It is of course CPU speed dependent, it's the CPU that is running the test. More over a G3 or G4 upgrade won't help much. While the processor runs at it's higher speed the Backside Cache isn't active until the appropriate extension loads at startup which is after the memory test. Also of course you are limited to the throughput of the computer bus with regards to how fast you can access the memory to test anyways. The part about the cache applies to non-G3/4 native systems, machines that shipped with a G3 or G4 would, I think, have the cache enabled before the memory test. -- Clark Martin Redwood City, CA, USA Macintosh / Internet Consulting [EMAIL PROTECTED] "I'm a designated driver on the Information Super Highway" -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
