If you are the proud owner of a processor from the Core Ultra 200K range, Intel has you covered: the manufacturer is offering a new overclocking feature dedicated to this series of “Arrow Lake-S” CPUs, which has the advantage of not invalidating your product warranty. Called 200S Boost, it does require a number of prerequisites, including a motherboard equipped with a Z890 chipset and the use of a single XMP-compatible DDR5 memory stick per channel for stability and interference reasons.
Safely overclock your Core Ultra 200K
In concrete terms, the profiles offered by this technology allow you to overclock certain internal frequencies of the Core Ultra 9 285K, Core Ultra 7 265K/KF and Core Ultra 5 245K/KF processors. The “die-to-die” frequency (the frequency interconnecting the different “tiles” – NPU, GPU, CPU – inside the processor) thus jumps from 2.1 GHz to 3.2 GHz, while the “Fabric” frequency (formerly called “Uncore”) goes from 2.6 GHz to 3.2 GHz. The memory controller is also overclocked, the data transfer speed between the processor and the DDR5 memory modules going from 6400 MT/s to 8000 MT/s.
| Processor | Configuration CPU | Frequency Boost P-core | Frequency Boost E-core | PBP |
| Core Ultra 9 285K | 24C/24T (8P+16E) | 5.7 GHz | 4.6 GHz | 125W |
| Core Ultra 7 265K(F) | 20C/20T (8P+12E) | 5.5 GHz | 4.6 GHz | 125W |
| Core Ultra 5 245K(F) | 14C/14T (6P+8E) | 5.0 GHz | 4.6 GHz | 125W |
Enabling this feature, however, requires a BIOS update on your motherboard, and only a few models are currently affected: the ASRock Z890 Taichi and Taichi OCF, the Asus ROG Maximus Z890, the Z890I Aorus Ultra and Master, as well as the Z890 Eagle, the MSI MEG Z890 Ace, and a handful of cards from Maxsun and Colorful. Likewise, only a few memory kits from AData, Corsair, G.Skill, TeamGroup, and V-Color are officially compatible, although there's nothing stopping you from trying this feature with other DDR5 kits in UDIMM or CUDIMM format.
Finally, Intel adds that results may vary and that the stability of the configuration is not guaranteed, as is the case with any overclocking. The 200S Boost feature requires stability tests in all cases (for example, with the manufacturer's XTU software or a Cinebench-type benchmark) to definitively validate the new settings. With the wind at your back, performance gains can reach between 4% and 11% depending on the game, definitions and graphics settings.
