Your chip is an eo, they are all different but you should be able to get those clocks on way less voltages. Honestly I would set everything in motherboard voltage control back to normal and start your oc over. What worked for me more than anything was to set cpu termination to 1.2 then raise cpu reference and mch reference up 1 notch. After that raise the cpu termination as needed but leaving the reference voltages alone, they will increase as you raise the cpu termination. I was able to get 3.7 prime stable on stock vcore, 1.2 cpu termination .785 cpu ref. .80 mch ref., 1.24 mch. 333 strap 5:6 devider on the ram. See how high you can go on stock vcore then raise voltages as needed from that point.

these are my current voltage settings for 4.0 prime stable no LLC.
Hope that made sense.

this really helped

I guess it’s time for me to go beyond stock , is this a good starting point template for a Q9550@3.4 guys?
