RAM-ing speed! Re: Where to get RAM?
--- Amber Rhea [EMAIL PROTECTED] wrote: I've often wondered what would happen if one tried SLOWER SIMMs that those listed as the minimum requirement. Everymac.com has various Macs noted as requiring 80ns, 70ns, 60ns, et al. My curiosity hasn't been so burning that I've bought slower SIMMs for this purpose and tried them in a Mac, but it would be interesting to know why this SIMM speed requirement is important, and why it varies so from Mac to Mac, even among Macs made around the same time. On the RAM bus, the memory controller sets the timing of reads and writes. When the bus is set for a read or write, it waits a certain amount of time for the RAM to be ready to read or write. If you use too slow of RAM it won't be ready to be read or written before the time for the operation to take place ends. Then you get a memory error and bad stuff happens. To some extent older computers can be sped up by using faster RAM than the slowest specified. The reason is that a computer that requires at least 80ns RAM will read or write data the very instant the RAM is ready. Older systems generally used a longer window of time for RAM operations to take place. Popping 60ns RAM into a system specced for 100ns will allow most memory operations to take place right at the start of the time window, thus giving a mild speedup. 10-15 years ago when I was using 8088/80286/80386 PCs it was quite easy to see the speed difference when I upgraded a box to 60ns or 70ns RAM. The RAM test part of bootup would fly by with a BTTT! instead of me being able to hear a distinct tick for each K. Of course, loading up a 286 with 12megs of those individual 256Kx1 DIP chips was horrendously expensive and used up three of the ISA expansion slots. What was funny was I didn't have all the RAM the same speed and the memory test sounded like it was shifting gears as it went from the faster RAM to the slower chips. (I configured the 60ns stuff as conventional and XMS and the 70ns as hardware EMS so the 70ns wouldn't slow down the faster RAM.) If you take a IIci and install 70ns SIMMs in one bank and 60ns in the other, it will all run at 70ns. The same goes for PCs, except for the olden days of memory cards on the ISA bus. As computers got faster, the slight speed difference from using faster RAM became imperceptible to the user, and only a benchmarking program could tell the difference, which in normal operation doesn't amount to a hill of beans. :) The memory timing cycles are so tight now that even a couple of nanoseconds too slow will cause trouble, which is why it pays to buy name brand RAM like PNY, Micron etc. = The earth swarms with inhabitants.

Re: Where to get RAM?
As a side note, I've found that RAM that is on the line as far as speed - May work, and pass tests when it is cold but will get worse as it warms up. I had two 60ns SIMMs in a 8100 that did just that.

Where to get Ram
I bought four 16 mg 30 pin simms from Macsolutions.com about two years ago and they are functioning perfectly in my Quadra 700. They were inexpensive for the date, too. I think I paid $17.95 a stick. They got them to me one day earlier than promised as well. I have no affiliation with them, and that has been my only purchase from them. All the best, R. A.

Re: Where to get RAM?
In a nutshell, either the RAM will work faster than its rated speed, or you will start to get random errors on your Mac. For comparison, try checking around PC forums and see how people overclock their RAM. Today its no big deal, but back in those Mac's era, RAM didn't really overclcok more than 10ns, unless you were lucky.

Putting 120ns RAM in a IIci is like putting PC100 in a new G4. FYI PC66 will take 83MHz usually, PC100 up to 112 or so. Never overclocked PC133. RAM speeds are just like CPU speeds in that they can only go so fast. They get hot and have limits (beyond heat). Peace Aqua -- Vintage Macs is sponsored by http://lowendmac.com/ and...
