If you run the 'Shell' command line from your Workbench disk you can enter the 'Avail' command. it will most likely tell you around 1Meg of total memory.

Maximum is largest you could have without loading Workbench, in your case 1Meg (probably 512kB +512kB installed). This avail cmd is rather old, if you check with Sysinfo memory page what does it say?

It has only Chip RAM in its original configuration.

Yes.
Also, try to set date and time and check if it is remembered after switching the Amiga off for some 30 minutes or so.
Can you have a look at the expansion? If it has an unopened metal case you should consider open it up to remove the leaking Varta battery from hell.

Well it seems okay. To actually check the RAM you would need to run tests.
