In response to the information that some Quadra family Macs are not able to take full advantage of 64MB SIMMs, Paul Stamsen wrote:

Yes, the 630 family Macs are among those which perform beyond Apple spec, and they are able to fully access 64MB SIMMs. One caution however: If you have installed a PPC upgrade card (Power Card), you will encounter an anomaly. The PPC card does not recognize 64MB SIMMs, and it will revert to a default value of *16MB* (16MB + 4MB on the motherboard = 20MB total). When you switch back to the '040 side of things all 64MB are available, but you are probably better off in this case with the Apple specified max of 32MB, as these SIMMs will be properly recognized on BOTH sides of the processor fence. We hashed this out in the brawling, sprawling, rhyming 'n weaving, early days of the Quadlist -- but I don't generally see anyone now thinking to mention this exception whenever the 64MB Question is asked, so I think it bears repeating. On the other hand, if anyone has SINCE had success using a 64MB SIMM with a PPC upgrade card, please speak up! -------------------------------- On a side thread: Recently on Quadlist, in response to the original question in the thread about using a 64MB SIMM in a C610, someone included this line: "No, 68k Macs do not support Simms bigger than 32MB" In turn, the line was highlighted and resent to the list, and appended with this rejoinder: "This is 100% false." No other comment, only "...100% false" -- I wrote back to say that I thought the _first_ post was more relevant to the question asked. At worst it was only imprecise, not "100% false". I suggested that it could be corrected easily to read: "No, _this_ 68K Mac (as is the case with most others) does not support SIMMs bigger than 32MB" Which was followed today by this response: "Which is what was said in the first place when the question was answered two days ago." ******* I ask your forbearance in recapping all the above; I only do this by way of suggesting that sometimes more experienced members of the list may mislead less experienced readers by engaging in snappy rejoinders, such that might be appropriate and enjoyable in a smaller, more 'clubby' atmosphere where everyone knows one another and shares similar status. Although the first response was imprecise (flatly stating that 68k Macs do not access larger SIMMs rather than noting only that _most_ do not), it was closer to answering the _real_ question asked. To say that the answer was "100% false" is hyperbole, and I DO understand the attraction of hyperbole among the tech savvy. But I felt that the rejoinder was more misleading to a newcomer than the original (albeit, imprecise) statement. I don't mean to chide in any way. But part of the charm of the Quadlist is the rough and tumble mix of experienced and inexperienced people sharing a run-on conversation about our much loved '040s. A friendly but salty putdown, all in good fun, *among friends*, can refresh us all (and whatever did happen to the Serker, Scott Barber?). But it requires a light touch. I urge the more experienced people on the list to ask themselves first whether they just _might_ be, in the end, more indulgent and misleading than helpful when snapping an irresitable slap shot. Even if it CAN, oftimes, be fun (at least for one). -- Quadlist is sponsored by <http://lowendmac.com/> and...
