I don't think anyone made cache chips faster than 250Mhz. When I had a 300 Mhz G3 with a 200 Mhz cache, it ran fine at a 3:2 ratio. IIRC, there was an early G3 clocked at 250Mhz with a 250Mhz cache also, so running at 1:1 works. The limitation is that the cache chips must be rated for the speed you are asking for. -- -- Mr. PopMan - [EMAIL PROTECTED] - "Does anybody want to play a game of pinball?" . . . this thing we call 'failure' is not falling down, but the staying down." --Mary Pickford -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
