Summary: First of all, you got to upgrade the BIOS of your P5B, if you have one. Our board came with 0211 BIOS and we achieved very low performance results with it. This was solved by upgrading the BIOS to the latest version available on the day we tested this board, which was the 0904 version. For you to have an idea of the problem, performance increased by almost 20% on PCMark05 and 15% on Quake 4 with this BIOS upgrade. This is amazing.
La nueva bestia de Intel al límite: Core 2 Duo + ASUS P5B Overclocked
