Gigabyte 7DX question

[ctk1981]

Anyone know if there are any problems using 2 256MB DDR 2100 ECC Registered chips in this board? Ram will be coming from Crucial anyway I cut it, just want to make sure that this board doesn't have any problems with using the registered ddr. User manual says it does, but once again..just checking to make sure.

Btw, GA-7DX Revision 4

Thanks
