okay, got my AS3 on, and everything set up, it's restoring windows XP now. The first thing I noticed when I turned it on was it was QUIET. Even with my case open, it's not all that loud (I used to have a slot-A Athlon 800 w/ 2 CPU fans). It's running stock now, I just upped the mem timings. I'll take it up to 133 after windows is up.
My southbridge also says this:
SiS 961
PLA 5544
0150 EA A2 (the A2 is in small letters)
Does this mean it's the A2 revision of the 645 chipset? I thought I saw somewhere there was an A2 revision that was better. Anyone know anything about this? I tried taking the HS off the Northbridge but that damn thing was on there good, I didn't want to break the plastic pins (or the motherboard).
