Generally speaking, hardware detection tools such as CPU-Z can accurately identifyprocessormodel, after all, they read CPU Internal identification information displays various specifications such as name, number of cores, clock speed, etc. However, a netizen recently encountered something very rare. He was clearly pretending to be Intel Core Ultra 5 250K Plus, CPU-Z and Windows But they all show that it is the higher-end Core Ultra 7 270K Plus, which makes people feel like they are earning a free upgrade, but in fact this is not the case.

Bought a Core Ultra 5 250K Plus but it was recognized as a Core Ultra 7 270K Plus? Netizen discovered strange bug after changing motherboard
According to foreign media Wccftech According to reports, a netizen shared on the Chinese hardware forum Chiphell that he recently purchased an Intel Core Ultra 5 250K Plus processor. The words “Core Ultra 5 250K Plus” were clearly printed on the box. At first, he used it with a Colorful motherboard. During this period, everything was normal. Both CPU-Z and Windows systems correctly identified the processor model as Core Ultra 5 250K Plus:

However, after he switched to the GIGABYTE B860I AORUS PRO ICE Mini-ITX motherboard, problems arose.
After updating to the latest BIOS version F9, the processor name displayed on CPU-Z turned out to be “Core Ultra 7 270K Plus.” Not only that, but the system information of Windows 11 also showed the same wrong model, and even the BIOS screen itself showed the processor name as 270K Plus. In other words, from the BIOS to the operating system to third-party detection tools, everyone thinks his processor is Core Ultra 7 270K Plus:

However, although the name was misjudged, the actual specifications have not changed. CPU-Z shows that this processor still has 6 P-cores and 12 E-cores, for a total of 18 cores and 18 threads. This is the correct specification of the Core Ultra 5 250K Plus. If it is really Core Ultra 7 270K Plus, the configuration should be 8P + 16E, which is 24 cores and 24 threads. From this point alone, we can confirm that there is no problem with the processor itself, it is simply an error in name recognition:

It is speculated that this problem is caused by the motherboard’s BIOS, not the CPU-Z software or the processor itself.
Generally speaking, when the operating system and hardware detection software identify the CPU model, they will read the processor identification information passed by the motherboard BIOS. If the BIOS itself gets this identification information wrong, then all subsequent software will naturally display the wrong name.

The Arrow Lake Refresh series processors have just been launched not long ago, and the BIOS of some motherboard manufacturers may not fully correspond to the CPU identification database. Such initial small bugs are actually not uncommon and will usually be corrected in subsequent BIOS updates.
If you have recently purchased an Arrow Lake Refresh series processor and encountered incorrect model identification, don’t be too nervous. Make sure the number of cores is normal. If so, there will be no problem. You can update it after the motherboard releases a new BIOS.
