Seating Ram Chips
I'm having trouble with seating the RAM in a 450 mhz Pent II. It's been an on going problem. I've had the problem with one 128k Ram chip, I exchanged that one for another and still had the problem. I upgraded to one 256k chip and still get the beep. Not all of the time but usually once or more a day. The computer then locks up. The beeps go from one occasional to what sounds like an English Police Siren, dee doo, dee doo. You also get one of the beeps during the boot up process. Any ideas would be helpful. Are there any adhesives or maybe something like a "hold down" to seal the chip in the slot?
The DIMMs are VERYYYY difficult to lock in until you get the hang of it. Those notchs have to be in the clips. You have to use a moderate amount of force to lock them in, but not too much. Once they are seated in, they should never just pop out
You aren't using gold contact ram in a board with silver on the sockets are you? Dissimilar metals corrode very quickly and can cause the problem you are describing. Taking it out and re seating it scrapes the corrosion away....
Are you using PC100 SDRAM?
And I'm also assuming that you meant MB when you said k, or something is definately wrong!
Don't use any adhesive on the DIMMs! It will most certainly ruin them!
If your dimm slots have the locking levers, make sure they're engaging into the notches in the dimm. Not all levers lock in, and not all dimms have notches. Some have two notches for different size levers. Sounds like you've got mismatch.
Absolutely NO adhesives!!!
Had the same problem with my PII/ATX/Intel MB.Took it to the shop and the tech rep laid the case on its side to get enough "push" to seat the ram in the slots.He said this was normal for Intel MB's.
I've had to put some foam behind a motherboard or two for temporary support while inserting ram. Make sure you remove it afterwards. Seems to me this was on a flimsy PCChips mobo.
