GIGABYTE support reportedly points to BIOS fix for 250K Plus shown as 270K Plus

A Chiphell user claims his boxed Intel Core Ultra 5 250K Plus is being identified as a Core Ultra 7 270K Plus after switching to a GIGABYTE B860I AORUS PRO ICE motherboard. According to the post, the system BIOS, Windows, and hardware monitoring tools all report the CPU as 270K Plus, even though the processor was purchased as a retail 250K Plus.
The user also says the CPU box carries a 250K Plus label, and later adds that the markings on the CPU heatspreader itself also show 250K. That lowers the chance of a simple packaging mix-up. The same thread says the issue was not noticed earlier on a Colorful motherboard, although the user did not provide screenshots from that system.
Wrong name, correct specs
The user reports that CPU-Z still shows an 18-core configuration , which matches Intel’s official specification for the Core Ultra 5 250K Plus. Intel lists the Core Ultra 7 270K Plus as a 24-core part, so this does not look like a real 270K Plus hidden under a 250K Plus label.

At this point, the most likely explanation is a BIOS or microcode identification bug rather than a mislabeled CPU. That lines up with the latest update from the thread, where the user says GIGABYTE support told him to wait for a BIOS update. GIGABYTE’s product pages for the B860I AORUS PRO ICE also state support for Intel Core Ultra processors and recommend using the latest BIOS.

If we were to guess, this may be related to the late changes Intel made to the 200S Plus SKU plans. As we know, Intel cancelled 290K Plus, and we are quite certain such SKUs had to be rebadged at some point. Perhaps during this process other processors were also affected by CPUIDs misconfiguration.
