Does T2080RDB support non ECC DRAM?

Can anyone confirm whether or not the T2080RDB works with non ECC DRAM? I tried replacing the SO-DIMM with one that is the same speed except it does not have ECC. I set ecc=off in the hwconfig variable in U-Boot. The ECC module works (and U-Boot prints out that ECC is turned off), however the non ECC module does not work. I used the ddr_interactive U-Boot variable to stop it in the boot process and look at the DRAM controller registers for both modules and they are the same. It seems to me that the board doesn't support non ECC modules for some reason but I would like to get a confirmation of this.
