Memory for Indy - toncho11 - 09-30-2023

Hi,

I am searching for memory for my Indy.
Does the memory needs to be identical sticks?
Can you use both EDO and FPM in Indy? EDO looks to be compatible with FPM - subset.
I found a guy selling 2 x 16MB Nanya and 2 x 16MB LGS for a total of 64 MB. Would it work? I plan to install Irix 5.3.

No, you cannot use EDO memory in an Indy. EDO is not "upwards compatible": it uses different RAS timings.
You need true parity FPM (fast page mode) 72-pin SIMMs with a 36-bit organization. The maximum SIMM size supported is 32 MB, for a total max memory size of 256 MB.
I would be surprised if Nanya ever made suitable RAM: the kind you need was made before 2000. Kingston and MemoryX may have suitable memory today.
I would also recommend finding a set of 4 SIMMs identical and made from the same chips (manufacturer and product codes) since they are accessed in groups of 4.

Does the Indy require parity FPM or it is just recommended?

Parity is required.
