A little tour of the world of extremeoverclocking with a graphics card and Skatterbencher. The guy in question managed to push an Intel Arc A770 Limited Edition to the limit. That’s right, we’re talking about 3.5 GHz GPU frequencies!
The Arc A770 Limited Edition pushed to 3.5 GHz!
Of course, during the overclocking session Skatterbencher used an extreme cooling solution based on liquid nitrogen. However, he had to deal with a few minor inconveniences, such as compatibility problems between his graphics card and his LN² bucket. For this reason, he plugged the card in at 90° using a riser, and fitted a CPU bucket. To protect the GPU, double-sided tape was used around the chip.
To increase frequency, the overclocker had to get its hands dirty to get around a few limitations. These included the fixed OC frequency, power limit, voltage limit, voltage throttling and thermal throttling of VRMs.
Once bypassed, he was able to serenely reach 3586 MHz (1.305V) on the GPU, but stability was not an issue. So we had to drop to 3400 MHz (1.285V) to keep up with light workloads, then to 3100 MHz to keep up with benchmarks. Incidentally, after a few runs of Time Spy, it turned out that the OC boosted scores by 26%.
All in all, 3.5 GHz on this little A770 is a good score. Nevertheless, we’re not yet up to the 4 GHz of the RTX 4090. Who knows, maybe with Battlemage things will change for the better!
