It's a little tricky to solder the SDRAM XS-D SDRAM modules, so I was wondering if you could solder one module at a time and run memtest to see if it soldered correctly?

If it tested OK, you could then solder the second module and if any errors occured you would know which module needed to be resoldered/fixed.

I read on on the old forum that you can install only U1 and caps and it will work as a 64 Mb board.
