The picture is of my Zotac Solid Core OC 5080 2975mhz at .975v +3000 mem 105% power usage (380w). It pulls about 360w with this undervolt and gets this score.

One thing that is strange is that if I didn’t apply an undervolt and just let it run free with a +285 core clock applied with the same mem and power settings listed above, it will only score 9500 with a 3030mhz at 1.01-1.02v. It refuses to go out to its max of 1.05v, however it will hit that in games with a core of 3175mhz at 1.04-1.05v.

In comparison, my Astral OC 5080 scored 9952 with no undervolt, +3000 mem, 112% power (450w). 3270mhz at 1.07v.

My question here is, how can my Zotac at a much lower core clock score almost as good as my Astral with a much higher clock?

My second question is undervolting my Zotac barely lowers its power consumption and when running Steel Nomad, it’s using its full 360w at 3075mhz and 1.015v. Why is it hitting its power limit so early when bench marking?

I had another Zotac solid core oc 5080 that I had traded in for the Astral. That card would only use 260w of power with a 3105 at .975v and would score a 9200 in steel nomad.

TLDR: Zotac Solid Core OC 5080 scores higher in benchmark than exact same model that could get a higher core clock. Also scores almost as high as 5080 astral that has a much much higher core clock. Looking for someone who good knowledge of overclocking and GPU binning to explain my findings.
