I'm trying to OC my AMD FX-8120 black edition on my Asus Sabertooth 990FX.
I went into my BIOS and I've disabled all the "green" settings, set everything to manual, and I increased the CPU ratio to 20 (to get 4 Ghz, something that was easily stable for me when I tested it in AMD overdrive utility).
Now, it shows the target CPU speed at 4 Ghz, but the Current CPU Speed isn't changing (still at 3.1 Ghz), even after saving and resetting (via F10 key).
When I run CPU-Z in my OS, it still has the Default Turbo speed of 3.4 Ghz and a 17x multiplier. (I have disabled the automatic turbo core boost in the BIOS).
Am I doing something terribly wrong or just incredibly stupid??? Thanks for any suggestions!
Here are screenshots:
Is it possible that this is the case because I previously had AMD overdrive installed? (I set it back to default settings and uninstalled it)
Also, I noticed it saves my settings if I set it to DOCP instead of manual in the BIOS, and this works fine showing a 20x multiplier in CPU-Z. My only concern is the DRAM OC speed of 1600 mhz, since mine is only rated 1333 mhz.

yeah I was reading someone else having difficulty with amd overdrive lingering.
may want to default your bios. start in safe mode. uninstall the over drive, look for left over files. run a ccleaner(or what have you). restart into windows. then restart and go back into your bios and try again.
...oh yeah and disable the apm, if your cpu is throttling. I had trouble with it on the fx6300
Thanks for the help all; I was able to resolve the issue by switching over to DOCP mode and inputting the values that way (After that point, I was able to change values in manual mode as well).
I have also disabled APM now as well.
