I have updated to version 1305 which is the latest BIOS listed according to http://wiki.p5wdh.de/doku.php?id=downloads:bios but I find it may have some bugs. In trying to get some higher stable speeds, sometimes the system according to speedfan and other programs just shows one Core. But with the original BIOS 1001 that my mobo came with I had no such problems.
Here is the list of BIOS in order of appearance as per above site mentioned:
even the order above doesnt make sense but anyhow thats how they are listed. I am interested to find out what others are using. PLEASE LIST
I'll answer my own question. 1305 and 1401 are teh best and latest BIOS, they enable higher FSB up to 550 and more temperature intervals, better SPD timings on auto so you dont have to mess around with timings if you are a novice like myself.
I hope that information helped me . Thank you to me .
