^^^ 8320E is a 95watt chip.
OP, share pictures or snaps (giga should have an option to save bios snaps to USB flashdrive)
Start with something known very simple. set cpu voltage to 1.25 volts, cpu multiplier to 15 (3ghz core), northbridge to 10x (2000mhz) and HT link to 2400mhz. Ram to 1333 or 1600, what ever it defaults to.
Test in windows to be sure these settings took place, using HWinfo64.
Once verified these settings took place and stuck, save this clock profile inside the BIOS. consider this your baseline.
Now go back into windows, use HWinfo64, and leave it idling for 5-10 minutes. Note resting voltages for vcore, ram, northbridge (might be labeled VIN2), 12v rail, 5v rail, and 3.3v rail.
Now hit it hard with a blend prime95. Remember, this should still be the low voltage 3ghz core setup. Again, watch voltages and temps. This time, simple read the max after an hour. Now note the averages. FX chips will sometimes post a peak way above what you expect (example, real max voltage spike might be 1.36, but HWinfo64 sees a single one time spike to 1.4, this is where averages help out a lot).
Once you figure out the differences between BIOS settings and actual (as close as software can see, at least), use this information, and because of your motherboard, Id recommend a max of 1.4v vcore.
Use the ram voltage to find out if BIOS settings need a boost at all. Use the 12/5/3.3 rail voltages as a sign if things are getting hit hard. If 12v and 5v rails suffer, Id go nowhere beyond 1.35 vcore, and focus on getting ram and northbridge speeds as high as possible. They will make more impact when core frequency is blocked from finding its true temp limit.
