Just a few questions about SDRAM after reading the FAQ. (I am interested in memory at the moment, so I read it, even if no-else will).
What is the 16Mx8 and 32Mx4 organisation? I don't understand this. I understand as far as 8 chip being single sided and 16 chip being double sided, and that, for example, the 440BX chipset supports 128Mbit chips meaning that I can install a max. 256MB sized module if I use a double sided (16 chip module) (which I have sucessfully done on a couple of occassions). However I don't understand 16Mx8 and 32Mx4 and where that comes into it. If this could be further explained I would greatly appreciate it.
Also, if I were to accidentally install, for example, a PC66 memory module on a 440BX board running a PII 400MHz processor, which would require PC100, could I damage the processor?
And, does anyone know of any visual way, by physically looking at a memory stick, to tell whether it is PC66, PC100 or PC133, assuming that there is no sticker. Otherwise, what would also be very helpful if someone knows of a program that could be downloaded which would check and report on the modules installed to say whether they are PC66, PC100 or PC133.
Finally, I don't understand the concept of caching RAM. Does this mean that everything in RAM has to be stored again in some kind of faster memory store, or what?
Any information from anyone on these general questions I would really appreciate. Thanks.
