Power Macintosh 9600 ram modules question

Hey đź‘‹
question for you all guys : I have a 9600/350 in restoration process which needs ram modules.
I was searching 128MB edo ram dimm 168 pin to have it full expanded ; however, I found (at a good price) 256mb modules of the same type.
Do someone here know if I can install them and simply see the maximum amount of ram the system can accept (1536Mb) or the bigger modules can cause other type of problems?
Thanksss

I believe the max RAM will still be limited to 1.5GB in Mac OS 9 if I understand what I've read before. But...

I have seen a 256MB SIMM being used in a mac before. I was really intrigued, sadly @ThisDoesNotCompute didn't notice, or at least comment that he had such unusual RAM SIMMs in his Genisis ;)

It opens interesting possibilities for something like an 8600, or a 7200, if you could find a low profile 256MB 5V SIMM.

Is the SIMM you're looking at low enough to clear the outrigger bit of the 9600?

The party is already gone ; even if the modules are compatible, they don't fit in the 9600 (too large).

Interesting about the 256 MB modules in a Genesis, as a careful reading of the PCI Power Macintosh Hardware Developer Note and what memory chip addressing schemes are supported will lead to the conclusion that 128 MB per DIMM is the maximum supported.

The 7200 on the other hand, clearly supports up to 256 MB DIMMs (according to the HDN), but I've never seen one.

Hmmmm.

Either I read them wrong, or the HDN for the 9500 is incomplete/incorrect, or that Genesis wasn't what it seemed.
