Hey to all wannabe extreme clockers.
This thread is here to help you understand post codes and how to 'avoid' them.

00 Bclock Usually it is appeared when you use high bclock. So, try a lower value
01 Motherboard Usually it means nothing when it comes to oc. It is just

00.|Bclock|Usually it is appeared when you use high bclock. So, try a lower value
23.|IMC|Usually it means that IMC can't run on the specific memory frequency. So, try to use a lower divider
55.|IMC or RAM|Usually it is appeared when you use high memory frequency, tight timings or both. So, try a to loosen timings or lower memory frequency
FF.|CBB|Usually it is appeared when you xtreme cooling. Most of the time it means Cold Boot Bug. Try to warm up your pot (or cooling method :p )
A9.|Incorrect Settings| A9. based on my tests seems to be a result of high overclock. So, try more realistic settings :D

Important TIP:
If you see new, unusual and strange Post Code errors, check for insulation problems on our system.
Humidity can cause liquefaction at low temperatures

Hmm... for all my 3 gigabyte boards in my past 5 university years "FF" actually indicates that everything works. In fact the booklet that comes with the mobo says FF represents "Fine Function".

[00] Means it has booted operating system (Normal Operation) according to booklet provided with the motherboard.

Simply this post codes mean different things on different motherboards, though I might be wrong.

Yeap thats obvious :p

Just for the record the above post errors are the most common errors you may get under xtreme cooling on Evga, Asus and Asrock Z77 boards.
Don't know if they have the same emaning when it comes to other vendors with same chipset or same vendors with different chipset (asus z68 for example). :)

Maybe you should post which motherboard these codes belong too since most some boards have different codes for different errors.
