I’m not sure where else to go with this, sorry if this isn’t the right place.

I’m currently designing a NAS build around an old CMB-A9SC2 motherboard that is self-described as an ‘entry level server board’.

So far i’ve managed to source all the other necessary parts, but i’m having a hell of a time finding the specified RAM that it takes:

• 204-pin DDR3 UDIMM ECC

As far as I can tell, that type of ram just doesn’t exist… I can find it in SODIMM formats or I can find it in 240-pin formats, but for the life of me I cannot find all of those specifications in a single card.

I’m about ready to just throw the whole board away, but everything else about the board is perfect…

Has anyone else dealt with this kind of memory before? Is there like a special online store where they sell weird RAM components meant for server builds?
