and i don't get too hot, like i said it's a 24/7 set-up. i hope you can get something from this to help you out. but honestly, it feels like i just did a major upgrade, i can't wait to get my hands on a fx-8350 and see what i can do with that. thumbsupsmiley.png


btw, when i'm not doing anything, it clocks down and my voltage drops too, and i have almost all of the power saving features in the bios disabled biggrin.gif

Basically it's based on the TDP, with up to 8 cores under load, it runs at 3.6ghz, with up to 4 cores it runs at 3.9ghz, and with up to 2 cores under load it will run at the full Turbo mode.

When i say it's based on TDP i mean running 8 or 4 cores at 4.2+ ghz will go over the 125w threshold etc

I suspected that, basically dumb windows parks/deactivates cores when they r not in use and then the windows become very resilient of reenabling them in need, so its always better to disable core parking especially for people with 6+ threads, for eg i7 owners, x6 owners and fx 8xxx owners !
And am glad that it helped you thumb.gif
