32 to 96 MB
I wanted to expand my memory, from 32 to 96 MB by placing two 32MB edo simms on my Asus P55T2P4, but the system or windows doesn't recognize it. It seems to see the 2 32 MB chips as an 16 MB chip. ( it shows only 64 MB with 2x16 MB and 2x 32 MB and when I take out the two 16 MB simms it only counts 32 MB)
Is windows 95 (4.00.950a) causing me this "lost" memory ?

No, Windows 95 is not losing the memory. What is happening is that your motherboard is not configured for the type of RAM that you have installed. Check with the manufacturer of your motherboard and see what the proper configuration is. You may have to purchase a BIOS upgrade from the manufacturer to fix the problem.

On the asus site i could not find an answer. In the handbook is stated that I can use EDO or FPM 70 or 60 ns chips,of 4, 8, 16 32 or 64 MB Both the simm sets i use are 60 ns- edo SIMMs,
the 16 MB with 8 chips, the 32 with 16 chips could this be the problem ?

No, the number of chips on your SIMMs is really rather irrelevent to your problem. These are just different manufacturers' physical configurations.
3 possibilities:
1 of the 32M simms is bad.
The simms are not 2x32M but 2x16M.
Make sure that the new sims are seated in slot 1 and 2.

I get the same readings placed in bank 0 ( slot 1&2) or bank 1 ( slot 3/4) When I take out either one of the 32 simms the computer won't startup, it just gives a bieb, so how can i test one is faulty, ?
They must be installed in pairs. Try using only the two new simms together in each bank with nothing in the other.

Also, some MB's require ALL simms to be the same size or only specific combinations of sizes so even though you have a list of several sizes, see if you can find out what the acceptable mix is for your system.

bchew 1: I did , with the result reading only 32 MB
bchew2: The handbook reads: "Install memory in any or all banks in any combination as follows:
bank 0 simm slots 1/2
4 ,8,16,32,64 MB FPM or EDO Simm x2"

Combine a new one with an old one (16 + 32). Does your computer come up now?

It stops/freezes at 640K now
The bios is quit old: Award 9/02/96 could this be the problem ?
