So I was able to get 4.8 stable with 1.5626v. Seems like the voltage is so high compared to others. This passes consistently under IBT. I would like to see if anyone can help me lower my voltages and find a path to 5Ghz. I am running a custom water loop w/D5 Vario.. lots of presure.. should be solid. - Should be. I took temp readings along the way and tried switching to FSB OCs as well. Here is what my testing looked like:
200x23
cpu:4600/1.45625 - core temp: 43c. (IBT: 266 sec)
nb:2400/1.21875

250x18.5

Current config is:
C5F FX-8350 200x24 (above)
Power:
CPU LLC:Ultra High
CPU/NB LLC: High
CPU Voltage Freq: VRM Fixed: 500
CPU PWM Phase Control: Extreme
all other at C5F defaults.
If anyone has any suggestions for how to get more umph out of my FX with less voltage I would appreciate the feedback. Thanks muchos in advance and happy holidays to all!
