Nice to hear you got it going!
Now, you can test for a while, then see if you can use less QPI/Vtt or not. If you can't, but you want to due to temps or otherwise, you may have to lower the Uncore multi back to only 2x ram multi.
But you are fine with using 1.4 QPI/Vtt if you want, just thought I'd drop some more thoughts here for you.
Glad to hear you got things going smoothly now!
Also, these may come in handy for you to while you are tinkering around with BIOS adjustments:
BSOD Error codes and what they mean:
0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
0X00000101 << Not enough Vcore Voltage
0X00000109 << Not enough or too Much memory voltage
