I need help with RAM upgrade on Sega Naomi

[daytonausa]

I've recently upgraded the ram in my DIMM to 512mb. It doesn't boot, just black screen. Stock 256mb is fine.

Not sure if I used the wrong ram or if it's just defective (the guy did ship off the ram in a box missing a side that was packing taped sealed, so you never know).

Does anyone know the specs needed?

Thank you so much. This really helps.

Dumb q but does it matter which slot if I get a single dimm? Ordered a compatible 512mb stick.

It always matter which slot you put it in, ask your mom…

I bought it from this listing, and it's a crapshoot if you get ecc/non-ecc or even working ram.

The two I bought were fine, but it’s an easy enough return, right?
