Yes, change the 'CPU Vcore' to 'Normal', this will enable the 'Dynamic Vcore(DVID)' (Page #43&44 in your motherboard manual).
Dynamic Vcore will add/reduce voltage to the Vcore and allow the OS to change it for Stepping and other features. When you manually set Vcore it will remain at that voltage setting regardless of other functions settings. Much better to use Dynamic Vcore for CPU voltage setting adjustments.
increase the CVID by +0.010 untill stable?
Yes, this is a best way to get it stable, some people are impatient so the 0.05v and then reduce by 0.010v until un-stable and bump up 0.010v works better for them.
If the system boots into Win7, test with one of the CPU testing apps.

CPU - Stress Test with Prime95
Be sure to monitor CPU temperatures, don't go over 77.6°C.
Open Prime95 and stop the test if it is running, in Advanced tab select 'Round off checking', in the Options tab select 'Torture Test...', in the window that opens select 'Blend', after 'Number of torture test threads to run' enter 4, then click OK to start the test.
Run Prime95 for two hours, this will be enough for this stage of testing.
After the above adjustments are finished and stable.
We can adjust the VTT and DRAM voltages/settings.
The Intel rule for VTT and DRAM voltages is to have DRAM 0.50v(or less) above the VTT. This is to prevent damage to the IMC (CPU Integrated Memory Controller), this is well documented.
Check the 'Command Rate' setting for the RAM, should be 2T. If not then change it.
EDIT: The previous CPUZ Memory tab shows it is set to 2T already, check it and confirm.
Set the VTT manually to 1.120v.
Set the DRAM manually to 1.500v.
Check for stability, if it boots up with no issues then run memtest86+ for 7 full passes, best to run overnight.
You can stop the test if you get any errors, one is too many.
If these settings fail to boot or won't pass memtest86+, then bump the DRAM voltage to 1.550v and test again.
Edit:
As mentioned by MiTr, it's a good idea to check for bent CPU pins.
