Did I lose the silicon lottery? 7900XTX OC.

I've recently started trying to get a teeny bit more performance from my Sapphire Pulse 7900XTX. The card has been fantastic, I just want to see how far I can push it. I've been using Cyberpunk as a test and playing with the settings in Andrenalin. I know settings the power limit to +15 and adjusting the voltage down is a key point in OCing these cards. I hear most can hit 1050mv but I can barely hit 1080mv. Anything less than that and CP won't even start let alone run a benchmark. 1070mv it will start but crash during the benchmark. I haven't even gotten to messing with the core/memory clocks yet. Is it just a case of bad luck or am I doing something wrong? The PTM7950 I put on the card has done wonders for it's temps so I don't feel like that's the problem. The highest I've seen it boost to was a little over 2800mhz.
