First time OC, 4.4 @ 1.325v is that too much? i5 4670k

Sounds like your chip made above average chips possible.
1.3 is about the highest vcore for 24/7 operation.
I looked, but could find no official intel info.

One thing you might do is test with OCCT.
It uses a set of instructions that are more normal than the ones used for P95.
