This is not an official ASUS BIOS, only enables base clock overclocking on non-K CPUs. Don’t use this for K-series CPUs. It might damage your hardware, no guarantees provided.

Issues found so far

  • No IGPU
  • No dynamic change of CPU frequency
  • No C-states
  • No Turbo Mode
  • CPU temperature reading is incorrect
  • AVX instructions have very low performance
  • Windows XP ACPI not supported


After flashing set the following settings to make it boot into OS with correct CPU speed

Advanced\CPU Configuration
- Boot Performance Mode -> Turbo Performance

Advanced\CPU Configuration\CPU Power Management Configuration
- Intel(R) SpeedStep(tm) -> Disabled
- CPU C states -> Disabled

I don't have an ETA on the BIOS for that specific model yet. When the BIOS is in my possession, I'll post it here.

Are you having problems entering Windows with a stock system or with an overclocked system? If your system is overclocked, your overclock might be unstable. You'd need to tweak it some more.

hi
first i update my bios to non-K BIOS and continue your Instructions for non-k oc. But then I saw this problem(windows dont boot and
stuck at Windows startup).
after that i tried to flash and update non-k bios to official bios and default bios. with official bios windosw stat correctly.
again i update bios to non-k version… and dont Change bios settings….But without the change bios setting , Windows can not boot and stuck at Windows startup !

my problem is non-k bios ...with a stock system or with an overclocked system or diffrent Instructions ,my windows can not start
