During the standard flash process (Erase → Program → Verify), the step is the final check. After the programmer writes your BIOS or firmware file (the "buffer" data) to the memory chip, it reads the chip's contents back and compares them byte-for-byte with the original file.

Based on countless community reports, the "contents are in disagreement" error is almost never due to a single, complex hardware failure. Instead, it is most often caused by one of the following issues: During the standard flash process (Erase → Program

, is a common reason the chip can be read but not successfully written to. Insufficient Power Instead, it is most often caused by one

The CH341A powers the chip from USB (500mA max). Weak USB ports (e.g., front panel ports on a PC) cause brownouts during write cycles. Use a powered USB hub or connect to a rear motherboard USB port. Some users add an external 3.3V supply (e.g., from an AMS1117 regulator) to the chip’s VCC pin. Use a powered USB hub or connect to
