AI enabled running Windows on an incompatible combination of the Intel Bartlett Lake processor and a Z790 motherboard

How a generative AI helped an enthusiast run Windows on an incompatible motherboard

Generative artificial‑intelligence models have opened new possibilities for computer hacking enthusiasts: you can now “write” microcode for motherboards even when official documentation is unavailable. In this context, a member of the Overclock.net forum under the pseudonym Kryptonfly managed to get an Intel Bartlett Lake processor (the 10‑core P‑core family) running on a motherboard with a Z790 chipset, even though such a combination is not officially supported.

What was done
1. First success – Kryptonfly got Bartlett Lake to pass the initial BIOS boot stages.

2. Further work – he focused on modifying the firmware of the Asus Z790‑AYW OC Wi‑Fi, using prompts from Anthropic Claude’s chatbot to bypass restrictions and launch Windows.

Main difficulties
- Memory initialization. The BIOS did not recognize Bartlett Lake as a compatible processor.

- Solution: make the firmware “think” that the system has a Raptor Lake, after which Windows boot became possible.

- Nevertheless, with Bartlett Lake installed the user still cannot access the real BIOS; this is only possible after replacing the CPU with a fully compatible one.

Future plans
Kryptonfly intends to continue working on microcode for other LGA‑1700 boards, including Asus Apex and Encore models. The goal is to make Bartlett Lake suitable for a wide range of consumer motherboards.

Why Bartlett Lake is so interesting
- 10–12 P‑cores without the budget E‑cores provide significant performance.

- Compared with typical Core models that are usually limited to 8 P‑cores, Bartlett Lake can show an advantage in multithreaded tasks (e.g., Core 9 273QPE and Core 7 253QPE).

- Therefore, enthusiasts’ efforts to “bind” these processors to consumer boards have a logical basis: they unlock high performance without needing to buy expensive server solutions.
