here is some update.

i just got smile mac with nomal bong sound.

i had replaced the 10 ram and 1 74s244.

but actually 74s244 was not problem.

the problem was just ram only. more than 3ram was unnomal.

thanks for everyone's help.

have a good day!!

Congrats on the fix.

change the rest,   i personally do not like sockets.  if you do the ram right once its done, no need for sockets.

they cause more issue then good.

yep. socket make some issue actually.

ram was not just fit with socket, and sometimes i had to push the ram.

i will remove it all some day.
