Now, it was time to move on to tackle other world records, but this is the point where things went south. Jonathan and team moved to the 2,500W XOC BIOS, but they had an earlier revision of it, which pushed too much voltage at once to the GPU and, as a result, one of the samples ended up dying. The core was visibly cracked — likely from sudden thermal shock.
Only 1.2V killed this 5090, which is fine for negative temps on liquid nitrogen, but incredibly dangerous at ambient temps around 25 degrees. The core, therefore, cracked because of a temperature imbalance where one part of it was cold while another had transformed into a hotspot. Anyhow, that's roughly $5,000 down the drain, but Jonathan has four more samples to resume testing.
Speaking of which, the overclocker did not manage to break any other world record, such as 3DMark Solar Bay Extreme. A better, more securely mounted cooler is required to continue with the remaining PCBs; Jonathan says at the end of the video that he might try a regular retail BIOS that's more stable, too. As for the dead 5090, it can technically be revived with a donor core since the rest of the componentry is intact.
