I currently have a Gigabyte X58A-UD7 motherboard with the i7-990X CPU and non-ECC memory. I'm considering switching the CPU to the Xeon W3690. What I'm not clear about is whether or not I can use ECC memory in this motherboard or not. I know it has to be DDR3 and 1333 MHz. Does any memory manufacturer have ECC memory for this motherboard which will work?
