I have 4 simm slots and need to which order they go in so my pc will start up. 2 sticks have 2 chips on them and the other 2 have 8. I think they are 72 pin cause the sticks with 2 chips have 1 and 72 on each end where the connectors are. The computer makes a repeative long single beep when I turn it on. It was working fine until I took the ram out to see if it would fit in another computer. It was the wrong kind so I put it back in and I haven't been able to get it working again. Please help me!!!  Did you record the positions the SIMM chips were in when you took them out? You may have ONE in backwards, or they may not have seated properly. Remove and re-install them as appropriate.I do not remember which order they were in. I was thinking about buying new ram maby they are messed up. Would it work if I put new ram in?

B.T.W. I took pics of my computer and the ram if it would help any.trekkie28001.....I think that EDO simm 72pin ram MUST be INSTALLED in pairs......so I would try PUTTING the two sticks with 8chips on each in slot 1 and 2 and the other pair in slots 3 and 4
In fact try just using the 2 with 8 chips and put them in slots 1 and 2 and if it boots up ok shut down and put the other two back in
I just went thru my drawer of misc .bits and pieces and I have a set of 4  - 32mg sticks ....and they will only go in one way.
That should get you working again....

let us know

dl65  It WORKED!!! Thanks!!!! I put the other 2 sticks in at it still did the same thing but then I took them out and left the 2 8 chips in there and it boots up. Now it says CMOS Checksum Error-Defaults Loaded. What does that mean?I fixed the checksum error. I had to adjust the date. It showing it has 16 MB Ram and need to put the other 2 in so I can install 98. It has 95 on it now.trekkie28001......Glad to hear your back up and running.....The other two sticks will make things work a little better........Remember they always must be installed in pairs.......Given what you want to do , I would check with your local computer shops ( repair) and you may be able to find Some 72 pin EDO simm ram at a good price ......( it's an old type ) ideally what you should look for is 4 sticks of 32mg ( I dont know if it was made in 64mg modules.) Your pc is fairly old , but with a ram upgrade it will serve you well.

Cheers,
dl65  CMOS checksum error (Click)I have put both pairs in slot 1 (bank 0) and it works fine but I have tried every COMBINATION of swapping to get Bank 1 to work but it starts up with that beep again. Both simms are 8 mb. Can there be a problem with the 2 slots in bank 1 or  the cmos or bios or something?
