Why is lower dram voltage making my build more stable?

[wweerr123]

I overclocked my cpu to reach a stable state first, then when enabling the xmp for the rams I encounter instability. Weirdly, increasing dram voltage(to 1.36~1.38) only makes it worse, but decreasing it to 1.34 actually makes it stable. Why is that? Does it have something to do with my vccio or vccsa settings? Any ideas?

Overvoltage is a thing you know, I know my Hynix A Die does not like too much voltage, while Samsung B-Die doesn't mind a lot of voltage.

An example was I upped the voltage a bit, had it on 3200Mhz, it was stable for a good 30 minutes then crash, there's a near hard limit for some dies.

The ram has a xmp profile with 1.35v. So I thought 1.35~1.38v shouldn't be too much for it to handle even though I overclocked my cpu. Ram being stable at 1.34v certainly surprised me. I'm also wondering if over heating vrm is the real culprit .

That's kinda odd to happen at voltage this low (expecting more around 1.6v for Hynix stuff), but more voltage doesn't always mean better stability indeed.
