RTX 4090 laptop GPU reaches RTX 5090 performance with mod
A laptop owner boosted the performance of an RTX 4090 mobile graphics processor to match that of the newer RTX 5090 by installing a resistor that enabled higher power consumption. The modification involved adding a 1-milliohm resistor to the existing component, reducing total resistance and permitting the chip to draw 240 watts instead of its standard limit.
The owner replaced thermal paste with liquid metal and upgraded cooling pads to manage the additional heat generated by the increased power draw. Benchmark tests showed performance gains of up to 35 percent compared to the unmodified configuration, with most graphics tests improving by more than 20 percent.
The technique carries substantial risks because excessive temperatures can damage components if cooling systems prove inadequate. Manufacturers void warranties when users modify hardware, making the procedure unsuitable for most laptop owners despite the performance benefits.
