What a journey the last few weeks has been. I bought a PowerLogix Z-Force and 350MHz/1MB ZIF from seperate sellers on eBay several weeks ago, as well as a new Acard Ahard "Big Claw" AEC-6260M ATA-66 PCI card.
All of this was installed in a 7500. Bad trouble upon shutdown/restart but never when just rebooted. Specifically, DFA would run even though I had shut down OK. Fast forward a few weeks and a 266 DT lands in my lap, so everything but of course the ZIF carrier goes now into the G3. Similar problems happened again, but all along I'm cursing the IDE card since most of the bad mojo appears to be happening mainly to whatever HD is attached to it. Disk Warrior revealed bad BTree catalogs or damaged volume wrappers, (sounds like spoiled food wrappers...) and could fix them until I shut down again. Ditched the IDE card, still problems. Ditched the new G3, problems gone. Thinking I was overclocking the new G3 too much (seemed fine up to 433MHz, stock bus and PCI speeds), I even ran it below 350 and it never helped. Since the damage only occured during shutdown I was thinking: bad RAM (it's new, from OWC) but given all my testing I'm certain the CPU is bad. Everthing's great until I swap that in. I'm ready to chalk my $45 purchase up to experience, but I'm wondering if anyone else has experinced a faulty CPU such as this? Part Two: Given that I'm back in 266/512-Land (sigh, miss that 1MB of L2) I've begun experimenting with overclocking it. Since the Mac has all three PCI slots used I'm not interested much in pushing my luck with anything other that the stock 33MHz PCI bus, which leaves the following top two choices this particular CPU can run: 300MHz @ stock bus/PCI speeds or "first generation PowerBook Wallstreet mode", i.e. 292MHz, 83Mhz bus Both work, although I recognize that 83MHz has been reported as iffy. Any long-term consequenses or known serial port issues with either choice? -David -- G-List is sponsored by <http://lowendmac.com/> and...
