Prime GeForce RTX 5070 from Asus is a solid base for further tuning. We\u2019ll test the options GPU Boost offers. We\u2019ll measure how core and memory frequencies affect performance. We\u2019ll also look at how the power limit influences the card\u2019s behavior and how fan speed affects temperatures and clocks. Finally, we\u2019ll add tips on lowering power draw while keeping performance, or boosting performance at similar power draw.<\/p>\n

A while ago, we tested the Prime GeForce RTX 5070 from Asus. Within Asus\u2019s lineup, it\u2019s one of the more attractive options because it offers an oversized cooler, better features, and improved operating characteristics compared to the cheapest models\u2014while the premium over basic cards on the market isn\u2019t drastically high.<\/p>\n

Currently, the price of a 12GB RTX 5070 ranges between 550 EUR and 800 EUR. The Prime RTX 5070 can be purchased for 608 EUR. Thanks to the cooler and the ability to adjust the power limit for GPU boost in the range of -30% to +20%, it\u2019s a solid foundation for overclocking experiments. It\u2019s factory overclocked, but not dramatically\u2014the specified typical boost clock in the specs is increased by 45 MHz compared to reference parameters.<\/p>\n

The card has two BIOS modes labeled P mode and Q mode. The default is P mode, and you can switch to Q mode using a toggle near the power connector. The main difference lies in fan speed regulation settings; clock speeds and power limits remain unchanged, so we\u2019ll be testing with the quieter Quiet BIOS. The data and limits stored in the BIOS are shown in the GPU-Z screenshots below.<\/p>\n

The typical boost clock in both BIOS modes is raised from the reference 2512 MHz to 2557 MHz, and the GDDR7 memory runs at the standard 28 Gb\/s. The power limit is set at the reference 250 W, and you can adjust it between 175 W and 300 W, which corresponds to a range of -30% to +20%.<\/p>\n

We\u2019ll be using data from the latest version of HWiNFO for the graphs.<\/p>\n

We\u2019ll look at how basic overclocking settings affect performance and card behavior\u2014what impact each setting has on performance, power consumption, and noise, and what\u2019s worth tweaking versus what isn\u2019t.<\/p>\n

Afterburner allows both basic and advanced overclocking. It didn\u2019t work perfectly with the RTX 50, partly due to the drivers and the fact that the developer hasn\u2019t updated it since the last beta version released at the start of the year. However, according to the forums, a major update is expected in September.<\/p>\n

Today, we\u2019ll focus on sliders for memory and core clock speeds, fixed fan speeds across the range, and the power limit.<\/p>\n

We\u2019ll test each setting step by step within the range available in Afterburner or as far as the card can handle.<\/p>\n
