All right, have some Schmitt buffers left from previous projects, will try this out, just need to figure out where can i cut that track...🤔

Any firmware feedback? I also increased the refresh frequency on this build to see if it helps some of the more sulky rams.

I only have the Micron MT48LC16M16A2 RAM, but flashed it and it is working fine on the 1d4 and 2B :)

For me it works fine on MT48LC16M16A2-6A but as if the card was slightly slower. Unfortunately, I do not have other types of memory at home yet to test more.

I no have memory for 128mb so I not check this

No difference for me - same as before. But I don’t have any of the non-working motherboards.

I done update but have 64mb Fast Ram
All working good

Working fine for me! If I wanted to swap 64MB chips for 128MB chips - what's best to go with?
