I've replaced my APU Llano config with the new CPU + MOBO.

From what I've read generally the workflow is:
0. Set preliminary BIOS options (CnQ, C6, APM etc. disabled, Thermal management Enabled, AHCI->IDE...)
1. Find the base CPU overclock i.e. overclock without touching voltage
a) using CPU Frequency (FSB?)
or
b) using multiplier
2. Increase voltages in steps
3. Smaller adjustments
4. Overclock memory
5. Final adjustments
I have followed this guide JayzTwoCents - Beginners Guide: How to overclock AMD Processors FX-8350 Piledriver which, unlike most of the other guides, doesn't fail to say what is general workflow it goes by (see the points above). It uses the 1,a) approach.
BIOS photos I took.
I tried to place the cursor at a most significant parameter I'm about to test next. If I stepped down with something it means my system failed to boot or failed to work stable.

Ad.1. My base OC.
It turned out to be FSB=245, 245x17.5~4280
FSB=250 seemed to be a no-go even with slightly increased VCORE.
Notes:
*I've set PCI freq to constant 100 MHz
*I kept CPU NorthBridge Frequency=HT Link Frequency and close to the default 2000; anything lower than 2000 always led to boot failure so I always had to choose something greater than 2000.
Ad. 2. Voltage
I've increased both Vcore and NB voltage slightly, step-by-step, along with FSB which brought me to my current 4410 at FSB=245 X Multiplier=19. CPU temperature is reaching only 55 deg C in stress.
Questions:
1. What did I do wrong up to this point?
2. How should I proceed further?
3. Multiplier OC is much easier obviously. Are there any benefits to CPU Bus frequency / NB OC with Piledriver CPUs?
I'm perfectly aware of the limitations of my hardware.
