IA voltage went from 1.455V to 1.506V.ĮVGA advertises an '1800MHz Boost Clock' on the RTX 3090 FTW3 Ultra (vs. Upon removing the offset, the frequency remained the same but voltages jumped to ~1.40V to ~1.41V with a max package temps lingering ~78✬ to ~80✬. I discovered this was probably because I forgot to reset/disable the core voltage offset in XTU. Throughout the first couple of weeks the system experienced a crash and executed an auto-reboot three times. After enabling and allowing the system to learn the CPU limits, all-cores clock frequency topped at 4.9GHz with core voltage sitting at ~1.35V to 1.38V and average CPU temp plateauing at ~70✬. When winter came around, ambient temp now is ~21✬, I decided to try Asus's AI Overclock. At 100% load, the CPU package temp settled at ~68✬ with core voltage ranging from ~1.28V to ~1.31V. By default, the i7-11700K has a single core Max Turbo Boost of 5.0GHz and an all-core Turbo of 4.6GHz. FYI: The ambient temp averages ~24✬.Īlso during the summer/fall heat, I undervolted my Intel rig's 11700K to keep temps lower. :) Indeed, I don't normally run the system that way. The CPU does hold ~4.8GHz all cores (for the most part) though. When enabling PBO (auto limits), the under load CPU almost immediately jumps to ~96✬ - obviously, the thermal wall. If the graphics card is also active, that value ramps up another ~10✬.

I previously posted a brief AMD PBO test:ĭefault/stock OC/boost: my SFF rig with 5600X cooled by an NH-U9S maxes out in the low to mid 70s C. Corsair's iCue software as a secondary reference for monitoring sensors. So, I decided to experiment on the 'one-click' AI-based masters. However, in the past 10 years auto OC features have emerged. As much of an enthusiast as I am, I have yet to believe manual overclocking is worthwhile.
