EDO in a pentium?
4 72pin slots?
installed in pairs?
tried installing only the 16, to see if it is recognized?

You have to install the memory boards in pairs, not one at the time. You will end up with either two boards in or four boards in. Won't work with one or three. You need another one

30 or 72 pin simm's generally have to be in pairs.
The data bus has to have a full "width" to function.
30 pin simm's are 8 bits wide and the data bus is 16 bits.(need two)
72 pin simm's are 32 bits wide with a 64 bit data bus for pentium(need two) (32 bit data bus for 486--need one)
168 pin simm's are 64 bits wide with a 64 bit data bus(need one)

Pull the original RAM, and insert the new one.  What does the motherboard detect?

Do you have a "recent" motherboard, or something old, like, say, Intel 430VX ?

Also very few boards can use both types, Dimm and Simm at the same time. So if you are mixing them it won't use it. Since you haven't responded to any of the comments   are you still interested. You can accept an answer and award the points, reject all answers and save your points, ask for more information or delete the question and close the debate.

can't delete since an answer has been proposed (without going to the big cheeses up stairs and requesting a delete)

If you don't think we have answered your question reject the proposed answer and then you can accept any comment as an answer or delete the question

Rather than "deleting" the question, you should select the E-E "expert" who helped you the most, and then award the answer-points to that expert.

Receiving advice of expert(s), and then deleting the question, is very frustrating, and unrewarding, for those experts who have contributed; please don't do this.

Yeah but you need to reject the proposed answer I gave because it addresses Simms not Dimms as you reposted you had. Pulling them out and putting them in one slot at a time will give you more detail. Take out both, put one in one slot, reboot and see what it gives. Take it out and put it in the other slot. Repeat that with each stick in each slot and you will determine if you have good slots and good sticks. But still reject the proposed answer and either pick a comment as an answer or delete the question and the next time you have a question, use a different name cause we'll remember...LOL  just kidding on that last part
