128MB 5V DIMMs in Power Mac 7300

Is anyone running 128MB 5V DIMMs in their Power Mac?

I've tried some in mine, but they don't work. 64MB and lower ones work fine.

There is mixed info on the web, whether they can take 128MB or 64MB is the max.

I've run 128 meg DIMMs in many PCI Macs including a 7300 with 1 gig and a 9600 with 1.5 gigs for many years. No problems, so long as you get the right DIMMs. Mine were from Other World Computing, so they're correct and have a lifetime warranty.

Maybe there is some other difference on the DIMM.  I've used 128mb DIMMs on many PowerMacs without issue.

Thank you. Must be the RAM. I tried it on a 8550 motherboard I have (and in a Power Mac 8200) and it does the same.

I have successfully run 128Mb DIMMs in my PM9600 for years, and also successfully used them in the 7300/7500/7600 machines and I beleive they worked in my PM5500 also. that covers most of the major board architectures that use 5V 168 pin DIMM's.
