Difference between motherboards

This is probably stupid question, but here goes. What is difference between Slot 1 MB and Slot A MB? Can CPU from one be used on the other? Thanks Jack

A fellow with more knowledge than I revealed to me that the Slot A is/was used for the first AMD K7 CPUs. (You may have seen or heard of Slot A Athlons, for example?) Slot 1 is the form factor for Intel Pentium 2's, Celerons, and Pentium 3's.

I do not believe a CPU designed for an Intel motherboard can be used on the other (AMD) motherboard.

Sorry ... Perhaps someone more knowledgeable will have a different answer ... but I don't think so.

That was what I kind of figured, but thought it wouldn't hurt to ask. Hey you never know sometimes something good might happen with these computers. At least that is what I keep telling myself after over 40 years of working with them. I ran across the AI61 board with the AMD 751 chipset and 700 mhz pretty cheap and thought I would try it in place of my IWILL VD133 board with 400 mhz. Where I am I can't get DSL nor Cable Internet so I try anything I can for little more speed. I am using ISDN 128 which is little faster than dialup 56K.

Again thanks for fast response. Jack

 

Jack, for an "experienced" guy like yourself with "40 years" working with "these things ", some might think, "you have to be pulling their chain ".

 

I really am not. I was in Air Force from 53 till 62 and got most of my experience on the BIG computers. The ones that took up a whole room. That was awhile prior to the PC as we know it now. Worked with IBM 360, 1401s and ended up with the IBM AS400s. Also worked with NCR 315. Programmed all of those, using RPG, COBOL, and FORTRAN. First experience with PCs was with the TI99/4A. Used to run Bulletin Boards before the advent of internet. Those were quite expensive as you strictly paid telephone charges by how long you were on, in minutes, with no local ISPs like there are now. Got onto internet back when it came into being and was entirely different than it is now. I have also installed local Novell Networks, so I have kind of run the gamut. Much better now than 15 and more years ago. But enough ramblings from an old man(69) who is still learning and not afraid to look stupid by the questions I sometimes ask. I am grateful that you youngsters will put up with me. Thanks Jack

 

Jack:

When I saw your question at the top of this thread I thought I had an answer right away. Then I suffered one of those "mental lapses" and for the life of me couldn't think of the answer though I had discussed both since those form factors appeared!

I've only been involved with PC computers "seriously" since '86 when I needed one to run my business. Prior to that I dabbled on a university computer with punch cards, BASIC, FORTRAN, etc. I'm impressed by your wealth of experience. Folks like you are strong in the real understanding of the rudiments of these machines. I'm 47. My best friend is 76 and has been my right arm in building and/or repairing dozens of computers from the board up.

I wrote this to acknowledge how vastly more experienced you are than I.

Brangwen: Well put
jdcobbsr: My hat's off to you - Definately got me beat by a mile and you show the wisdom of knowing there is no such thing as a 'dumb question ".

 

Just to confirm that AMD and Intel motherboards have been separate for a long time now, you have to go back to the days of the AMD K5 and original Pentium to find a "dual" purpose motherboard. I think you'll find ever since the Pentium Pro the two have require different chipsets anyway.

Slot A is for the very first Athlons, I still own one of these at 750Mhz and use it for my Linux Firewall/Router machine, Slot One is for the older Pentium III and Celerons, and I own one of each these too at 733Mhz and 433Mhz.

Slot CPUs went out of fashion when memory became cheap again, the sole advantage of a Slot CPU is that the amount of cache memory can be altered after manufacture as the cache chips are separated on the "daughterboard ", so you can have different cache configurations at different prices, once memory returned to more reasonable rates it was once again incorporated as cache into the main CPU.

You can still get plenty of Slot CPUs and motherboards on eBay, but they don't come cheap, despite being vastly out of date !

Nice to see people with lots of experience, I have nearly 20 years of working in IT with both PCs and larger machines, and over 10 years building my own PCs.

 

I appreciate the info. Makes it a lot clearer. I am running on one of the Slot 1 IWILL boards at 400mhz, couldn't afford one of the 1.? g and had a chance to pick up this MB which has the AMD 751 chipset, with AMD CPU at 700mhz. Know that is not much faster, but anything is improvement. I used to build quite a few PCs over 6 years ago before I had to retire and now I just spend 12-14 hours a day out on the internet. The internet has been real good for us old timers with not much to do. You sure have to be careful though.

I spent four years over in your part of the world, or close to it. I worked for the Army & Air Force exchange service for about 7 years and was in Germany, Munich & Nurenburg from 67 thru 71. Really did enjoy it. Got to travel to Austria, Italy and Switzerland. My youngest son, 33 now, was born in Nurenburg. He is still German and American citizen.

Again thanks for the good info. Jack
