ECC memory with GA-EX58-UD5

The memory support list is here:

and, of course, doesn't say - later today, I will search a number of the supported modules, as well as re-check the X58 specs to try to determine - hosed up for a while now - all day dentist trip

you can only use ecc memory with a xeon cpu, remember that the mem controler for new gen intel is onboard the cpu.

Correct. You CAN'T use ECC RAM with a non-server board. You'd need something like this if you want ECC:

Note: This board CAN use a normal i7. BUT most true server boards (esp. 2P) will need a Xeon.

The i7-920 won't support ECC memory no matter what motherboard you use. I'm using a Xeon W3520, which is identical to the i7-920 except that it supports ECC memory. I've paired it with an Asus P6T6 WS Revolution motherboard which also supports ECC memory, and in fact, am actually using ECC memory! It all works just fine.
