Woohoo! I think It's working! I think I have a 2.26ghz CPU in my 9300! Prime95 has been running without errors for almost 5 minutes and the CPU is right at 60C.
The key is to ground vid3 (put a wire that bridges G3 and H3). Yah, I know I SAID I tried that and it failed. The problem was that I forgot to twist the lock mechanism on the CPU socket this last time. So the system shut itself down to prevent damage. I noticed it was unlocked when I took the system apart to put the old PM1.6 back in. So I thought... "Well, Im pretty good and taking this thing apart and putting it back together... Let's try it one more time... "
BOOYAH! I have the fastest 9300/XPS2 in existance at this moment! I am Dah Man!
P.S. Im typing on the 9300 while prime95 is running. The CPU has dropped to 57C. Prime95 has just passed test 1300.
