This may help, Im not sure.
Set your RAm to run as slow as you can possibly set it.
Next, set your CPU multi as low as you possibly can.
Now, start increasing BLCK. When you get to a point you crashing booting to windows, youll know thats your base clock wall, or all the MOBO is going to allow.
So then, you can set it back to default and bring the CPU multi up to normal.
Now that you know wher the BLCK start crapping out, itll be easier to determine if its the CPU or Base Clock thats the issue.
For example, if you can get to say a 200 base clock. But start having issues at 150 when OCing the CPU, chances are its the CPU thats the problem and it needs some more voltage.
Once you determine, Max Base clock and the MAX CPU OC (that you are comfortable with in reagrds to Volts and Temps) you can then balance out BLCK, or lower CPU multis to attempt to get your RAM where you need it to be.
This all actually seems quite overwhelming, especially if its your first time, i know
But you'll start getting the hang of it pretty quick and it'll be easy from then on
