I have been rebuilding the OS on an old system that belongs to a relative. While I was at it, I decided to put in some extra RAM I had sitting around.
The motherboard is an unidentified model, I have no way of knowing what it is, as I can't see an fcc id, or any other markings. The board has 4x simm slots, and 2x dimm slots. I have added 2x16MB simms, and I also have a 64MB dimm, which I have slotted in there.

The question I have is this:
Has anyone else ever found dimm (or simm for that matter) slots to be ridiculously tight?
I had to push VERY hard to get the dimm into the slot. So hard in fact, that I was worried I might crack the motherboard, even though I had it well supported.

BTW, they are definitely the right type - I have the motherboard manual (which doesn't identify the make or model, but does list what all the slots etc. on the board are)
