AMD overclocker pushes the Radeon RX 9060 XT to 4,643MHz with internal tools

AMD's Radeon RX 9060 XT has reached another extreme-overclocking milestone, with overclocker Bill "Sampson" Alverson pushing an engineering sample of the GPU to 4,643 MHz, about 48% above AMD's listed boost clock. The result is reportedly the second-highest GPU frequency ever recorded, just behind the current world record of 4.769GHz.

That world record belongs to AMD and overclocker Splave, set on the same card at 4.769GHz. Sampson did not beat that record this time, but the result still puts him in rare company. Only two discrete GPU overclocking runs have ever exceeded 4.0GHz, and both involve the RX 9060 XT.

The card used for this run was an engineering sample, and the screenshots show custom AMD internal software being used for liquid-nitrogen overclocking. One visible command references "L1N2control.exe" with settings targeting 4,650 MHz and 1,610 mV. These appear to be non-public AMD utilities, firmware, or BIOS modifications that allow far greater control over voltage and frequency than standard tools like MSI Afterburner would ever permit. The motherboard used was reportedly an MSI board, though the exact model has not been confirmed.

The screenshots also show the GPU running at 4,643 MHz, with a chip temperature of around -49 degrees Celsius and a voltage of approximately 1.6V. That voltage figure is the detail worth paying attention to. Retail software does not allow voltages anywhere near that level, and for good reason. In normal use, running at 1.6V would cause the power draw to spike dramatically and generate excessive heat density, degrading the chip quickly. This only makes sense under extreme overclocking conditions, where the goal is to hit a record, not to maximize the card's longevity.

The RX 9060 XT already runs at high clocks in standard use, with boost behavior reported around 3.1 GHz. Jumping from that to over 4.6GHz is an enormous leap, but it shows the frequency headroom sitting inside the Navi 44 design when pushed to its absolute limits.
