We knew we were playing with fire with the RTX 50-series. When you pack that many transistors into the Blackwell architecture and push 600W+ out of the box, things will get toasty. But what happened this week with the MSI RTX 5090 Lightning Z isn’t just a burned-out card; it’s a physics lesson in why silicon has limits. An overclocker managed to physically crack the GPU core of MSI’s powerhouse flagship card. He fed it more power than the laws of thermodynamics allowed.
Alva Jonathan Killed a 100 Million Rupiah Graphics Card
The card in question was an MSI RTX 5090 Lightning Z—the most powerful on the planet, designed mainly to chase world records rather than play Cyberpunk 2077. Out of the box, these GPUs come with 800W and 1000W operating TDP profiles, but Alva, as shown in his YouTube video, pushed it to a 2500W “XOC” BIOS meant for extreme overclocking. That’s enough power to run a small apartment, funneled into a single silicon chip. This model has dual 12V-2×6 power connectors, which should have been our first warning sign, and a theoretical power limit that makes your breaker box sweat.
He used liquid nitrogen to keep temperatures sub-zero while cranking the voltage to hit record-breaking speeds. It actually worked for a second. The card managed to achieve the highest Geekbench 5 score ever recorded before the physical stress became too much. Where it went wrong is Thermal Shock.
Pushing the card to 1.12V and nearly 1,000W of power resulted in a 3.42 GHz clock speed, 1 GHz faster than the stock boost clock. However, you have to keep the temperature in a small Goldilocks zone. If it gets warmer than 20°C, it crashes, and when it dips below 0°C, it becomes unstable. Keeping it under 10°C was the only way to maintain the high clocks. He managed to reach 3.6 GHz during a GPUPI run, but the current HWBot world record (683,433 points in Geekbench 5) was set at 3.5 GHz.
While chasing more records, he tried a 2500W XOC BIOS that pumped nearly 1.2V through the chip, and the GB202 core couldn’t take it. The temperature delta was too aggressive, and the GPU die went from “frozen solid” to “surface of the sun” in milliseconds. Silicon is hard, but it’s brittle. The fast expansion caused by the voltage spike clashed with the sub-zero state of the rest of the die and snapped. The physical silicon cracked apart, a $5,000+ graphics card turned into a keychain ornament in the blink of an eye.
Obviously, there’s no warranty coverage for this. You don’t get your money back after bypassing power limits and pushing 2,500 watts. With the non-MSI RTX 5090 Lightning Z BIOS leaked yesterday, people will be tempted to flash it onto standard cards. Don’t. Most RTX 5090s are built for 600W, not four times that amount. Unless you want to see your GPU explode, stay away from XOC BIOS files.
