Test the status of D4564323G5-A10-9JH chips ?

[chacal231077]

Hi!

I would like to know if we can test the status of chips D4564323G5-A10-9JH with an eprom programmer ?


I have a Naomi Black Screen motherboard.

I don't know what chips are located for this problem ?

Apparently they are in pairs when they malfunction

I have several new chips but I would just like to change the good ones and not waste new ones in a vacuum

I'm going to desolder them all with the Chip Quik SMD Removal Kit so as not to shoot them too much at the hot air station


So basically there is a test bench with an adapter on eprom programmer for his little bugs


Thanks

i dont know of anything that tests that ram
i suppose you could build something from a nucleo-64/144 or some other dev board that runs at 3.3v and has a lot of I/O pins
most people just swap them and if it works the ram was bad.
they dont fail in pairs btw - they are used in pairs.

if it's black-screen though, check the fan(s) and check for 3.3v at the main chips.
the board monitors the tacho pin from the fan - if it's not pulsing it wont power up the main chips - so they dont burn.
