AMD recently launched its Radeon RX 6600 XT The graphics card is designed to target Mid-range PC gamers. Equipped with 2048 stream processors, the GPU can operate at a frequency of 2359 to 2589 MHz in the factory design.Today we saw that the graphics card has been overclocked to 2,800 MHz basic air cooling And remain stable.
According to the latest report from Igor Labs, an overclocker named Gurdi owns an AMD Radeon RX 6600 XT graphics card, which can run its chip at a clock speed of 2.8 GHz and is completely stable under stress testing.
First, the card uses a custom beta software called MorePowerTool (MPT). MPT was developed by “helm”, a member of the Igor Lab Forum, to better overclock AMD Radeon graphics cards. It enables users to switch changes that are not available in the regular AMD Wattman software, thereby achieving better overclocking.
In order to achieve 2.8 GHz overclocking, Gurdi increased the GPU power limit from 155 watts to 160 watts. This is not much different from the factory overclocking card, which means it is considered a safe range. For the GFX (GPU) core, the current is set between 127A and 130A, and the current of the entire SoC is set to a constant 25A. In addition to the GPU itself, the memory also needs a slight voltage boost. The report points out that the DPM 3 value is 1400mV. To load the settings, you need to click the “Write SPTT” button to enter the settings into the SoftPowerPlayTables in the registry. After setting the correct frequency (as shown below), the work will continue in AMD Wattman and the report shows their configuration.
If you want to understand performance, the increase in frequency has managed to provide very few extra frames for the card. Igor’s laboratory has used 3D Mark synthetic benchmark tests and some games such as Cyberpunk 2077, Red Dead Redemption 2, Godfall and so on for testing.For a full comparison, you can go to Benchmark results are hereThe card used for overclocking has entered the first sport in the 3DMark Time Spy benchmark database.
If you happen to be the owner of AMD Radeon RX 6600 XT, you can overclock your card at will and try its limits. However, please note that using 3rd party software for overclocking may invalidate your warranty and may damage your GPU, so please use it at your own risk.
