Title: Naomi I base bad ram - help please
Post by: ID4 on November 06, 2019, 11:25:01 am

Hi!

Recently my Naomi base began to show gfx glitches and slow dows, so I did a test ram:

IC20 is Bad, I check de IC20 in board:

The ram chip is "NEC D4516161AG5 A80R 9NF"

I have searched to replace this ram, but only found " NEC D4516161AG5 A10 9NF"

Is this chip compatible? There is another type of chip compatible?  :dunno

Thanks!
