Are you running with turbo mode enabled? I see a lot of clock changes, and see you are attempting a 4.8ghz clock
Here is how I would set a "foundation" of sorts.
hit the BIOS, disable your power saving stuff, like C6 and C3 states. Disable turbo.
Set cpu to 20x multi and northbridge to 12x multi, for a core 4ghz and NB of 2400mhz.
Set ram to rated speed, manually adjusting clocks as necessary.
Set system voltages as follows
cpu-nb (northbridge) 1.3v
ram at spec + 0.05v (if rated 1.5, now 1.55)
set vddc (cpu pll) to default 2.5v
set nb chip voltage to 1.1v
set pcie 1.8v to 1.85v to test. If system acts goofy, set back to default 1.8v
set HTT to 1.25v I believe default is 1.1 or 1.15
Do a few test runs of intel burn test. you can right click the start button and click xtreme stress mode.
How do things look after doing this?
Now the pain in the ass part if this works for you. drop voltages. start with cpu voltages. then once you find a spot where it hates intelburn test, add a little voltage, and write it down.
Then drop cpu-nb voltage. This is a bummer to test, it will require a couple days of proper testing to do this, due to how long proper memory testing takes.
Once you nail a "lowest voltage possible" 4ghz cpu and 2400mhz northrbidge, post the voltages it took to stabilize, as far as BIOS reads and hwinfo64 reads.
Once I have that baseline, I can help you dial it in more.
Feel free to take a snapshot of the BIOS screens. If you have a spare usb flash drive, format it to fat32, most of the amd based am3/am3+ motherboards supported a snapshot feature that saves to a usb drive. If present, it usually snaps only what you see on the screen (example, will not snap the entire overclocking tab, you will have to scroll down)
And finally, please get rid of AMD Overdrive. It is buggy, slow, inaccurate, and can cause random problems when it is open. Utilize the freely available HWinfo64. The guy who created it is on this very forum as well, for any potential questions with that software
