re i don t understand si mg joohwee students neural iss nus sg wrote mg i went buying simms recently and the sales person told me that the mg are chip simms and chip simms and one cannot use them interchan mg if you use one you have to use all of the same type don t believe everything you are told i can tell you that mixing them between banks ok and i can t see why mixing in one bank is not unless they are of different speeds e g mixing of ns and ns simms in one bank the two only differ in the type of chips it uses assuming that the simms are mx bit wide here is the two equivalent configuration the chip simm uses two bit wide mbit m of bit nibbles and one bit wide mbit chip for a total of bit wide mbyte the bit simm uses nine bit wide mbit chips these are equivalent because of the way that it is pinned on the simm board at the simm interface they both act as bit wide mbyte simms sorry if too techie for ya mg similarly one cannot plug in two mb simms and one mb simms to gi mg the system a total of meg why is that so if my system supports mg of meg it has simm slots can i plug in mb simms to give my mg mb that sounds correct the problem is that if your computer takes bit wide simms you can not mix different sizes in one bank why you ask simple if you understand why there is banks assuming you have a bit cpu dx or the data bus e g the mechanism to retrieve data from memory is bits wide so the computer expects to see bits when it asks for data to get that bandwidth bit wide the motherboard links mx one bit is not data but parity so i will ignore that in this simple explaination to get bits bits that means that a simm in a bank stores only of the bit wide data if you have a bit bus two mx simms are linked together to get bit wide data which is the reason why banks are simms wide and bit banks are simms wide if your computer required mx e g bit wide data with parity bits used in some ps s and asts you could upgrade by one simm at a time hope that this message is not over your head but the answer to your question was not simple i could of just said because i said so rdd winqwk b unregistered evaluation copy kmail d w net hq hal k ann arbor mi us or hal bbs qwk to usenet gateway four v bis dial ins free usenet mail and newsgroups pcboard am uupcb kmail call or member of eff asp asad mb disk serving ann arbor since
