I have a PII 350 Q309 ES that doesn't seem to be fixed. Someone swiped the 450 processor out of a Dell Optiplex GX1p and put this one in it's place. But guess what? This one is running at 450 in that box!!! The Heat sink wasn't even put back on right and was about to fall off and it's running stable. NT reports ~446. I compared it to a true PII350 Optiplex GX1 and Winbench 98/CPUmark32 reported 864 for the GX1 and 1040 for the 350 in the GX1p. Can anyone enlighten me on this processor and what I might expect to get out of it on say a BX6?
