DE10-Nano not detecting RAM. Any way to fix?

Unread post by hrechkaness »

Looks like my De10-nano is broke, it doesn't detect RAM inserted into it anymore. Is there any way to fix it? I'd be willing to try to resolder parts on the board itself if need be. I'd like to exhaust all my options before having to buy a new board as that may no longer be in the budget :'(

Do you have a second RAM module you can try, just to help establish where the problem lies?

Edit: just seen your other thread where you've done this but it didn't work. Hopefully someone can suggest something to try with the DE-10 itself.

I don't know if jiggling the dip switches on the Nano would do anything related to the first memory slot. Those dip switches can develop a bad connection over time and switching them back and forth a couple of times can fix that.

Pictures of how the ram is fitted is needed. Then we can see if you are using the right socket and if you have the Ram facing the correct direction.

You should also ensure your dip switches are set correctly

I think my dip switches are setup correctly. I'll attach photos of my mister.

You should try without the USB board and the IO Board. Also remove that RTC unit, you have cracked the DE-10 socket when installing it which suggests its a cheapo Ali Express variant as they dont use the right connector.

As this is a retro device, you should take the memory out, blow on it and then plug it back in, then smack the side of the Mister.

Tried it with just the DE10-Nano, still doesn't recognize either ram :'(. I'll post a pic of it.
