2,000 W XOC BIOS for ASUS GeForce RTX 5090 GPU Appears
The GPU vBIOS designed for extreme overclocking is generally intended for professional overclockers, but sometimes these versions become accessible to the public. Recently, a 2,001-watt XOC BIOS for ASUS GeForce RTX 5090 GPUs has emerged, enabling unprecedented power limits. This development offers multi-kilowatt-class overclocking opportunities to enthusiasts eager to experiment with their ASUS GeForce RTX 5090 cards. The XOC BIOS sets the core voltage to 1.15 V by default, regardless of the software voltage slider's position, even if the slider is at zero.
Previously, we only saw the 2,001-watt XOC BIOS for the China-exclusive ASUS ROG Astral RTX 5090D and Galax GeForce RTX 5090D HOF. This XOC BIOS allowed Galax to achieve a GPU core speed of 3,570 MHz and a GDDR7 memory speed of 2,250 MHz, boosting the effective memory speed to 36 Gbps with a bandwidth of 2.304 TB/s, nearly 29% above the standard specification. Such extreme overclocking requires multiple fused 12 V-2×6 cables or custom power delivery to bypass the connector's 600-watt limit. Additionally, custom water or LN2 cooling is necessary to prevent overheating. Installing this BIOS automatically voids the warranty, so enthusiasts should exercise caution when experimenting. This time, the XOC BIOS is compatible with the regular RTX 5090, but caution is advised when dealing with third-party BIOS, so we don't recommend it.

Wonder if that red shroud gives them an extra 3-500w or so ?
1400 Watts extra for 500 MHz? Stock 600W gets you 3GHz.
This bios isn't even intended for use with that connector, so again, please stick to the subject which is uh... I guess extreme OC and other (bad) ideas... so fair topic to bring it up in I guess. Just don't expect sympathy or blame the connector itself when you can (and do) burn up.I mean man, it's XOC. Does efficiency even matter?
My big concern is that this "works" on stock cards, which is a horrible idea to promote. Crossflashing is already a bad enough idea without adding a little under a killowatt and a half to the difference...
The 4090 matrix was a foreshadowing for 5090 pricing and power consumption. 5090 is a foreshadowing of 6090 pricing and power consumption. :kookoo:
Around 1000W was used for 3,4 ghz previously on a custom hardware modded card so 3,5 ghz is probably around the same. It's already a 66% increase over base TDP which is huge.
This is probably near the limit before the card fries before a full benchmark is possible.
Now it's norm.
This current 2kW expedition is the cornerstone for future out-of-the-box 1kW consumers GPU.
Have fan (lot's of them) running this toaster inside your PC.
Lets see how many connectors and cards will go up in smoke.
+90% of those with the money to buy that card and the required ecosystem to use it (cpu/psu), will have the funds to LC cpu and gpu,
the same way ppl buying +200k cars usually dont worry about insurance/maintenance cost.
and yeah, using 3 PSU's or so and hard solder extra wires is a must.In enterprise markets compute cards already exceed 1.4Kwh. Chips just get bigger and more refined. And they usually do more in less.
hi.
I wonder if rtx 6000 pro can be flahed with this bios .
