Ok update,
I have tried the following
Replaced Motherboard with new one same model- issue still exists
Replaced power supply- issue still exists
I tried another Gskill, this time 3200 c14 ram that was listed on the qvl and same problem with instability. Realbench will run for about 5 mins then it detects instability and if i run the test again the computer hard hangs then reboots.
Increased the soc to from 1.1 to 1.2v it ran for the longest it had but still hangs and crashed.
I have tried manually entering the timings and voltages and also docp
Adjusted Soc loadline calibration to Level 4 which keeps the Soc voltage steady at 1.2v under load
Seems the more voltage i add to the dram the more unstable have tried 1.3-1.4v range.
Tired typhoon burner and Dram Calculator's "safe " timings- same problem
System runs completely stable with ram at default 2133mhz settings
Could it be my 3700x?
