I think you can use the entire RAM by using the directive attribute ((section("AHBSRAM0"))) in this way
int var attribute((section("AHBSRAM0"))); to put the variables in the AHBSRAM0 memory section. notice: you can do this only if you don't use either the ethernet or CAN peripherals in you project. I hope it could be handy ;)

It has 64kb total RAM, of which 32kb is general purpose intended for your application, and the remainder is specifically for ethernet/usb/can? drivers.
