Windows 7: Repeated BSOD's Last 3 Days

The choice is yours.

All the numbers in the first BIOS screen shot look ok, except the 'CPU NB VID Control' in the second screen shot that says the voltage is reduced by 0.075v, this needs to be changed as mentioned below.

All hardware performs differently, including RAM.

If you think about the number of different brands of hardware available, let alone the fact that the same brand hardware performs differently (A-Data RAM with all specs the same, will perform differently).
How can the motherboard and BIOS optimize any settings for your specific set of hardware in your system?
The reference list would be enormous, let alone how would they adjust for the different performance for the same spec hardware.
The statement in your BIOS means that they have generally optimized voltage for general hardware, not for the hardware in your system.

Somehow the 'CPU NB VID Control' setting was changed to -0.075v, default settings after OS installation will be 1.100v on 'Auto', for all RAM, doesn't matter the brand or number of cards or total GBs installed.
This is the problem, the more GBs on each RAM card require more voltage, more RAM cards require more voltage.

If you would like conformation on this, Google your motherboard part number and 'Ram settings' or your motherboard part number and RAM part number.

Gigabyte forum and any overclocking forum will give similar suggestions. You can also serf RAM sites to find these same recommendations for your situation.

I have seen hundreds of recommendations for BSoDs, on many RAM manufactors forums to bump the RAM memory controller voltage.
It works, unless the RAM card is bad.

My recommendation is to increase the 'CPU NB VID Control' voltage to 1.150v, you can do this by selecting the +0.050v in the second screen shot above.

The choice to do it is, of coarse, yours.
