I'm starting on a new review (still need to receive two sticks of DDR400 memory though) of the AOpen AX4SG Max Motherboard. Today I checked the AOpen site and I noticed there was a new bios update with release date 2003/06/17 :
FSB 800MHz CPU and Corsair DDR 400 CL=2 Memory Module compatibility issue.
Updated EasyFlash/DieHard BIOS Lite R2.02
USB keyboard support item default by Auto and remove Enabled.
Added "Performance Boost Engine" (PBE) item in Chipset Feature Page,to improve performance and default value is "Disabled". This PBE function is similar to Intel PAT function
After Asus and Abit, AOpen is now also doing a 'PAT' comparable performance improvement on one of their Sprindale motherboards! AOpen calls it PBE or Performance Boosting Engine. Rumours go out that all Springdale and Canterwood chipsets have the Intel Performance Acceleration Technology. Even more suprising, some are claiming that PAT is even standard activated on the Springdale if you are not using a 800MHz FSB CPU. Asus, Abit and now even AOpen have released a new BIOS for their Sprindale motherboards, this new BIOS activates the Intel Performance Acceleration Technology by making the chipset think you are using a 533MHz FSB CPU..
