Carmine,
The +33 mhz ram speed is availible on 100MHz FSB setting only. If you want to know if the Iwill can take your cpu to the max, the answer is yes. If there is a limitation, it would be related to your other components, like ram or video card, etc. My Iwill is a revision 1.1 and most reviews on this motherboard was also ver 1.1. At 160MHz FSB is very likely acheiveable without active cooling fan. I tried putting thermal paste under the northbridge heatsink and I was able to go up to 165MHz FSB but that needs some really good ram and I wonldn't feel comfortable running a pci bus speed of 42MHz anyway. What I'm trying to say is that you won't be disappointed. I'm also glad it got a good 4.1 onboard sound while I have my sb live fix. Read all the reviews on Iwillusa.com and decide If you want to give Iwill a try.
