Try these for 4.2Ghz with memory at 1600
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

I don't have a link to your ram, so the above is just a general guess. 2000Mhz is not ideal for your CPU to use for daily 24/7 settings, so 1600Mhz sounded good for now ;D
Below values may be left in Auto if you like, generally this is fine. For those users who DO Set advanced timings manually, please see some of my thoughts and findings about these settings and rules here
