Amazing. I don't know the architecture since I don't have a 5090 but how are you able to pull LN2 scores with chilled water? There is no thermal throttling? Also, how are you getting around limits? For example, look at OGS in #2 - he has a Galax card - we can assume they supplied a special BIOS or it has a software utility that allows him to work the magic - but I don't even see an Elmer's EVC connected to your Astral so how does it work? ASUS supply an unlocked BIOS? Sorry for the dumb questions - like I said - no 5090 RTX for me yet so super ignorant at the moment. Maybe this is like the situation with ECC on 4090 RTX?
Anyways, amazing score - congrats.
