I recently upgraded to a KT7A-RAID and a 1gig TBird. I decided to mod my Alpha PEP66 that was on my old PIII to work on the new rig. Now, the Alpha I have has the slightly raised copper inlay where the core is SUPPOSED to contact the heatsink. I performed the mod on the shroud so the fan is blowing straight down at the chip, clamped it in and proceeded to run the Tbird at 1133 (8.5 X 133), which I was a bit disappointed with. I forgot to mention that I chipped a corner off of the core while trying to get the Alpha on, and I thought I was hosed before I even fired it up for its maiden voyage. What was strange was that my temps under load with the PEP66 were in the high 50s. A week later, I decided I was going to lap the PEP66 and put it back on. When I removed the HS, to my surprise and horror, I realized that I had the HS turned 180 degrees from the way I wanted to attach it originally. This meant that the raised section of the HS that was supposed to contact the core ended half-way across the core!!! For the entire week, only half of the core was contacting the HS, and the thing managed to still run overclocked. To make a long story short, lapping the Alpha didn't help, and another chipped corner later I decided to use the HS/fan combo that MWave sent with the bundle (a cheap Taisol I believe) and surprisingly, I can run the chip stably at 1120 (8X140) at 1.675 volts and the thing rarely goes over 45C. Unfortunately, I think if I had my head out of my ass in the first place I would be running well over 1.2GHz since the chip is a week 3 2001 chip. Oh well, live and learn.
