well considering your overclock was stable with fixed settings in prime, im guessing its not your cpu(as in vcore related). when you did the prime tests did you use 80-90% ram usage or did you use the default blend settings?
i had memory sticks pass memtest86+ many times but it was still crashing due to an unstable imc. your imc shouldnt be the problem though, considering you are running at 1600mhz? i would really advise against undervolting. undervolting the pll can cause these kind of issues. i had my cpu prime "stable" with a lowered pll before and i got freezes/crashes. i couldnt really figure out where it came from till i updated bios and forgot to lower the pll setting and the freezes disappeared. try to set most settings back to "stock" and check if there are still issues(vccsa/vtt/pll/igpu)? i dont think there even are any specific tests for checking PLL stability, i could be wrong here though.

worthless? it has its uses...
perhaps not for low overclocks, or offset voltages though
