I've had problems with my G3 upgrade in my 7600 ever since I bought two sticks of 128MB. I've actually had similar problems with my mom's 6400, although hers has no upgrade. I finally figured out the problem when I stumbled upon the 2k refresh requirement for the 6400. Ends up the sticks are 4k. And 3.3V for that matter (no linear regulators), I don't know how they actually work at all, but they do. Barely.
Unfortunately the problems with my 128MB sticks is more difficult. OWC says that certain sticks aren't compatible with G3 upgrades in a 7600. I believe it does 8k refresh natively and for everything else it does translation, which doesn't work correctly with an upgrade installed. Correct so far? The problem is that the 128MB sticks seem to have had the markings removed, and some other markings added. There is not even a manufacturer's mark. All I get is: 8X8E43VTW. Normally I just punch those numbers into Google and something will pop up. Actually I will go to the manufacturer's site first and look for some specs, but if I can't find it, I just Google it. It ALWAYS comes up with something. Except this time. I get nothing on those numbers. Not horribly suprising since it seems like the real markings were removed. I don't think FPM/EDO sticks ever had SPD chips on them, or I could just dump the contents of that. I believe that is a SDRAM thing, though. So how do I find out what the refresh is? There has to be an app somewhere that can tell what the addressing (is that the right word?) mode is. _________________________________________________________________ Add photos to your messages with MSN 8.
