Yesterday I helped a friend set up a new IWill KK266/TBird 1.2G Axia, and the L1 bridges were not cut. For the short term he'll be running it stock clock, but I'm sure in the not too distant future he'll do some o/c experimenting. We also installed a Taisol Cu bottomed HSF. It was my first experience w/ a Taisol and I'm impressed by the heft of that unit, as well as w/ the clip.
